Locker Ransomware

Locker ransomware doesn’t encrypt files but instead locks the victim out of their device or system. This approach denies access to the victim until a ransom is paid to regain control.

Scareware

Scareware uses fear tactics to trick victims into paying a ransom. It typically involves displaying false information, such as a fake law enforcement warning claiming the victim has committed illegal activities and must pay a fine.

Mobile Ransomware

As smartphones have become an integral part of our lives, cybercriminals have adapted by developing ransomware targeting mobile devices. This category involves locking victims out of their smartphones and demanding payment.

WannaCry Ransomware

A global cyberattack in 2017, exploited a Microsoft Windows vulnerability to rapidly spread and encrypt files on infected systems. Its massive impact highlighted the urgency of keeping software updated and fortifying cybersecurity measures.

Mitigation and Prevention

Ransomware attacks can have devastating effects on individuals and organizations alike. Implementing proactive measures is essential to safeguard against such threats. Here are some key points to consider:

Regular Backups

Regularly backing up critical data is one of the most effective measures against ransomware. If data is encrypted, victims can restore their systems using backups without having to pay the ransom.

Security Software

Employing robust antivirus and anti-malware solutions can detect and block ransomware threats before they can take hold.

User Education

Educating individuals and employees about the dangers of phishing attacks and suspicious downloads can prevent ransomware from infiltrating systems.
