What is Ransomware?

Ransomware is a malicious type of software that locks or encrypts files, restricting access until the user pays for the information to be released, aka the ransom. The attacker usually demands money, in exchange for the return of access. Anyone can be a ransomware attack target - it extends to individuals, businesses, or government systems, which can have varying degrees of disruption. 

Ransomware can enter computers through a phishing email or by exploiting security vulnerabilities in outdated software. Once it has invaded the system, the user cannot access their files; all they have is a ransom note demanding payment.

Payment of ransom also does not provide a guarantee of data retrieval, and may also raise the possibility of further attacks. Prevention is thus the best solution, which includes - regular backup, timely updating of software, and strong cybersecurity defense systems such as firewalls, antivirus software, advanced threat detection mechanisms, multi-factor authentication, and more such security solutions. 

Finally, general awareness is imperative. Educating employees on how to identify suspicious emails and avoiding risky behaviors can help lower an organization's risk for attack. With various defense plans in place, the risk of an attack through ransomware can be considerably minimized.
