Compromised Credentials

Usernames, passwords, or session tokens that attackers have obtained and can use to access accounts or systems.

Also known as stolen credentials leaked credentials exposed credentials

Compromised credentials are authentication secrets that have fallen into attacker hands through infostealer infections, phishing, database leaks, or password reuse. They are the currency of modern cybercrime. A single compromised corporate email can unlock VPN access, cloud consoles, code repositories, and SaaS admin panels.

Traditional breach notifications often arrive months after criminals already bought and sold the data. Infostealer intelligence surfaces exposures in near real time by indexing stealer logs as they appear in criminal channels. Hudson Rock lets teams search for compromised credentials tied to their domains, emails, and usernames.
