Zacks Data Breach (2020)

Investment research company Zacks announced a breach in December 2022 initially believed to impact 820k customers. By June 2023, however, a dataset with almost 9M Zacks customers emerged on a renowned hacking forum. The data, most recent from May 2020, included names, usernames, email and physical addresses, phone numbers, and passwords stored as unsalted SHA-256 hashes.
