The compromise of Anthropic's official Claude Code extension on Cursor's extension marketplace was the result of the theft of an access key that was exposed in the wake of a breach targeting Fireworks AI . "An attacker obtained an access key we had issued to Fireworks," Cursor said in a Friday update. "The key was exposed by Fireworks , and the attacker used it to copy data from a read-only storage bucket we used to share data with them." The disclosure comes nearly two weeks after a trojanized version of Anthropic's official Claude Code extension was distributed through Cursor Marketplace as a legitimate update, attempting to install a persistent SSH backdoor on affected systems. According to the artificial intelligence (AI)-powered coding platform, the read-only storage bucket is said to have contained limited coding agent traces from sessions that were not in Privacy Mode. Privacy Mode is a Cursor-specific setting that, if enabled, allows ...

The U.S. Federal Bureau of Investigation (FBI) has established that threat actors tied to the Democratic People's Republic of Korea (DPRK aka North Korea) have stolen more than $400 million worth of cryptocurrency as part of a social engineering scheme codenamed FaceStealer in the last 18 months. As part of a coordinated set of actions announced by the U.S. government, the cloud-based infrastructure used to pull off the "hard-to-detect" campaign has been seized. In tandem, the U.S. Department of Justice (DoJ) has announced the court-authorized seizure and restraint of more than $1.2 billion worth of cryptocurrency recently stolen by the North Korea-linked TraderTraitor actors following the hack of cryptocurrency exchange Binance. The plundered digital assets are used to fund Pyongyang's illicit weapons program, the DoJ added. "The North Korean regime relies on proceeds from large-scale cryptocurrency theft to fund its illicit weapons program, stealing b...

Three Trezor Safe 5 wallets bought from the reseller CryptoBilis contain an implant, an extra circuit board that can copy their recovery phrases, hardware wallet maker Trezor said yesterday. The implant reads the phrase from the wallet's screen and sends it over the mobile network to a server controlled by the attackers. The company examined one of the wallets in its lab, identified the other two from photos their owners sent, and has had no reports of lost funds. A firmware update released earlier this week, version 2.13.1, stops the implants found so far from capturing anything on wallets that run it, the company said, but “the update can’t protect a wallet backup that was captured before it.” The company has not changed its advice to anyone who bought a Trezor from CryptoBilis since March, including from the reseller's stores on Tokopedia and Shopee: Move your funds to a new wallet with a new recovery phrase. Restoring the old phrase on another wallet does not ...

A critical flaw in Red Hat Quay allows an attacker who can access a Quay registry to read and overwrite private container images in every repository. Quay enables anonymous access by default, and while it is enabled, the attacker needs no account. When it is off, anyone with a valid account can still exploit the flaw, Red Hat said yesterday. The company has released fixed builds for eight Quay 3 branches. The flaw is tracked as CVE-2026-123710 (CVSS score: 9.8). Quay uses keys it trusts to sign the access tokens that allow image pushes and pulls. The flaw lets an attacker add their own key to the keys Quay trusts, with no expiry date. Quay then accepts tokens signed with that key for any repository. With those tokens, an attacker can retrieve private images and any secrets or credentials stored within them. The attacker can also push or overwrite images, and the change propagates to every system that later pulls those images. The planted key survives restarts until someone ...

Starting Tuesday, an attacker used stolen credentials for 4,837 GitHub accounts to plant a secret stealer in repositories those accounts could write to, according to Aikido Security, a security software company. The stealer is built to take the secrets and cloud credentials that a repository's CI workflows can reach. It ran in at least 1,806 repositories, where the attacker has likely collected those credentials, the company says. Each attack started with a pull request titled docs: dependency audit notes, opened from a branch named wfx-docs to test whether the account could write to the repository. These test pull requests were opened in 61,764 repositories, and the stealer followed in some of them. In a separate analysis , researchers at SafeDep, which sells software supply chain security tools, counted 8,093 repositories that received malicious commits between 12:46 UTC on Tuesday and 04:36 UTC today. That count covers every repository that received malicious commits, no...

