Two Google Chrome extensions have turned malicious after what appears to be a case of ownership transfer , offering attackers a way to push malware to downstream customers, inject arbitrary code, and harvest sensitive data. The extensions in question, both originally associated with a developer named "akshayanuonline@gmail.com" (BuildMelon), are listed below - QuickLens - Search Screen with Google Lens (ID: kdenlnncndfnhkognokgfpabgkgehodd) - 7,000 users ShotBird - Scrolling Screenshots, Tweet Images & Editor (ID: gengfhhkjekmlejbhmmopegofnoifnjp) - 800 users While QuickLens is no longer available for download from the Chrome Web Store, ShotBird remains accessible as of writing. ShotBird was originally launched in November 2024, with its developer, Akshay Anu S (@AkshayAnuOnline), claiming on X that the extension is suitable for "creating professional, studio-like visuals," and that all processing happens locally. According to research published by mo...

Cybersecurity researchers have disclosed a now-patched security flaw in LangChain's LangSmith platform that could be exploited to capture sensitive data, including API keys and user prompts. The vulnerability, which carries a CVSS score of 8.8 out of a maximum of 10.0, has been codenamed AgentSmith by Noma Security. LangSmith is an observability and evaluation platform that allows users to develop, test, and monitor large language model (LLM) applications, including those built using LangChain. The service also offers what's called a LangChain Hub , which acts as a repository for all publicly listed prompts, agents, and models. "This newly identified vulnerability exploited unsuspecting users who adopt an agent containing a pre-configured malicious proxy server uploaded to 'Prompt Hub,'" researchers Sasi Levi and Gal Moyal said in a report shared with The Hacker News. "Once adopted, the malicious proxy discreetly intercepted all user communicatio...

DALL-E for coders? That’s the promise behind vibe coding, a term describing the use of natural language to create software. While this ushers in a new era of AI-generated code, it introduces "silent killer" vulnerabilities: exploitable flaws that evade traditional security tools despite perfect test performance. A detailed analysis of secure vibe coding practices is available here . TL;DR: Secure Vibe Coding Vibe coding, using natural language to generate software with AI, is revolutionizing development in 2025. But while it accelerates prototyping and democratizes coding, it also introduces “silent killer” vulnerabilities: exploitable flaws that pass tests but evade traditional security tools. This article explores: Real-world examples of AI-generated code in production Shocking stats: 40% higher secret exposure in AI-assisted repos Why LLMs omit security unless explicitly prompted Secure prompting techniques and tool comparisons (GPT-4, Claude, Cursor, etc.) Reg...

Cybersecurity researchers have disclosed what they say is an active "Shai-Hulud-like" supply chain worm campaign that has leveraged a cluster of at least 19 malicious npm packages to enable credential harvesting and cryptocurrency key theft. The campaign has been codenamed SANDWORM_MODE by supply chain security company Socket. As with prior Shai-Hulud attack waves , the malicious code embedded into the packages comes with capabilities to siphon system information, access tokens, environment secrets, and API keys from developer environments and automatically propagate by abusing stolen npm and GitHub identities to extend its reach. "The sample retains Shai-Hulud hallmarks and adds GitHub API exfiltration with DNS fallback, hook-based persistence, SSH propagation fallback, MCP server injection with embedded prompt injection targeting AI coding assistants, and LLM API Key harvesting," the company said . The packages, published to npm by two npm publisher aliases,...

Cybersecurity researchers have flagged a "coordinated malware campaign" on the JetBrains Marketplace that has published no less than 15 malicious plugins capable of exfiltrating artificial intelligence (AI) provider keys. "Every plugin poses as an AI coding assistant built on DeepSeek and other large language models, offering chat, commit messages, code review, bug finding, and unit tests," Aikido Security researcher Ilyas Makari said . "They function exactly as advertised. However, the AI provider API key you enter gets exfiltrated to a server controlled by the attacker." The activity is said to have been ongoing since the end of October 2025, with new plugins released as recently as June 10, 2026. Two of the plugins, CodeGPT AI Assistant and DeepSeek AI Assist, have more than 25,000 downloads each, although it's not clear if the counts are authentic or if they have been inflated to fake their popularity. The complete list of plugins is below -...

