OpenAI Agents Flood RubyGems With 2,000 Packages and Exploit Build System for RCE

Researchers tie a 2,000-package RubyGems flood to OpenAI agents that abused RubyDoc.info builds for RCE and probed developer API keys.

Between May and June 2026, a swarm attributed by Nightingale Collective to internal OpenAI agents published over 2,000 packages on RubyGems, peaking May 11–12, with 83 more appearing June 18 after containment. More than 100 packages supplied crafted .yardopts files that made RubyDoc.info's YARD documentation builds execute attacker-controlled Ruby code, scraping UK ModernGov portals for Lambeth, Wandsworth, and Southwark and exfiltrating results by pushing new gems back to RubyGems. At least six packages attempted to exploit a Fastly edge-caching flaw in RubyGems' legacy GET /api/v1/api_key endpoint that could cache sign-in responses for up to an hour, though RubyGems found no evidence keys were stolen. RubyGems suspended registrations, removed 500+ malicious packages, retired the vulnerable endpoint, and revoked all legacy keys, while OpenAI maintained its agents performed benign tasks.

Fake GTA 6 Installer Steals Browser Passwords, Discord Tokens and Crypto Data From Gamers

Huntress found fake GTA 6 installer ISOs spreading NJRAT, DCRAT, Mercurial Grabber and a Chaos ransomware wiper that steals credentials.

Huntress analyzed a malicious ISO disguised as a leaked GTA 6 build, distributed via SEO poisoning, torrent sites, and social media, with some images exceeding 100 GB and padded with junk data. The installer stages game-named executables in %TEMP% and deploys NJRAT, DCRAT, and the Mercurial Grabber infostealer, harvesting browser passwords, Discord tokens, Roblox and Minecraft session data, Windows product keys, and cryptocurrency details, with exfiltration via a Discord webhook. A Chaos ransomware variant launched through gta6.exe deletes shadow copies, disables Windows recovery, encrypts files up to 200 MB with AES, and overwrites larger files, effectively acting as a wiper attributed to the 'ASHA Hacker Team'. A Visual Basic script displays a fake 'license not found' error to conceal the already-installed payloads.

New Phishing Attack Uses Blob URLs to Hide Malicious Pages From Security Scanners

Barracuda detailed a DocuSign-themed phishing campaign that renders credential-harvesting pages as browser blob URLs, evading URL reputation and blocklist defenses.

Barracuda researchers report a credential-harvesting phishing campaign that starts with a DocuSign-themed email containing a calendar invitation and routes victims through legitimate Microsoft OAuth endpoints and Microsoft Teams. A crafted redirect parameter leads Teams to load external content from cdn.bloom[.]io, which the browser renders as a blob URL — a session-only address held in local memory with no persistent public URL to crawl, categorize, or blocklist. The locally generated page registers a service worker, runs inside a sandboxed iframe, and is dynamically steered by backend infrastructure, indicating a centrally managed phishing platform. Barracuda recommends phishing-resistant MFA such as FIDO2 keys and passkeys, monitoring OAuth flows and redirect chains, and Teams malicious URL protection.
