MAL-2026-17881 Malicious code in py-sock2 (PyPI)

Importing py-sock2's agentaix module downloads a mutable Python file from https://raw.githubusercontent.com/anonrider404/pypl/refs/heads/main/readme.txt to a temporary .py file and launches it without a visible console on Windows. Its agentaix console entry point imports the module. The remote file's Git history contains a Windows remote file management client that registers persistence through an HKCU Run entry, polls https://googleforum.pythonanywhere.com for commands, and supports file upload, download, deletion, and command execution. An earlier remote-file revision is byte-identical to the readme.txt payload reported in MAL-2026-17752 (agentaix); the 39,931-byte agentaix/gui.py is also byte-identical across that package and py-sock2. The remote file is mutable; its contents at the time of any particular victim import and actual execution on victim systems have not been established.

The package installs a persistent job that allows the attacker for exfiltrating files and executing remote code on the victim's machine.

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

Campaign: 2026-10-agentaix

Reasons (based on the campaign):

• files-exfiltration

• peristence-autorun

• The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

• rat

• persistence

• Downloads and executes a remote malicious script.
