Verdict Safe
Is SDL2.
No antivirus engine flagged this widely observed DLL, and the isolated sandbox mapping lacks a target, corroboration, or malicious runtime verdict.

Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 67 antivirus engines that checked it flagged the DLL, and it has been submitted 650 times by 423 sources since 2020. One sandbox mapped possible process injection, but named no target, recorded no injected process, and returned a clean result; the complete host check also found no cached malicious or suspicious hosts.
The strongest evidence is the absence of detections across 74 engines, including no major flags. The file is also well established, with 650 submissions from 423 sources dating back to 2020. A completed sandbox run produced a mapping, but no injected process or target was recorded, and the sandbox verdict was clean. All 12 distinct observed hosts were covered by the reputation check, with no malicious or suspicious cache matches; three reverse-DNS lookups were identified as sandbox background traffic. The four YARA matches are generic capability or compiler-oriented rules rather than malware-specific signatures. Although the DLL is unsigned, that limitation does not outweigh the broad, longstanding, and mutually consistent evidence.
What We Detected
None of the 67 antivirus engines that checked it flagged the DLL, including the participating major antivirus engines. The same hash has appeared in 650 submissions from 423 sources since December 2020, which is consistent with established commodity software rather than a rare, newly introduced payload.
Threat Behavior
One completed sandbox run mapped possible process injection under MITRE T1055, but it did not identify an injected process, target, or exact injection method, and the run returned a clean verdict. The observed host list was fully covered by the reputation check: none of the 12 distinct domains and IP addresses matched cached malicious or suspicious hosts. Three reverse-DNS lookups were attributed to sandbox background traffic rather than the sample. Four community YARA rules matched, but all were generic and none was malware-specific; the PE also showed no packing or high-entropy code.
What To Do Now
The file can remain in place when it came with software obtained from a trusted source. Because it is unsigned, verify its origin or compare its SHA-256 with the supplying application's official package if provenance is uncertain, and keep security software enabled.
Where this verdict could be wrong3 caveats
- The DLL is unsigned, so publisher identity cannot be authenticated through a code-signing certificate.
- One sandbox mapped activity to process injection, although it identified no injected process or target and returned a clean verdict.
- Ten generated files lack saved child verdicts, leaving their individual reputations unconfirmed.
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 67 antivirus engines that checked it flagged the file.
- The hash has 650 submissions from 423 sources and has been known since December 2020.
- The completed sandbox run returned a clean result and recorded no injected target process.
- All 12 observed hosts were checked, with no cached malicious or suspicious matches.
- No packer, high-entropy code, or malware-specific YARA rule was found.
- The DLL has no digital signature, so its publisher cannot be authenticated.
- A sandbox mapped possible process injection, but did not identify the method or target.
- Ten generated files have no saved individual verdicts.
