Intel SGX Can Be Abused to Hide Advanced Malware: Researchers

A team of researchers has demonstrated that Intel’s SGX technology can be abused to hide an advanced and stealthy piece of malware that could allow attackers to steal data and conduct activities on the victim’s behalf. Intel says its technology works as intended and it’s not designed to block these types of attacks.

Michael Schwarz, Samuel Weiser and Daniel Gruss of the Graz University of Technology in Austria have conducted an analysis of Intel SGX and the practicality of enclave malware. It’s worth noting that Schwarz and Gruss were also involved in the discovery of the notorious Meltdown and Spectre vulnerabilities.

Intel Software Guard Extension (SGX) is an isolated execution technology present in Intel processors. It’s designed to protect code and data against disclosure and changes – even if the system has been compromised – by allowing developers to partition their applications into hardware-protected memory regions called enclaves. The technology is advertised for cloud environments, digital rights management (DRM), secure browsing, and other applications.

Intel SGX can be abused by malwareWhile the technology can be highly useful, it can also be leveraged for malicious purposes. SGX enclaves can be ideal for hiding a piece of malware as they prevent antiviruses from inspecting code running in them, and cybercriminals could develop ransomware that stores encryption keys inside an enclave to make file recovery impossible.

Researchers demonstrated in the past that enclave malware can use side channels to steal sensitive information, but it has been assumed that there are serious limitations to what enclave malware can do. Some previously developed enclave malware relied on an application running on the host to perform malicious activities.

However, researchers from the Graz University of Technology have now shown that enclave malware can be practical and it does not necessarily need support from a malicious host application. They demonstrated how a piece of malware can bypass SGX restrictions and stealthily exploit a benign host application.

In the attack scenario described by the experts, the victim uses a trusted and secure system. The attacker delivers a benign application that uses a malicious enclave when executed. The host application communicates with the enclave through an interface that should not allow the enclave to attack the app.

However, despite serious restrictions, the researchers have demonstrated that it is possible to escape the enclave and achieve arbitrary code execution with host privileges even without exploiting any hardware flaws in SGX. The attack can even bypass exploit protections such as ASLR, stack canaries, and Address Sanitizer.

Theoretical attack scenarios described by the experts involve criminal threat actors delivering the malware as computer games requiring the execution of a DRM enclave, a messaging app that runs an enclave for security reasons, and a special decoder that allegedly needs an enclave to provide an interesting feature. In attack scenarios involving a state surveillance agency, the enclave malware is delivered via state-endorsed applications, such as digital signature tools.

Hackers could steal or encrypt files for ransom attacks, or they could perform actions on the victim’s behalf, including to send out phishing emails or launch denial-of-service (DoS) attacks, experts said.

Sophisticated threat actors may find this method useful as it can help them ensure that the zero-day vulnerabilities exploited in their attacks are not exposed if their malware is discovered. The method allows an attacker to trigger the exploit at a specified moment to prevent discovery before execution, which can be useful for large-scale synchronized threats such as botnets and ransomware.

“[Hiding] malware in an SGX enclave give attackers plausible deniability and stealthiness until they choose to launch the attack. This is particularly relevant for trigger-based malware that embeds a zero-day exploit, but also to provide plausible deniability for legal or political reasons, e.g., for a state actor. Possible scenarios range from synchronized large-scale denial-of-service attacks to targeted attacks on individuals,” the researchers explained.

“We conclude that instead of protecting users from harm, SGX currently poses a security threat, facilitating so-called super-malware with ready-to-hit exploits. Our results lay ground for future research on more realistic trust relationships between enclave and non-enclave software, as well as the mitigation of enclave malware,” they noted.

Contacted by SecurityWeek, Intel has thanked the researchers for their work and for coordinating disclosure of the method. However, the tech giant says the research is “based upon assumptions that are outside the threat model for Intel SGX.”

“The value of Intel SGX is to execute code in a protected enclave; however, Intel SGX does not guarantee that the code executed in the enclave is from a trusted source. In all cases, we recommend utilizing programs, files, apps, and plugins from trusted sources,” Intel said.

