Ransomware: The Future of Ransomware – Emerging Trends and How to Prepare
What is ransomware?
Ransomware is malicious software (malware) designed to block access to a computer system or encrypt files until a ransom is paid to the attacker. Once the ransomware has infected a system, it typically encrypts files or locks the system, rendering the data or device inaccessible to the user. The attacker then demands payment, often in cryptocurrency, in exchange for the decryption key or restoring system access.
Ransomware attacks are increasingly sophisticated, and businesses need to adapt to these evolving threats. Let's take a look at emerging trends and strategies for adequate preparation.
Emerging Trends
-
1. Double and Triple Extortion: Attackers now encrypt data, steal it, and threaten public release if the ransom is unpaid. Some also target backup systems for added leverage.
-
2. Ransomware-as-a-Service (RaaS): Ransomware is now commercially available, allowing less skilled attackers to execute sophisticated attacks, increasing the frequency of incidents.
-
3. Targeted Attacks on Critical Infrastructure: Sectors like healthcare and energy are targeted due to their high value and potential disruption impact.
-
4. Advanced Encryption and Evasion Techniques: Modern ransomware uses complex encryption and evasion tactics, including fileless ransomware that leaves minimal traces.
-
5. Social Engineering and Phishing: Many ransomware attacks start with phishing or social engineering to gain initial network access.
How to Prepare
Strengthen Backup Strategies: Regularly back up data and store backups securely offline or in an immutable format—test backups for quick restoration.
