This Ransomware Guide includes two resources: CISA and MS-ISAC are distributing this guide to inform and enhance network defense and reduce exposure to a ransomware attack: On September 30, 2020, a joint Ransomware Guide was released, which is a customer centered, one-stop resource with best practices and ways to prevent, protect and/or respond to a ransomware attack. The economic and reputational impacts of ransomware incidents, throughout the initial disruption and, at times, extended recovery, have also proven challenging for organizations large and small. These actors also increasingly use tactics, such as deleting system backups, that make restoration and recovery more difficult or infeasible for impacted organizations. Malicious actors engage in lateral movement to target critical data and propagate ransomware across entire networks. Ransomware incidents have become more destructive and impactful in nature and scope. The monetary value of ransom demands has also increased, with some demands exceeding US $1 million. Malicious actors have adjusted their ransomware tactics over time to include pressuring victims for payment by threatening to release stolen data if they refuse to pay and publicly naming and shaming victims as secondary forms of extortion. Ransomware incidents can severely impact business processes and leave organizations without the data they need to operate and deliver mission-critical services. In recent years, ransomware incidents have become increasingly prevalent among the Nation’s state, local, tribal, and territorial (SLTT) government entities and critical infrastructure organizations. Malicious actors then demand ransom in exchange for decryption.
Ransomware is a form of malware designed to encrypt files on a device, rendering any files and the systems that rely on them unusable.
