Identification thieves have been exploiting a obvious safety weak point within the web site of Experian, one of many huge three shopper credit score reporting bureaus. Usually, Experian requires that these searching for a replica of their credit score report efficiently reply a number of a number of alternative questions on their monetary historical past. However till the tip of 2022, Experian’s web site allowed anybody to bypass these questions and go straight to the patron’s report. All that was wanted was the particular person’s identify, deal with, birthday and Social Safety quantity.

The vulnerability in Experian’s web site was exploitable after one utilized to see their credit score file through annualcreditreport.com.

In December, KrebsOnSecurity heard from Jenya Kushnir, a safety researcher dwelling in Ukraine who mentioned he found the tactic being utilized by identification thieves after spending time on Telegram chat channels devoted to the cashing out of compromised identities.

“I wish to attempt to assist to place a cease to it and make it harder for [ID thieves] to entry, since [Experian is] not doing shit and common individuals battle,” Kushnir wrote in an electronic mail to KrebsOnSecurity explaining his motivations for reaching out. “If in some way I could make small change and assist to enhance this, inside myself I can really feel that I did one thing that really issues and helped others.”

Kushnir mentioned the crooks realized they might trick Experian into giving them entry to anybody’s credit score report, simply by modifying the deal with displayed within the browser URL bar at a particular level in Experian’s identification verification course of.

Following Kushnir’s directions, I sought a replica of my credit score report from Experian through annualcreditreport.com — a web site that’s required to offer all Individuals with a free copy of their credit score report from every of the three main reporting bureaus, as soon as per yr.

Annualcreditreport.com begins by asking to your identify, deal with, SSN and birthday. After I equipped that and instructed Annualcreditreport.com I wished my report from Experian, I used to be taken to Experian.com to finish the identification verification course of.

Usually at this level, Experian’s web site would current 4 or 5 multiple-guess questions, akin to “Which of the next addresses have you ever lived at?”

Kushnir instructed me that when the questions web page masses, you merely change the final a part of the URL from “/acr/oow/” to “/acr/report,” and the location would show the patron’s full credit score report.

However once I tried to get my report from Experian through annualcreditreport.com, Experian’s web site mentioned it didn’t have sufficient info to validate my identification. It wouldn’t even present me the 4 multiple-guess questions. Experian mentioned I had three choices for a free credit score report at this level: Mail a request together with identification paperwork, name a telephone quantity for Experian, or add proof of identification through the web site.

However that didn’t cease Experian from exhibiting me my full credit score report after I modified the Experian URL as Kushnir had instructed — modifying the error web page’s trailing URL from “/acr/OcwError” to easily “/acr/report”.

Experian’s web site then instantly displayed my whole credit score file.

Despite the fact that Experian mentioned it couldn’t inform that I used to be truly me, it nonetheless coughed up my report. And thank goodness it did. The report incorporates so many errors that it’s in all probability going to take a great deal of effort on my half to straighten out.

Now I do know why Experian has NEVER let me view my very own file through their web site. For instance, there have been 4 telephone numbers on my Experian credit score file: Solely certainly one of them was mine, and that one hasn’t been mine for ages.

I used to be so dumbfounded by Experian’s incompetence that I requested an in depth buddy and trusted safety supply to strive the tactic on her identification file at Experian. Certain sufficient, when she received to the half the place Experian requested questions, altering the final a part of the URL in her deal with bar to “/report” bypassed the questions and instantly displayed her full credit score report. Her report additionally was replete with errors.

KrebsOnSecurity shared Kushnir’s findings with Experian on Dec. 23, 2022. On Dec. 27, 2022, Experian’s PR workforce acknowledged receipt of my Dec. 23 notification, however the firm has to date ignored a number of requests for remark or clarification.

By the point Experian confirmed receipt of my report, the “exploit” Kushnir mentioned he realized from the identification thieves on Telegram had been patched and now not labored. Nevertheless it stays unclear how lengthy Experian’s web site was making it really easy to entry anybody’s credit score report.

In response to info shared by KrebsOnSecurity, Senator Ron Wyden (D-Ore.) mentioned he was disenchanted — however under no circumstances shocked — to listen to about yet one more cybersecurity lapse at Experian.

“The credit score bureaus are poorly regulated, act as if they’re above the legislation and have thumbed their noses at Congressional oversight,” Wyden mentioned in a written assertion. “Simply final yr, Experian ignored repeated briefing requests from my workplace after you revealed one other cybersecurity lapse the corporate.”

Sen. Wyden’s quote above references a narrative printed right here in July 2022, which broke the information that identification thieves have been hijacking shopper accounts at Experian.com simply by signing up as them at Experian as soon as extra, supplying the goal’s static, private info (identify, DoB/SSN, deal with) however a unique electronic mail deal with.

From interviews with a number of victims who contacted KrebsOnSecurity after that story, it emerged that Experian’s personal buyer assist representatives have been truly telling shoppers who received locked out of their Experian accounts to recreate their accounts utilizing their private info and a brand new electronic mail deal with. This was Experian’s recommendation even for individuals who’d simply defined that this methodology was what identification thieves had used to lock them in out within the first place.

