tinkoff-cloud-apis-internal @8.5.4

Summary

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. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-07-andreiiiiiii_i Reasons (based on the campaign): - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk. - The package overrides the install command in setup.py to execute malicious code during installation. - Downloads and executes a remote executable. - covering-tracks - persistence - abuses-pth - data-stored-in-dns
