How can someone identify if their computer is under a ransomware attack? What are the warning signs?
Warning signs that indicate a computer may be under a ransomware attack include:
1. Pop-up messages: Unexpected messages demanding payment to unlock files or restore system access.
2. File encryption: Sudden inability to access files with an unfamiliar extension or a ransom note appearing in folders.
3. Changed file extensions: Files having unusual extensions (e.g., .locky, .crypt, .xtbl) added to them.
4. Desktop wallpaper change: Wallpaper changing with a ransom message or instructions on how to pay the ransom.
5. Missing or inaccessible files: Important files suddenly becoming inaccessible or missing from the computer.
6. Unusual network activity: Ransomware may try to communicate with command and control servers, leading to increased network traffic.
7. Slow performance: Significant slowdown in computer performance due to the ransomware’s encryption processes.
If you suspect your computer is under a ransomware attack, disconnect it from the internet immediately to prevent further encryption and seek professional assistance to contain the situation.
