Briefing

lsass.exe holds credentials for everyone logged on to a machine. Reading its memory is how most credential theft tools work. Sysmon event 10 logs process access with the requested rights (GrantedAccess) and a CallTrace of the DLLs involved.

Antivirus and Windows services open lsass with limited rights such as 0x1000 (query limited information) all day. You have JUMP-02’s Sysmon log.
