Types of Ransomware: How Cybercriminals Attack

Ransomware can be classified into various types based on their attack methodology and impact. Some of the most common types include:

1. Crypto Ransomware: Encrypting Your Data for Ransom

• Encrypts files on a victim’s system, making them inaccessible until a ransom is paid.

• Examples: WannaCry, REvil, LockBit.

2. Locker Ransomware: Locking Out Users from Their Devices

• Locks users out of their system, preventing access to files and applications.

• Displays a ransom note demanding payment to unlock the device.

• Examples: Police Locker, WinLocker.

3. Double Extortion Ransomware: Data Theft and Blackmail

• Not only encrypts files but also exfiltrates data, threatening to release it if the ransom is not paid.

• Examples: Maze, Clop, DarkSide.

4. Ransomware-as-a-Service (RaaS): Hacking Made Easy

• A model where cybercriminals offer ransomware tools to affiliates who execute attacks in exchange for a commission.

• Examples: MedusaLocker, Dharma.

5. Mobile Ransomware: Attacking Smartphones and Tablets

• Targets Android and iOS devices, often spreading through malicious apps.

• Examples: Svpeng, Koler.

Current Issues in Ransomware Attacks: Evolving Threats and Challenges

Ransomware threats are evolving rapidly, and the following issues highlight their growing impact:

• Rise of Ransomware-as-a-Service (RaaS): Cybercriminals are now offering ransomware kits to less-experienced hackers, increasing the number of attacks worldwide.

• Targeting Critical Infrastructure: Healthcare, finance, and energy sectors remain primary targets, disrupting essential services.

• Increasing Demands and Payments: The average ransom demand has skyrocketed, with some companies paying millions to recover data.

• Exploitation of Zero-Day Vulnerabilities: Hackers exploit unpatched software vulnerabilities to gain access to systems.

• Involvement of Nation-State Actors: Some ransomware groups have ties to state-sponsored cyber activities, escalating geopolitical tensions.
