Experian Glitch Exposing Credit Files Lasted 47 Days

Summary: Identity thieves bypassed Experian's identity verification by editing the address in the browser URL bar at a specific point in the process, reaching any consumer's full credit report with only a name, address, date of birth, and Social Security number. Experian confirmed the weakness persisted from Nov. 9 to Dec. 26, 2022, roughly seven weeks, and notified Krebs by mail about a month after he reported it on Dec. 23.

Bottom line: The entire barrier between an identity thief and a full credit file was four data points and one URL edit, and the bureau stayed silent for a month after being told. For seven weeks, the only credential required to pull anyone's report was information already circulating in breach dumps.
