Malicious package

Published to PyPI · OSV MAL-2026-6749

What to do

Remove ipa-user-collector from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: kam193 (2df148f70b40274f48d5bc4d8ea5a97bb434a743cf7a5c1b271a5a5cd7fa3907) During installation the obfuscated code downloads a malicious executable from a remote location. 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 c.lin.dl.wel1[.]ru. This record returns a number, which is then used to iterate over domains in the form <0...n>.lin.dl.wel1[.]r and reconstruct the encoded executable from their TXT records. The executable is finally saved under a partially random name, executed, and removed after execution. The Linux executable contacts a few domains, but there is no more detailed information about its behavior available. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-07-haproxy-config-client Reasons (based on the campaign): - The package overrides the install command in setup.py to execute malicious code during installation. - Downloads and executes a remote executable. - obfuscation - dependency-confusion - other - malware - covering-tracks - targetted-attack - data-stored-in-dns

Impact

Installation of ipa-user-collector version 8.5.3 results in execution of a remote malicious Linux executable on the host system. This can lead to compromise of the affected system, potential data exfiltration, or further malware deployment. The malicious code uses multiple fallback mechanisms to ensure delivery and execution, increasing the likelihood of successful infection. The exact impact beyond execution and network communication is not detailed.

Defensive guidance

Users should avoid installing this package version from PyPI. Verify package integrity and source before installation. Consider using trusted package repositories and implement supply chain security measures such as package signing and verification. Monitor for updates from the package maintainers or PyPI security advisories for any official fixes or removals.

Summary

The ipa-user-collector PyPI package version 8.5.3 contains obfuscated malicious code embedded in its setup.py install command. During installation, it downloads a Linux executable from one of several Cloudflare Workers or, failing that, reconstructs it from DNS TXT records across multiple domains. The executable is saved with a partially randomized filename, executed, and then deleted. The Linux payload contacts multiple domains, though its detailed functionality is unknown. The package is part of a malicious campaign involving dependency confusion and attempts to evade detection by obfuscation and covering tracks.