Cybersecurity researchers have disclosed that artificial intelligence (AI) assistants that support web browsing or URL fetching capabilities can be turned into stealthy command-and-control (C2) relays, a technique that could allow attackers to blend into legitimate enterprise communications and evade detection. The attack method, which has been demonstrated against Microsoft Copilot and xAI Grok, has been codenamed AI as a C2 proxy by Check Point. It leverages "anonymous web access combined with browsing and summarization prompts," the cybersecurity company said. "The same mechanism can also enable AI-assisted malware operations, including generating reconnaissance workflows, scripting attacker actions, and dynamically deciding 'what to do next' during an intrusion." The development signals yet another consequential evolution in how threat actors could abuse AI systems, not just to scale or accelerate different phases of the cyber attack cycle, but als...

Attackers aren’t waiting for patches anymore — they are breaking in before defenses are ready. Trusted security tools are being hijacked to deliver malware. Even after a breach is detected and patched, some attackers stay hidden. This week’s events show a hard truth: it’s not enough to react after an attack. You have to assume that any system you trust today could fail tomorrow. In a world where AI tools can be used against you and ransomware hits faster than ever, real protection means planning for things to go wrong — and still staying in control. Check out this week’s update to find important threat news, helpful webinars, useful tools, and tips you can start using right away. ⚡ Threat of the Week Windows 0-Day Exploited for Ransomware Attacks — A security affecting the Windows Common Log File System (CLFS) was exploited as a zero-day in ransomware attacks aimed at a small number of targets, Microsoft revealed.

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can become an entry point if it’s left unpatched or overlooked. Here’s a clear look at the week’s biggest risks, from exploited network flaws to new global campaigns and fast-moving vulnerabilities. ⚡ Threat of the Week Flaws in Multiple Network Security Products Come Under Attack — Over the past week, Fortinet , SonicWall , Cisco , and WatchGuard said vulnerabilities in their products have been exploited by threat actors in real-world attacks. Cisco said attacks exploiting CVE-2025-20393, a critical flaw in AsyncOS, have been abused by a China-nexus advanced persistent threat (APT) actor cod...

A dataset used to train large language models (LLMs) has been found to contain nearly 12,000 live secrets, which allow for successful authentication. The findings once again highlight how hard-coded credentials pose a severe security risk to users and organizations alike, not to mention compounding the problem when LLMs end up suggesting insecure coding practices to their users. Truffle Security said it downloaded a December 2024 archive from Common Crawl , which maintains a free, open repository of web crawl data. The massive dataset contains over 250 billion pages spanning 18 years.  The archive specifically contains 400TB of compressed web data, 90,000 WARC files (Web ARChive format), and data from 47.5 million hosts across 38.3 million registered domains. The company's analysis found that there are 219 different secret types in the Common Crawl archive, including Amazon Web Services (AWS) root keys, Slack webhooks, and Mailchimp API keys. "'Live' secrets ar...

Rough Monday. Somebody poisoned a trusted download again, somebody else turned cloud servers into public housing, and a few crews are still getting into boxes with bugs that should’ve died years ago — the same old holes, same lazy access paths, same “how the hell is this still open” feeling. One report this week basically reads like a guy tripped over root access by accident and decided to stay there. The weird part is how normal this all sounds now. Fake updates. Quiet backdoors. Remote tools are used like skeleton keys. Forum rats swapping stolen access while defenders burn another weekend chasing logs and praying the weird traffic is just monitoring noise. The Internet’s held together with duct tape and bad sleep. Anyway, Monday recap time. Same fire. New smoke. ⚡ Threat of the Week Ivanti EPMM and Palo Alto Networks PAN-OS Flaws Under Attack —Ivanti warned customers that attackers have successfully weaponized CVE-2026-6973, an improper input validation defect in Endpoint Man...
