In the summertime of 2022, KrebsOnSecurity documented the plight of a number of readers who had their accounts at big-three shopper credit score reporting bureau Experian hijacked after identification thieves merely re-registered the accounts utilizing a distinct e-mail deal with. Sixteen months later, Experian clearly has not addressed this gaping lack of safety. I do know that as a result of my account at Experian was lately hacked, and the one manner I might get well entry was by recreating the account.
I lately ordered a duplicate of my credit score file from Experian through annualcreditreport.com, however as normal Experian declined to supply it, saying they couldn’t confirm my identification. Makes an attempt to log in to my account straight at Experian.com additionally failed; the location mentioned it didn’t acknowledge my username and/or password.
A request for my Experian account username required my full Social Safety quantity and date of beginning, after which the web site displayed parts of an e-mail deal with I by no means approved and didn’t acknowledge (the total deal with was redacted by Experian).
I instantly suspected that Experian was nonetheless permitting anybody to recreate their credit score file account utilizing the identical private info however a distinct e-mail deal with, a serious authentication failure that was explored in final 12 months’s story, Experian, You Have Some Explaining to Do. So as soon as once more I sought to re-register as myself at Experian.
The homepage mentioned I wanted to supply a Social Safety quantity and cell phone quantity, and that I’d quickly obtain a hyperlink that I ought to click on to confirm myself. The location claims that the cellphone quantity you present will probably be used to assist validate your identification. Nevertheless it seems you would provide any cellphone quantity in the USA at this stage within the course of, and Experian’s web site wouldn’t balk. Regardless, customers can merely skip this step by choosing the choice to “Proceed one other manner.”
Experian then asks to your full title, deal with, date of beginning, Social Safety quantity, e-mail deal with and chosen password. After that, they require you to efficiently reply between three to 5 multiple-choice safety questions whose solutions are fairly often based mostly on public information. Once I recreated my account this week, solely two of the 5 questions pertained to my actual info, and each of these questions involved road addresses we’ve beforehand lived at — info that’s only a Google search away.
Assuming you sail by way of the multiple-choice questions, you’re prompted to create a 4-digit PIN and supply a solution to one in all a number of pre-selected problem questions. After that, your new account is created and also you’re directed to the Experian dashboard, which lets you view your full credit score file, and freeze or unfreeze it.
At this level, Experian will ship a message to the previous e-mail deal with tied to the account, saying sure points of the consumer profile have modified. However this message isn’t a request looking for verification: It’s only a notification from Experian that the account’s consumer knowledge has modified, and the unique consumer is obtainable zero recourse right here apart from to a click on a hyperlink to log in at Experian.com.
And naturally, a consumer who receives one in all these notices will discover that the credentials to their Experian account now not work. Nor do their PIN or account restoration query, as a result of these have been modified additionally. Your solely possibility at this level is recreate your account at Experian and steal it again from the ID thieves!
In distinction, in case you attempt to modify an present account at both of the opposite two main shopper credit score reporting bureaus — Equifax or TransUnion — they’ll ask you to enter a code despatched to the e-mail deal with or cellphone quantity on file earlier than any modifications will be made.
Reached for remark, Experian declined to share the total e-mail deal with that was added with out authorization to my credit score file.
“To make sure the safety of customers’ identities and data, we’ve carried out a multi-layered safety strategy, which incorporates passive and energetic measures, and are consistently evolving,” Experian spokesperson Scott Anderson mentioned in an emailed assertion. “This consists of knowledge-based questions and solutions, and machine possession and possession verification processes.”
Anderson mentioned all customers have the choice to activate a multi-factor authentication methodology that’s requested every time they log in to their account. However what good is multi-factor authentication if somebody can merely recreate your account with a brand new cellphone quantity and e-mail deal with?
A number of readers who noticed my rant about Experian on Mastodon earlier this week responded to a request to validate my findings. The Mastodon consumer @Jackerbee is a reader from Michican who works within the biotechnology trade. @Jackerbee mentioned when prompted by Experian to supply his cellphone quantity and the final 4 digits of his SSN, he selected the choice to “manually enter my info.”
“I put my second cellphone quantity and the brand new e-mail deal with,” he defined. “I obtained a single e-mail in my unique account inbox that mentioned they’ve up to date my info after I ‘signed up.’ No verification required from the unique e-mail deal with at any level. I additionally didn’t obtain any textual content alerts on the unique cellphone quantity. The particularly attention-grabbing and egregious half is that once I sign up, it does 2FA with the brand new cellphone quantity.”
The Mastodon consumer PeteMayo mentioned they recreated their Experian account twice this week, the second time by supplying a random landline quantity.
“The one distinction: it requested me FIVE questions on my private historical past (final time it solely requested three) earlier than proclaiming, ‘Welcome again, Pete!,’ and granting full entry,” @PeteMayo wrote. “I really feel foolish saving my password for Experian; might as effectively simply make a brand new account each time.”
I used to be lucky in that whoever hijacked my account didn’t additionally thaw my credit score freeze. Or in the event that they did, they politely froze it once more once they had been completed. However I absolutely anticipate my Experian account will probably be hijacked but once more until Experian makes some vital modifications to its authentication course of.
It boggles the thoughts that these elementary authentication weaknesses have been allowed to persist for thus lengthy at Experian, which already has a horrible observe file on this regard.
In December 2022, KrebsOnSecurity alerted Experian that identification thieves had labored out a remarkably easy option to bypass its safety and entry any shopper’s full credit score report — armed with nothing greater than an individual’s title, deal with, date of beginning, and Social Safety quantity. Experian mounted the glitch, and acknowledged that it endured for almost seven weeks, between Nov. 9, 2022 and Dec. 26, 2022.
In April 2021, KrebsOnSecurity revealed how identification thieves had been exploiting lax authentication on Experian’s PIN retrieval web page to unfreeze shopper credit score information. In these instances, Experian didn’t ship any discover through e-mail when a freeze PIN was retrieved, nor did it require the PIN to be despatched to an e-mail deal with already related to the buyer’s account.
A number of days after that April 2021 story, KrebsOnSecurity broke the information that an Experian API was exposing the credit score scores of most Individuals.
