Twitter suspends ‘huge network’ of bogus accounts used to match phone numbers to users

Twitter  proclaimed currently that over the holidays, it recognized and close “a huge system of bogus accounts,” along with several others “situated in several countries,” together mistreating a function as to permit them to match phone numbers to user accounts.

TechCrunch already stated this problem on December 24, which is also the day Twitter mentions it that they know the exploitation was taking place. Safety investigator Ibrahim Balic recognizes that a virus in Twitter’s Android app allows him to submit several phone numbers with an official API that changed any linked user account.

The function, if you allowed it, to permit friends who have your number find your Twitter control. Then clearly providing several numbers drives “outside its planned use situation.” And if you changed this function, this issue will not affect you. Luckily this option was in for the EU users. 

Nevertheless, it is opt-out for the other users of all around the world. Thus if you had a phone number connected through your account, it could affect you as well. Moreover, the phone numbers contain those offered for determinations of two-factor verification, so those external of the EU may have been weak to this activity without understanding it. 

We can say that after Twitter was informed to this problem and close the real system (apparently Balic’s), its detectives recognized several other accounts that were abusing this fault, though an illustrative weakened to give a number or an idea. 

According to the company as they stated it insecurity;

“They detect a special high volume of requirements approaching through a single IP address situated within Iran, Israel, and Malaysia.”

“It can be that some of these IP addresses may have drawn to state-sponsored performers,” the post continued. 

This doubt was defensible by the opinion of open reach to twitter from the IPs in Iran, where the stage is blocked from common reach, signifying government participation. Belic, when communicated by TechCrunch, mentioned that his action was not state-sponsored in any way.

Any account supposed to mistreat the function was blocked, and the API itself has been changed to stop any additional abuse of such kind. I inquired the company how many accounts were blocked and will inform this post if they replied to him. Twitter has had several reports where it uncovered or leaked user data from the last year.
