Code is designed to survive different blocks: first, there is an attempt to download the executable from one of five Cloudflare Workers. If it\u0027s 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 \u003c0...n\u003e.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: 2026-06-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",
