Cybersecurity researchers have disclosed Go-based malware distributed via two Go Modules and two Terraform providers, marking the first time threat actors are using the centralized repository hosted by HashiCorp as a distribution vector for malicious payloads. According to Aikido , the list of Terraform providers and Go modules is below - gocommunity-io/dockerd (222 downloads) kreuzwenker/docker (1,449 downloads) gocommunity.io/orderedbtree gogets.dev/btreex The malware deployed through these packages demonstrates overlaps with Graphalgo , a campaign that was first documented by ReversingLabs earlier this February and attributed to North Korean (aka DPRK) threat actors. As part of this effort, prospective developers are approached via social platforms like LinkedIn and Facebook, or through job offerings on forums by posing as non-existent Web3 companies, and then asked to complete a coding task by providing a benign GitHub repository that introduces the malicio...

The private email address GitLab gives you for filing issues by email is a credential. Anyone who gets it can email a patch that GitLab commits in your name, to any branch you can push to, including main, and can start CI/CD jobs that run as you. GitLab shows each user this address behind a button labeled "Email work item to this project." Mail sent to it opens an issue in that project, authored by you. The string in the middle of the address is a token tied to your account, and GitLab's documentation says it does not expire. The address looks like it belongs to one project. It does not.  Aikido Security , which reported the behavior, found that the addresses GitLab creates for a user's different projects all share the same token, and that the token applies to every project the account can open, public or private. GitLab does not check who sent the email. Any mailbox can write to the address, and GitLab acts on the message as if it came from you. Whoever holds...

Two MikroTik RouterOS SSH vulnerabilities chained together let attackers take full administrative control of Internet-exposed routers without a password, SSH key, or completed authentication. The chain, which CERT Polska calls MikroTrick , combines an SSH state-machine flaw ( CVE-2026-67279 ) with an argument-injection bug in the RouterOS login process ( CVE-2026-86060 ). Attack logs date to at least September 2, one day before MikroTik shipped patches in RouterOS 6.49.21, 7.23.4, and 7.24.2. As  previously reported , CERT Polska warned on September 5 that attackers were using RouterOS flaws to take control of devices whose SSH service was reachable from public networks. That warning confirmed the exploitation and urged immediate patching but did not identify which two flaws formed the chain or explain how they combined. This latest analysis provides both. How the Chain Works SSH requires three steps in order: it establishes an encrypted connection, authentica...

A Windows malware called CLOSEDQUORUM is built to take orders from a vote of up to four AI models instead of an attacker's server, Cisco Talos said on September 22. The models can choose to steal Windows credentials, saved browser passwords, and crypto wallet data. Talos has not seen this setup work from start to finish, and the public version of the malware does not work as it is. Talos found the malware with  CAIRN , an open-source tool it released the same day to hunt for malware that uses AI services. The malware is at least three months old, because Talos's analysis of the code is dated June 17, 2026. The researchers did not describe how the malware would get onto a victim's computer. It said clues in the code tied the developer to criminal forum posts about carding, the trade in stolen card data, dating to 2025. How the AI Vote Works Malware usually takes orders from a command-and-control (C2) server that the attacker runs. CLOSEDQUORUM instead asks up t...

Unknown threat actors have managed to compromise two legitimate MemTensor packages across the npm and Python Package Index (PyPI) repositories to push a platform-specific Go-based implant dubbed sckit designed for Windows, Linux, and macOS. According to reports from Aikido , SafeDep , Socket , and StepSecurity , the libraries in question below - @memtensor/memos-cloud-openclaw-plugin versions 0.1.21, 0.1.23 and 0.1.25 (versions 0.1.22 and 0.1.24 are clean) MemoryOS version 2.0.34 (project currently quarantined on PyPI) The malicious npm package versions include a "hidden Go payload into a legitimate AI memory integration. Versions 0.1.21, 0.1.23, and 0.1.25 contain code that launches the payload when the agent gateway starts and whenever the plugin handles a memory-recall event," StepSecurity said. "The launcher passes the host process environment and, during recall, the user's prompt text directly to the malicious executable."

