A new type of malware exploit has been discovered, in which hackers can gain access to Google accounts without the need for a password, according to a recent report by CloudSEK, a cyber threat monitoring platform. As per the report, this form of cyberattack leverages a vulnerability related to third-party cookies and poses a serious threat to user privacy.

The exploit, originally discovered in October 2023, was first disclosed by a hacker on Telegram, as per a report by the British online newspaper The Independent. According to the hacker, the malware manipulates Google authentication cookies without repeated login requirements.
