Zacks data breach: 8.9M accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2023-06-10
In December 2022, the investment research company Zacks announced a data breach. The following month, reports emerged of the incident impacting 820k customers. However, in June 2023, a corpus of data with almost 9M Zacks customers appeared before being broadly circulated on a popular hacking forum. The most recent data was dated May 2020 and included names, usernames, email and physical addresses, phone numbers and passwords stored as unsalted SHA-256 hashes. On disclosure of the larger breach, Zacks advised that in addition to their original report "the unauthorised third parties also gained access to encrypted [sic] passwords of zacks.com customers, but only in the encrypted [sic] format". Exposed data: email addresses, names, passwords, phone numbers, physical addresses, usernames. The breach dates from May 10, 2020; Have I Been Pwned loaded it on Jun 10, 2023.
What to do
- If you had a Zacks account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
