✍🏻 On older Win 👴🏼 it’s
602
event. Also, config files are in bin format with.job
extension and can be parsed by ajobparser.py
script.
Also, scheduled tasks create an XML (on newer) or bin (👴🏼) config files with helpful information like the account used, timestamps and activities scheduled. Simply go to Windows\System32\Tasks
or Windows\SysWoW64\Tasks
(for 32-bit) folders. Bot at.exe
and schtasks.exe
produce this artefact. If you know that’s a malicious task, note the account used to create it, and you have a lead because it’s likely compromised. Bingo!