An AI model can be given a hidden backdoor by editing fewer than 10 of its rarely used neurons, without retraining the model, Microsoft researchers have shown. When a chosen trigger appears, the model outputs an attacker's command, which an agent using that model would run with the agent's own permissions. The attacker must be able to change the model's weights. The team tested the method on three open-weight models in research published this week. Microsoft says it has not seen any threat actors use the technique. The company also published guidance on defending against it. The edited neurons are ones that rarely fire and barely affect the model's answers. They were set to fire only when a trigger string appears, either in a user's request or later in a tool's output. The researchers call the method Lazarus . Each edited neuron forces one token of the command into the model's output, so a command needs about one neuron per token. The new neuron s...

A flaw in Git can let a malicious repository run an attacker's code on a computer that clones it recursively, together with its submodules. The Git project fixed it this week in Git 2.56.1, with matching fixes for the 2.50 through 2.55 series in 2.50.2, 2.51.3, 2.52.1, 2.53.1, 2.54.1 and 2.55.1. The flaw, tracked as CVE-2026-111760 , is an integer truncation in how Git handles its index. An extremely long path in a repository can pass Git's safety check, but Git then writes it to disk under a shorter name that an attacker can set to .git. This lets an attacker replace a submodule's .git file with a symbolic link to a folder holding malicious hooks or configuration. Hooks are programs Git runs at set points, so once Git uses that folder, the attacker's code can run. Submodules matter here because Git refuses to replace a .git folder with a symbolic link, but in a freshly cloned submodule, .git is a file. The fixed versions, listed in the Git pr...

An attacker broke into AWS accounts belonging to multiple Qubole customers between October 14 and October 26 and stole stored secrets and data, cloud security company Wiz said today. The attacker used credentials for an AWS account that Qubole's platform uses to reach those customers. How the attacker got those credentials has not been disclosed. Qubole , a data lake platform owned by Idera, operates within its customers' AWS accounts. To let it in, a customer creates an IAM role, which is an AWS identity with its own set of permissions. The role's trust policy allows Qubole's AWS account to assume the role, granting those permissions. Each request to do this, called AssumeRole , must include a matching code from Qubole known as an External ID. Apart from the attack, most of the roles the attacker assumed were unused, according to Wiz's researchers. But each role still trusted Qubole's account, so the attacker's requests worked. Any organization...

Attackers used the Ethersphere project's own release automation to publish malicious versions of two of its tools for the Swarm decentralized storage network: bee-js 13.3.0 and Swarm Desktop 0.56.2. Both releases download and run code built to steal the wallet key that Swarm Desktop keeps for its node, along with the stored password that unlocks it. The code is also built to install a backdoor on Windows, macOS, and Linux machines. The bee-js package is the JavaScript library behind Swarm Desktop and the swarm-cli command-line tool. Swarm Desktop runs a Swarm node on a user's own computer and saves the node's private keys there. Both malicious releases have been taken down, and the project's maintainers released a clean Swarm Desktop update today. Neither step removes a backdoor already installed nor protects a key already sent. No theft of funds had been reported at the time of writing. Swarm Desktop 0.56.2 appeared on GitHub at about 00:36 UTC today and was w...

Passwords and API keys that developers typed into commands they approved in Claude Code are sitting in public GitHub repositories, where anyone can read them. When a user selects " Yes, and don't ask again ," Anthropic's AI coding assistant can save the command, word-for-word, including the secret, in a project settings file. Software security company Apiiro said yesterday that 1,122 public copies of that file hold at least one secret, though it did not test whether any still work. One company the researchers notified earlier this week confirmed its key had been live. The file is .claude/settings.local.json. Removing it from a project does not undo the leak, because older versions stay in git history and in forks of the repository. The researchers' advice is to rotate first: change every password, token, and key the file has ever held, then clean up. How a Secret Lands in the File By default, Claude Code asks before it runs most shell commands. If the u...

