Source: kam193 (6a77aad2f42165ec9582f04fffab948f6a1125564e34f4d09c8d089b2708d8d2)

While described as educational package to simulate post-exploitation environment, the malware is active and once started, automatically attempts to exfiltrate sensitive data (credentials, cookies, etc.) and places a Discord implant. The remote target is hard coded in the code.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2025-06-mainx

Reasons (based on the campaign):

  • obfuscation

  • infostealer

  • files-exfiltration

  • exfiltration-credentials

  • exfiltration-browser-data

  • peristence-autorun

  • The package contains code to detect if it is running in a sandbox environment.
