Zacks (2024) Data Breach (2024)

If you are a customer of Zacks (2024), here’s what’s now in circulation.

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.

Zacks (2024) Data Breach (2024)

On June 22, 2024, investment research firm Zacks appeared in a fresh data breach listing on Have I Been Pwned, confirming that records belonging to 12 million unique email addresses had been published to a popular hacking forum. The exposed information includes names, usernames, unsalted SHA-256 password hashes, email addresses, phone numbers, physical addresses, and IP addresses. This incident follows a separate breach the company acknowledged in 2023, with the new dataset described as a superset containing millions of additional records.

Reported Details from the Disclosure

The primary listing on Have I Been Pwned states that the 2024 Zacks breach contains 12 million unique email addresses along with names, usernames, phone numbers, physical addresses, IP addresses, and unsalted SHA-256 password hashes. The notification does not specify the exact attack vector or the precise date the data was exfiltrated. Zacks did not respond to multiple attempts by researchers to obtain comment or clarification. The disclosure explicitly notes that this dataset represents a superset of information from the organization’s previously confirmed 2023 breach.

Unsalted SHA-256 hashes mean that any password cracked from this collection can be used immediately on other sites where victims reused the same password.

Why This Matters for You and Your Family

If you or anyone in your household has used Zacks’ investment research services, your personal information is now available to cybercriminals. Names paired with physical addresses, phone numbers, and email addresses create a ready-made profile for identity theft, phishing campaigns, or fraudulent loan applications. The inclusion of password hashes raises the immediate risk that attackers will attempt to crack them and then test those credentials across banking, email, and shopping accounts. Children or other family members who share an email domain or household address can easily become collateral targets once one person’s data surfaces.

Doxxing and Identity-Chain Risks

Once names, addresses, phones, and usernames leak together, attackers can rapidly build an identity chain that links your online handles to your real-world identity. A cracked password from Zacks can lead to takeover of linked email or social accounts, which in turn expose photos, family relationships, and location history. This information often cascades into doxxing campaigns, SIM-swapping attempts, or targeted harassment. Gaming accounts belonging to you or your children are especially vulnerable because they frequently reuse the same usernames or email addresses seen in the Zacks dataset, turning a financial-research breach into a vector for account theft and further personal exposure.

What to Do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to remove what you can.
  • Rotate the password used on Zacks anywhere it has been reused and immediately enable two-factor authentication with an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next exposure is caught in hours instead of months.
  • Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same addresses and emails.
  • Let remediation specialists handle ongoing takedown requests across data brokers and leak sites on your behalf.

The Zacks breach illustrates how one seemingly routine service can quietly become a gateway that ties your financial interests, home address, and family usernames together for attackers. A forward-looking defense requires more than changing a single password; it demands continuous visibility and expert help to break the chains before criminals exploit them. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.
