Details

During installation, obfuscated code exfiltrates cryptocurrency wallet data to a hardcoded location and places a backdoor through a new authorized SSH key. Information about the placed backdoor is sent back to the attacker, and sshd configuration is adjusted to ensure the successful remote connection.

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

Campaign: 2026-05-ninja-core-utils

Reasons (based on the campaign):

  • The package overrides the install command in setup.py to execute malicious code during installation.

  • obfuscation

  • crypto-related

  • exfiltration-crypto

  • backdoor
