Reasoning

Kaspersky's explicit detection of 'VHO:Trojan.Win32.Convagent.gen' is a named-family signal from a high-trust tier-1 engine, supported by Symantec's high-confidence flag. The file exhibits offensive MITRE techniques (T1134.004 process injection, T1562.001 defense impairment) typical of remote-access trojans. The filename 'hvnc-client.exe' semantically matches HVNC (Hidden VNC) malware patterns. However, tier-1 consensus is weak (1 engine, not ≥3), and 65 of 70 engines remain silent. No sandbox execution, C2 contact, or dropped-child evidence is present. The sample is unsigned, rare, and newly submitted, limiting corroboration. The combination of tier-1 family naming, offensive techniques, and filename semantics outweighs the weak consensus and absence of runtime confirmation, but confidence remains moderate due to these gaps.

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. Kaspersky (tier-1) flagged 'VHO:Trojan.Win32.Convagent.gen' — named family detection from high-trust engine

  2. Symantec (tier-1) flagged 'ML.Attribute.HighConfidence' — tier-1 confidence signal, though generic label

  3. Offensive MITRE techniques T1134.004 (Process Injection) + T1562.001 (Impair Defenses) — consistent with remote-access trojan behaviour

  4. Filename 'hvnc-client.exe' + 'trojan.convagent' threat label — semantically aligned with HVNC malware family

  5. Unsigned, rare_new (1 submission, 0 days), no signer history, no external intel corroboration — limits confidence but does not contradict malicious signals

Points in its favour
  • No sandbox malicious verdict (no runtime execution observed)
  • No malicious contacted hosts or C2 beaconing detected
  • No dropped children or persistence indicators
  • 65 of 70 engines undetected or silent
Points against
  • Tier-1 engine (Kaspersky) named Convagent trojan family
  • Process injection (T1134.004) and defense-evasion (T1562.001) techniques detected
  • Filename 'hvnc-client.exe' matches HVNC malware semantics
  • Unsigned executable with no signer history
  • Rare, newly submitted sample (0 days old, 1 submission)
What to do

Treat this file as malicious and avoid execution. If encountered in your environment, isolate the affected system and conduct forensic analysis for signs of remote-access activity or defense evasion. Monitor for similar samples with matching imphash or signer patterns.

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.
