+
+The [Rust Community Team](https://community.rs) is pleased to announce the
+first annual Underhanded Rust Contest, inspired by the [Underhanded
+C](http://www.underhanded-c.org/) and [Underhanded
+Crypto](https://underhandedcrypto.com/) contests. Our goal with
+[Rust](https://www.rust-lang.org/) is to make it easy to write trustworthy
+low-level software that is resistant to accidental security vulnerabilities,
+though less often challenged has been Rust's ability to protect against
+*deliberate* vulnerabilities in the face of scrutiny. This challenge is
+designed to put our language and [the broader Rust
+ecosystem](https://crates.io/) to the test, to help us learn where our blind
+spots are and what needs to be done to address them. In short, we want you to
+break our stuff using reasonable, easy-to-read code. Can you write 100% safe
+Rust that hides a logic bug, or hide an exploit in
+[unsafe](https://doc.rust-lang.org/book/unsafe.html) Rust that passes an audit?
+Now's your chance!
+
