Details
-= Per source details. Do not edit below this line.=-
Source: kam193 (dc4606b3e3f05632a889906f4c259e329a08308382fbc27329752eb8ea6a6c3c)
The package imitates colorama, and places a proxy object over the original colorama module that on every usage executes a remote code. The remote script installs a backdoor through legitimate tunnelling software and upload access credentials to the attacker.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2025-05-coloraiz
Reasons (based on the campaign):
-
impersonation
-
clones-real-package
-
action-hidden-in-lib-usage
-

-
Downloads and executes a remote malicious script.
