No stealer infection found — your credentials were not caught in infostealer logs.
What to do now
Change the password on the affected account immediately — and anywhere you reused it.
Enable two-factor authentication (2FA) everywhere; prefer an authenticator app over SMS.
Use a unique, strong password for every account (a password manager helps).
If passwords or session cookies were in stealer logs, log out all sessions and re-secure recovery email/phone.
Watch for phishing: attackers know your leaked data and will pose as trusted services.
Check your accounts regularly — new breaches surface over time.
