Mozilla on Monday announced a new controls section in its Firefox desktop browser settings that allows users to completely turn off generative artificial intelligence (GenAI) features. "It provides a single place to block current and future generative AI features in Firefox," Ajit Varma, head of Firefox, said . "You can also review and manage individual AI features if you choose to use them. This lets you use Firefox without AI while we continue to build AI features for those who want them." Mozilla first announced its plans to integrate AI into Firefox in November 2025, stating it's fully opt-in and that it's incorporating the technology while placing users in the driver's seat. The new feature is expected to be rolled out with Firefox 148, which is scheduled to be released on February 24, 2026. At the outset, AI controls will allow users to manage the following settings individually - Translations Alt text in PDFs (adding accessibility descrip...

A China-linked threat actor known as Lotus Blossom has been attributed with medium confidence to the recently discovered compromise of the infrastructure hosting Notepad++. The attack enabled the state-sponsored hacking group to deliver a previously undocumented backdoor codenamed Chrysalis to users of the open-source editor, according to new findings from Rapid7. The development comes shortly after Notepad++ maintainer Don Ho said that a compromise at the hosting provider level allowed threat actors to hijack update traffic starting June 2025 and selectively redirect such requests from certain users to malicious servers to serve a tampered update by exploiting insufficient update verification controls that existed in older versions of the utility. The weakness was plugged in December 2025 with the release of version 8.8.9. It has since emerged that the hosting provider for the software was breached to perform targeted traffic redirections until December 2, 2025, when the attac...

A security audit of 2,857 skills on ClawHub has found 341 malicious skills across multiple campaigns, according to new findings from Koi Security, exposing users to new supply chain risks. ClawHub is a marketplace designed to make it easy for OpenClaw users to find and install third-party skills. It's an extension to the OpenClaw project, a self-hosted artificial intelligence (AI) assistant formerly known as both Clawdbot and Moltbot. The analysis, which Koi conducted with the help of an OpenClaw bot named Alex, found that 335 skills use fake pre-requisites to install an Apple macOS stealer named Atomic Stealer (AMOS). This activity set has been codenamed ClawHavoc . "You install what looks like a legitimate skill – maybe solana-wallet-tracker or youtube-summarize-pro," Koi researcher Oren Yomtov said. "The skill's documentation looks professional. But there's a 'Prerequisites' section that says you need to install something first." This...

A high-severity security flaw has been disclosed in OpenClaw (formerly referred to as Clawdbot and Moltbot) that could allow remote code execution (RCE) through a crafted malicious link. The issue, which is tracked as CVE-2026-25253 (CVSS score: 8.8), has been addressed in version 2026.1.29 released on January 30, 2026. It has been described as a token exfiltration vulnerability that leads to full gateway compromise. "The Control UI trusts gatewayUrl from the query string without validation and auto-connects on load, sending the stored gateway token in the WebSocket connect payload," OpenClaw's creator and maintainer Peter Steinberger said in an advisory. "Clicking a crafted link or visiting a malicious site can send the token to an attacker-controlled server. The attacker can then connect to the victim's local gateway, modify config (sandbox, tool policies), and invoke privileged actions, achieving 1-click RCE."

Microsoft has announced a three-phase approach to phase out New Technology LAN Manager (NTLM) as part of its efforts to shift Windows environments toward stronger, Kerberos-based options. The development comes more than two years after the tech giant revealed its plans to deprecate the legacy technology, citing its susceptibility to weaknesses that could facilitate relay attacks and allow bad actors to gain unauthorized access to network resources. NTLM was formally deprecated in June 2024 and no longer receives updates. "NTLM consists of security protocols originally designed to provide authentication, integrity, and confidentiality to users," Mariam Gewida, Technical Program Manager II at Microsoft, explained. "However, as security threats have evolved, so have our standards to meet modern security expectations. Today, NTLM is susceptible to various attacks, including replay and man-in-the-middle attacks, due to its use of weak cryptography." Despite the d...

Every week brings new discoveries, attacks, and defenses that shape the state of cybersecurity. Some threats are stopped quickly, while others go unseen until they cause real damage. Sometimes a single update, exploit, or mistake changes how we think about risk and protection. Every incident shows how defenders adapt — and how fast attackers try to stay ahead. This week’s recap brings you the key moments that matter most, in one place, so you can stay informed and ready for what’s next. ⚡ Threat of the Week Google Disrupts IPIDEA Residential Proxy Network — Google has crippled IPIDEA, a massive residential proxy network consisting of user devices that are being used as the last-mile link in cyberattack chains. According to the tech giant, not only do these networks permit bad actors to conceal their malicious traffic, but they also open up users who enroll their devices to further attacks. Residential IP addresses in the U.S., Canada, and Europe were seen as the most desirable. ...

