Having up-to-date backups stored safely offline where they can’t be affected by an attacker is an important defense against ransomware. Refusing to pay any ransom demand is a strong position to send a message to attackers that extortion will not be effective. Ransomware that affects all computers in an organization typically isn’t a sudden infection with zero warnings. Ransomware typically comes after several weeks of network profiling as the threat actors identify key infrastructure to target. The best defense strategy for combatting ransomware is to quickly detect signs of infection on workstations and servers using Endpoint Detection and Response (EDR) tools. By quickly responding to threats, defenders can cut off attackers’ access to compromised systems and the network as a whole.
