Aikido Security discovered a coordinated campaign of at least 15 malicious JetBrains Marketplace plugins (installed ~70,000 times) that steal AI API keys from users by exfiltrating credentials to a hardcoded HTTP endpoint (http://39.107.60.51/api/software/key); researchers and BleepingComputer confirmed the behavior and the plugins remain available as of the report.
