Is Coco-External.exe safe?
No engines flagged the file and sandbox behaviour shows only benign ambient activity.
Zero detections across 75 engines, no offensive techniques observed, and medium prevalence over four years support a clean classification. The single direct-IP contact lacks host-reputation data but does not override the absence of malicious signals.

Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Zero detections across 75 engines, no offensive techniques observed, and medium prevalence over four years support a clean classification. The single direct-IP contact lacks host-reputation data but does not override the absence of malicious signals.
All 75 reporting engines returned clean results, including 17 tier-1 engines. The unsigned status is neutral for a file with no detections and no brand-mismatch claims. Sandbox execution recorded only ambient techniques and no malicious verdict. Medium prevalence and long history without similar-hash matches further reduce risk. The low-severity heuristic on direct-IP traffic is inconclusive without host reputation.
What We Detected
75 antivirus engines scanned the sample; none returned a malicious or suspicious result. The file is an unsigned 64-bit Windows executable first seen in 2022 with medium prevalence.
Threat Behavior
One sandbox execution recorded eight ambient MITRE techniques and no offensive techniques. No domains were contacted; a single IPv6 address was reached, but host-reputation coverage is unavailable. No dropped children or persistence indicators were observed.
What To Do Now
The file can be considered safe for normal use. Keep endpoint protection enabled and avoid running unsigned executables from untrusted sources as a general precaution.
Where this verdict could be wrong1 caveat
- contactedHosts is null — host-reputation cross-check was not completed, so the single IPv6 contact cannot be confirmed clean or 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.
- Zero malicious detections across 75 reporting engines
- No offensive MITRE techniques observed
- Medium prevalence with long clean history
The file shows no malicious indicators and can be treated as safe; continue running current endpoint protection.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
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
This file appears low risk based on the evidence available now.
- Recovery step 01
Run it only when it came from the developer's official site or another source you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
