TL;DR: Twitter acknowledged a knowledge breach that will have unmasked pseudonymous person accounts. While it did not float any precise numbers, earlier stories indicated a vulnerability uncovered greater than 5.4 million Twitter IDs and related telephone numbers and e-mail addresses. Twitter patched the safety gap in January, however a “unhealthy actor” claims he used it the month earlier than to scrape the information.
Last week, Twitter confirmed that hackers had compromised some accounts on its platform. Developers created the flaw with a June 2021 replace for its Android consumer, that allowed a nasty actor to affiliate person accounts with e-mail addresses and telephone numbers. Twitter discovered of the vulnerability by way of its bug bounty program in January 2022 and patched it instantly considering that no person had been affected.
However, final month BleepingComputer reported it had discovered a database on a hacker discussion board containing the telephone numbers and e-mail addresses related to over 5.4 million Twitter accounts.
“Hello, at present I current you information collected on a number of customers who use Twitter through a vulnerability. (5485636 customers to be precise),” the hacker who calls himself “satan” mentioned in his submit. “These customers vary from Celebrities, to Companies, randoms, OGs, and so forth [sic].”
Restore Privacy notes that satan needs to get at the very least $30,000 for the stolen information and mentioned that he’d already had some bites from events.
A safety researcher and bug bounty hunter going by “zhirinovskiy” says the flaw lets anybody acquire the Twitter ID of any person by submitting a telephone quantity/e-mail. The exploit works even when a person’s account is ready to be undiscoverable within the settings. It additionally requires no authentication — only a handful of code.
“The bug exists as a result of proccess of authorization used within the Android Client of Twitter,” zhirinovskiy mentioned, who reported the flaw by way of HackerOne. “Specifically within the procces of checking the duplication of a Twitter account [sic].”
Essentially, satan would feed the system telephone numbers or emails and it might return whether or not these have been related to Twitter IDs. From there it is a pretty simple matter to create a profile from publicly out there posts and different data.
Zhirinovskiy reported the flaw to Twitter on January 1, and builders issued a repair on January 13. However, satan claims he collected the information in December 2021 earlier than it was patched. Some have steered that satan and zhirinovskiy are the identical particular person and that he’s attempting to money out on each ends. Devil denies these allegations with virtually an excessive amount of vigor — as if he has one thing to cover.
“I do not wish to white hat in bother who reported it on H1 [sic],” he informed BleepingComputer. “I assume lots of people try to attach him to me, I’d be pissed if I used to be him. So I cant stress this sufficient I’ve nothing to do w him nor H1.”
Twitter’s affirmation doesn’t point out the variety of compromised person accounts, however it’s fairly clear we’re coping with the identical vulnerability that zhirinovskiy reported and satan exploited. The firm mentioned that it might notify affected customers, presumably by way of their now uncovered e-mail handle. It notably famous nameless accounts.
“If you use a pseudonymous Twitter account, we perceive the dangers an incident like this will introduce and deeply remorse that this occurred. To maintain your id as veiled as attainable, we advocate not including a publicly identified telephone quantity or e-mail handle to your Twitter account.”
Although passwords weren’t compromised, Twitter advises any customers with issues to make use of two-factor authentication apps or {hardware} safety keys to guard their accounts.
