Equifax, one of the “big-three” U.S. credit bureaus, said today a data breach at the company may have affected 143 million Americans, jeopardizing consumer Social Security numbers, birth dates, addresses and some driver’s license numbers.
In a press release today, Equifax [NYSE:EFX] said it discovered the “unauthorized access” on July 29, after which it hired an outside forensics firm to investigate. Equifax said the investigation is still ongoing, but that the breach also jeopardized credit card numbers for roughly 209,000 U.S. consumers and “certain dispute documents with personal identifying information for approximately 182,000 U.S. consumers.”
In addition, the company said it identified unauthorized access to “limited personal information for certain UK and Canadian residents,” and that it would work with regulators in those countries to determine next steps.
“This is clearly a disappointing event for our company, and one that strikes at the heart of who we are and what we do. I apologize to consumers and our business customers for the concern and frustration this causes,” said Chairman and Chief Executive Officer Richard F. Smith in a statement released to the media, along with a video message. “We pride ourselves on being a leader in managing and protecting data, and we are conducting a thorough review of our overall security operations.”
Equifax said the attackers were able to break into the company’s systems by exploiting an application vulnerability to gain access to certain files. It did not say which application or which vulnerability was the source of the breach.
Equifax has set up a Web site — https://www.equifaxsecurity2017.com — that anyone concerned can visit to see if they may be impacted by the breach. The site also lets consumers enroll in TrustedID Premier, a 3-bureau credit monitoring service (Equifax, Experian and Trans Union) which also is operated by Equifax.
According to Equifax, when you begin, you will be asked to provide your last name and the last six digits of your Social Security number. Based on that information, you will receive a message indicating whether your personal information may have been impacted by this incident. Regardless of whether your information may have been impacted, the company says it will provide everyone the option to enroll in TrustedID Premier. The offer ends Nov. 21, 2017.
At time of publication, the Trustedid.com site Equifax is promoting for free credit monitoring services was only intermittently available, likely because of the high volume of traffic following today’s announcement.
As many readers here have shared in the comments already, the site Equifax has available for people to see whether they were impacted by the breach may not actually tell you whether you were affected. When I entered the last six digits of my SSN and my last name, the site threw a “system unavailable” page, asking me to try again later.
When I tried again later, I received a notice stating my enrollment date for TrustedID Premier is Sept. 13, 2017, but it asked me to return again on or after that date to enroll. The message implied but didn’t say I was impacted.
Maybe Equifax simply isn’t ready to handle everyone in America asking for credit protection all at once, but this could be seen as a ploy by the company assuming that many people simply won’t return again after news of the breach slips off of the front page.
Update, 11:40 p.m. ET: At a reader’s suggestion, I used a made-up last name and the last six digits of my Social Security number: The system returned the same response: Come back on Sept. 13. It’s difficult to tell if the site is just broken or if there is something more sinister going on here.
Also, perhaps because the site is so new and/or because there was a problem with one of the site’s SSL certificates, some browsers may be throwing a cert error when the site tries to load. This is the message that OpenDNS users are seeing right now if they try to visit www.equifaxsecurity2017.com:
Several readers who have taken my advice and placed security freezes (also called a credit freeze) on their file with Equifax have written in asking whether this intrusion means cybercriminals could also be in possession of the unique PIN code needed to lift the freeze.
So far, the answer seems to be “no.” Equifax was clear that its investigation is ongoing. However, in a FAQ about the breach, Equifax said it has found no evidence to date of any unauthorized activity on the company’s core consumer or commercial credit reporting databases.
I have long urged consumers to assume that all of the personal information jeopardized in this breach is already compromised and for sale many times over in the cybercrime underground (because it demonstrably is for a significant portion of Americans). One step in acting on that assumption is placing a credit freeze on one’s file with the three major credit bureaus and with Innovis — a fourth bureau which runs credit checks for many businesses but is not as widely known as the big three.
More information on the difference between credit monitoring and a security freeze (and why consumers should take full advantage of both) can be found in this story.
I have made no secret of my disdain for the practice of companies offering credit monitoring in the wake of a data breach — especially in cases where the breach only involves credit card accounts, since credit monitoring services typically only look for new account fraud and do little or nothing to prevent fraud on existing consumer credit accounts.
Credit monitoring services rarely prevent identity thieves from stealing your identity. The most you can hope for from these services is that they will alert you as soon as someone does steal your identity. Also, the services can be useful in helping victims recover from ID theft.
My advice: Sign up for credit monitoring if you can, and then freeze your credit files at the major credit bureaus (it is generally not possible to sign up for credit monitoring services after a freeze is in place). Again, advice for how to file a freeze is available here.
The fact that the breached entity (Equifax) is offering to sign consumers up for its own identity protection services strikes me as pretty rich. Typically, the way these arrangements work is the credit monitoring is free for a period of time, and then consumers are pitched on purchasing additional protection when their free coverage expires. In the case of this offering, consumers are eligible for the free service for one year.
That the intruders were able to access such a large amount of sensitive consumer data via a vulnerability in the company’s Web site suggests Equifax may have fallen behind in applying security updates to its Internet-facing Web applications. Although the attackers could have exploited an unknown flaw in those applications, I would fully expect Equifax to highlight this fact if it were true — if for no other reason than doing so might make them less culpable and appear as though this was a crime which could have been perpetrated against any company running said Web applications.
This is hardly the first time Equifax or another major credit bureau has experienced a breach impacting a significant number of Americans. In May, KrebsOnSecurity reported that fraudsters exploited lax security at Equifax’s TALX payroll division, which provides online payroll, HR and tax services.
In 2015, a breach at Experian jeopardized the personal data on at least 15 million consumers. Experian also for several months granted access to its databases to a Vietnamese man posing as a private investigator in the U.S. In reality, the guy was running an identity theft service that let cyber thieves look up personal and financial data on more than 200 million Americans.
My take on this: The credit bureaus — which make piles of money by compiling incredibly detailed dossiers on consumers and selling that information to marketers — have for the most part shown themselves to be terrible stewards of very sensitive data, and are long overdue for more oversight from regulators and lawmakers.
In a statement released this evening, Sen. Mark Warner (D-Va.) called the Equifax breach “profoundly troubling.”
“While many have perhaps become accustomed to hearing of a new data breach every few weeks, the scope of this breach – involving Social Security Numbers, birth dates, addresses, and credit card numbers of nearly half the U.S. population – raises serious questions about whether Congress should not only create a uniform data breach notification standard, but also whether Congress needs to rethink data protection policies, so that enterprises such as Equifax have fewer incentives to collect large, centralized sets of highly sensitive data like SSNs and credit card information on millions of Americans,” said Warner, who heads the bipartisan Senate Cybersecurity Caucus. “It is no exaggeration to suggest that a breach such as this – exposing highly sensitive personal and financial information central for identity management and access to credit– represents a real threat to the economic security of Americans.”
It’s unclear why Web applications tied to so much sensitive consumer data were left unpatched, but a lack of security leadership at Equifax may have been a contributing factor. Until very recently, the company was searching for someone to fill the role of vice president of cybersecurity, which according to Equifax is akin to the role of a chief information security officer (CISO).
The company appears to have announced the breach after the close of the stock market on Thursday. Shares of Equifax closed trading on the NSYE at $142.72, up almost one percent over Wednesday’s price.
This is a developing story. Updates will be added as needed.
