Cybersecurity Incident Response Team warns of global ransomware attack in progress

Guyana National Cybersecurity Incident Response Team (GNCIRT) 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.

IT Leaders are advised to inform their users to be extremely cautious in their online activities.

Network or system administrators are strongly advised to apply the latest Microsoft patch to all computer systems (please see Microsoft’s Security Bulletin MS17-010).

In the event that a Government computer becomes infected with the ‘Wanna Cry’ ransomware,
take the following steps:
• Disconnect and quarantine the infected system by removing it from your network
• Do NOT pay the ransom
• Immediately inform GNCIRT