Microsoft patches 0-day vulnerabilities in IE and Exchange

Microsoft’s Patch Tuesday this month had higher-than-usual stakes with fixes for a zero-day Internet Explorer vulnerability under active exploit and an Exchange Server flaw that was disclosed last month with proof-of-concept code.

The IE vulnerability, Microsoft said, allows attackers to test whether one or more files are stored on disks of vulnerable PCs. Attackers first must lure targets to a malicious site. Microsoft, without elaborating, said it has detected active exploits against the vulnerability, which is indexed as CVE-2019-0676 and affects IE version 10 or 11 running on all supported versions of Windows. The flaw was discovered by members of Google’s Project Zero vulnerability research team.

Microsoft also patched Exchange against a vulnerability that allowed remote attackers with little more than an unprivileged mailbox account to gain administrative control over the server. Dubbed PrivExchange, CVE-2019-0686 was publicly disclosed last month, along with proof-of-concept code that exploited it. In Tuesday’s advisory, Microsoft officials said they haven’t seen active exploits yet but that they were “likely.”

Lest readers are tempted to think Microsoft is the only major software maker whose products have been actively exploited in recent weeks, Apple last week patched three iOS vulnerabilities that researchers said were being exploited as zero days in the wild. Two of those zero-days were discovered by Project Zero. Apple declined to comment.

In all, Microsoft patched more than 70 vulnerabilities, 20 of which were rated critical. Vulnerable products included IE, Edge, Windows, Office, the .NET Framework, Exchange Server, Visual Studio, the Azure IoT SDK, Microsoft Dynamics, Team Foundation Server, and Visual Studio Code. Microsoft has an overview here.

Microsoft Patches Internet Explorer Zero-Day Reported by Google

Microsoft’s Patch Tuesday updates for February 2019 address more than 70 vulnerabilities, including an Internet Explorer flaw that Google researchers have spotted being exploited in attacks.

This zero-day vulnerability is tracked as CVE-2019-0676 and it has been described by Microsoft as an information disclosure issue that exists due to the way Internet Explorer handles objects in memory.

An attacker can exploit the flaw to test for the presence of files on the targeted device’s disk, but the victim must be tricked into opening a malicious website using a vulnerable version of Internet Explorer.

The security hole impacts Internet Explorer 11. Microsoft has recently advised users to stop using IE as their default browser due to the security risks associated with the application, which the tech giant now describes as a “compatibility solution.”

Microsoft has credited Clement Lecigne of Google’s Threat Analysis Group for reporting the vulnerability. It’s worth noting that Lecigne was also credited by Microsoft in December for reporting a remote code execution flaw in Internet Explorer 9 and 11 (CVE-2018-8653) that had also been exploited in attacks when a patch was released.

No details have been shared about these attacks, but since CVE-2018-8653 had been exploited in targeted attacks, chances are that it’s the same with CVE-2019-0676 as well.

It’s also worth noting that Lecigne was credited by Apple last week for two iOS zero-day vulnerabilities that had been exploited in the wild.

Microsoft’s latest security updates also resolve several vulnerabilities whose details were made public before a patch was released. The list includes a privilege escalation issue related to Exchange Server, which a researcher disclosed in late January.

One information disclosure flaw in Windows and two Team Foundation Server weaknesses were also marked by Microsoft as “publicly disclosed.”

Trend Micro’s Zero Day Initiative has analyzed all the advisories published by Microsoft and reports that 20 vulnerabilities have been described as “critical” and 54 as “important.” The critical flaws impact Internet Explorer, Edge, SharePoint, and Windows, and they all allow remote code execution.

Adobe’s Patch Tuesday updates resolve vulnerabilities in Acrobat and Reader, Flash Player, ColdFusion and Creative Cloud. The details of one flaw impacting Reader were made public in late January.

Adobe Patches Disclosed Data Leakage Flaw in Reader

Adobe on Tuesday released patches for Acrobat and Reader, Flash Player, ColdFusion and Creative Cloud. One of the Reader flaws is a critical data leakage issue whose details were made public by a researcher in January.

The company has resolved a total of 71 vulnerabilities in Acrobat and Reader products. One of them has been described as an information disclosure problem that can lead to sensitive data getting leaked.

