Nevertheless, the brand new QR code is to hyperlink a brand new machine, the attacker’s, to the sufferer’s WhatsApp account.
“If the goal follows the directions on this web page, the menace actor can achieve entry to the messages of their WhatsApp account and have the potential to exfiltrate this information utilizing current browser plugins, that are designed for exporting WhatsApp messages from an account accessed through WhatsApp Internet,” explains Microsoft.
