National Public Data Published Its Own Passwords

Read Time:4 Minute, 53 Second

New details are emerging about a breach at National Public Data (NPD), a consumer data broker that recently spilled hundreds of millions of Americans’ Social Security Numbers, addresses, and phone numbers online. KrebsOnSecurity has learned that another NPD data broker which shares access to the same consumer records inadvertently published the passwords to its back-end database in a file that was freely available from its homepage until today.

In April, a cybercriminal named USDoD began selling data stolen from NPD. In July, someone leaked what was taken, including the names, addresses, phone numbers and in some cases email addresses for more than 272 million people (including many who are now deceased).

NPD acknowledged the intrusion on Aug. 12, saying it dates back to a security incident in December 2023. In an interview last week, USDoD blamed the July data leak on another malicious hacker who also had access to the company’s database, which they claimed has been floating around the underground since December 2023.

Following last week’s story on the breadth of the NPD breach, a reader alerted KrebsOnSecurity that a sister NPD property — the background search service recordscheck.net — was hosting an archive that included the usernames and password for the site’s administrator.

A review of that archive, which was available from the Records Check website until just before publication this morning (August 19), shows it includes the source code and plain text usernames and passwords for different components of recordscheck.net, which is visually similar to nationalpublicdata.com and features identical login pages.

The exposed archive, which was named “members.zip,” indicates RecordsCheck users were all initially assigned the same six-character password and instructed to change it, but many did not.

According to the breach tracking service Constella Intelligence, the passwords included in the source code archive are identical to credentials exposed in previous data breaches that involved email accounts belonging to NPD’s founder, an actor and retired sheriff’s deputy from Florida named Salvatore “Sal” Verini.

Reached via email, Mr. Verini said the exposed archive (a .zip file) containing recordscheck.net credentials has been removed from the company’s website, and that the site is slated to cease operations “in the next week or so.”

“Regarding the zip, it has been removed but was an old version of the site with non-working code and passwords,” Verini told KrebsOnSecurity. “Regarding your question, it is an active investigation, in which we cannot comment on at this point. But once we can, we will [be] with you, as we follow your blog. Very informative.”

The leaked recordscheck.net source code indicates the website was created by a web development firm based in Lahore, Pakistan called creationnext.com, which did not return messages seeking comment. CreationNext.com’s homepage features a positive testimonial from Sal Verini.

There are now several websites that have been stood up to help people learn if their SSN and other data was exposed in this breach. One is npdbreach.com, a lookup page erected by Atlas Data Privacy Corp. Another lookup service is available at npd.pentester.com. Both sites show NPD had old and largely inaccurate data on Yours Truly.

The best advice for those concerned about this breach is to freeze one’s credit file at each of the major consumer reporting bureaus. Having a freeze on your files makes it much harder for identity thieves to create new accounts in your name, and it limits who can view your credit information.

A freeze is a good idea because all of the information that ID thieves need to assume your identity is now broadly available from multiple sources, thanks to the multiplicity of data breaches we’ve seen involving SSN data and other key static data points about people.

There are numerous cybercriminal services that offer detailed background checks on consumers, including full SSNs. These services are powered by compromised accounts at data brokers that cater to private investigators and law enforcement officials, and some are now fully automated via Telegram instant message bots.

In November 2023, KrebsOnSecurity wrote about one such service, which was being powered by hacked accounts at the U.S. consumer data broker USInfoSearch.com. This is notable because the leaked source code indicates Records Check pulled background reports on people by querying NPD’s database and records at USInfoSearch. KrebsOnSecurity sought comment from USInfoSearch and will update this story if they respond.

The point is, if you’re an American who hasn’t frozen their credit files and you haven’t yet experienced some form of new account fraud, the ID thieves probably just haven’t gotten around to you yet.

All Americans are also entitled to obtain a free copy of their credit report weekly from each of the three major credit bureaus. It used to be that consumers were allowed one free report from each of the bureaus annually, but in October 2023 the Federal Trade Commission announced the bureaus had permanently extended a program that lets you check your credit report once a week for free.

If you haven’t done this in a while, now would be an excellent time to order your files. To place a freeze, you’ll need to create an account at each of the three major reporting bureaus, EquifaxExperian and TransUnion. Once you’ve established an account, you should be able to then view and freeze your credit file. If you spot errors, such as random addresses and phone numbers you don’t recognize, do not ignore them. Dispute any inaccuracies you may find.