The flaw was detailed in a blog post published in late January by researcher Alex Inführ, who showed how it can be exploited by a specially crafted PDF document to send SMB requests to the attacker’s server when the file is opened.

The vulnerability is similar to CVE-2018-4993, which Adobe patched last year. It allows a remote attacker to steal a user’s NTLM hash included in an SMB request, and it can be leveraged to alert an attacker when their malicious PDF document has been opened by the targeted user.

0patch, which creates third-party fixes for unpatched vulnerabilities, released an unofficial patch for this issue on Monday, one day before Adobe released its security updates. This micropatch alerts the user when a document attempts to connect to a remote server and allows them to block the connection before any data is sent.

Adobe told SecurityWeek that it has assigned the CVE 2019-7089 identifier to this vulnerability. The company says it’s aware of the publicly available “technical write-up” for this security hole.

This is the second time Adobe patches a vulnerability similar to CVE-2018-4993.

The other weaknesses patched by Adobe on Tuesday in Acrobat and Reader include many critical arbitrary code execution flaws caused by memory corruption bugs.

In Flash Player, which will receive security updates until the end of 2020, Adobe patched only one “important” vulnerability that can result in information disclosure.

Two flaws – one that allows code execution and an XSS bug that can lead to information disclosure – have been resolved in ColdFusion. One vulnerability has also been patched in the installer of the Creative Cloud desktop application.

Adobe says it’s not aware of in-the-wild exploits for any of the vulnerabilities fixed with its February 2019 Patch Tuesday updates.

Container Escape Flaw Hits AWS, Google Cloud, Linux Distros

A vulnerability recently addressed in runc could allow malicious containers to gain root-level code execution on the host.

Introduced in 2015, runc is a lightweight, portable container runtime that includes all of the code used by Docker to interact with system features related to containers. The runtime is used in most containers out there, including cri-o, containerd, Kubernetes, Podman, and others.

Tracked as CVE-2019-5736 and featuring a CVSSv3 score of 7.2, the vulnerability can be exploited with minimal user interaction, senior software engineer at SUSE Linux and runc maintainer Aleksa Sarai says.

Discovered by Adam Iwaniuk and Borys Popławski, the vulnerability could allow a malicious container to overwrite the host runc binary and execute code on the host.

The bug can be triggered when creating a new container using an attacker-controlled image, or when attaching to a running container (using docker exec) that the attacker previously had write access to.

“Exploiting this vulnerability means that malicious code could potentially break containment, impacting not just a single container, but the entire container host, ultimately compromising the hundreds-to-thousands of other containers running on it,” Scott McCarty, Red Hat principal product manager for containers, says.

The use of SELinux in targeted enforcing mode prevents this vulnerability from being exploited. However, the default AppArmor policy and the default SELinux policy on Fedora (only the moby-engine package) fail to prevent the bug, Sarai says.

Only privileged containers (root privilege on the host is required) can exploit the flaw (unprivileged containers with a non-identity ID mapping don’t have permission to write to the host binary).

The vulnerability impacts runc releases through 1.0-rc6, as used in Docker before 18.09.2 and other products. The vulnerability occurs because of file-descriptor mishandling, related to /proc/self/exe.

Red Hat, Debian and Ubuntu are impacted by the flaw. Amazon and Google too published advisories, confirming the vulnerability in their products. LXC is also affected by the flaw.

A GitHub repository was created to provide a backport of patches for older versions of runc that were packaged with Docker.

Exploit code for the vulnerability is expected to be published within a week. A Shodan search shows that there are nearly 4,000 exposed Docker daemons on the internet.

Tenable Adds ‘Predictive Prioritization’ to Vulnerability Management Offering

Tenable on Monday announced the general availability of a new service designed to help organizations identify the vulnerabilities that have the highest likelihood of being exploited.

Predictive Prioritization is currently available for Tenable customers using the Tenable.sc on-premises vulnerability management solution, but it will be added to Tenable.io, the cloud-based version, later this year.

The cybersecurity firm has pointed out that of the more than 16,000 new vulnerabilities disclosed in 2018, only 7 percent had an exploit available and Tenable estimates that only 3 percent will actually be exploited.

