Twitter admits users data may have been used for advertising

Twitter offers an ad product called "tailored audiences", which lets advertisers upload a contact list of customers that the company then matches to existing users on its social network through phone numbers or emails.

The firm said it was "no longer using phone numbers or email addresses collected for safety or security purposes for advertising". "This was an error and we apologize", Twitter said in a blog post.

Marketers are permitted to use data that social media users intentionally disclose in accounts - in the form of tweets and profile information - to deliver targeted ads in promoted tweets.

Twitter has admitted that it has been using phone numbers and email addresses that its users have provided to enable two-factor security for advertising purposes.

Twitter admits data misuse have been done for advertising goal on its blog post. The issue was fixed on September 17, and the company said that no user data was shared with external entities.

Adding to Twitter's potential troubles, the company finalized an agreement with the FTC in 2011 that alleged the company failed to protect users from security threats. But after the disclosure of Twitter using data for ads made everyone reconsider the protection of data.

However, what Twitter revealed in its statement on Tuesday was that this email matching was referencing addresses that users had submitted exclusively for the objective of enhancing their account security by adding two-factor authentication. This had been a known security flaw for some time, but was only taken down after the account of Twitter CEO Jack Dorsey was compromised.

"We're very sorry this happened and are taking steps to make sure we don't make a mistake like this again", it added.

The problem, however, is that Twitter doesn't know whether your information was revealed or not.

The micro-blogging platform said that it secured Dorsey's account which became victim of "SIM swapping" or "SIM jacking" where a mobile number is transferred to a new SIM card.
