Defend against ransomware

Ransomware is a type of malicious software, or malware. After being downloaded to a server or a user’s computer, ransomware encrypts files on the device, blocking access and rendering files unusable until a ransom is paid. Versions like REvil and WannaCry ransomware are responsible for some of the largest and most devastating cyberattacks. Ransomware may be spread through Trojan files in an email that appears to be legitimate, but actually contains malware. Botnets like the massive Meris botnet may also be used to propagate ransomware or find vulnerabilities that can be exploited by ransomware gangs.

Most ransomware attacks use social engineering techniques like phishing emails or fake websites to dupe users into revealing credentials that allow attackers to gain access to an IT environment. Then the malware uses lateral movement to find and infect high-value assets. Some ransomware spreads like a worm throughout the network, and some are botnets that infect thousands or millions of machines with malware that gives attackers the ability to control the devices.

Having a strong incident response plan is key to responding to ransomware, as well as making sure you have the right security solutions that can stop it. Akamai’s security solutions enable you to protect against ransomware by reducing the chance of initial infection as well as allowing you to stop lateral movement in real time, containing the breach and making recovery easier.
