Stop Ransomware Before It Spreads

Ransomware is a type of malicious software, or malware, designed to encrypt files on a device, rendering them unusable. Attackers demand ransom, usually in cryptocurrency, in exchange for a decryption key. Ransomware attacks are largely introduced through phishing emails, malicious websites, or infected software applications.

Ransomware attacks are unique because of their potentially dual-threat nature. Ransomware not only encrypts data to disrupt business operations but may also involve data exfiltration. In these double extortion attacks, attackers threaten to release or sell sensitive data if their demands are not met, resulting in significant pressure on victims to comply with ransom demands.

Ransomware attacks have evolved drastically, with attackers using more sophisticated tactics such as advanced encryption algorithms that are nearly impossible to break without the decryption key. While traditional ransomware attacks used to be opportunistic, modern ransomware campaigns are more targeted with attackers conducting research to identify high value targets that are more likely to pay large ransoms.

RaaS is a business model that allows amateur cybercriminals to buy ransomware and intrusion playbooks from other skilled cybercriminals. This has led to an increase in both the frequency and sophistication of attacks and lowered the threshold for ransomware attacks.

The main vectors of ransomware attacks are phishing emails, Business Email Compromises (BEC), browser-based attacks like SEO poisoning and malvertising, remote desktop protocol (RDP) abuse, and credential abuse.

Knowing how to prepare for and defend against a ransomware attack is essential. Critical aspects of your protection against ransomware should include hardening systems, rigorous prevention measures, ransomware detection and response, recovery and restoration measures, and plans to inform relevant authorities and affected parties.
