The Breach Risk Index (BRI) is a proprietary 0–100 score rating how dangerous a breach is right now, based on how recently the data has been circulating on the dark web and how valuable it is to attackers.
Breach Summary
Polish Credentials is a circulating aggregated credential dataset (about 1,200,000 records where counted), combining email/password pairs from infostealer logs and prior breaches rather than a single-company breach.

About Polish Credentials
Polish Credentials is not a breached company but an aggregated collection of credentials assembled from many sources (infostealer logs and/or prior breaches) and distributed in the cybercrime ecosystem.
Why They Hold Your Data
As an aggregated credential set, it contains email addresses and passwords (and sometimes usernames) drawn from many separate sources rather than one organization's records.
Recent Developments
Polish Credentials circulates as a credential dataset used to seed credential-stuffing and account-takeover tooling.

Breach Impact
As an aggregation, its significance is enabling large-scale credential-stuffing across unrelated services, not harm to one company.
Exploitation & Downstream Threats
• Credential stuffing against reused passwords across other platforms | • Targeted phishing campaigns using exposed email addresses
Principal Risk Advisory
What this means for a principal
A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- Reset any reused passwords and enable MFA on email first, then financial accounts.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping: cross-reference the exposed identifiers against broker-available data to size and prioritize the principal's wider footprint.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
