Ransomware is a type of malicious software that encrypts your files and demands a ransom for their release. It's a significant threat to individuals and businesses alike. Here's a brief overview of ransomware and how to protect yourself from it.
What is Ransomware?
Ransomware is a type of malware that blocks access to your computer or encrypts your files until you pay a ransom. The attackers typically demand payment in cryptocurrencies like Bitcoin to make it harder to trace the transaction.
Common Types of Ransomware
- Locky: This ransomware targets Microsoft Office documents and spreadsheets. It spreads via email attachments.
- WannaCry: This ransomware infected hundreds of thousands of computers worldwide in 2017. It exploited a vulnerability in Microsoft's Windows operating system.
- Cryptolocker: This ransomware encrypts your files and demands payment to decrypt them.
How Ransomware Spreads
Ransomware can spread through various means, including:
- Email attachments: Attackers often send emails with malicious attachments that, when opened, install ransomware on your computer.
- Infected websites: Visiting a compromised website can automatically download ransomware to your computer.
- Removable drives: Ransomware can spread through USB drives and other removable storage devices.
Preventing Ransomware
Here are some tips to help you protect yourself from ransomware:
- Keep your software up to date: Regularly update your operating system and applications to patch vulnerabilities.
- Use strong passwords: Use strong, unique passwords for your accounts and enable two-factor authentication where possible.
