Security & Privacy

All work is performed based on client authorization or publicly available APIs. We describe protocol analysis and reverse engineering in compliance with laws and platform policies.

1) Information to Provide

1. Target App name / package (already provided: pl.pkobp.iko)
2. Integration scenarios and priority features (e.g., transactions export, BLIK, NFC)
3. Testing accounts or sandbox credentials and any real account sample with authorization
4. Need for compliance docs, NDA, or audit reports

2) Our Execution Steps

1. Protocol capture and endpoint identification (HTTPS/XHR paths, requests/responses)
2. Authorization modeling (Token flow, session refresh, two-factor)
3. API wrapping & SDK development (including error handling, retries)
4. Compliance review & delivery (docs, test cases, compliance guidance)

3) Compliance & Security Notes

• All protocol analyses follow lawful, compliant principles; where necessary, obtain test APIs via official channels or sign access agreements with banks.
• Avoid storing sensitive credentials long-term; provide token lifecycle management and auto-refresh strategies.
• Provide detailed validation logs and attestation for signature fields, NFC and card management operations.
• Recommend testing in a bank/ regulator sandbox before production
