HEVCut, a photo and video compression app for Apple platforms, now featuring on-device AVIF photo encoding.

The first App Store application to offer on-device AVIF encoding for iOS, providing significant file size reduction (half of HEIC) while preserving quality and HDR content, addressing a gap in Apple's native capabilities.

HEVCut addresses a clear technical gap in Apple's ecosystem: the absence of native AVIF encoding despite decode support. This positions the app as a critical utility for users seeking superior image compression. The claim of reducing HEIC file sizes by half at matched quality is a significant val...

Proof-of-Concept (PoC) for CVE-2020-17103, an LPE in cldflt.sys. The issue is about the PoC's side effects and lack of clean uninstallation/reversion.

Demonstrating an LPE, but without robust error handling or cleanup mechanisms. The implicit positioning is a raw exploit tool, not a production-ready utility.

This issue reveals a critical operational flaw in the MiniPlasma PoC: it leaves systems in a 'semi-broken state' without a clear reversion path. The exploit modifies registry keys related to 'CloudFiles\BlockedApps' and 'Volatile Environment windir', causing system instability like incorrect 'cmd...
