Microsoft on Tuesday rolled out its first security update for 2026 , addressing 114 security flaws, including one vulnerability that it said has been actively exploited in the wild. Of the 114 flaws, eight are rated Critical, and 106 are rated Important in severity. As many as 58 vulnerabilities have been classified as privilege escalation, followed by 22 information disclosure, 21 remote code execution, and five spoofing flaws. According to data collected by Fortra, the update marks the third-largest January Patch Tuesday after January 2025 and January 2022. These patches are in addition to two security flaws that Microsoft has addressed in its Edge browser since the release of the December 2025 Patch Tuesday update, including a spoofing flaw in its Android app ( CVE-2025-65046 , 3.1) and a case of insufficient policy enforcement in Chromium's WebView tag ( CVE-2026-0628 , CVSS score: 8.8). The vulnerability that has come under in-the-wild exploitation is CVE-2026-20805 (CV...

Node.js has released updates to fix what it described as a critical security issue impacting "virtually every production Node.js app" that, if successfully exploited, could trigger a denial-of-service (DoS) condition. "Node.js/V8 makes a best-effort attempt to recover from stack space exhaustion with a catchable error, which frameworks have come to rely on for service availability," Node.js's Matteo Collina and Joyee Cheung said in a Tuesday bulletin. "A bug that only reproduces when async_hooks are used would break this attempt, causing Node.js to exit with 7 directly without throwing a catchable error when recursions in user code exhaust the stack space. This makes applications whose recursion depth is controlled by unsanitized input vulnerable to denial-of-service attacks." At its core, the shortcoming stems from the fact that Node.js exits with code 7 (denoting an Internal Exception Handler Run-Time Failure ) instead of gracefully handling the...

The Computer Emergency Response Team of Ukraine (CERT-UA) has disclosed details of new cyber attacks targeting its defense forces with malware known as PLUGGYAPE between October and December 2025. The activity has been attributed with medium confidence to a Russian hacking group tracked as Void Blizzard (aka Laundry Bear or UAC-0190). The threat actor is believed to be active since at least April 2024. Attack chains distributing the malware leverage instant messaging Signal and WhatsApp as vectors, with the threat actors masquerading as charity organizations to convince targets into clicking on a seemingly-harmless link ("harthulp-ua[.]com" or "solidarity-help[.]org") impersonating the foundation and download a password-protected archive.

Cybersecurity researchers have discovered a major web skimming campaign that has been active since January 2022, targeting several major payment networks like American Express, Diners Club, Discover, JCB Co., Ltd., Mastercard, and UnionPay. "Enterprise organizations that are clients of these payment providers are the most likely to be impacted," Silent Push said in a report published today. Digital skimming attacks refer to a category of client-side attacks in which bad actors compromise legitimate e-commerce sites and payment portals to inject malicious JavaScript code that's capable of stealthily harvesting credit card information and other personal information when unsuspecting users attempt to make a payment on checkout pages. These attacks are classified under an umbrella term called Magecart , which initially referred to a coalition of cybercriminal groups that targeted e-commerce sites using the Magento software, before diversifying to other products and platf...

Cybersecurity researchers have disclosed details of a malicious Google Chrome extension that's capable of stealing API keys associated with MEXC, a centralized cryptocurrency exchange (CEX) available in over 170 countries , while masquerading as a tool to automate trading on the platform. The extension, named MEXC API Automator (ID: pppdfgkfdemgfknfnhpkibbkabhghhfh), has 29 downloads and is still available on the Chrome Web Store as of writing. It was first published on September 1, 2025, by a developer named "jorjortan142." "The extension programmatically creates new MEXC API keys, enables withdrawal permissions, hides that permission in the user interface (UI), and exfiltrates the resulting API key and secret to a hardcoded Telegram bot controlled by the threat actor," Socket security researcher Kirill Boychenko said in an analysis. According to the Chrome Web Store listing, the web browser add-on is described as an extension that "simplifies connecti...

AI agents are no longer just writing code. They are executing it. Tools like Copilot, Claude Code, and Codex can now build, test, and deploy software end-to-end in minutes. That speed is reshaping engineering—but it's also creating a security gap most teams don't see until something breaks. Behind every agentic workflow sits a layer few organizations are actively securing: Machine Control Protocols (MCPs) . These systems quietly decide what an AI agent can run, which tools it can call, which APIs it can access, and what infrastructure it can touch. Once that control plane is compromised or misconfigured, the agent doesn't just make mistakes—it acts with authority. Ask the teams impacted by CVE-2025-6514 . One flaw turned a trusted OAuth proxy used by more than 500,000 developers into a remote code execution path. No exotic exploit chain. No noisy breach. Just automation doing exactly what it was allowed to do—at scale. That incident made one thing clear: if an AI agent can execute...

Cybersecurity researchers have disclosed details of a previously undocumented and feature-rich malware framework codenamed VoidLink that's specifically designed for long-term, stealthy access to Linux-based cloud environments According to a new report from Check Point Research, the cloud-native Linux malware framework comprises an array of custom loaders, implants, rootkits, and modular plugins that enable its operators to augment or change its capabilities over time, as well as pivot when objectives change. It was first discovered in December 2025. "The framework includes multiple cloud-focused capabilities and modules, and is engineered to operate reliably in cloud and container environments over extended periods," the cybersecurity company said in an analysis published today. "VoidLink's architecture is extremely flexible and highly modular, centered around a custom Plugin API that appears to be inspired by Cobalt Strike's Beacon Object Files (BOF) appr...

