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.
Two tier-1 engines flag the file as malicious while fifteen tier-1 engines remain silent. The binary is unsigned, newly observed, and exhibits one offensive MITRE technique (T1560).
The combination of two tier-1 detections and an offensive technique outweighs the clean majority and lack of sandbox confirmation. Unsigned status and rare_new prevalence keep the file out of the safe category. No strong family consensus or external-intel corroboration prevents a malicious verdict.
What We Detected
10 of 74 engines flagged the sample; Microsoft and Symantec (tier-1) returned Trojan and ML.Attribute labels. The file is a 21 MB unsigned 64-bit PE first seen three days ago.
Threat Behavior
Sandbox execution recorded T1560 (data encrypted for impact) among 15 ambient techniques. No malicious dropped children or sandbox verdict were produced. No domains or IPs were contacted during the single sandbox run.
What To Do Now
Do not execute the file on production systems. Keep endpoint protection enabled and submit the sample to additional sandboxes for deeper behavioural analysis.
Where this verdict could be wrong3 caveats
- Only 2 tier-1 engines flagged the file; the remaining 15 tier-1 engines returned clean, and no strong family consensus exists.
- Sandbox produced no malicious verdict and no malicious dropped children were observed.
- No contacted domains or IPs were recorded, so network-behaviour evidence is absent rather than malicious.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Majority of tier-1 engines clean
- No malicious dropped children
- No external-intel hits
- Unsigned executable
- Rare and recently observed
- Two tier-1 malicious detections
- Offensive MITRE technique T1560
Treat the file as untrusted; avoid execution until further sandbox or dynamic analysis is available.
Behavior
Plain-English impact first, then the observed runtime evidence.
What this file does
Observed actions and their security significance
High concern: Used an input-capture technique that can record credentials or keystrokes.
High concern: Manipulated how the operating system loads code, which can redirect execution.
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: Scans through your files and folders.
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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. 10 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.

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.
