ALT Upon boot crashdmp.sys has clobbered MsMpEng.exe, destroying & resizing it to 666 MB. It also still holds the file handle, with NONE share access. ▸ No system crash needed, only reboot. ▸ Defender is just an example; works versus anything (try ntoskrnl.exe). ▸ Dedicated dump is not the only bootside kill; at least 4 more distinct yet similar ways. ⚠️ Administrative access required. LPE exploit not included, and sold separately where legally available. Consult your local security specialist before use. Side effects may include boot failures and audit logs. Void where prohibited. 📋 crashdmp.sys IoCreateFile call: ▸ access: 0x150003, read|write|delete|wdac|sync ▸ share: 0, none ▸ disposition: 0, file_supersede (create/replace) ▸ io options: 0x0102, io_open_paging_file|io_no_parameter_checking ▸ options: 0x900A, write_through|no_intermediate_buffering|delete_on_close|no_compression Bonus: 🕵️ Spot at least one of reg.exe tricks I've used; call it out in the reply to get a cat emoji!
