Software developers looking to kickstart (or simply brag about) their security have a common trick up their sleeve: give away prizes to successful crackers. Redact is trying just such a strategy with its Secure Messenger app for iOS. It's offering £10,000 ($15,482) to anyone who can visit London and successfully intercept an encrypted message delivered through the company's peer-based, PIN-to-PIN communication system. Entrants have until June 1st to prove that they're worthy of making an attempt. Redact has more reason to hope we lose beyond its pride and a big fat check, however -- it wants approval for handling the UK government's secure data, and it wouldn't hurt to have proof that the app design is airtight. If you're convinced that it's all just bluster, you can challenge the company yourself at the source link.
