A security flaw in the messaging service WhatsApp has been discovered. The bug is able to spread malware and ransomware so that victims end up having to pay to restore their own accounts. The breach apparently only affects the web-based service and as soon as it was discovered, a patch for it was immediately produced by WhatsApp.
It would seem that the WhatsApp web app is a popular choice in the marketplace but not as commonplace as the smartphone version which has four or five times the number of users.
Industry commentators have stated that this was probably a breach waiting to happen as hackers only needed to know the targets’ mobile numbers in order to perpetrate the fraud via a virtual business card which, when accepted by the recipient, allowed the malware to be downloaded.
