Severity: medium · Patch status: no-fix-needed · Since 2026-05-07
In March 2026, the AI-driven merchant data platform Woflow was named as a victim by the ShinyHunters data extortion group. The group subsequently published tens of thousands of files allegedly obtained from the company, comprising more than 2TB of data. The trove included hundreds of thousands of email addresses, names, phone numbers and physical addresses, with the data indicating it related to Woflow customers and, in turn, the customers of merchants using their platform. Exposed data: email addresses, names, phone numbers, physical addresses. The breach dates from Mar 4, 2026; Have I Been Pwned loaded it on May 7, 2026.
What to do
- If you had a Woflow 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.
