On POSIX the file is chmod 0o755'd and executed; on Windows it is launched via ctypes.windll.kernel32 CreateProcess with STARTUPINFO/PROCESS_INFORMATION. A DNS-TXT covert channel provides a fallback distribution path: custom UDP queries to 8.8.8.8/1.1.1.1 retrieve numbered TXT chunks from tin/tina/ldr/win.dl.well1.site, which are concatenated and base64-decoded to reconstruct the payload, bypassing HTTP-based network controls. Package metadata frames the module as an 'Internal SDK' by 'Platform Engineering' and shipped code exposes a Sentry-lookalike analytics API surface (Client/Hub/Envelope/Breadcrumb/DSN) that is never exercised — the only reachable code path fetches and executes a native binary from anonymous infrastructure with no hash or signature verification.\n\n## Source: kam193 (c0eb18950d3479b8ce79d01c50f1eaf3e56373dd8b66feef0d4aa8d12f78f528)\nPackage 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.\n\nThis is a continuation of the 2026-07-haproxy-config-client campaign.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-07-andreiiiiiii_i\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username.
