Campaign data

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

Campaign description

Packages hide a gated execution of a remote code or send over local files. The code masks itself as a legitimate tool, e.g. python2 command, and requires knowing a password to get remote code for execution. Some versions suggest the intention is a tool for cheating on tests, but it could also be used to mask malicious actions.

See more details on the campaign page.
