Net-new tlemetry looked good in test rules. The likely_benigns are misses on AS and is indicative of the activity we'd like to see. There's a client with a bunch of benigns that we have access to, I checked those all and it was part of a pen test... marking as ready for review! |

Description
From a runner, want to let this sit for a few days to see how it does and iterate from there. Hopefully we get some samples.
Expanding the scope of the sendgrid alert to account for impersonation that doesn't contain sendgrid in the sender name but still is very much sendgrid impersonation.
