Zacks (2024) Data Breach

What happened

In June 2024, the investment research company Zacks was allegedly breached, and data was later published to a popular hacking forum. This comes after a separate Zacks data breach confirmed by the organisation in 2023 with the subsequent breach disclosing millions of additional records representing a superset of data from the first incident. The 2024 breach included 12M 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.

Exposed data

Recommended actions

• Change your Zacks (2024) password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Zacks (2024) — attackers weaponise breach data quickly.
• Stay alert for smishing (SMS phishing) and SIM-swap attempts using your phone number.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
