Has your domain been caught in an infostealer dump?
Enter any domain to see how many employee and customer sessions have been captured by infostealer malware — RedLine, Vidar, LummaC2 and friends. Stealer logs are the #1 initial-access vector for ransomware, so this is a fast way to check your exposure.
What this tool tells you
Employee credentials are logins captured on corporate endpoints where your domain appears as an internal app (SSO, VPN, admin consoles). These are the highest-risk entries — a single stolen employee session can give an operator direct access to internal systems and is a frequent prelude to ransomware deployment.
User (customer) credentials are logins captured on consumer machines where your domain appears as a visited website. These matter for account-takeover scenarios — attackers buy these in bulk and run credential-stuffing attacks against your login page.
What's an infostealer?
Infostealers are a class of malware — RedLine, Vidar, Raccoon, LummaC2, StealC, and dozens of other families — that harvest saved passwords, session cookies, crypto wallets and autofill data from infected endpoints. The stolen "logs" are sold on cybercrime markets and Telegram channels; ransomware operators routinely buy these to establish initial access. CISA's KEV catalog, Verizon DBIR, and Mandiant M-Trends all rank stealer-log access as a dominant root cause of major breaches.
What happens if you see a hit
Treat any non-zero employee count as an incident-response trigger. Rotate credentials for affected accounts, invalidate sessions, force MFA re-enrollment, and hunt for follow-on activity on the endpoints in question. Customer hits warrant forcing password resets for affected accounts and monitoring for credential-stuffing spikes.
Want continuous monitoring of your brand?
This is a point-in-time lookup. ServiceAlert.ai's Brand Protection product monitors your domains continuously for stealer hits, phishing impostors, typosquats, exposed secrets on GitHub, and dark-web chatter — alerting via email, Slack, Teams, or Webhook the moment something new appears. See plans.
