“We did not apart appraise Equifax’s admonition aegis controls or the accomplish the aggregation took to abode articular factors that contributed to the abortive accomplishing of those controls,” GAO says. Instead, the independent, detached agency that conducts investigations for Congress says it analyzed affidavit about the aperture and additionally interviewed individuals at Equifax’s three better federal customers: the Internal Revenue Service, the Social Aegis Administration and the United States Postal Service.
The U.S. Computer Emergency Readiness Aggregation in March 2017 issued an active that all Apache Struts implementations should be anon patched. Equifax says it broadcast this apprehension to its systems administrators.

Equifax has additionally said that a accepted browse conducted a anniversary later, which searched for accepted vulnerabilities central its network, had bootless to banderole the blemish in the Struts accomplishing that ran its online altercation aperture (see Equifax’s Colossal Error: Not Patching Apache Struts Flaw).
Equifax had a aegis accessory that accustomed it to audit arrangement traffic, but it wasn’t alive because a agenda affidavit it appropriate had expired. “The affidavit had asleep about 10 months afore the aperture occurred, acceptation that encrypted cartage was not actuality inspected throughout that period,” GAO says. “As a result, during that period, the antagonist was able to run commands and aish baseborn abstracts over an encrypted affiliation afterwards detection.”
Equifax said it had bootless to abstract its databases on altered arrangement segments (see Solve Old Aegis Problems First).
As a result, already the attackers breached Equifax’s network, they were able to ability dozens of added databases. “The abridgement of analysis accustomed the attackers to accretion admission to added databases absolute PII, and, in accession to an asleep certificate, accustomed the attackers to auspiciously aish ample amounts of PII afterwards triggering an alarm,” GAO says.
Equifax was autumn admission accreditation acclimated by its administrators in an unencrypted format, aback able convenance would accept been to alone abundance such admonition in a defended form, finer with admission belted appliance multifactor authentication.
“The attackers acquired admission to a database that absolute unencrypted accreditation for accessing added databases, such as usernames and passwords,” GAO says. “This enabled the intruders to run queries on those added databases.”
Equifax had no restrictions in abode on database queries. As a result, the antagonist was able “to assassinate about 9,000 such queries – abounding added than would be bare for accustomed operations” aback exfiltrating the data, the GAO says.
Although not included in the GAO’s account of problems basement the Equifax breach, abounding aegis experts accept said that Equifax’s accommodation to use Apache Struts contributed to its problems.
Last month, the accessible antecedent Apache Struts 2 action appear an amend that included a appliance for a analytical vulnerability that attackers could alien accomplishment to booty abounding ascendancy of the appliance (see Apache Issues Emergency Struts Appliance to Fix Analytical Flaw).
In the deathwatch of the vulnerability report, assorted admonition aegis experts again advancing calls for organizations to stop appliance Struts.
“My admonition would be to drift to a altered technology stack. I’ve managed abundant incidents area Struts was the accessible basic that enabled crooked admission to the basal server,” adventure acknowledgment able David Stubley, who active Edinburgh-based aegis testing close and consultancy 7 Elements, told Admonition Aegis Media Group (see Apache Issues Emergency Struts Appliance to Fix Analytical Flaw).
One year afterwards Equifax apparent its massive breach, what has afflicted for the acclaim bureau, which continues to aggregate admonition on added than 800 actor individuals and over 88 actor businesses worldwide?
The Customer Financial Aegis Agency and the Federal Trade Commission, which as GAO addendum “have authoritative and administration ascendancy over customer advertisement agencies,” launched investigations into the aperture in September 2017, and these accept yet to conclude, GAO says.
But in February, account letters appropriate that the CFPB had put its Equifax analysis on ice and scaled aback its broader acclaim agency probes.
In May, meanwhile, the FTC assassin advocate Andrew Smith to run its Agency of Customer Protection. While Smith had ahead formed at the FTC, he best afresh formed for a law close that represented Equifax, and he testified afore the Senate aftermost year on account of the acclaim bureau. He has promised to recuse himself from any investigations that absorb companies for which he has worked.
On the Capitol Hill front, probes by Congress into Equifax, and added broadly into how acclaim bureaus handle PII, accept led to no new customer protections (see Cynic’s Guide to the Equifax Breach: Nothing Will Change).
In June, however, Equifax accomplished a autonomous accord adjustment with cyberbanking regulators in eight states – Alabama, California, Georgia, Maine, Massachusetts, New York, North Carolina and Texas – acute that it put specific abstracts aegis enhancements in place. By acknowledging with the accord order, Equifax will abstain accompaniment fines. The acclaim agency said it had already put abounding of the new requirements in place.
