Dubsmash — 162 Million Accounts Sold in a Job Lot (2018)

If you are a customer of Dubsmash, here’s what’s now in circulation.

The video-messaging app used PBKDF2, one of the better choices on this list. Its data still ended up on Dream Market in February 2019, in the first of the GnosticPlayers batches — sold beside MyFitnessPal, MyHeritage and a dozen others.

Several breach datasets bundled as one dark-market listing

What happened

In December 2018 the video messaging service Dubsmash lost 161,749,950 unique email addresses along with usernames, names, phone numbers, geographic locations, spoken languages and passwords hashed with PBKDF2.

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

In February 2019 the data appeared for sale on the dark-web marketplace Dream Market, in the first of several batches posted by a seller using the name GnosticPlayers — a listing of roughly 620 million accounts drawn from sixteen sites at once, Dubsmash's 162 million among them. It then circulated more broadly.

PBKDF2 did its job

PBKDF2 is a deliberately slow, salted key-derivation function — the same family of defence as bcrypt. Against it, mass password recovery is impractical, and a reasonable password from a Dubsmash account is very likely still intact.

So on the narrow question most people ask — do I need to change my password? — the honest answer for Dubsmash is: only if you reused it somewhere that stored it badly. That caveat is doing real work, because several of the sites sold in the very same listing did store it badly.