A flaw in cPanel's  CalDAV and CardDAV service  lets anyone with a cPanel hosting account run code as root and take "full control of the server," the company said on September 22. A  second bug in the WP Toolkit plugin, used to install and manage WordPress sites, allows an account holder to change databases that belong to other accounts. cPanel has released fixed versions for both, along with a fix for a  third flaw  in the same service, which stores each account's calendars and contacts. That third flaw lets a local user on the server read other accounts' calendar events and contacts, but not change them or gain root access. cPanel lists no requirements for the root flaw other than having an account. On a shared server where a hosting provider sells accounts to the public, that means any customer could use it. So could anyone who gets hold of a customer's login. The three flaws and the versions that fix them:

Autonomous security agents are getting good at finding bugs. Nobody has a good way to measure how good. Point one at a realistic target and what comes back is a report the agent wrote about itself: confident prose, a list of findings, and no way to tell which of them happened. Someone with a security background then sits down and checks every claim against the target. Which findings are real, which are duplicates, which are inventions, and, the question nobody has time for, what did the agent never try? That is a day of expert work for one run. Multiply it by three models, four prompt variants and ten repetitions, and the review queue is longer than the experiment. XRanges for AI, built by CTF.ae, exists for that loop. It deploys realistic target applications with instrumentation baked into every service, records what an agent actually does inside them, and scores each run live on four independent signals. This walkthrough covers how it works, what a run looks like from deployment t...

Anthropic and OpenAI on Tuesday announced new models, with both artificial intelligence (AI) companies noting that they are continuing to invest in improving alignment to combat risky behavior. Opus 5.5, per Anthropic , is a "major step up from Opus 5," and "achieves the best scores of any model to date on our automated behavioral audit, our alignment suite that tests Claude across thousands of simulated scenarios." The AI company said the model is less likely than its other recent models to carry out hard-to-reverse actions or act outside the boundaries it's been given, adding it's more resistant than Opus 5 to prompt injection. In its systems card, Anthropic explained that the latest model exhibited less misaligned behavior and less cooperation with misuse than any other recent Claude model. "It also took overeager or destructive actions less than any other model we tested," Anthropic said. "Regressions included being more likely ...

A use-after-free in the Linux kernel's AF_UNIX socket subsystem can be used to escape a container and gain root on the host, security firm DepthFirst  said in research published September 22. The flaw, tracked as  CVE-2026-80521  (CVSS score: 7.8), was fixed upstream on August 6, but Ubuntu has not shipped the patch for its 26.04, 24.04, or 22.04 LTS releases. DepthFirst  released exploit code  targeting Ubuntu 26.04. Ubuntu's security tracker  lists the Linux package on 26.04 as "vulnerable, work in progress." The 24.04 and 22.04 releases are also affected through newer kernel packages, including those for AWS, Azure, and GCP workloads. No fix has shipped on any affected release. The flaw is not in CISA's Known Exploited Vulnerabilities catalog, and there are no confirmed reports of attacks using it. The vulnerability sits in the kernel's garbage collector for AF_UNIX sockets. That collector cleans up file descriptors passed between processes t...

Attackers are exploiting a critical flaw in F5 BIG-IP Access Policy Manager (APM) that lets them run code on a BIG-IP system without logging in, F5 says. The flaw,  CVE-2026-94127 , affects only systems in which APM serves as an OAuth authorization server, issuing access tokens to applications. F5 disclosed it in  an advisory  on September 22 and has released engineering hotfixes. APM is the BIG-IP module that controls how users reach an organization's applications and networks. The vulnerable setup has an APM access policy and an OAuth authorization server profile on the same virtual server, which hosts the BIG-IP address that receives the OAuth traffic. Specific malicious traffic sent to that virtual server can lead to remote code execution. The flaw is a heap-based buffer overflow. F5 rates it 9.8 out of 10 on CVSS v3.1 and 9.3 on CVSS v4.0. Because the malicious traffic goes to the virtual server itself, limiting access to the BIG-IP management interface does...

A Chinese threat actor codenamed UTA0565 has been observed exploiting the recently disclosed Google Chrome-Microsoft Windows exploit chain as zero-days through fake websites. The attacks, detected on September 3 and 4, 2026, involved the chaining of two vulnerabilities in Chrome (CVE-2026-85046, CVE-2026-87491) and one impacting Windows Advanced Local Procedure Call (CVE-2026-85880) to break out of the browser's sandbox and achieve remote code execution. "UTA0565 masqueraded as various entities including media organizations and a non-governmental organization (NGO)," Volexity researchers Damien Cash and Tom Lancaster said in an analysis published this week. "Notably, this threat actor's campaigns differed from previously documented attacks by using multiple fake websites to deceive victims." One such campaign targeted Asian government entities with Chinese- and English-language phishing emails that urged recipients to support Hong Kong activist Cho...

