Ransomware

Ransomware

Ransomware is a type of malware that locks and encrypts a victim's data, files, devices or systems, rendering them inaccessible and unusable until the attacker receives a ransom payment.

How does ransomware work?

The ransomware lifecycle has six general stages:

Stage 1: Malware distribution and infection

Stage 2: Command and control

Stage 3: Discovery and lateral movement

Stage 4: Malicious theft and file encryption

Stage 5: Extortion

Stage 6: Resolution

Recent ransomware trends

So-called big game hunting, in which ransomware operators target large organizations with deep pockets, has exploded in recent years. High-profile ransomware victims and high-impact ransomware attacks have included Colonial Pipeline, JBS USA, the government of Costa Rica, Ireland's national health service, Travelex, CNA Financial and many more.

How to prevent ransomware attacks

Ransomware prevention is a huge challenge for organizations of all types and sizes, with no magic-bullet remedy. Experts say enterprises need a multi-pronged ransomware prevention strategy that includes the following:

1.Defense-in-depth security 2.Advanced security controls

3.Patch management 4.Data backups.

5.Security awareness training
