presents itself as a Minecraft SMP donation and rank-promotion helper. The published 0.1.0 sdist instead executes an encrypted downloader before setuptools processes the package. The automated package report identified a critical signal at : downloaded or embedded bytes are decrypted and passed to with unrestricted builtins. Review of the cited path confirms the install trigger. When runs during build or installation, lines 6-7 import and call before runs. hardcodes . The loader skips obvious staging environments and hosts without a normal user profile, accepts a directive returned by that endpoint, and otherwise falls back to the encrypted blob shipped in . Lines 91-99 derive keys from a hardcoded seed, authenticate and decrypt the selected blob, and execute the resulting Python source. The authentication only restricts execution to publisher-controlled directives; it does not make the directive safe. Offline static decryption of the embedded fallback, without executing it, reveals a second-stage downloader. It checks Windows BIOS strings for VMware, VirtualBox, QEMU, Xen and other virtualisation products; searches the process list for Wireshark, Procmon, Process Hacker, IDA, x64dbg and other analysis tools; calls ; creates a one-time marker; and sleeps for a random interval. If those checks pass, it downloads , treats compressed data hidden inside PNG chunks as a ZIP archive, extracts it, and starts the included as a detached, hidden background process. The automated sandbox completed without observing the second-stage request; the source explicitly avoids staged environments and hosts without a normal user profile. The cited static path and the decrypted fallback establish the install-time chain independently. Evidence: calls the loader during build/install; sets the manifest endpoint; lines 62-99 select, authenticate, decrypt and execute the directive; contains the encrypted fallback. --- _-= Per source details.

How to fix MAL-2026-17196

What to do

Three questions, each answered from this record only. Confirm the vendor advisory before you patch.

Should you patch?

Exploitation likelihood is not on this record for MAL-2026-17196. A missing EPSS score is not a low risk. Compare Malicious code in donutpromotion with the linked advisory before you change production.

Which versions are affected?

Compare what you have installed with 0.1.0. Compare the installed version with the linked vendor advisory before you change production.

What should an analyst verify?

No weakness class is stored. EPSS is not on this record yet. There is no CISA KEV listing. No Exploit-DB or Metasploit reference is linked. Use the source links for the original advisory.
