 TITLE: How Reusing Passwords Can Lead to Online Attacks CONTENT: What Is Credential Stuffing?\n----------------------------\nCredential stuffing occurs when criminals use large numbers of stolen email addresses and passwords from one site—usually as part of a data breach—to attempt to access other sites through high-volume attacks. That high volume would seem to make it easy for companies to see a visible spike in traffic, but criminals are smarter than that: They know how to make the attempts blend into normal traffic making it difficult for companies to notice anything unusual. And that's when your data gets used against you.\n\"The tools used to automate the attacks easily evade common defenses,\" says Chris Ryan, Experian senior fraud solutions business consultant. \"Organizations that think they are protected are much more vulnerable than they realize.\" END
