Campaign data

Campaign information may not always be 100% accurate for every related package.

Campaign description

In this campaign, the main package (webreader) has an embeded pickle disguised as a config. A related dependency (pafer) contains code to load the pickle. During unpickling, malicious code embeded in the pickle file is automatically executed. It then establishes persistence via a PTH file and downloads the next stage payload. It finally acts like a RAT, allowing remote exfiltration and code execution.

See more details on the campaign page.

RAT

Malicious activity is typical for Remote Access Trojans (RATs).

abuses-pth

The package uses .pth files, sitecustomize or usercustomize modules to execute malicious code during Python startup, even without importing the package code manually.

files_exfiltration

Campaign targets files_exfiltration.

obfuscation

Code uses obfuscation techniques to hide its true purpose.

persistence

Campaign targets persistence.

remote_commands

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

remote_script

Downloads and executes a remote malicious script.

through_dependency

The malicious code is intentionally included in a dependency of the package
