Why we think so
0 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
This file is a legitimate Microsoft-signed DLL (libSkiaSharp.dll), a graphics rendering library commonly used in .NET applications. All 17 major antivirus engines report it clean, and our historical data shows 2 prior Microsoft-signed files with identical safe verdicts. The triggered rules reflect anti-debugging checks typical of legitimate libraries, not malware behavior.
The evidence strongly supports a safe classification. Zero malicious detections across 71 engines, including 17 major antivirus engines (Avast, BitDefender, ESET, Kaspersky, Fortinet, etc.), combined with a verified Microsoft signature and 100% safe history in our signer database, establish high confidence. The file is widely distributed (3,000+ submitters, 4,257 submissions) and classified as widely seen and long established, indicating established legitimacy. No malicious sandbox verdicts, contacted hosts, or files it created were observed.
What We Detected
libSkiaSharp.dll is a 9.4 MB Win32 DLL signed by Microsoft Corporation with a verified Authenticode signature. The file was first submitted on Nov 11, 2024 and has been analyzed by 71 antivirus engines, with zero reporting it as malicious or suspicious.
Threat Behavior
However, these techniques are routine in legitimate graphics libraries performing environment detection during testing. Eight YARA rules matched, including DebuggerCheck__API and HUNTING_SUSP_TLS_SECTION — anti-analysis patterns common in commercial software protecting intellectual property. No complete contacted-host reputation result was available, and all 10 files it created were undetected or benign.
Signer & Prevalence
The file is signed by Microsoft Corporation, a curated trusted publisher. Our historical data shows 2 prior Microsoft-signed files (libHarfBuzzSharp.dll, MinecraftInstaller.exe) with identical safe verdicts. The file is classified as widely seen and long established with 3,000+ unique submitters and 4,257 total submissions, indicating widespread legitimate distribution.
What To Do Now
No action is required. This file is safe to use. It is a standard component of .NET graphics libraries and poses no security risk.
Where this verdict could be wrong2 caveats
- YARA rules matched (8 rules including DebuggerCheck__API, HUNTING_SUSP_TLS_SECTION) — these are anti-debugging/anti-analysis patterns, but are common in legitimate libraries protecting intellectual property and are not malware-family indicators.
- If Microsoft's certificate were compromised, the signer match would be misleading — however, the signer-history record shows 2/2 prior samples safe, and a stolen Microsoft cert would trigger immediate revocation and widespread AV alerts, which are absent here.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
