Summary
Malicious code in textwrap-formatter (PyPI)
Details

-= Per source details. Do not edit below this line.=-

Source: kam193 (18da24e92fd40457ad3df2af568c07d41b35f44e6e07e8fac3bf0eafba9c2154)

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