Many experts agree that prioritizing patching based on CVSS scores can be highly ineffective – the method creates a vulnerability overload and places a lot of pressure on security teams.

Tenable’s new Predictive Prioritization service aims to address this by helping organizations identify those 3 percent of security holes that are actually likely to be exploited in attacks.

Using data from over 150 sources, Predictive Prioritization helps calculate a vulnerability priority rating (VPR) for each vulnerability. Unlike the CVSS score, which is static, the VPR is updated daily based on the latest threat information and it helps predict if a flaw will be exploited in the next 28 days.

“Predictive Prioritization is a massive innovation in vulnerability management. It will change the way companies run their vulnerability management programs by giving them a new level of insight on where to focus based on threats to the business,” said Renaud Deraison, co-founder and CTO of Tenable. “Predictive Prioritization is unprecedented in the vulnerability management market and will help organizations answer foundational questions about where they’re exposed and what vulnerabilities to prioritize for remediation based on the threat landscape — two questions that are critical for achieving Cyber Exposure.”

Undercover Spy Exposed in NYC Was 1 of Many

LONDON (AP) — When mysterious operatives lured two cybersecurity researchers to meetings at luxury hotels over the past two months, it was an apparent bid to discredit their research about an Israeli company that makes smartphone hacking technology used by some governments to spy on their citizens. The Associated Press has now learned of similar undercover efforts targeting at least four other individuals who have raised questions about the use of the Israeli firm’s spyware.

The four others targeted by operatives include three lawyers involved in related lawsuits in Israel and Cyprus alleging that the company, the NSO Group, sold its spyware to governments with questionable human rights records. The fourth is a London-based journalist who has covered the litigation. Two of them — the journalist and a Cyprus-based lawyer — were secretly recorded meeting the undercover operatives; footage of them was broadcast on Israeli television just as the AP was preparing to publish this story.

All six of the people who were targeted said they believe the operatives were part of a coordinated effort to discredit them.

“There’s somebody who’s really interested in sabotaging the case,” said one of the targets, Mazen Masri, who teaches at City University, London and is advising the plaintiffs’ attorney in the case in Israel.

Masri said the operatives were “looking for dirt and irrelevant information about people involved.”

The details of these covert efforts offer a glimpse into the sometimes shadowy world of private investigators, which includes some operatives who go beyond gathering information and instead act as provocateurs. The targets told the AP that the covert agents tried to goad them into making racist and anti-Israel remarks or revealing sensitive information about their work in connection with the lawsuits.

NSO has previously said it has nothing to do with the undercover efforts “either directly or indirectly.” It did not return repeated messages asking about the new targets identified by the AP. American private equity firm Francisco Partners, which owns NSO, did not return a message from the AP seeking comment.

The undercover operatives’ activities might never have been made public had it not been for two researchers who work at Citizen Lab, an internet watchdog group that is based out of the University of Toronto’s Munk School.

In December, one of the researchers, John Scott-Railton, realized that a colleague had been tricked into meeting an operative at a Toronto hotel, then questioned about his work on NSO. When a second operative calling himself Michel Lambert approached Scott-Railton to arrange a similar meeting at the Peninsula Hotel in New York, Scott-Railton devised a sting operation, inviting AP journalists to interrupt the lunch and videotape the encounter.

The story drew wide attention in Israel. Within days, Israeli investigative television show Uvda and The New York Times identified Lambert as Aharon Almog-Assouline, a former Israeli security official living in the plush Tel Aviv suburb of Ramat Hasharon.

By then, Scott-Railton and the AP had determined the undercover efforts went well beyond Citizen Lab.

Within hours of the story’s publication, Masri wrote to the AP to say that he and Alaa Mahajna, who is pursuing the lawsuit against NSO in Israel, had spent weeks parrying offers from two wealthy-sounding executives who had contacted them with lucrative offers of work and insistent requests to meet in London.

“We were on our guard and did not take the bait,” Masri wrote.

