Hackers compromised millions of users' Adobe login information in a 2013 breach.
Adobe at first said 3 million accounts were affected, then revised that number to 38 million, while cybersecurity watchdog Sophos said it found over 150 million breached records in a database dump of the stolen data. At the time, Adobe told The Verge that that figure could include "many invalid Adobe IDs, inactive Adobe IDs, Adobe IDs with invalid encrypted passwords, and test account data."
