Detection & Forensics
Consensus, attribution, signatures, code structure, prevalence, and identity.
Detection sources at a glance
The available sources did not agree on a named threat category.
One or more independent reference databases matched this hash.
Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.

Complete recovery guidance and answers for the next decision.
What to do now
This file appears low risk based on the evidence available now.
Use it only as part of software obtained from the developer's official site or another source you independently trust.
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
Keep your antivirus and Windows updates switched on so you stay protected.
Safety FAQ
- libSkiaSharp.dll appears safe. 0 of 75 antivirus engines flagged it. It carries a verified digital signature from Microsoft Corporation. Use it only as part of software obtained from the developer's official site or another source you independently trust.
- libSkiaSharp.dll is a Windows library or loadable module, about 9 MB. Our analysis did not identify a verdict-driving threat signal. It carries a verified digital signature from Microsoft Corporation. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- None — 0 of 75 antivirus engines flagged libSkiaSharp.dll. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
- Yes — libSkiaSharp.dll carries a valid digital signature from Microsoft Corporation, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
- The SHA-256 hash of libSkiaSharp.dll is 9a0d95e8caaa852c70d085af6a40a744242172ad9ea3fd6bc7599875a8a1dbcd, and its MD5 is ef1fabce43fe32ca83260481253f5476. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- Based on the recorded evidence, libSkiaSharp.dll has a low observed risk and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it, verify the source and the exact hash before overriding the warning.
- This report reflects the scan run on June 10, 2026. Because a file's hash never changes, the identity of libSkiaSharp.dll is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
