Vulnerabilities in build systems, secrets in source code: developer environments are an attack target Tim Anderson Wed 27 Jan 2021 // 19:31 UTC Share Copy Developer site Stack Overflow has published details of a breach dating back to May 2019, finding evidence that an intruder in its systems made extensive use of Stack Overflow itself to determine how to make the next move. At the time, the company reported that an unauthorised person had logged into its development system and escalated their access to the production version of stackoverflow.com. The source code for the site as well as the names, IP addresses and email addresses of 184 users was stolen, but not the databases which contain the content of the site and that of its customers.
