What is WannaCry ransomware, and how does it work?

WannaCry is a type of ransomware that encrypts files on a computer or network, rendering them inaccessible until a ransom is paid. It exploits a vulnerability in Windows operating systems, spreading across networks to infect multiple devices.

How can I protect my business from WannaCry ransomware?

To protect your business, ensure all your systems are up-to-date with the latest security patches, especially for Windows operating systems. Use antivirus software, enable firewalls, and educate employees about phishing attacks.

What is the most crucial step in preventing a WannaCry ransomware attack?

Installing security patches for Windows, especially the patch for the vulnerability (MS17-010) that WannaCry exploits, is the most critical step in prevention.

Should I back up my data to prevent WannaCry attacks?

Yes, regularly backing up your data is essential. In the event of a ransomware attack, you can restore your files without paying the ransom.

How does WannaCry spread within a network, and how can I stop it?

WannaCry spreads via the SMB (Server Message Block) protocol used by Windows systems. To prevent this, disable SMBv1 on all devices and limit unnecessary file-sharing protocols.
