Description

This purpose-built kernel loader creates the \.\wifis device and accepts encrypted PE images through IOCTL 0x222000. Its worker thread decrypts input with an RC4-like routine using the embedded key dsmjklsafbv, manually maps the supplied PE image, resolves imports and relocations, and transfers execution to the unsigned payload in kernel memory.
