A hacker claims to have obtained data of 400M Twitter users

A threat actor is selling a database on a well-known hacker forum, which they claim contains public and private data, including phone numbers and email addresses, of over 400 million Twitter users. The data was allegedly scraped via a now-patched API vulnerability. The seller is asking $200,000 for the database.

As proof of their claims the seller provided a sample of 1,000 Twitter accounts allegedly belonging to celebrities, politicians, journalists, corporations, and government agencies, including Donald Trump JR, Brian Krebs, and others.

According to researches, the leaked samples appear to be legitimate, however, at this point it’s not possible to verify that there are indeed 400 million users in the database. It appears that the data was scraped using an API bug previously linked to the August data breach that affected 5.4 million Twitter users.

China’s ByteDance admits TikTok employees accessed data of users

China-based ByteDance, the owner of Tik Tok social media platform, has admitted that its employees inappropriately accessed TikTok data of some US journalists in an attempt to identify the source of leaks to the media.

The revelation comes following an internal investigation at the company launched after a Forbes report alleging that the company planned to use the TikTok app to track certain US users’ locations. ByteDance’s investigation revealed that several employees based in the US and China obtained IP addresses and other personal data from two reporters and an unspecified number of US users they contacted in order to determine whether they were in the same location as ByteDance employees suspected of leaking confidential information. However, this plan was unsuccessful, partly because the IP addresses only revealed approximate location data.

According to ByteDance, all employees involved in the operation were fired.

The suspect, Avraham Eisenberg, was arrested in Puerto Rico and charged with commodities fraud and commodities manipulation.

Eisenberg later returned $67 million to Mango Markets.
