Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Six of 71 engines flagged the file, including one tier-1 engine naming a generic trojan label. The sample is unsigned, showed no malicious sandbox behaviour, and has one prior suspicious verdict on the same imphash. Mixed signals place the file in the suspicious category.
The engine distribution shows limited consensus: only one tier-1 engine contributed a malicious result and the family label is non-specific. Absence of code signing removes a common trust anchor, yet the single sandbox run produced no offensive MITRE techniques or malicious verdict. The prior imphash match returned suspicious, but signer mismatch prevents strong weight. Direct-IP traffic triggered a heuristic, yet host reputation data is unavailable. Overall evidence supports a borderline classification rather than a definitive malicious or safe call.
What We Detected
TrendMicro-HouseCall (tier1) and five additional engines reported malicious indicators on the 7.8 MB Win32 executable. No code signature is present. Sandbox execution wrote ten temporary files and contacted eight IP addresses without domain names, but produced no malicious verdict or offensive techniques.
Threat Behavior
Observed behaviour is consistent with both legitimate self-extracting utilities and potential droppers. The high-entropy overlay and direct-IP connections are inconclusive without host reputation results. No dropped child files have been previously classified malicious.
What To Do Now
Do not execute the file on production systems. Submit it to additional sandboxes or the antivirus analysis for broader coverage. Keep endpoint protection enabled and avoid disabling security software.
Where this verdict could be wrong3 caveats
- Single tier-1 detection with generic family label and no tier1FamilyConsensus.strong may represent heuristic false positive rather than confirmed malware.
- Unsigned status could reflect legitimate PyInstaller or self-extracting tools rather than deliberate evasion.
- contactedHosts=null means no complete host-reputation result is available; direct-IP traffic alone is inconclusive.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No malicious sandbox verdict
- No malicious dropped children
- Medium prevalence across 58 sources
- Unsigned executable
- Single tier-1 malicious detection
- Direct-IP network traffic without domain resolution
Treat the file as untrusted pending further multi-engine or sandbox corroboration; maintain all security software in an active state.
Behavior
Plain-English impact first, then the observed runtime evidence.
What this file does
Observed actions and their security significance
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Moderate concern: Decoded or unpacked concealed content while running.
Moderate concern: Checked the environment for virtualisation or analysis tools.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.
What this file did when executed
This file was detonated in 1 sandbox and its runtime behaviour was observed.
Adversary techniques mapped to the MITRE ATT&CK framework.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

What to do now
We couldn't fully clear this file. Treat it with caution.
Don't run it unless you're certain it came from a source you trust.
Check where you got it — an unexpected attachment or a random download link is a red flag.
If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Get a fresh copy from the developer's official site or an official app store.
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
