Microsoft warns of a vulnerability that could easily lead to the loss of TikTok accounts to hackers


Microsoft has detailed a critical vulnerability on TikTok that allows hackers to take over accounts when users click on a malicious link.

Researcher Dimitrios Valsamaras (of the Microsoft 365 Defender research team) said: "Attackers could have taken advantage of the vulnerability to take over an account without the user's knowledge when they clicked on a link that was designed. special design”.

Krause said that the browser on TikTok is capable of collecting sensitive details including passwords, credit card information ... when users interact with any website. However, TikTok has denied the above allegation.