Masri’s revelation prompted a flurry of messages to others tied to litigation involving NSO. Masri and Scott-Railton say they discovered that Christiana Markou, a lawyer representing plaintiffs in a related lawsuit against NSO-affiliated companies in Cyprus, had been flown to London for a strange meeting with someone who claimed to be a Hong Kong-based investor. Around the same time, Masri found out that a journalist who had written about NSO was also invited to a London hotel — twice — and questioned about his reporting.

“Things are getting more interesting,” Masri wrote as the episodes emerged.

Like Almog-Assouline, the undercover operative the AP exposed in New York, the covert agents who pursued the lawyers made a string of operational errors.

The attempt to ensnare Alaa Mahajna, the lead lawyer in the Israeli suit, was a case in point.

On Nov. 26 he heard from a man who said his name was Marwan Al Haj and described himself as a partner at a Swedish wealth management firm called Lyndon Partners. Al Haj offered Mahajna an intriguing proposition. Al Haj said one of his clients, an ultra-rich individual with family ties to the Middle East, needed legal assistance recovering family land seized by Jewish settlers following the 1967 Arab-Israeli war.

“I believe you may be a good fit for this challenging task,” Al Haj wrote.

The request made sense. As a human rights lawyer based in Jerusalem, Mahajna has defended Palestinian activists and others at the receiving end of the Israeli government’s ire. But Mahajna became suspicious as he tried to learn more about the case. Al Haj was cagey about his client and seemed unwilling to provide any paperwork, Mahajna told the AP.

“Not even the basic stuff,” Mahajna said. “Usually people flood you with documents and stories.”

Mahajna said he was unsettled when Al Haj suddenly offered him an all-expenses-paid trip to London; no one had even asked him whether the case had any hope of success.

“At some point it was abundantly clear that this is not a bona fide approach,” Mahajna said.

Ten days later, Masri, the legal adviser in the Israeli lawsuit, received an email offering him a place on the advisory board of a Zurich-based company called APOL Consulting.

Masri became skeptical after he checked out the company’s website. Consulting firms typically trade on their employees’ intelligence and skill, so Masri expected the company’s site to prominently display the names, headshots and qualifications of its staff.

“Here there wasn’t even a name of one human,” he said.

When Masri turned down the position on APOL’s board, the representative who’d contacted him — a man who called himself Cristian Ortega — pressed Masri to see him in London anyway.

“I would consider it a privilege to have a chance to meet you in person for a friendly chat,” Ortega said in a Jan. 7 email. “No strings attached of course.”

Masri said that by then he and Mahajna had come to believe that Ortega and Al Haj were fictions and that their companies were imaginary.

But they didn’t yet know how widespread the covert operations were.

The undercover agents got a little further with Christiana Markou, the lawyer who is pursuing the Cypriot case against NSO-affiliated entities.

Her lawsuit, like Mahajna’s, draws heavily on reports by Citizen Lab that found that NSO spyware had been used to break into the phones of the Mexican activists and journalists who are the plaintiffs in both cases.

Markou told the AP she was approached over email Dec. 21 by a man who presented himself as Olivier Duffet, a partner at Hong Kong-based ENE Investments.

Duffet was ostensibly interested in inviting Markou — a leading data protection and privacy lawyer in Cyprus — to give a lecture at a conference. Markou said she proposed discussing the lecture over Skype, but he insisted on an in-person meeting in London, eventually flying her out, putting her up in a fancy hotel and chatting for a little more than an hour.

Most of the discussion revolved around the proposed lecture — but then Duffet suddenly pivoted to the NSO case, asking her whether she felt the lawsuit was winnable and who was funding it.

Markou said she “gave either incorrect answers or expressly refused to answer” because she found his questions suspicious.

Yet another target, Eyad Hamid, a London-based journalist who wrote a story about NSO, said he was also invited to a London hotel on two separate occasions to discuss his coverage of the Israeli company.

The purported company used in the operation targeting him was Mertens-Giraud Partners Management, which was described as a Brussels-based wealth management firm.

Neither MGP — nor any of the other companies — truly existed. The AP’s searches of the Orbis database of some 300 million companies, local corporate registries and trademark repositories turned up no trace of a Swiss firm called APOL, a Swedish company called Lyndon partners, a Belgian company called Mertens-Giraud or a Hong Kong-based firm named ENE Investments. Local phone books didn’t carry listings for a Zurich-based man named Cristian Ortega, a Hong Kong-based man named Olivier Duffet or anyone in Sweden bearing the name Marwan Al Haj.

