WannaCry is still at large, and there have been reports of victims of the cyber-attack in nearby countries such as Malaysia and Singapore.
Computers running Microsoft Windows are mostly affected by the ransomware, and according to Kaspersky Labs, the most vulnerable is Windows 7.
Data released by Kaspersky Labs yesterday revealed that about 98 per cent of infected PCs around the world were running an out-of-date version of Windows 7. Clearly the users are running on very old PCs and have not updated their OS with the latest security patch prior to the attack.
Originally released in 2009, Windows 7 is currently the oldest version of Windows that is still supported by Microsoft. Last month, the company discontinued support for its aging Windows Vista.
Ransomware is a type of malware virus that encrypts files in a PC and demands ransom for those files to be decrypted. In the case of WannaCry, the ransomware’s perpetrator asks the affected user to pay the ransom in the form of digital currency called Bitcoins. There is no guarantee that paying the ransom would help the user recover the encrypted files.
Earlier reports suggested that WannaCry infects PCs via phishing emails, mainly in the form of attachments and links.
Microsoft said that those who are running its free antivirus software or have Windows Update enabled are protected from the ransomware.
To date, WannaCry has infected more than 300,000 computers in 150 countries.
Currently there are no known cases reported in Brunei, the Prime Minister’s Office stated earlier this week.
If you are affected by WannaCry or any cyber-attack, you can contact the Brunei Computer Emergency Response Team (BruCERT) at its hotline 2458001.
