File verdict·Decided by the MT AI Engine
Our call

Safe

Zero engine detections, verified Realtek signature, medium prevalence, and clean sandbox behaviour outweigh the single direct-IP heuristic.

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

Zero malicious detections from 74 engines including 17 tier-1 engines eliminates the possibility of a named family or tier-1 consensus. The verified Realtek signature and medium prevalence (74 sources) indicate a distributed legitimate component. The single triggered heuristic on direct-IP contact is a weak signal without sandbox or engine backing. No dropped children, no malicious hosts, and no YARA/CIRCL hits further support a benign 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. engines: 0 malicious across 70 reporting engines, tier1Malicious=0

  2. signing.verified=true, signer='Realtek Semiconductor Corp.'

  3. prevalence.classification='medium' (74 unique sources, 82 submissions)

Points in its favour
  • 0/74 engines flagged malicious
  • Verified signature by Realtek Semiconductor Corp.
  • Medium prevalence across 74 sources
  • No sandbox malicious verdict
  • No external intelligence hits
Points against
  • Direct-IP contact without DNS resolution (162.159.36.2)
What to do

Proceed with normal use; the evidence shows a clean, signed Realtek component with only an isolated heuristic flag.

  • DirectIpC2medium

    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.
