Sometimes, security researchers offer decryptors that can unlock files for free, but they aren’t always available and don’t work for every ransomware attack. As soon as a malicious email is on its way to the recipient, Hornetsecurity ATP will detect it and prevents the delivery. Forensic technicians can ensure systems aren’t compromised in other ways, gather information to better protect organisations going forward, and try to track down the attackers. Hornetsecurity Advanced Threat Protection (ATP) provides you with a comprehensive IT security concept that detects and protects from complex attacks such as CEO fraud, spear phishing, whaling and also ransomware. Ĭryptolocker ransomware attacks are a crime, and organisations should call law enforcement if they fall victim. That decision should be based on the type of attack, who in your network has been compromised, and what network permissions the holders of compromised accounts have.

Known as crypto locker, it encrypts all the data on a computer’s hard drive and holds it ransom for a fee, typically in the 300 range.
