DarkBeam leaks billions of email and password combinations

Each time a breach like this happens I want to download the file and check if

1. My emails are in the dataset, and

2. Any of my passwords are in that dataset.

I really just want the collection of passwords so that I can use it as a check against any of my current passwords.

[EDIT: I know about haveibeenpwned.com; I'm not asking for a service that I send a http request to to determine if a single username exists in the db, I want the db itself so I can chuck it into sqlite and check multiple records at a single time, quickly, for both usernames alone and passwords alone

I also believe it's a bad idea to ask a third-party to perform the check. Even if you trust that third-party now, there is no way to ensure that trust in the future - i.e. it gets bought, breached or pwned itself in the future and best case scenario is that the record of your username lookup is available as "confirmed". Without visiting that site, no one would never know if that record was a throwaway or not.]

Darkbeam was acquired by apexanalytix only two days ago. [0] Hope they are still happy with their purchase...

The data breach announcement is a bit vague on the meaning of “login pairs”. The best practices of breaches databases of the like of https://haveibeenpwned.com/ is to maintain records of login matter (username, email, password etc) in a strongly hashed format. This still enables searching and comparing but not extracting for later use. Why the database here looks like plain text is totally unclear. Or maybe the passwords are hashed here also (which anyway exposes email addresses)?

The company I work for (stytch.com, we provide an authentication API) tracks breached passwords and, depending upon config, will invalidate passwords that have been leaked. Will be interesting to watch our logs over the coming weeks.

I suppose it would require a good few domains and or public mail boxes but imagine if one was to create n fake users for each real user. If any of the fake users log-in on their account all users are forced to change their password.

>Use our personal data leak checker to see if your data – email, phone number, or password – has been leaked.

What is the chance that my email and phone number aren't everywhere? Email and phone aliases are still rare.

Culprit: non-password protected instances

The irony is darkbeam positions itself as a digital risk management platform. A based SOC2 security audit would reveal these vulnerabilities.

That sounds like a slam-dunk GDPR violation case and a hefty fine.

Oh the irony

Multifactor authentication or bust.

No evidence is presented that anybody but the security researcher noticed the unprotected data. The data is a compilation of previously leaked emails.
