Stripe Developer with Security Experience

Posted 6 days ago

Summary

I am looking for an experienced Stripe developer with security experience to investigate and secure my Stripe account following a recent security incident. My business uses BookingKoala as the only integration connected to Stripe. A fraudulent connected account was created within my Stripe account, resulting in approximately $7,000 being stolen. After investigating, Stripe advised me that one of my API keys had become publicly exposed, possibly through source code exposure or another security issue. What I Need: Investigate how the Stripe API key may have been exposed. Review my BookingKoala and Stripe integration. Audit API keys, webhooks, connected accounts, and account permissions. Verify there are no remaining security vulnerabilities. Remove or secure any exposed credentials. Configure appropriate fraud prevention measures and Stripe security settings. Provide recommendations to prevent future incidents. Supply a summary of findings and actions taken. My Environment: BookingKoala is my only Stripe integration. No custom website or additional payment integrations. Stripe has confirmed that an API key was exposed. Please Include: Your experience with Stripe security incidents. Examples of similar work you have completed. Your proposed approach to investigating this issue. Estimated timeline to complete the work. Because this involves a financial loss and account security, I am looking for someone with direct experience in Stripe security and fraud prevention rather than a general web developer.
