MemLoaderCustomize.sys
Nextron Systems identifies these samples as MemLoaderCustomize kernel PE-loader variants. Capabilities reported across the pair include kernel hooking, module hiding, and deletion; module hiding is specifically attributed to the c6825f94 sample. Static analysis confirms matching loader implementations that allocate image memory, copy PE sections, apply relocations, resolve kernel imports, and prepare mapped-image execution, together with file-deletion helpers. Both contain a MemLoaderCustomize.pdb build path. Module hiding and successful runtime self-deletion remain source-reported rather than dynamically tested.
