Beauty Success: 5.17 million customers claimed, unconfirmed
A hacker claims over 10.2 million rows, reduced to 5.17
million unique profiles, at French beauty retailer Beauty Success. No
confirmation from the retailer to date.
⚠️ Claimed by a hacker, not confirmed by Beauty
Success. No public statement from the retailer confirming this leak was found at
the time of writing. This case file documents a large-scale claim, not an established fact
— but the sheer size of the claimed figure justifies covering it despite the lack of
confirmation.

Timeline
CLAIMED
August 21, 2026
A hacker using the alias "misere" publishes a claim on a criminal
forum covering more than 10.2 million rows of Beauty Success customer data, reduced to
5,169,727 unique records after deduplication.
UNCONFIRMED
Since
The shown sample combines names, emails, complete dates of
birth, customer identifiers and internal account codes. The hacker claims access came
through a third-party vendor, a relationship not verified. No public confirmation from
Beauty Success has been identified to date.
📊A huge figure, a missing confirmation
With 5.17 million unique records claimed, this leak would, if confirmed, be one of
the largest documented on this site for a retail chain. It's precisely because the
figure is so large that it deserves documentation — while maintaining the essential
distinction: a massive figure claimed by a hacker remains a claim until an independent
confirmation exists.
What it changes for you
If you are or were a Beauty Success customer (loyalty card, online purchase, or in-store
service), your name, email and complete date of birth could be in this file — pending
confirmation. The name + email + date-of-birth combination allows much more precise
identification than an isolated email, and facilitates targeted phishing posing as the
retailer. See From Leak to Scam.
🔒 Be wary of any email claiming to be from Beauty Success and
citing your date of birth or loyalty card number to appear legitimate — that's not proof
of authenticity.