For mid-market organizations, cybersecurity is a constant balancing act. Proactive, preventative security measures are essential to protect an expanding attack surface. Combined with effective protection that blocks threats, they play a critical role in stopping cyberattacks before damage is done. The challenge is that many security tools add complexity and cost that most mid-market businesses can’t absorb. With limited budgets and lean IT and security teams, organizations often focus on detection and response. While necessary, this places a significant operational burden on teams already stretched thin. A more sustainable approach is security across the complete threat lifecycle—combining prevention, protection, detection, and response in a way that reduces risk without increasing cost or complexity. Why Mid-Market Security Often Feels Stuck Most mid-market organizations rely on a small set of foundational tools, such as endpoint protection, email security, and network firewalls....

The maintainer of Notepad++ has revealed that state-sponsored attackers hijacked the utility's update mechanism to redirect update traffic to malicious servers instead. "The attack involved [an] infrastructure-level compromise that allowed malicious actors to intercept and redirect update traffic destined for notepad-plus-plus.org," developer Don Ho said . "The compromise occurred at the hosting provider level rather than through vulnerabilities in Notepad++ code itself." The exact mechanism through which this was realized is currently being investigated, Ho added. The development comes a little over a month after Notepad++ released version 8.8.9 to address an issue that resulted in traffic from WinGUp, the Notepad++ updater, being "occasionally" redirected to malicious domains, resulting in the download of poisoned executables. Specifically, the problem stemmed from the way the updater verified the integrity and authenticity of the downloaded u...

The update infrastructure for eScan antivirus, a security solution developed by Indian cybersecurity company MicroWorld Technologies, has been compromised by unknown attackers to deliver a persistent downloader to enterprise and consumer systems. "Malicious updates were distributed through eScan's legitimate update infrastructure, resulting in the deployment of multi-stage malware to enterprise and consumer endpoints globally," Morphisec researcher Michael Gorelik said . MicroWorld Technologies has revealed that it detected unauthorized access to its infrastructure and immediately isolated the impacted update servers, which remained offline for over eight hours. It has also released a patch that reverts the changes introduced as part of the malicious update. Impacted organizations are recommended to contact MicroWorld Technologies to obtain the fix. It also pinned the attack as resulting from unauthorized access to one of its regional update server configurations, whi...

Cybersecurity researchers have disclosed details of a supply chain attack targeting the Open VSX Registry in which unidentified threat actors compromised a legitimate developer's resources to push malicious updates to downstream users. "On January 30, 2026, four established Open VSX extensions published by the oorzc author had malicious versions published to Open VSX that embed the GlassWorm malware loader," Socket security researcher Kirill Boychenko said in a Saturday report. "These extensions had previously been presented as legitimate developer utilities (some first published more than two years ago) and collectively accumulated over 22,000 Open VSX downloads prior to the malicious releases." The supply chain security company said that the supply chain attack involved the compromise of the developer's publishing credentials, with the Open VSX security team assessing the incident as involving the use of either a leaked token or other unauthorized ...

A Farsi-speaking threat actor aligned with Iranian state interests is suspected to be behind a new campaign targeting non-governmental organizations and individuals involved in documenting recent human rights abuses. The activity , observed by HarfangLab in January 2026, has been codenamed RedKitten . It's said to coincide with the nationwide unrest in Iran that began towards the end of 2025, protesting soaring inflation, rising food prices, and currency depreciation. The ensuing crackdown has resulted in mass casualties and an internet blackout . "The malware relies on GitHub and Google Drive for configuration and modular payload retrieval, and uses Telegram for command-and-control," the French cybersecurity company said. What makes the campaign noteworthy is the threat actor's likely reliance on large language models (LLMs) to build and orchestrate the necessary tooling. The starting point of the attack is a 7-Zip archive with a Farsi filename that contains...

Google-owned Mandiant on Friday said it identified an "expansion in threat activity" that uses tradecraft consistent with extortion-themed attacks orchestrated by a financially motivated hacking group known as ShinyHunters. The attacks leverage advanced voice phishing (aka vishing) and bogus credential harvesting sites mimicking targeted companies to gain unauthorized access to victim environments by collecting sign-on (SSO) credentials and multi-factor authentication (MFA) codes. The end goal of the attacks is to target cloud-based software-as-a-service (SaaS) applications to siphon sensitive data and internal communications and extort victims. The tech giant's threat intelligence team said it's tracking the activity under multiple clusters, including UNC6661, UNC6671, and UNC6240 (aka ShinyHunters), so as to account for the possibility that these groups could be evolving their modus operandi or mimicking previously observed tactics. "While this methodo...
