Magnet Goblin Targets Publicly Facing Servers Using 1-Day Vulnerabilities
- Magnet Goblin is a financially motivated threat actor that quickly adopts and leverages 1-day vulnerabilities in public-facing services as an initial infection vector. At least in one case of Ivanti Connect Secure VPN (CVE-2024-21887), the exploit entered the group’s arsenal as fast as within 1 day after a POC for it was published. Campaigns that we were able to attribute to this actor targeted Ivanti, Magento, Qlink Sense and possibly Apache ActiveMQ. Analysis of the actor’s recent Ivanti Connect Secure VPN campaign revealed a novel Linux version of a malware called NerbianRAT, in addition to WARPWIRE, a JavaScript credential stealer. * The actor’s arsenal also includes MiniNerbian, a small Linux backdoor, and remote monitoring and management (RMM) tools for Windows like ScreenConnect and AnyDesk.
