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.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-07-haproxy-config-client\n\n\nReasons (based on the campaign):\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n\n\n - Downloads and executes a remote executable.\n\n\n - obfuscation\n\n\n - dependency-confusion\n\n\n - other\n\n\n - malware\n\n\n - covering-tracks\n\n\n - targetted-attack\n\n\n - data-stored-in-dns\n\n\n## Affected packages\n\n- `ipa-user-collector`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
