Equifax isn’t the only credit-reporting behemoth with a website redirecting visitors to fake Adobe Flash updates. A security researcher from AV provider Malwarebytes said transunioncentroamerica.com, a TransUnion site serving people in Central America, is also sending visitors to the fraudulent updates and other types of malicious pages.
As Ars reported late Wednesday night, a portion of Equifax’s website was redirecting visitors to a page that was delivering fraudulent Adobe Flash updates. When clicked, the files infected visitors’ computers with adware that was detected by only three of 65 antivirus providers. On Thursday afternoon, Equifax officials said the mishap was the result of a third-party service Equifax was using to collect website-performance data and that the “vendor’s code running on an Equifax website was serving malicious content.” Equifax initially shut down the affected portion of its site, but the company has since restored it after removing the malicious content.
