Summary
A cybersecurity researcher details a tale of how a caffeine-induced GraphQL daydream led to a successful penetration test against a major eCommerce company.
After discovering many exposed GraphQL endpoints, he realised that the APIs were not properly configured, permitting unauthenticated access and manipulations of data.
He used GraphQL to alter existing product listings, inject malicious HTML, and redirect users to phishing sites.
With almost no downtime, the researcher was able to replicate a successful ‘package hijack’ attack, diverting goods and stealing sensitive information in the process.
The eCommerce firm was notified and swiftly secured their GraphQL endpoints, reinforcing the importance of authentication and authorisation on public-facing APIs.
The article goes into great detail about the technical steps and technologies used in the attack, giving businesses and security professionals pointers on how to safeguard against such threats.
