Why we think so
3 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Six of the 71 antivirus engines that checked it flag this file, but only with generic labels tied to its packer or machine-learning scores, and no engine names a malware family. Six sandbox runs showed no high-risk behaviour, and the file has circulated widely since 2017. It is a dual-use networking tool, so use it only if you need it.
Only one major antivirus engine flags the file, and Ikarus's label names a commercial packer rather than malware, while 17 other major antivirus engines report nothing. The remaining detections are generic machine-learning or rule labels with no family. Six sandbox runs recorded no injection, no high-risk techniques and no malicious verdict, and the hosts contacted were checked and are not known to be bad. The file has been seen by 148 sources since 2017 and has no listings in malware sample databases or malware-specific rule hits. Packed, unsigned utilities like this commonly attract generic detections.
What We Detected
6 of the 71 antivirus engines that checked it flagged this unsigned executable. Ikarus labels it as a potentially unwanted file because of its Themida-style protector, SentinelOne reports a static AI suspicion, and four less reliable engines give generic machine-learning results. No engine names a malware family. The file is wrapped with a BoxedApp virtualization packer.
Threat Behavior
Six sandbox runs showed no injection into other processes and no high-risk techniques, and the only recorded sandbox verdict was clean. Network contacts were limited to IP ranges that look like Microsoft or CDN infrastructure, and none of the checked hosts are known to be malicious. The file has been widely seen since 2017.
What To Do Now
If you intend to use a netcat GUI, this file shows no evidence of a malware payload. Netcat can open remote shells, so run it only for your own legitimate networking tasks, prefer an official source, and keep your antivirus enabled.
Where this verdict could be wrong3 caveats
- The file is unsigned and wrapped in a BoxedApp/Themida-style packer, which hides its contents from static inspection.
- One community comment reports a third-party sandbox score of 56/100 for evasion behaviour, and batch-feed tags list several malware families, though none of these are corroborated by the engines.
- Netcat itself is a dual-use networking tool that can be misused for remote shells.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Seen by 148 independent sources since 2017.
- Six sandbox runs found no high-risk behaviour and no malicious verdict.
- No engine names a malware family, and 17 major antivirus engines report it clean.
- It has no listings in malware sample databases and no malware-specific rule hits.
- The file is unsigned and wrapped in a commercial packer.
- Netcat is a dual-use networking tool that can be misused.
- One major antivirus engine labels it as potentially unwanted because of the packer.
