The disguised script registers the installer as with https://googleforum.pythonanywhere.com and then polls that endpoint for commands. The command handlers include (arbitrary shell via ), plus list, download, upload, delete, rename, and open — a full remote-controlled shell and file manager driven by a hardcoded author endpoint, with no authentication beyond the username@hostname identifier. The handler reads any path accessible to the user process, base64-encodes the contents, and POSTs them back to https://googleforum.pythonanywhere.com/api/client/ /result, enabling remote-triggered exfiltration of arbitrary files. For persistence, writes an value under HKCU\Software\Microsoft\Windows\CurrentVersion\Run pointing at pythonw.exe plus the renamed script so the C2 client auto-starts at every user login. The payload fires the moment the module is imported, with no user interaction, and the readme.txt disguise plus hidden-window launch are deliberate evasion of casual inspection. ## Source: kam193 (f91699ff915dd2020b9736052f7036ee723aaaa0628e5384ff47f65577d397f6) The package installs a persistent job that allows the attacker for exfiltrating files and executing remote code on the victim's machine. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-10-agentaix Reasons (based on the campaign): - files-exfiltration - peristence-autorun - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine. - rat - persistence - Downloads and executes a remote malicious script.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

MAL-2026-17755 is a unknown public vulnerability record for this product. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether this product is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: agent-vx (0.1.0). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: no CVSS/EPSS yet. It is not currently listed in the CISA Known Exploited catalog. Sources contributing to this record: osv. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.

Exploitation and remediation

  • Exploitation evidence

    Not listed as known exploited in CISA KEV. Not in the CISA KEV catalog.

  • Patch and remediation

    No required-action text is stored yet. Use the vendor or CERT links in Sources for patch availability.

  • Safe detection guidance

    Compare installed versions with the affected ranges below and verify the advisory from the original publisher. This site stores metadata and outbound links only; it does not ship exploit code or proof-of-concept payloads.