There was no hint of APOL when the AP visited its supposed office not far from Zurich’s central train station; tenants said they’d never heard of the company. It was the same story in Hong Kong; a management representative at the Central Building, where ENE Investments was supposedly located, said he didn’t know anything about the company. An AP journalist wasn’t able to speak to anyone at Mertens-Giraud’s alleged office on Brussels’ Rue des Poissoniers; the entire building was boarded up for renovations.

At the modern office block in downtown Stockholm where Lyndon Partners claimed to have its headquarters, service manager Elias Broberger said he could find no trace of the wealth management firm.

“It says they are located here,” Broberger said as he examined Lyndon Partners’ professional-looking website. “But we don’t have them in any of our systems: not the booking system; not the member system. We don’t bill them; they don’t bill us.

“I can’t find them.”

Who hired the undercover agents remains unclear, but their operational and digital fingerprints suggest they are linked.

The six operatives all began approaching their targets around the same time with individually tailored pitches. Their bogus websites followed the same patterns; all of them were hosted on Namecheap and many were bought at auction from GoDaddy and used the Israeli web design platform Wix. The formatting of the websites was similar; in at least two instances — MGP and Lyndon Partners — it was identical. Even the operatives’ email signatures were the same — consisting of three neatly packed, colorful lines consisting of a phone number, web address and email.

The operatives’ LinkedIn pages were similar, too, featuring men in sunglasses shot from a distance, facing away from the camera, or at unusual angles — a tactic sometimes use to frustrate facial recognition algorithms.

Despite the indications that the undercover agents are all linked, there is no conclusive evidence who they might work for. An Israeli television channel, Channel 12, broadcast a report on Saturday claiming that an Israeli private investigation firm, Black Cube, had been investigating issues around the lawsuits against NSO. The TV channel showed secretly shot footage of the Cypriot lawyer, Markou, and the London journalist, Hamid, which matched the pair’s description of their encounters with undercover agents.

The TV segment was critical of the lawyers suing NSO, and quoted NSO founder Shalev Hulio in an interview accusing Markou and her colleagues of pursuing the lawsuits as a “PR exercise.”

NSO has previously denied hiring Black Cube, and Black Cube in a letter sent last month to the AP said it was not involved in the effort to ensnare researchers at Citizen Lab. “Black Cube had nothing to do with these alleged events,” the letter said, adding that no one acting on the company’s behalf did either.

Black Cube does have a possible tie to Almog-Assouline, the man who held the hotel meeting about NSO in New York. During a long-running Canadian legal battle between two private equity firms — Catalyst Capital and West Face Capital — one man caught up in the litigation said he recognized Almog-Assouline because he’d been approached by the same operative under a different identity several years ago.

“I recognized the individual, down to the accent and the anecdotes,” said the man, who spoke on condition of anonymity for fear of retaliation.

In court filings, Black Cube has acknowledged dispatching agents to meet with “various individuals” involved in in the private equity firms’ feud. But it’s unclear if other investigations firms might also have done work connected to the two companies’ legal battle.

Black Cube did not respond to repeated questions about whether it had ever employed Almog-Assouline. The firm previously drew international opprobrium for its unrelated work protecting the reputation of disgraced Hollywood mogul Harvey Weinstein.

Almog-Assouline himself denied working for Black Cube when two AP reporters confronted him in New York last month.

He has refused to answer any questions since.

When an AP reporter rang the door at his penthouse in Tel Aviv suburb of Ramat Hasharon a week ago, a woman who identified herself as his wife said he wasn’t home. When the reporter followed up with a phone call to Almog-Assouline, he said: “I have no interest in speaking to you.”

Aron Heller in Ramat Hasharon, Israel, David Keyton in Stockholm, Sweden, Jamey Keaten in Zurich, Vincent Yu in Hong Kong, Sylvain Plazy in Brussels, Josef Federman in Jerusalem and Meneloas Hadjicostis in Nicosia, Cyprus, contributed to this report.

