--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (8206a6d3278ef99ffe6f33a695ca3dd6b4ed9856912d79f3066a375d95bcd509) On import of marocolor, a daemon thread recursively walks the user's home directory and uploads every file matching extensions.txt,.pdf,.docx,.jpg,.png,.key,.env,.config, and.sql to a hardcoded Telegram bot endpoint at api.telegram.org/sendDocument (bot id 8534701940, chat id 1785091570) via requests.post with the file attached as a multipart document. The targeted extensions include canonical secret-bearing files (.env,.key,.config,.sql) which commonly hold API keys, database credentials, and private keys. The attacker's Telegram bot token and chat id are embedded in core.py. A second import-time daemon thread executes a fork-bomb-style payload (a function that spawns new threads of itself in an unbounded loop while opening local sockets), exhausting resources on the installer's host. There is no advertised backup, telemetry, or sync functionality that would justify this behavior, and no consent prompt or opt-out. ## Source: kam193 (38b0fa2ee77af46ad9daf78c024a0f599fd0798eef7605cb3eed50d8db65fa22) Package is intended for stealing files to a hardcoded location and performing a DoS on the victim's machine. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-10-marocolor Reasons (based on the campaign): - files-exfiltration - uses-telegram-bot - destructive-actions

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-2026-17900 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: marocolor (1.0.0). 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, pypa. 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 CISA KEV or VulnCheck KEV.

  • 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.
