Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
Safe to use if obtained from the official OpenSSL distribution channel. Keep your antivirus enabled and verify the download source.
Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.
No scanner can promise a file is 100% safe.

Chapter 02
Why we think so
1 point against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
It was submitted by 156 distinct sources, and the combined sandbox verdict was clean. It is unsigned, so confirm it was downloaded from the official project.
No engine flagged the file, including the 18 major antivirus engines. It is widely submitted, first seen on Sep 29, 2026. The sandbox runs show a typical Inno Setup self-extraction with Explorer cache writes. The credential and injection mappings have no named target or credential-store access, so they carry no weight. Contacted hosts are the analysis VM's own background traffic. The lack of a signature is the only soft point.
What We Detected
0 of the 70 antivirus engines that checked it flagged the file, and no public database lists it as malware.
Threat Behavior
The combined sandbox verdict was clean. The installer unpacked temporary files and showed no injection target, persistence or malicious host contact. Some credential-related technique mappings were recorded without any supporting artefact.
What To Do Now
Download OpenSSL only from the official project or a trusted distributor and keep your security software enabled.
Where this verdict could be wrong2 caveats
- The file is unsigned, so there is no publisher signature to confirm it is the official OpenSSL installer build.
- Two files built with the same import table were earlier rated suspicious and unknown, but those matches reflect the shared Inno Setup framework and are weak.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 70 antivirus engines that checked it flagged the file
- Submitted by 156 distinct sources
- Combined sandbox verdict was clean with no injection target
- No listings in public malware databases
- The file is unsigned, so its publisher cannot be verified from a signature.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
EvidenceT1055 (sandbox MITRE mapping)VirusTotal's sandbox summary maps this run to MITRE T1003 (OS Credential Dumping), but no process targeting LSASS or another credential store was recorded. VirusTotal maps T1003 on clean files more often than on detected ones, so the mapping alone is not evidence of credential theft.
