WeLeakInfo (weleakinfo.com) suffered a data breach in 2021 that exposed around 11,788 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.
What happened
In March 2021, the Stripe account of the now-defunct WeLeakInfo service was taken over by "pompompurin" after acquiring an expired domain name with an email address used to manage the account. Access to Stripe then exposed almost 12k unique email addresses from customers who'd made credit card payments in order to obtain breached data hosted by WeLeakInfo. The data was subsequently leaked publicly and also included names, payment histories, IP addresses, billing addresses, partial credit card data and the organisation making the purchase.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the WeLeakInfo breach exposed and what each item actually enables:
Direct financial fraud, plus convincing scam calls that quote your real card or account details to establish trust.
Home addresses feed people-search and data-broker sites, which republish them publicly. They also make phishing far more convincing and, in the worst cases, enable real-world harassment.
Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
Reveals your approximate location and internet provider, which adds credibility to targeted scams.
Also listed in this breach: Browser user agent details, Email addresses, Employers, IP addresses, Names, Partial credit card data, Physical addresses, Purchases.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Payment or bank details: Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
- Home addresses: Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
- 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.
- IP addresses: No direct action needed, but be wary of anyone quoting your location as “proof” of identity.
- Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.
This breach put your details on data-broker sites
Because WeLeakInfo 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 data has been circulating for around 5 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.
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.
