A DB containing data of 5.4 million Twitter accounts available for sale
A threat actor has leaked data of 5.4 million Twitter accounts that were obtained by exploiting a now-fixed vulnerability in the popular social media platform.
The threat actor is now offering for sale the stolen data on the popular hacking forum Breached Forums. In January, a report published on Hacker claimed the discovery of a vulnerability that can be exploited by an attacker to find a Twitter account by the associated phone number/email, even if the user has opted to prevent this in the privacy options.
“The vulnerability allows any party without any authentication to obtain a Twitter ID(which is almost equal to getting the username of an account) of any user by submitting a phone number/email even though the user has prohibited this action in the privacy settings. The bug exists due to the proccess of authorization used in the Android Client of Twitter, specifically in the procces of checking the duplication of a Twitter account.” ” reads the description in the report submitted by zhirinovskiy via bug bounty platform HackerOne. “This is a serious threat, as people can not only find users who have restricted the ability to be found by email/phone number but an attacker with a basic knowledge of scripting/coding can enumerate a big chunk of the Twitter user base unavailable to enumeration prior (create a database with phone/email to username connections). Such bases can be sold to malicious parties for advertising purposes, or for the purposes of targeting celebrities in different malicious activities”
Twitter confirmed the existence of this vulnerability and awarded Zhirinovsky with a $5,040 bounty.
The website Restore Privacy first discovered the advertisement for the huge trove of data on Breached Forums.