A new security vulnerability in Next.js could allow attackers to run code on a server via  ImageResponse , the feature that generates Open Graph and other social preview images, Vercel said. The risk applies when an app puts values an attacker controls, such as text read from the request URL, into the image. Vercel, which develops Next.js,  fixed the flaw  on September 22 in version 16.3.6. The flaw, tracked as CVE-2026-94545 , affects Next.js 16.2.0 through 16.3.5 when ImageResponse runs on the Node.js runtime, which Next.js  uses by default . Vercel's  advisory  rates it critical, with a CVSS score of 9.5. The Edge version of ImageResponse is not affected, and neither is Next.js 15. ImageResponse uses  Satori , a Vercel library, to convert the image layout into SVG code before the final PNG is generated. Affected apps are those that "pass attacker-controlled values into SVG content, attributes, or styles during image generation", according to ...

The cyber extortion group known as ShinyHunters on Tuesday claimed it had breached the U.S. Federal Bureau of Investigation and stolen data belonging to current and former employees at the agency. "We have compromised the FBI. We hold very sensitive data on almost ALL FBI Agents and individuals who filed an application with the FBI for a job," the group said in a statement posted on their dark web site. "Whether it be a Special Agent or any other role within your agency. The following FBI services were compromised: Criminal Justice (CJ), HR, Medlink, and more." The development was first reported by 404 Media. ShinyHunters said the FBI was targeted in response to a May 2026 public service announcement (PSA) that detailed the threat actor's targeting of Canvas , an online Learning Management System (LMS), while urging victims not to pay. The attackers, in their own counter PSA, described them as "substantial false allegations," adding, "w...

Attackers exploited a previously unknown flaw in Check Point's Security Management Server in a handful of targeted attacks on July 23,  the company said . The flaw, CVE-2026-93616 , allows an attacker who can access the server's web service to run scripts on it without logging in. Check Point released a fix on September 22 for the server that controls firewall policies for the Check Point gateways it manages. Separately,  Check Point said  attackers have been trying since September 12 to exploit a VPN flaw it  fixed on September 9 . The attempts, against a flaw tracked as CVE-2026-85102, have targeted customers of Spark, Check Point's firewall line for small businesses. When the fix came out, Check Point had no evidence the flaw was being exploited. CVE-2026-93616 is a path traversal bug in the management server's web service. The service does not properly limit which files and folders a request can reach. An attacker can use it to upload scripts to the s...

WordPress has fixed a critical flaw in its core software that lets an attacker with no account make a site load a PHP file from outside its theme folders. On some servers, that can go further, allowing the attacker to run their own code. The fix shipped on September 22 in WordPress 7.1.2, with fixes for every branch the project still supports, back to 4.7, and WordPress is telling site owners to  update now . WordPress rates the flaw as critical, assigns it a CVSS score of 9.2, and assigns it  CVE-2026-87902 . Reaching it requires no account and no action from a logged-in user. Every version from 4.7.0 through 7.1.1 is affected. That includes 7.1.1, from WordPress's  September 17 security release , so a site updated less than a week ago still needs this one. It is a separate flaw from the ones that the release fixed.

Cybersecurity researchers have disclosed details of a malicious npm package named "tw-pkgprobe-7731" that masquerades as a security tool targeting developers integrating Twilio into their applications, while stealthily attempting to harvest sensitive data. The package, named "tw-pkgprobe-7731," was first uploaded to the npm registry in mid-August 2026 by an npm account named "twdepprobe7731." In total, 11 versions of the package were published in quick succession on the same day over an approximately 45-minute time period. The npm user account no longer exists as of writing. "The first version of tw-pkgprobe-7731 posed as an authorized security research probe," ReversingLabs researcher Lucija Valentić said in a report published today. "Comments inside the package describe it as an 'Authorized bug-bounty research probe (Twilio HackerOne program)' that 'runs only inside Twilio's serverless packager sandbox' and ...
