Iran-Linked Hackers Use Fake LinkedIn Job Offers to Deploy NodeRabbit and PollCat RATs

Iran-linked Mirage Kitten targets software engineers with fake LinkedIn recruiter coding tests deploying new NodeRabbit and PollCat RATs.

Kaspersky researchers link the campaign to Mirage Kitten (also tracked as UNC1549, Smoke Sandstorm, Nimbus Manticore), with victims in aviation, aerospace and fintech in Egypt, Ethiopia and Afghanistan. Trojanized npm dependencies (colorized_terminal, pretty-log) bundled in coding-challenge archives launch the Node.js implants across Windows, Linux and macOS. NodeRabbit uses AES-256-GCM-encrypted C2 via Azure, and its third variant persists through a fake GitHub Copilot Helper VS Code extension plus Git post-merge/post-checkout hooks. PollCat is an obfuscated JavaScript RAT that registers with C2 before OTP authentication and inventories tools from 24 security vendors.

Iran-linked APT Mirage Kitten Uses Fake Job Tests to Spread Malware

Kaspersky reports Iran-linked Mirage Kitten delivers new NodeRabbit and PollCat malware to fintech and aviation targets via fake LinkedIn coding assessments.

Kaspersky researchers documented two previously undocumented Node.js malware families, NodeRabbit and PollCat, attributed with high confidence to Iran-linked APT group Mirage Kitten. The malware is delivered via fake recruiter personas on LinkedIn offering coding assessments hosted on Amazon S3, with instructions banning AI assistants so AI code-review tools would not flag the trojanized npm packages. NodeRabbit is cross-platform (Windows, Linux, macOS), uses AES-256-GCM-encrypted C2 on Azure, includes sandbox checks, and one variant installs a fake 'GitHub Copilot Helper' VS Code extension plus Git hook persistence. Victims identified so far are in fintech and aviation organizations across Egypt, Ethiopia, and Afghanistan.

Iranian Hackers Pose as Recruiters to Deliver Cross

Kaspersky attributes new cross-platform RATs NodeRabbit and PollCat to Iranian group Nimbus Manticore, spread via recruiter-themed LinkedIn lures.

Kaspersky links two previously undocumented malware families, NodeRabbit (Node.js) and PollCat (obfuscated JavaScript), to the Iranian threat actor Nimbus Manticore, also known as Iranian Dream Job. Victims in Afghanistan, Egypt, and Ethiopia received trojanized coding challenge archives containing fake npm packages (colorized_terminal, pretty-log) that silently launched the RATs as background processes. NodeRabbit contacts Azure-hosted C2 servers via checkin, task, and result API endpoints and supports 11 commands including shell execution, file operations, and network enumeration. Persistence is platform-specific: Windows Run keys or scheduled tasks, Linux cron entries, and macOS launch agents, impersonating Microsoft Edge updates or Intel's Driver & Support Assistant.

DDoS Attacks Cause Major Threema Outages

Sustained distributed denial-of-service attacks knocked Swiss secure messenger Threema offline for hours before upstream filtering restored service; On-Prem users unaffected.

Threema suffered a series of large-scale DDoS attacks that left its Swiss secure messaging service unavailable for about four hours Tuesday evening, with intermittent outages into Wednesday morning until restoration at 12:23 p.m. CEST. Attacks also targeted colocation partner Nine and kept changing patterns, complicating mitigation. Threema deployed additional upstream DDoS protection on August 14 and plans status page improvements; Threema On-Prem customers running their own infrastructure were unaffected.

China-Linked Jewelbug Uses XG-Web for Government Espionage and Crypto Fraud

China-linked Jewelbug runs government espionage and crypto fraud from a single XG-Web browser-based control framework.

Broadcom's Symantec and Carbon Black detail Jewelbug, a China-based hackers-for-hire group conducting espionage against governments and militaries in the Middle East, Southeast Asia, and South Asia, plus crypto fraud against Chinese-speaking victims. Operations center on XG-Web, a browser-centric remote-access and infostealing framework, with implants spanning browsers, Windows, Linux, and network devices. The group overlaps with CL-STA-0049, Ink Dragon, Earth Alux, and REF7707, and compromised a Middle Eastern government's webmail across 15 tenants.
