MT AI Engine · our arbiter

The verdict, reasoned out.

Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.

82%Confidence
High
Reasoning

The file is a small (9.5 KB) Java JAR archive with embedded HTML/JavaScript, identified as a Minecraft mod variant (Fapcraft). No antivirus engine flags it as malicious; tier-1 vendors unanimously report clean or undetected status. The sandbox behaviour shows Java process execution and system service restart attempts (cups service), which are typical of legitimate installers or mods, not malware command-and-control or persistence mechanisms. The four dropped children are unverdicted but not flagged as malicious. No external intelligence (CIRCL, MalwareBazaar, YARAify) corroborates a threat. The file is unsigned and rare (1 submission), but the absence of detections across such a broad and high-trust engine set strongly indicates benign intent.

Key signals · 5

Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

  1. tier1ReportedClean=16 (Avast, BitDefender, Kaspersky, Microsoft, ESET-NOD32, Fortinet, Emsisoft, F-Secure, GData, Avira, AVG, DrWeb) — all major vendors report clean or undetected.

  2. engines.malicious=0/61 reporting; tier1Malicious=0 — zero high-trust detections across 75 total engines.

  3. behaviour.offensiveTechniques=[T1543.002] in context of Java process execution and cups service restart — consistent with legitimate installer/mod, not malware C2.

  4. droppedChildren.hasMaliciousChild=false; all 4 dropped hashes verdict=null — no confirmed malicious payload extraction.

  5. prevalence.classification=rare_new; externalIntel all negative (CIRCL, MalwareBazaar, YARAify) — no researcher corroboration of threat.

Points in its favour
  • Zero malicious detections across 75 antivirus engines.
  • 16 tier-1 vendors (Microsoft, Kaspersky, BitDefender, ESET-NOD32, Fortinet, Emsisoft, F-Secure, GData, Avira, AVG, DrWeb, Avast) report clean or undetected.
  • No external intelligence corroboration (CIRCL, MalwareBazaar, YARAify all negative).
  • No malicious dropped children; no malicious network contact.
  • System process activity consistent with legitimate Java application or mod installer.

Files are processed in a streaming pass-through — MalwareTips never stores the binary on its servers. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
