NORCAL’s trusted cyber security partner, CyberScout, offers five tips to protect your systems
Systems across the globe have been under attack by ransomware known as WannaCry that has hit as many as 74 countries since it first appeared on Friday, May 12. This cyberattack has impacted computer systems at hospitals, universities and businesses around the globe. This virus is spread when an email with an encrypted .zip file attachment is opened; it immediately infects and locks the targeted computer. NORCAL’s trusted cyber security partner, CyberScout, offers five tips to protect your systems:
- Keep software current. Patch all endpoint device operating systems, software and firmware as vulnerabilities are discovered. This attack exploits the Server Message Block (SMB) critical vulnerability, which was patched by Microsoft on March 14, MS-17-010.
- Warn and educate users. Ransomware succeeds by tricking users into clicking malicious email attachments and links. Know how to spot phishing emails, avoid clicking on banners or unrecognized links, and only visit trusted sites.
- Back up files regularly to a safe place. If your data is encrypted by malware, a backup may be the only way to recover it. Use a backup facility that is either off your network on a separate network segment at your location.
- Plan your response. Make sure your current Breach Response plan accounts for ransomware so you can shut down and or contain an attack as soon as you recognize it.
- Stay informed. Keep up with cyber security news so that you can respond quickly and appropriately.
