Why we think so
2 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
All 66 antivirus engines that checked it returned clean results with no major detections. Sandbox analysis produced no malicious verdict and no malicious files it created were dropped. Medium prevalence and portable filename pattern align with a legitimate system utility.
Zero malicious engine detections across a broad reporting base combined with a clean sandbox verdict outweigh the two rule-based rules that fired on process injection and direct-IP contact. The file shows medium prevalence from over 2000 sources and matches the portable utility pattern. Unsigned status is typical for this class of tool. No external intelligence or dropped malicious files it created contradict the clean profile.
What We Detected
67 of the 66 antivirus engines that checked it scanned the ZIP archive; none flagged it malicious or suspicious. Sandbox execution observed process creation and direct-IP network activity but returned no malicious verdict. Ten files it created were inspected with zero malicious outcomes.
Threat Behavior
Rule-based rules noted T1055 process injection and direct-IP a control server patterns. These behaviours can appear in both legitimate diagnostic tools and malware; the sandbox did not classify the activity as malicious and no external control-server domains or known-bad hosts were contacted.
What To Do Now
Verify the download source matches the official CrystalDiskInfo project. Scan the extracted files with up-to-date local AV before execution. Monitor for any unexpected outbound connections after launch.
Where this verdict could be wrong1 caveat
- Unsigned status removes any trusted-publisher safety net, leaving the file reliant on prevalence and sandbox signals alone.
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 engine detections across 74 scanners
- Clean sandbox verdict and no malicious files it created
- Medium prevalence from 2033 unique sources
- Executable inside archive
- Direct-IP network contacts without DNS resolution
