Malicious code in haproxy-config-client (PyPI)
-= Per source details. Do not edit below this line.=-
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.
