Crypto24 is known for targeting organizations with ransomware attacks, often demanding significant ransoms for decryption keys. Their modus operandi involves encrypting vital data and threatening to release it on the dark web unless paid.
Given the increasing frequency of such attacks, organizations must adopt proactive measures to safeguard against ransomware threats. One effective strategy is implementing dark web monitoring to detect potential data breaches early. Additionally, regular security audits and robust employee training programs can fortify defenses against cyber threats.
Organizations can also use tools like the email breach checker to monitor for potential breaches and protect their data integrity.
