In January of 2021, CodeCov suffered a supply chain attack that exposed client environment variables. In the following months, the specifics of the breach and its technical applications have been thoroughly examined by the application security community to determine what went wrong and how to combat similar attacks in the future. But another interesting outcome of the breach were the insights into a slightly less glamorous topic: responsible disclosure.

In a previous blog post, we took a look at Java’s custom serialization platform and what the security implications are. And more recently, I wrote about how improvements in Java 17 can help you prevent insecure deserialization. However, nowadays, people aren’t as dependent on Java’s custom serialization, opting instead to use JSON. JSON is the most widespread format for data serialization, it is human readable and not specific to Java.

We are very excited to announce that Snyk has achieved AWS Security Competency status, further validating our commitment to security excellence in partnering with AWS!
