Understanding Ransomware

What is Ransomware?

Ransomware is a type of malicious software designed to block access to a computer system or encrypt its data until a ransom is paid. The attackers often demand payment in cryptocurrency, making the transaction difficult to trace.

Ransomware is a form of malware that locks or encrypts files on a victim’s computer, demanding a ransom payment in exchange for the decryption key. There are two primary types of ransomware:

• Encrypting Ransomware: Encrypts valuable files, making them inaccessible without a decryption key.
• Locker Ransomware: Locks the victim out of their device entirely, preventing access to files and applications.

How Ransomware Works

Ransomware typically infiltrates your system through deceptive tactics such as phishing emails or malicious downloads. Once inside, it encrypts files or locks your screen, rendering your data inaccessible. The attackers then demand a ransom, usually with a tight deadline to increase urgency.

Types of Ransomware

• Encrypting Ransomware: Encrypts files and demands payment for the decryption key.
• Locker Ransomware: Locks you out of your device entirely.
• Scareware: Displays fake warnings and demands money for resolving non-existent issues.
• Doxware: Threatens to release sensitive data unless a ransom is paid.

How Does Ransomware Spread?

Ransomware can infect systems through various methods, including:

• Phishing Emails: Phishing emails are the most common method used by attackers. They often masquerade as legitimate communications, luring victims into clicking malicious links or downloading infected attachments.
• Malicious Attachments and Links: Attachments and links in emails, social media messages, or ads can be carriers of ransomware. Once clicked or downloaded, they can execute the malware on your system.
• Exploiting Software Vulnerabilities: Outdated software with unpatched vulnerabilities can be exploited by ransomware to gain entry into your system. Regular updates and patches are crucial to mitigate this risk.
