## Overview


---
_-= Per source details. Do not edit below this line.=-_

## Source: kam193 (30caca1d5e67322644a0eb6cf8098151d975415baab826d14a0bba75117ae95e)
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


## Affected packages

- `tinkoff-cloud-apis-internal`

## Remediation

Refer to the advisory for the patched release.
