Source: kam193 (1cefe6c8a9ac6ede7c6ba497cf17011bf431812980749bb0068995ebba4039d9)

If the method from the module is called, it attempts to download a malicious code (identified as msf payload) and save it locally. In the analysed version, the code starting the malicious code was commented out.

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

Campaign: 2025-07-web3dummycti

Reasons (based on the campaign):

  • The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.

  • action-hidden-in-lib-usage

  • Downloads and executes a remote malicious script.
