Root Cause

• Unauthorized system access detected: Unusual login attempts, IP anomalies, or compromised credentials suggest a security breach.

• Use of compromised API keys or tokens: Insecure or leaked authentication credentials were detected during the transaction attempt.

• Violation of payment gateway security policies: Non-compliance with required encryption standards, tokenization, or API security guidelines triggered the violation.

• Fraudulent payment method application detected: The bank/payment processor identified inconsistencies or suspicious details in the payment method.

Troubleshooting and Solutions

• Review and rotate your API keys, tokens, and payment gateway credentials if a compromise is suspected.

• Immediately suspend or lock affected accounts and payment processing until the issue is investigated.

• Notify internal security teams to analyze logs, trace unauthorized access, and assess potential data breaches.

• Collaborate with your payment gateway provider to identify and resolve any vulnerabilities and ensure compliance with security protocols.

• Advise the customer to change their account passwords and enable additional security measures, such as multi-factor authentication.
