KrebsOnSecurity has long maintained that the 2017 breach at Equifax was not the work of financially-motivated identity thieves, as there has been exactly zero evidence to date that anything close to the size of the data cache stolen from that incident has shown up for sale in the cybercrime underground.
However, readers should understand that there are countless other companies with access to SSN, DOB and other information crooks need to apply for credit in your name that get hacked all the time, and that this data on a great many Americans is already for sale across various cybercrime bazaars.
Readers also should know that while identity theft protection services of the kind offered by Equifax and other companies may alert you if crooks open a new line of credit in your name, these services generally do nothing to stop that identity theft from taking place. ID theft protection services are most useful in helping people recover from such crimes.
