Divan de Nysschen, Cybersecurity Architect at NEC XON Every organisation faces the looming threat of ransomware. Malicious actors take control of IT assets and demand ransoms. Whether automated or human-operated, this type of malware encrypts files and folders, compelling victims to pay for decryption keys. Paying up doesn’t necessarily ensure restored access, either, and permanent data loss can be catastrophic. Understanding ransomware attacks
There are two main categories of attacks. Commodity Ransomware Attacks are often automated and spread virally, infiltrating through methods like email phishing and malware delivery. Human-Operated Ransomware attacks involve active infiltration by cybercriminals into an organisation's IT infrastructure. Hallmarks include credential theft and lateral movement with elevated privileges. Commodity ransomware is relatively easier to detect, whereas human-operated variants mimic legitimate IT activities, demanding meticulous attention for detection. Lessons Learned Both commodity and human-operated variants present significant challenges for organisations worldwide. As adversaries become increasingly sophisticated in their tactics, the imperative for proactive defence measures and swift incident response has never been more critical. In the following compilation of lessons learned, we delve into key strategies and insights gleaned from real-world encounters with ransomware attacks:
Ransomware cartels operate ruthlessly, exploiting double extortion tactics to unlock multiple revenue streams within the cybercriminal economy. Proactive cyber strategies and robust safeguards are essential for preparing against these attacks and mitigating potential business damage. Leave a Reply. |
