Your personal information is on the dark web. What happens next?

This advisory explains how personal data ends up on the dark web—via large-scale data breaches, infostealer malware-as-a-service (e.g., RedLine, Lumma), phishing enhanced by generative AI, accidental leaks from misconfigured cloud assets, and supply-chain compromises like MOVEit—and what criminals do with it (financial fraud, identity theft, session hijacking). It recommends immediate actions (change passwords, enable MFA with apps or hardware keys, sign out of sessions, contact banks, freeze cards and credit, scan for malware, report to authorities) and longer-term hygiene (limit data retention, use password managers and reputable security software, avoid storing card details, reduce broker data, use privacy tools, and monitor exposure with services such as HaveIBeenPwned).
