Understanding Ransomware and Defending Against Ransomware

Ransomware is a sub-category of malware, a class of software designed to cause harm to a computer or computer network. CISA defines ransomware as “an ever-evolving form of malware
designed to encrypt files on a device, rendering any files and the systems that rely on them unusable. Malicious hackers then demand ransom in exchange for decryption. Ransomware hackers often target and threaten to sell or leak exfiltrated information if the ransom is not paid.” Ransomware proliferates in diverse ways, including through exploitation of vulnerabilities, as well as social engineering tactics, such as “phishing” emails that deceive employees within an organization to open attachments that launch the malware that then infects their networks. Once the malware is launched, the malware may connect to a command-and-control server to enable the criminals to move laterally across networks and encrypt and/or exfiltrate the organization’s data. Ransomware victims are typically prompted with a screen informing them that their data has been encrypted, with instructions for how to restore their systems by sending payment via cryptocurrency. Not all attacks result in data encryption, but most do.

A number of factors can influence whether victims agree to pay the ransom demand, including whether they have cyber insurance, the quality of their data backups, and the estimated costs of the system outage. Victims may be more likely to pay if they are concerned their data will be made public.

To defend against Ransomware, keep your computers including the operating systems and applications up to date. Never click on links in emails unless you are sure the sender is a safe sender. Keep your anti-virus software up to date. Always have a backup of your data and applications. Consider how often you need to take a backup and the impact on your business if you lose this data. Alway use secure passwords and use access controls to manage data security.