Bezos Case Exposes Billionaires’ Vulnerability to Hackers

The stunning revelation that a tabloid obtained below-the-belt selfies of Amazon founder Jeff Bezos — the world’s richest man — suggests that even billionaires are not out of the reach of hackers.

Bezos came out fighting this week, accusing the National Enquirer of blackmailing him with lurid pictures of him and his mistress, and pre-empting the threat to publish by releasing details of the images himself.

But for Mark Johnson, CEO of Sovereign Intelligence, the incident makes clear that “no one is beyond the reach of cyber exploitation.” 

“It’s a curious irony that billionaires demonstrate astounding acumen related to their own industries, and yet seemingly ignore the minutiae of common-place security measures.” 

Johnson sees billionaires and top executives as especially vulnerable because their personal information is a gold mine for criminals, intelligence agencies and competitors.

“Obtaining their personal data is like having keys to the kingdom,” said Johnson, potentially providing priceless insight into the thinking and strategies of the world’s most powerful business leaders.

Ian Bremmer, the founder of the Eurasia Group think tank, put it more bluntly.

“If the National Enquirer has @JeffBezos dick pics, don’t tell me China doesn’t have @Amazon IP and strategy,” he tweeted.

– Increase in calls –

Since the revelations about Bezos, whose fortune is estimated at more than $130 billion, computer security experts interviewed by AFP report an increase in calls from wealthy clients asking them to verify that their computer systems and devices were not hacked.

“Today’s threats however are not necessarily trying to breach the walls of the castle — they are already inside, residing on personal devices,” said Kris Coleman, the founder of Red Five Security. “Experience has shown that the typical breach is not discovered for eight months.”

In this ever-more connected age, more and more personal data is stored online — from social security numbers to bank details, driver’s license numbers and personal addresses.

As a result the focus of security measures for the ultra-wealthy has shifted from bodyguards and sophisticated alarms towards risk management to protect their assets, their image and their “legacy.”

The super-wealthy will typically have their own computer security service and also call on external companies for regular evaluation of their devices because a large number of hacks are detected by third parties, according to observers.

Mark Zuckerberg, Facebook’s CEO, spent $7.3 million on his security in 2017, up from $4.2 million in 2015 — astronomical sums that the social network deemed justified due to his prominence.

Last July, Facebook said it would give him $10 million more per year to strengthen his security.

“Protection from colluding insiders working from positions of trust; or, against an intelligence agency trying to attack from the outside is going to require a large investment, a lot of experience, and vigilance,” said Coleman.

– Entourage –

For Johnson, “no one’s data is that well protected. Think of all the third-party platforms that have your social security number, or banking information, or that hold your personal pictures.”

Just days before Bezos disclosed that a tabloid had obtained his intimate selfies, a fellow billionaire — Joe Ricketts, the founder of the broker TD Ameritrade Holding Corporation — was ensnared in scandal following the release of private messages.

The American news site Splinter published a series of racist emails from Ricketts, without saying how it obtained them.

The exchanges, some of which date back to 2009, show the 77-year-old sharing and apparently endorsing racist jokes and conspiracy theories. He has since apologized.

Back in August 2015, a cyber attack on the Ashley-Madison extramarital dating site revealed that American billionaire Dan Loeb had an account there.

Bezos did not say how the National Enquirer obtained his pictures, but experts say the most common method is for a hacker to usurp the identity of a member of a person’s entourage.

“The adversary would send a message to the target asking them to click on a link in a text or email,” Coleman explained. “The sender’s real identity is hidden but the target trusts the message from their ‘friend’ and clicks the link unlocking malware or another type of attack on that device.”

Refrigeration Systems Used by Supermarkets, Hospitals Left Exposed Online

Thousands of instances of a temperature control system are exposed to remote attacks from the internet due to users’ failure to change default passwords and implement other security measures.

Researchers from Safety Detective discovered recently that refrigeration systems made by Resource Data Management (RDM), a Scotland-based provider of control and monitoring solutions, can be easily hacked from the internet. The experts say the vulnerable systems are housed by organizations from all around the world, including healthcare providers and major supermarket chains such as Marks & Spencer, Ocado and Way-On.

