Executive Summary
In 2022, an API vulnerability in Twitter, present since a June 2021 update, allowed anyone to submit an email address or phone number and resolve it to the associated account, even where users had disabled that lookup. Attackers abused the flaw to compile datasets linking private emails and phone numbers to public profiles. A core set of roughly 5.4 million accounts was offered for sale in July 2022 and dumped freely in November 2022; additional and larger scraped sets (into the hundreds of millions) also circulated. Public profile fields included names, usernames, bios, locations, profile photos, and account metadata.
ObscureIQ assessment: Because the flaw tied otherwise-public profiles to private contact identifiers, the data is especially useful for unmasking pseudonymous users and for building enriched target profiles combining handle, real name, location, and contact point.
Breach Impact
The critical harm is the de-anonymizing link between a public handle and a private email or phone number, enabling doxxing, targeted phishing, SIM-swap reconnaissance, and identification of pseudonymous accounts.
