Active Directory Will Show Multiple Login Failures
CI Security's Hamilton advises security teams to monitor Active Directory for login failures. For example, if you see three login failures in a row on RDP servers, that's a surefire sign the network has been attacked. The same holds for administrative login failures. Because companies didn't have time to prepare for COVID-19, and it looks like working from home will go on for the foreseeable future, it's time to develop a safe list of good IP addresses, Hamilton adds.

Backups no longer enough
Earlier, during a ransomware attack, organizations could remove the virus and restore files from the backup. The ransomware authors' tactics have now changed. They first steal all files that they can, and then encrypt everything. Later, if you don't want to pay the ransom, they threaten to publish your confidential files. In addition to backups, you need now to also take care of encrypting important info, both data at rest and data in transit.
