Why we think so
2 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Zero of the 71 antivirus engines that checked it flagged the file. It is a 17-year-old NSIS installer for DiskInternals ZIP Repair that has been submitted by 1 293 sources and shows no malicious sandbox verdict or dropped malicious files it created.
The complete absence of detections across major and smaller engines, combined with the file’s age and prevalence, outweighs the two sandbox rules that themselves note the observed behaviour is also consistent with legitimate installers. No external-intel corroboration exists and no children or contacted hosts were flagged malicious. The unsigned status is typical for older NSIS packages and does not override the clean multi-engine record.
What We Detected
75-engine scan returned zero malicious or suspicious labels. The sample is an NSIS-packaged Win32 executable first submitted in 2008 and still widely distributed.
Threat Behavior
Sandbox execution recorded MITRE techniques T1055 and T1547.001 plus direct-IP connections, but no malicious verdict was issued and no malicious files it created were dropped. Community comments reference the legitimate DiskInternals domain and product pages.
What To Do Now
The file matches a known commodity utility; keep security software enabled and download only from the vendor site if reinstallation is required.
Where this verdict could be wrong1 caveat
- Unsigned NSIS installer with direct-IP traffic and MITRE T1055/observed; contactedHosts cross-check not completed so no complete contacted-host reputation result was available.
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 detections across 75 engines
- Common_old prevalence with 1 293 submitters since 2008
- No malicious sandbox verdict or files it created
- Unsigned executable
