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.

Reasoning

The file exhibits a clean profile across all detection layers. Tier-1 antivirus engines (17 vendors) unanimously report the file undetected, with zero malicious detections across tier-2 and low-trust engines as well. The JSON format and filename ('350 robux nebula fflag- json') are consistent with benign gaming-related data. No runtime behaviour data, dropped children, or malicious host contact was observed. External intelligence sources (CIRCL, MalwareBazaar, YARAify) returned no hits. The file is unsigned but shows no brand mismatch or adversarial filename patterns. Low submission volume (1 source) is offset by the unanimous clean verdict from our antivirus network.

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.

  2. engines.malicious=0/61 reporting; zero detections across all tiers (tier1, tier2, low_trust)

  3. File type JSON (6471 bytes); filename analysis flags all false; no installer, security software, or research-tool indicators

  4. signing.verified=false, unsigned; no signer history; no brand mismatch detected

  5. behaviour=null, droppedChildren=null, contactedHosts=null, externalIntel all negative (CIRCL, MalwareBazaar, YARAify hits=false)

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.
