Fake Gemini installer delivers Vidar infostealer via Google Colab lure
Attackers used a fake Google Gemini installer hosted on Google Colab to deliver a Go-compiled Vidar infostealer that stole browser credentials from an EMEA company.
Darktrace investigated an EMEA company infection where the top search result for a Gemini-related filename pointed to a Google Colab page that redirected to a fake 'Windows Software Hub' hosting a malicious executable. The ZIP contained a README instructing victims to run the file as administrator and add it to antivirus exceptions, delivering a newer Go-compiled Vidar variant that used dtm[.]kijangturbo88[.]top over Telegram-based infrastructure. The malware stole browser credentials and other sensitive data; Darktrace's Autonomous Response blocked the C2 and quarantined the device.
Hackers Target Claude, Cursor and Codex AI Agents to Steal Tokens and Prompt Histories
Gen Digital found infostealers like Amatera and Remus stealing AI coding agent tokens, prompt histories, and MCP configs from infected Windows and macOS machines.
Gen Digital analysts observed Amatera and Remus detections among tens of thousands of protected Windows users over three months, with Amatera targeting Cline and Continue data and Remus targeting Claude, Cursor, and OpenCode. CallbackBeaver added Cursor and Claude to its collection scope with more than 5,000 samples in 30 days, while macOS-focused Djinn Stealer has been associated with Claude, Codex, Gemini, Cline, OpenCode, and Kilo. The stealers harvest access and refresh tokens, prompt histories, and MCP configuration files that can expose source control, ticketing, databases, cloud resources, and sensitive project context for follow-on fraud. Many stealers add targets via remotely managed rules, meaning this is an adaptation of existing infostealers rather than a new vulnerability in the AI tools themselves.
New Android malware encrypts files, steals data, and harasses victims
Zimperium details Mantax Otax, an Android malware combining ransomware, spyware, and harassment, spread via phishing APKs to Indonesian users.
Zimperium researchers report Mantax Otax is distributed through malicious APKs hosted outside Google Play via phishing and social engineering, then abuses Accessibility permissions for broad device control. It encrypts files with a C2-provided AES key on Android 9 and older, adds '.enc' extensions, and hosts ransom chats on Firebase; researchers exposed attacker chats via a Firebase misconfiguration. The malware steals lock-screen PINs, SMS one-time codes, contacts, WhatsApp and Telegram chats, and captures screens via MediaProjection, while version 2 adds jumpscare overlays and text-to-speech harassment. Google Play Protect already detects and blocks it on up-to-date devices via the App Defense Alliance.
