Network-based attacks and their mitigation are of increasing importance in our ever-connected world. Often network-based attacks address valuable data, which the attacker either encrypts to extort ransom or steals to make money reselling, or both. After the infamous WannaCry and NotPetya ransomware attacks in 2017, companies stepped up their cyber defenses. More emphasis was placed on backup and recovery processes so that even when files were destroyed, organizations had copies for quick recovery. However, cyber criminals have also adapted their methods. Instead of simply encrypting files, double or even multiple extortion ransomware now exfiltrates the data first, before encrypting it. In particular, valuable business assets must be checked for unauthorized access and need to be protected.
