Your Stolen Password Is Already For Sale Somewhere In January 2024, a dataset called "Naz.API" surfaced on dark web forums containing over 70 million unique email addresses paired with plaintext passwords. The data had been harvested from credential-stealing malware installed on everyday people's computers. If
Your Employees' Passwords Are Probably Already for Sale In January 2024, researchers discovered a file called "Naz.API" circulating on dark web forums containing over 71 million unique email addresses paired with plaintext passwords — many harvested by credential-stealing malware. That's not a hypothetical. That'
In December 2024, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory warning that Russian military-linked threat actors were systematically using brute force attacks to compromise Microsoft 365 accounts across government agencies and critical infrastructure.
