Labs / Sysmon triage

A process hash on the intel feed

Briefing

Sysmon can hash every executable it sees start (the Hashes field). The intel team shared three SHA256 values from a campaign that abuses remote support tools.

Select-String is case-insensitive by default, which matters here: Sysmon writes hashes in capitals.
