As reported by Bleeping Computer, an underground hacking forum thread from January has been discovered which claims that Zacks has fallen victim to yet another data breach. This latest breach, the third since 2022, is said to be the largest yet – with the personal information of 12 million people being leaked online.

“The 2024 breach included 12 million unique email addresses along with IP and physical addresses, names, usernames, phone numbers and unsalted SHA-256 password hashes. Zacks did not respond to multiple attempts to contact them about the incident,” it explained.
