Credentials are Still King: Leaked Credentials, Data Breaches and Dark Web Markets

This article explains the threat posed by infostealer malware and leaked credentials, describing tiers of leaked credentials (from large breach dumps to fresh stealer logs containing cookies), the use of combolists, techniques for bypassing MFA (including OTP bots and SIM-swapping), and recommended mitigations such as credential monitoring, password managers, reduced session TTLs, and authenticator apps. It cites telemetry (millions of stealer logs and over 14 billion leaked credentials monitored by the vendor) to illustrate scale and distribution via dark web and illicit marketplaces.