Clearly, Experian discovered it less complicated to reply this fashion, moderately than acknowledging the issue and addressing the foundation causes (lazy authentication and abhorrent account restoration practices). It’s additionally value mentioning that stories of hijacked Experian.com accounts endured into late 2022. That screw-up has since prompted a category motion lawsuit in opposition to Experian.

Sen. Wyden mentioned the Federal Commerce Fee (FTC) and Client Monetary Safety Bureau (CFPB) have to do way more to guard Individuals from screw-ups by the credit score bureaus.

“In the event that they don’t consider they’ve the authority to take action, they need to endorse laws like my Mind Your Own Business Act, which supplies the FTC energy to set robust obligatory cybersecurity requirements for firms like Experian,” Wyden mentioned.

Sadly, none of that is terribly surprising habits for Experian, which has proven itself a very negligent custodian of obscene quantities of extremely delicate shopper info.

In April 2021, KrebsOnSecurity revealed how identification thieves have been exploiting lax authentication on Experian’s PIN retrieval web page to unfreeze shopper credit score information. In these circumstances, Experian did not ship any discover through electronic mail when a freeze PIN was retrieved, nor did it require the PIN to be despatched to an electronic mail deal with already related to the patron’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.

It’s dangerous sufficient that we are able to’t actually decide out of firms like Experian making $2.6 billion each quarter amassing and promoting gobs of our private and monetary info. However there must be some significant accountability when these monopolistic firms have interaction in negligent and reckless habits with the exact same shopper information that feeds their quarterly earnings. Or when safety and privateness shortcuts are discovered to be intentional, like for cost-saving causes.

And as we noticed with Equifax’s consolidated class-action settlement in response to letting state-sponsored hackers from China steal information on practically 150 million Individuals again in 2017, class-actions and extra laughable “free credit score monitoring” providers from the exact same firms that created the issue aren’t going to chop it.


It’s simple to undertake a defeatist angle with the credit score bureaus, who typically foul issues up royally even for shoppers who’re fairly diligent about watching their shopper credit score information and disputing any inaccuracies.

However there are some concrete steps that everybody can take which can dramatically decrease the danger that identification thieves will wreck your monetary future. And fortunately, most of those steps have the facet good thing about costing the credit score bureaus cash, or a minimum of inflicting the info they accumulate about you to turn into much less helpful over time.

Step one is consciousness. Discover out what these firms are saying about you behind your again. Needless to say — honest or not — your credit score rating as collectively decided by these bureaus can have an effect on whether or not you get that mortgage, residence, or job. In that context, even small, unintentional errors which are unrelated to identification theft can have outsized penalties for shoppers down the street.

Every bureau is required to offer a free copy of your credit score report yearly. The best option to get yours is thru annualcreditreport.com.

Some shoppers report that this website by no means works for them, and that every bureau will insist they don’t have sufficient info to offer a report. I’m undoubtedly on this camp. Fortunately, a monetary establishment that I have already got a relationship with affords the flexibility to view your credit score file via them. Your mileage on this entrance might fluctuate, and it’s possible you’ll find yourself having to ship copies of your identification paperwork via the mail or web site.

If you get your report, search for something that isn’t yours, after which doc and file a dispute with the corresponding credit score bureau. And after you’ve reviewed your report, set a calendar reminder to recur each 4 months, reminding you it’s time to get one other free copy of your credit score file.

When you haven’t already accomplished so, think about making 2023 the yr that you just freeze your credit score information on the three main reporting bureaus, together with Experian, Equifax and TransUnion. It’s now free to individuals in all 50 U.S. states to position a safety freeze on their credit score information. It’s also free to do that to your accomplice and/or your dependents.

Freezing your credit score means nobody who doesn’t have already got a monetary relationship with you’ll be able to view your credit score file, making it unlikely that potential collectors will grant new traces of credit score in your identify to identification thieves. Freezing your credit score file additionally means Experian and its brethren can now not promote peeks at your credit score historical past to others.

Anytime you want to apply for brand new credit score or a brand new job, or open an account at a utility or communications supplier, you’ll be able to shortly thaw a freeze in your credit score file, and set it to freeze robotically once more after a specified size of time.

Please don’t confuse a credit score freeze (a.ok.a. “safety freeze”) with the choice that the bureaus will doubtless steer you in the direction of if you ask for a freeze: “Credit score lock” providers.

The bureaus pitch these credit score lock providers as a method for shoppers to simply toggle their credit score file availability with push of a button on a cellular app, however they do little to forestall the bureaus from persevering with to promote your info to others.

My recommendation: Ignore the lock providers, and simply freeze your credit score information already.

One closing notice. Frequent readers right here may have observed that I’ve criticized these so-called “knowledge-based authentication” or KBA questions that Experian’s web site did not ask as a part of its shopper verification course of.

KrebsOnSecurity has lengthy assailed KBA as weak authentication as a result of the questions and solutions are drawn largely from shopper data which are public and simply accessible to organized identification theft teams.

That mentioned, on condition that these KBA questions look like the ONLY factor standing between me and my Experian credit score report, it looks as if possibly they need to a minimum of take care to make sure that these questions truly get requested.