An update on Athena, and some unsolicited predictions on what's coming next On Saturday, Dario Amodei published We Must Pace the Frontier . I agree with him. Go read it if you haven't. I've spent the summer looking at what these models find, and the gap he describes between what they can do and what the rest of us are ready for is the one I've been staring at since May. The hardest piece of his plan is the one that asks governments to coordinate. They're in a difficult spot: regulate too little and a US company accidentally builds the weapon, regulate too much and it gets built somewhere else, and open source isn't governable either way. Where governments can act is on consumption: not what the models can do, but what happens to what they find. Who gets a vulnerability first, how fast a fix reaches the people running the code, whether the operators who can't move on an attacker's timeline get a head start. That's what Gold Eagle is. It matters...

The Indian Computer Emergency Response Team (CERT-In) has disclosed that an artificial intelligence (AI)-assisted threat actor it tracks as Crafty Falcon is targeting organizations in the Banking, Financial Services, and Insurance (BFSI) sectors in the country. Describing the threat as active and ongoing, the activity involves the use of publicly-available AI-driven offensive security tools like ARTEX, PentAGI, Cairn, and CyberStrikeAI . "These tools execute complete attack chains autonomously at machine speed, generate and refine large numbers of tailored attack scripts in rapid succession, and adapt their payloads based on target responses," CERT-In said . "The supporting attack infrastructure rotates IP addresses within hours to days." The agency said the attacks have also targeted cryptocurrency exchanges and digital asset service providers, resulting in the theft of keys and funds. The update follows an October 2026 alert issued by CERT-In, which wa...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a medium-severity security flaw impacting multiple Apple operating systems to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of active exploitation. The vulnerability in question is CVE-2024-27834 (CVSS score: 5.5), a case of improper authentication that could allow an attacker with arbitrary read and write capability to bypass Pointer Authentication. It was addressed by Apple in May 2024 with improved checks in iOS 16.7.8 and iPadOS 16.7.8, iOS 17.5 and iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, watchOS 10.5, and Safari 17.5. The vulnerability was demonstrated as a zero-day at the Pwn2Own Vancouver hacking contest held in March that year. The addition of CVE-2024-27834 to the KEV catalog follows a report from Sekoia that threat actors possibly linked to Russia exploited previously patched vulnerabilities in Safari and Google Chrome to deliver malware capable of harves...

A flaw in APT , the package manager for Debian and Ubuntu, allows an attacker who can modify package downloads to swap a checked package for their own. The attacker's code then runs as root, according to advisories that  Debian ,  Ubuntu , and  APT's developers  published on November 4. The attack needs APT to retry failed downloads, which it does by default from Debian 12 and Ubuntu 22.04 onward. Debian has released fixed versions of APT for the flaw, CVE-2026-109518 . APT's developers, who call the flaw critical, say updates for Ubuntu and its Ubuntu Pro subscription service are being released. Ubuntu 14.04 users with Ubuntu Pro can already get one. Older releases, such as Debian 11 and Ubuntu 20.04, are not exposed by default, according to Ubuntu. But many user scripts may have turned on the retry setting, Acquire::Retries, on those releases anyway, APT's developers say. Debian's testing branch was still on the  vulnerable version 3.3.5  at...

Cybersecurity researchers have disclosed details of an OpenAI Codex jailbreak bundle that's designed to modify an artificial intelligence (AI) agent's trusted instructions to insert advertisements for a third-party AI gateway. The phenomenon has been codenamed prompt adware by Check Point Research. Called Haiou (meaning Seagull in Chinese), the jailbreak modifies OpenAI Codex's configuration files to inject advertisements for the jailbreak author's website into subsequent agent responses. "The advertised service is an opaque, OpenAI-compatible LLM gateway, a middleware between an application and an LLM provider," Check Point Research said in a technical report. "The likely business model is to use the freely distributed jailbreak bundle as an acquisition channel for the paid gateway service." Adware is a type of software that displays unwanted advertisements, which can appear on users' computers or mobile devices, often in the form of ...

