<i>According to the indictment, the defendants exploited a vulnerability in the Apache Struts Web Framework software used by Equifax’s online dispute portal. They used this access to conduct reconnaissance of Equifax’s online dispute portal and to obtain login credentials that could be used to further navigate Equifax’s network. The defendants spent several weeks running queries to identify Equifax’s database structure and searching for sensitive, personally identifiable information within Equifax’s system. Once they accessed files of interest, the conspirators then stored the stolen information in temporary output files, compressed and divided the files, and ultimately were able to download and exfiltrate the data from Equifax’s network to computers outside the United States. In total, the attackers ran approximately 9,000 queries on Equifax’s system, obtaining names, birth dates and social security numbers for nearly half of all American citizens.</i>
