Guyana National Cybersecurity Incident Response Team (Guyana National CIRT) confirms that a global ransomware attack is currently in progress.

The self-spreading ransomware, known as 'Wanna Cry' or 'Wanna Decryptor', exploits a vulnerability in Microsoft's Windows operating system. It is believed that this ransomware is spread through phishing emails, malicious adverts on websites, and questionable apps and programs.

• Do NOT open unsolicited or suspicious emails or links therein

• Do NOT open attachments included in unsolicited e-mails

• Do NOT click on links to unfamiliar or nefarious websites

• Do NOT download applications and programs that have not been verified by an official store

In the event that your computer has been infected with the ‘Wanna Cry’ ransomware, take the following steps:

• Disconnect and quarantine the infected system by removing it from your network

• Apply the latest Microsoft patch to all computer systems (please see Microsoft’s Security Bulletin MS17-010)