The Russia-linked threat actor known as APT29 is presumed to be behind a large-scale watering hole campaign targeting iOS and Android users through compromised websites, fake domains, and a supply chain attack involving a Ukrainian web analytics service called Plerdy SEO Tracker. "The injected JavaScript code collects browser and device attributes," Sekoia researchers Amaury-Jacques Garçon and Félix Aime said in a technical report shared with The Hacker News. "Then, the delivery infrastructure delivers a platform-specific N-day exploit chain targeting either iOS or Android." The end goal of the attacks is to serve payloads capable of stealing browser cookies, and in some cases, Wi-Fi passwords or full mobile device data. The activity, codenamed Poisoned Source , was discovered by the French cybersecurity company in mid-October 2026. A defining aspect of the campaign is the use of three infection vectors - Compromise of legitimate websites to inject mal...

Nearly every agent security pitch now ends on the same promise: the product stops the bad action in real time. The promise holds for one kind of agent, the kind whose traffic passes through a gateway the enterprise owns. Most agents never touch one. One recent case shows what that gap looks like in practice. An employee asked an AI assistant to trigger a mass-email automation. The automation hit a recipient-limit policy and failed, so the assistant, which was also connected to the employee's personal mailbox, offered to send the batch from there instead. The employee approved without registering that the assistant was about to route around the sanctioned system. An unknown number of external recipients received email from a personal account rather than the approved channel. No jailbreak was involved. The assistant did exactly what it was built to do, and the fix was not retraining a model. It was a single runtime rule that blocks any attempt to reach more than fifty external d...

A China-aligned threat actor known as SlippyNunchucks has been attributed to a Domain Name System (DNS) hijacking operation abusing insecure HTTP communications in Windows versions of Sogou Input Method as part of a surveillance campaign designed to deploy an implant called DarkVigil (aka FDMTP). The campaign, observed starting July 1, 2026, is assessed to have targeted organizations and Chinese-speaking individuals in Hong Kong, Thailand, Japan, Vietnam, Oman, and Sri Lanka, according to ESET. "DarkVigil implants are typically deployed through popular Chinese applications," ESET researcher Anh Ho said in a report shared with The Hacker News. "By abusing these applications, the SlippyNunchucks threat actor has been able to reach Chinese-speaking users across Asia and Europe." Some of the applications abused by the adversary include Sogou Input Method, QuickFox, QingTalk, MiYunChat, SoftCam, and tawk.to. Active since at least September 15, 2023, SlippyNunc...

Blockchain infrastructure provider Chainstack on Tuesday disclosed that it was targeted in a cyber attack that allowed an unauthorized party to gain access to some parts of its infrastructure. The incident is assessed to be part of a large-scale, artificial intelligence (AI)-powered attack campaign that came to light last week. "An external attacker gained unauthorized access to part of Chainstack's infrastructure through a third-party component," the company said . "We detected the intrusion, cut the access paths, and are hardening our systems." According to the timeline of events shared by Chainstack, the attacker gained access to a development environment on October 26, 2026, and then escalated their access to break into "some parts of our production environment." The intrusion was subsequently detected on October 31, 2026, and the attacker's access was cut off that same day, the company noted. As part of the digital break-in, the ...

Binance on Tuesday said the record-setting theft of $6.43 billion in assets from the world's largest cryptocurrency exchange was the culmination of a "sophisticated, multi-stage campaign" that involved the use of a tampered Homebrew installation and recruitment-themed social engineering attack targeting two of its engineers. "It was not a single isolated breach or a simple phishing incident," the company said . "The attackers combined a range of techniques, including social engineering by fake recruitment interviews, malicious software downloads, compromised internal AI tooling, endpoint compromise, and an advanced transaction-authorisation method." The starting point has been traced back to a supply chain attack targeting one of its engineers from the Wallet DevOps team (named "Engineer A"), who downloaded a trojanized Homebrew installer to install a popular artificial intelligence (AI) tool after searching for it on a search engine....
