What happened
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.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Woflow breach exposed and what each item actually enables:
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Home addresses
Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating. - Phone numbers
Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider. - Names and usernames
Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts. - Email addresses
Treat any message referencing this service with suspicion, and never act on links in unexpected emails. - Confirm you were actually in it
Run a free scan before you spend time on the steps above.
This breach put your details on data-broker sites
Because Woflow exposed home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?
This breach is recent, so the data is actively traded and the risk is at its highest right now.
Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
