amaltsev Are you sure this is a cyberattack and not a bug? According to most reports I've read, this is due to a failure converting to a new date and occurred at midnight UTC.

SABBIRRUBAYAT Where do you see that there is an 'Cyber Attack' ?

It seems there is a bug in the moduoe 'FIP-FS' if you look in your Eventlog

The FIP-FS "Microsoft" Scan Engine failed to load. PID: 20132, Error Code: 0x80004005. Error Description: Can't convert "2201010004" to long.

Looks like there are using long in there application
with an max number of
214748 3647 and they try (date looks like?) to parse and higher number 2201010004

A solution without a reboot from servies is:

Set-MalwareFilteringServer -Identity <<SERVERNAMEHERE>> -BypassFiltering $true

Please note!! This is a temporary solution! get a good virus, mallware and spam scanner on your Exchange server from a third party!