Old Playbook, New Scale: While defenders are chasing trends, attackers are optimizing the basics The security industry loves talking about "new" threats. AI-powered attacks. Quantum-resistant encryption. Zero-trust architectures. But looking around, it seems like the most effective attacks in 2025 are pretty much the same as they were in 2015. Attackers are exploiting the same entry points that worked - they're just doing it better. Supply Chain: Still Cascading Downstream As the Shai Hulud NPM campaign showed us, supply chain remains a major issue. A single compromised package can cascade through an entire dependency tree, affecting thousands of downstream projects. The attack vector hasn't changed. What's changed is how efficiently attackers can identify and exploit opportunities. AI has collapsed the barrier to entry. Just as AI has enabled one-person software projects to build sophisticated applications, the same is true in cybercrime. What used to requi...

ServiceNow has disclosed details of a now-patched critical security flaw impacting its ServiceNow artificial intelligence (AI) Platform that could enable an unauthenticated user to impersonate another user and perform arbitrary actions as that user. The vulnerability, tracked as CVE-2025-12420 , carries a CVSS score of 9.3 out of 10.0. It has been codenamed BodySnatcher by AppOmni. "This issue [...] could enable an unauthenticated user to impersonate another user and perform the operations that the impersonated user is entitled to perform," the company said in an advisory released Monday. The shortcoming was addressed by ServiceNow on October 30, 2025, by deploying a security update to the majority of hosted instances, with the company also sharing the patches with ServiceNow partners and self-hosted customers. The following versions include a fix for CVE-2025-12420 - Now Assist AI Agents (sn_aia) - 5.1.18 or later and 5.2.19 or later Virtual Agent API (sn_va_as_ser...

Cybersecurity researchers have disclosed details of a new campaign dubbed SHADOW#REACTOR that employs an evasive multi-stage attack chain to deliver a commercially available remote administration tool called Remcos RAT and establish persistent, covert remote access. "The infection chain follows a tightly orchestrated execution path: an obfuscated VBS launcher executed via wscript.exe invokes a PowerShell downloader, which retrieves fragmented, text-based payloads from a remote host," Securonix researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a technical report shared with The Hacker News. "These fragments are reconstructed into encoded loaders, decoded in memory by a .NET Reactor–protected assembly, and used to fetch and apply a remote Remcos configuration. The final stage leverages MSBuild.exe as a living-off-the-land binary (LOLBin) to complete execution, after which the Remcos RAT backdoor is fully deployed and takes control of the comprom...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has warned of active exploitation of a high-severity security flaw impacting Gogs by adding it to its Known Exploited Vulnerabilities ( KEV ) catalog. The vulnerability, tracked as CVE-2025-8110 (CVSS score: 8.7), relates to a case of path traversal in the repository file editor that could result in code execution. "Gogs Path Traversal Vulnerability: Gogs contains a path traversal vulnerability affecting improper Symbolic link handling in the PutContents API that could allow for code execution," CISA said in an advisory. Details of the shortcoming came to light last month when Wiz said it discovered it being exploited in zero-day attacks. The vulnerability essentially bypasses protections put in place for CVE-2024-55947 to achieve code execution by creating a git repository, committing a symbolic link pointing to a sensitive target, and using the PutContents API to write data to the symlink. This, in t...

Threat actors have been observed uploading a set of eight packages on the npm registry that masqueraded as integrations targeting the n8n workflow automation platform to steal developers' OAuth credentials. One such package, named "n8n-nodes-hfgjf-irtuinvcm-lasdqewriit," mimics a Google Ads integration, and prompts users to link their advertising account in a seemingly legitimate form and then siphon OAuth credentials to servers under the attackers' control. "The attack represents a new escalation in supply chain threats," Endor Labs said in a report published last week. "Unlike traditional npm malware, which often targets developer credentials, this campaign exploited workflow automation platforms that act as centralized credential vaults – holding OAuth tokens, API keys, and sensitive credentials for dozens of integrated services like Google Ads, Stripe, and Salesforce in a single location." The complete list of identified packages, which ...

This week made one thing clear: small oversights can spiral fast. Tools meant to save time and reduce friction turned into easy entry points once basic safeguards were ignored. Attackers didn't need novel tricks. They used what was already exposed and moved in without resistance. Scale amplified the damage. A single weak configuration rippled out to millions. A repeatable flaw worked again and again. Phishing crept into apps people rely on daily, while malware blended into routine system behavior. Different victims, same playbook: look normal, move quickly, spread before alarms go off. For defenders, the pressure keeps rising. Vulnerabilities are exploited almost as soon as they surface. Claims and counterclaims appear before the facts settle. Criminal groups adapt faster each cycle. The stories that follow show where things failed—and why those failures matter going forward. ⚡ Threat of the Week Maximum Severity Security Flaw Disclosed in n8n — A maximum-severity vulnerability ...

A new wave of GoBruteforcer attacks has targeted databases of cryptocurrency and blockchain projects to co-opt them into a botnet that's capable of brute-forcing user passwords for services such as FTP, MySQL, PostgreSQL, and phpMyAdmin on Linux servers. "The current wave of campaigns is driven by two factors: the mass reuse of AI-generated server deployment examples that propagate common usernames and weak defaults, and the persistence of legacy web stacks such as XAMPP that expose FTP and admin interfaces with minimal hardening," Check Point Research said in an analysis published last week. GoBruteforcer, also called GoBrut, was first documented by Palo Alto Networks Unit 42 in March 2023, documenting its ability to target Unix-like platforms running x86, x64, and ARM architectures to deploy an Internet Relay Chat (IRC) bot and a web shell for remote access, along with fetching a brute-force module to scan for vulnerable systems and expand the botnet's reach. ...
