Suspicious IP reporting

Fri Feb 5 06:04:43 UTC 2021

While I agree that reporting something not observed just creates a lot of
unnecessary work for the recipient in processing all of the unsubstantiated
reports (that don't match traffic logs, etc), that isn't the point of my
message. I would point out that most people would call such reports spam at
the least. Another term for the same thing, brigading, rarely works out
satisfactorily for anyone either.

Success with asking a service provider to take action is always going to be
a crapshoot, but it will almost never be fast in any case.

If there is a C2 server known to be contacting a host you manage, the
bigger problem to me would seem to be the compromised host, rather than the
C2. It could be exfiltrating sensitive data to the attacker right now. An
established attacker will have dozens or hundreds of C2s. Do you intend to
pursue all of them individually?

If the organization isn't prepared to start an appropriate incident
response on a compromised host in a timely manner, perhaps they will learn
from and correct that security posture weakness in the future.

Regards
Dave
