Microsoft has released its long-awaited cloud-based bug detection tool, previously code-named "Project Springfield." The Windows version became generally available, and a new Linux version became available as a preview last week. The tool, Microsoft Security Risk Detection, uses artificial intelligence to hunt down security vulnerabilities in software that is about to be released. Microsoft Security Risk Detection will help developers do fuzz testing, said David Molnar, the Microsoft researcher in charge of the group that developed the tool.
