ThreatsDay Bulletin: Worm Code Leaked, AI Agent Phished, Claude Action Patch + 28 New Stories

Jun 11, 2026 Hacking News / Cybersecurity News
It's been one of those weeks. You expect the usual noise: recycled malware, sloppy attacks, another easy target getting hit. Instead, there's a supply chain attack kit in a public repo, a $5,000-a-month RAT that clones browsers, and research showing AI agents can be tricked into leaking real credentials. The bigger problem is how polished this all looks now. Mule networks run like SaaS. Deepfake KYC bypass is sold as a feature. Endpoint tools can be quietly weakened using built-in OS settings, with no exploit needed. Here's the full list of threats, tools, flaws, and updates worth knowing.
GitHub to Disable npm Install Scripts by Default to Stop Supply Chain Attacks

GitHub to Disable npm Install Scripts by Default to Stop Supply Chain Attacks

Jun 11, 2026 Developer Security / Software Supply Chain
GitHub has announced what it said are "breaking changes" coming to npm version 12, one of which turns off install scripts by default to combat software supply chain threats. The changes aim to combat attack techniques that abuse the "npm install" command to trigger the execution of malicious code using npm lifecycle hooks. "Npm install" is used to download and install all the necessary dependencies for a Node.js project. Version 12 is scheduled for release next month. Describing install-time lifecycle scripts as the "single largest code-execution surface in the npm ecosystem," GitHub said the "npm install" command runs scripts from every transitive dependency, as a result of which a single compromised package anywhere in the dependency tree can run arbitrary code on a developer machine or CI runner. By blocking such behaviours, the idea is to require explicit user approval before code execution is initiated automatically durin...
China-Linked JDY Botnet Expands to 1,500+ Devices for Cyber Reconnaissance

China-Linked JDY Botnet Expands to 1,500+ Devices for Cyber Reconnaissance

Jun 10, 2026 Botnet / Network Security
Cybersecurity researchers have warned of a "resurgence and expansion" of JDY , a covert network associated with China-nexus state-sponsored threat actors. "The JDY botnet comprises over 1,500 SOHO [small office and home office] and IoT devices and operates as a centrally controlled, high-performance scanner used to discover, fingerprint, and continuously map exposed services at scale," Lumen's Black Lotus Labs said in a report shared with The Hacker News. JDY was first flagged as a cluster within another botnet codenamed KV-botnet in mid-December 2023. Primarily used for broader scanning against internet targets, the stealthy network comprising compromised SOHO routers, firewalls, and IoT devices has been put to use by Chinese hacking groups like Volt Typhoon. Following KV-botnet's takedown by the U.S. government in early 2024, the botnet operators began making behavioral changes to the network, with the second KV cluster largely going offline. It...

Microsoft Restores Some GitHub Repos, Keeps Others Offline as Miasma Probe Continues

Microsoft Restores Some GitHub Repos, Keeps Others Offline as Miasma Probe Continues

Jun 09, 2026 AI Security / Software Supply Chain
Microsoft on Monday confirmed that it temporarily removed some GitHub repositories in response to a recent security incident that led to 73 of its open-source projects being compromised to inject an information stealer into the code. "Our priority is to protect customers and the broader ecosystem," a Microsoft spokesperson told The Hacker News via email. "We temporarily removed some repositories as we investigated potential malicious content. Some of these repos have been restored after review, while others may remain offline while work continues." "As part of our investigation, we notified a small number of customers who may have pulled down content from the affected repositories. We will continue to investigate, and if anything further is identified that requires customer action, we will reach out directly through our established support channels." The development comes days after the Windows maker cut off access to dozens of its open-source proj...
WinRAR Flaw Exploited by Russia-Aligned Groups to Deploy Stealers in Ukraine

WinRAR Flaw Exploited by Russia-Aligned Groups to Deploy Stealers in Ukraine

Jun 09, 2026 Vulnerability / Cyber Espionage
Two Russia-aligned cyber attack campaigns have continued to exploit a security flaw in WinRAR to target Ukrainian organisations, almost a year after patches for the vulnerability were released. The activity has been attributed by Trend Micro to Earth Dahu (aka Gamaredon) and SHADOW-EARTH-066 (aka UAC-0226). It involves the exploitation of CVE-2025-8088 , a path traversal flaw that allows an attacker to write files outside the extraction directory via NTFS Alternate Data Streams (ADS). It was patched by WinRAR in July 2025. The findings show "how unmanaged software keeps an exploited entry point open long after the fix ships," Trend Micro researchers Hiroyuki Kakara and Feike Hacquebord said in an analysis published Monday. The WinRAR exploit chain exploited by SHADOW-EARTH-066 is a departure from Excel macro droppers previously used by the threat actor to deliver an information stealer called GIFTEDCROOK. The latest iteration makes use of crafted RAR archives featur...
