Summary
Malicious code in lyroxpy (PyPI)
Details
-= Per source details. Do not edit below this line.=-
Source: kam193 (a9016ac99840c4d68028c7b724382974154c9bf75b410da9c6b4a75ff6d20b1f)
The package contains an embedded archive with an executable. When importing the module, the embedded archive is run as a module. Code inside extracts the executable and saves it to a temporary file. Further the code keeps an open file handler and removes the original file, effectively making the impression the file no longer exists. Using the file handler the executable (which is either a native Python module or was created from Python code) is run. Further behavior is not known.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2026-02-lyroxpy
Reasons (based on the campaign):
-
obfuscation
-
covering-tracks
