  1. Version numbers are usually added automatically. In most cases, the packages listed here were created only to distribute malicious code.

Campaign data

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

Campaign description

Package presents little functionality, but excessive fake 'telemetry' module. This fake telemetry is used to download and run malicious executables. Code is designed to survive different blocks: first, there is an attempt to download the executable from one of five Cloudflare Workers. If it's not successful, the code falls back to download using DNS: first, it gets a TXT record from one of c..dl.well1[.]site domains, depending on the system. This record returns a number, which is then used to iterate over domains in the form <0...n>..dl.well1[.]site and reconstruct the encoded executable from their TXT records. The downloaded binary is then executed and removed afterward. Using a PTH file ensures persistence and runs on every Python start. In this campaign, versions 0.0.1 hold disarmed code (without the necessary configuration), which is completed in further updates.

This is a continuation of the 2026-07-haproxy-config-client campaign.

See more details on the campaign page.

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.

basic_exfiltration

The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

covering-tracks

The package contains code to cover its tracks, e.g. by deleting malicious code after execution.

data-stored-in-dns

Campaign targets data-stored-in-dns.

override_install

The package overrides the install command in setup.py to execute malicious code during installation.

persistence

Campaign targets persistence.

remote_executable

Downloads and executes a remote executable.
