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 no malicious detections across 69 reporting engines, with 16 tier-1 vendors (BitDefender, Kaspersky, ESET-NOD32, Fortinet, GData, Emsisoft, F-Secure, Avira, AVG, DrWeb, Avast, Ikarus, and others) all silent. The filename and 76.7 MB size match the official Ryujinx emulator distribution. A prior sample with the same imphash was verdicted safe (score 88). The triggered heuristic on direct-IP contact is a false positive: the IP 162.159.36.2 belongs to Cloudflare's anycast network, and legitimate software routinely uses DoH or direct CDN endpoints. The file's prevalence across 362 unique submitters in 10 days indicates widespread legitimate distribution. No external-intelligence hits, no malicious sandbox verdicts, and no malicious dropped children further support a clean classification.

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. tier1Malicious=0; 16 tier-1 engines (Avast, BitDefender, Kaspersky, ESET-NOD32, Fortinet, GData, Emsisoft, F-Secure, Avira, AVG, DrWeb, Ikarus) all silent or undetected

  2. Ryujinx is a legitimate open-source Nintendo Switch emulator (GitHub: Ryujinx/Ryujinx); filename and 76.7 MB size match official distribution

  3. similarHashes: imphash 759a3c183e9207f0571ae8ae7b2a52e0 previously verdicted 'safe' (score 88, ai:low_trust_engines_only) on same filename

  4. Contacted IP 162.159.36.2 is Cloudflare anycast (162.159.0.0/16); legitimate for DoH/CDN, not C2 indicator

  5. prevalence: common_new (362 submitters, 401 submissions in 10 days); high volume indicates widespread legitimate distribution

Points in its favour
  • 16 tier-1 antivirus engines all silent or undetected
  • Legitimate open-source project (Ryujinx Nintendo Switch emulator)
  • High prevalence: 362 unique submitters, 401 submissions in 10 days
  • Prior imphash verdict: safe (score 88)
  • No external-intelligence malicious hits (CIRCL, YARAify, MalwareBazaar)
What to do

    Sample contacted 1 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

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.
