Fake Claude AI Website Distributes New Beagle Windows Backdoor Malware

A fake version of the Claude AI website distributes a malicious download labeled "Claude-Pro Relay," which installs a previously undocumented Windows backdoor named Beagle. The campaign targets users seeking the legitimate Claude AI service by mimicking its official site. No specific dates, victim counts, or technical indicators (e.g., hashes, CVE IDs) were disclosed in the report. The malware functions as a backdoor, though its exact capabilities or persistence mechanisms were not detailed. The attack leverages social engineering by exploiting trust in AI-related software. The threat was documented by BleepingComputer.
