Breach Database / Phished Data via CERT Poland

Yes — Phished Data via CERT Poland was breached.

What happened

In August 2023, CERT Poland observed a phishing campaign that collected credentials from 68k victims. The campaign collected email addresses and passwords via a phishing email masquerading as a purchase order confirmation. CERT Poland identified a further 202 other phishing campaigns operating on the same C2 server, which has now been dismantled.

What data was exposed

What to do right now

  1. Change your password for this service now. And change it anywhere you reused the same password — attackers try leaked passwords on other sites within hours ("credential stuffing").
  2. Turn on two-factor authentication. Even a leaked password is useless against an account protected by a second factor. Prefer an authenticator app over SMS.
  3. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  4. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  5. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