A Shodan search reveals over 7,400 devices accessible directly from the web, including many in Russia, Malaysia, Brazil, the United Kingdom, Taiwan, Australia, Israel, Germany, the Netherlands, and Iceland.

According to the researchers, the exposed systems can be accessed over HTTP on port 9000 (in some cases over ports 8080, 8100 or 80), and they are only protected by a known default username and password combination. The web interface can in many cases be accessed without authentication, but the password is needed when making changes to the settings.

Some of the systems can be easily identified via a simple Google search. Using Google and Shodan, researchers identified several types of impacted organizations, including a cold storage facility in Germany, a hospital and supermarkets in the UK, a pharmaceutical company in Malaysia, a food storage facility in Iceland, and an Italian food company.

If an unauthorized user gains access to one of these systems, they can, among other things, change refrigerator, user and alarm settings. This can pose a serious risk in the case of supermarkets and cold storage facilities, where activating the defrost function could result in financial damage (i.e. spoiled products). The risk is even bigger in the case of hospitals, where refrigerators can store blood, organs and vaccines.

“The systems can be accessed through any browser. All you need is the right URL, which as our tests show, isn’t too difficult to find. We will not go into detail here, as it is not our intention to encourage the hacking of systems that could literally put lives at risk, but all it takes is a simple Google search,” explained Safety Detective’s Paul Kane.

Safety Detective contacted RDM, but the vendor initially did not take its findings seriously and asked the researchers to refrain from contacting them again. RDM later thanked Safety Detective, but blamed users and installers for the situation.

Contacted by SecurityWeek, RDM noted that only less than 50 of the 7,000 systems visible from the internet are on private networks and located behind a firewall. The company has urged customers and entities in charge of installing the temperature control system to ensure that the default password has been changed.

“To clarify the situation from RDM we would confirm that the default passwords must be changed by the installer at the time of setup. RDM does not have any control over where our systems go and who install them. We clearly state in our documentation that the default passwords MUST be changed when the system is installed. Its similar to an off the shelf router with default user names and passwords Admin Admin,” an RDM representative explained.

“We would also point out that we do not have remote connectivity to many systems and even though it is possible to upgrade our software remotely we are unable to do this without the consent of the owner. We will inform owners that we have new software available with new functions and features but ultimately it is up to them to request an upgrade which can be done via USB locally or by there installer / maintainer remotely,” they added.

Site Isolation is Coming to Firefox

Mozilla is getting ready to boost the security of Firefox users with the addition of Site Isolation in the not too distant future. 

Dubbed Project Fission, the initiative aims to split cross-site iframes into different processes than their parent frame, marking a major step in the evolution of Firefox’s process model. 

The goal, Mozilla developer Nika Layzell says, is to protect not only against known vulnerabilities, but also against potential future vulnerabilities. 

The initiative is a reaction to Spectre and Meltdown, major CPU security vulnerabilities revealed last year and found to impact almost all modern processors. The bugs could lead to exfiltration of secrets stored in memory of other running programs via side channels, including cryptographic keys and passwords.  

The timing attack posed a serious threat to browsers, mainly due to the fact that webpages often serve JavaScript from multiple domains that run in the same process.

“We were able to mitigate these vulnerabilities right away. However, these mitigations may not save us in the future if another security vulnerability is released exploiting the same underlying problem of sharing processes (and hence, memory) between different domains, some of which may be malicious,” Layzell notes. 

Google has already addressed such concerns with the introduction of Site Isolation in Chrome at the end of 2017, and Mozilla is currently working on making a similar move with Project Fission, which has been under development for the past year. 

“In the coming weeks and months, we’ll need help from all Firefox teams to adapt our code to a post-Fission browser architecture. Fission is a massive project, spanning across many different teams, so keeping track of what everyone is doing is a pretty big task,” Layzell says. 

With much of the initial infrastructure ground work already done, Mozilla is moving to keeping track of Project Fission’s evolution in milestones (collections of new features and improved functionality), with Milestone 1 currently targeted for the end of February. 

However, Layzell hasn’t yet provided an estimated availability date for Site Isolation in Firefox.
