Financial institutions, home automation products, and hi-tech offices have increasingly used voice fingerprinting as a method for authentication. Recent advances in machine learning have shown that text-to-speech systems can generate synthetic, high-quality audio of subjects using audio recordings of their speech. Are current techniques for audio generation enough to spoof voice authentication algorithms? We demonstrate, using freely available machine learning models and limited budget, that standard speaker recognition and voice authentication systems are indeed fooled by targeted text-to-speech attacks. We further show a method which reduces data required to perform such an attack, demonstrating that more people are at risk for voice impersonation than previously thought.

![Black Hat USA 2018 - Stop that Release, Theres a Vulnerability!
Software companies can have hundreds of software products in-market at any one time, all requiring support and security fixes with tight release timelines or no releases planned at all. At the same time, the velocity of open source vulnerabilities that rapidly become public or vulnerabilities found within internally written code can challenge the best intentions of any SDLC.
How do you prioritize publicly known vulnerabilities against internally found vulnerabilities? When do you hold a release to update that library for a critical vulnerability fix when its already slipped? How do you track unresolved vulnerabilities that are considered security debt? You ARE reviewing the security posture of your software releases, right?
As a software developer, product owner, or business leader being able to prioritize software security fixes against revenue-generating features and customer expectations is a critical function of any development team. Dealing with the reality of increased security fix pressure and expectations of immediate security fixes on tight timelines are becoming the norm.
This presentation looks at the real world process of the BlackBerry Product Security team. In partnership with product owners, developers, and senior leaders, theyve spent many years developing and refining a software defect tracking system and a risk-based release evaluation process that provides an effective software security gate. Working with readily available tools and longer-term solutions including automation, we will provide solutions attendees can take away and implement immediately.
• Tips on how to document, prioritize, tag, and track security vulnerabilities, their fixes, and how to prioritize them into release targets
• Features of common tools [JIRA, Bugzilla, and Excel] you may not know of and examples of simple automation you can use to verify ticket resolution.
• A guide to building a release review process, when to escalate to gate a release, who to inform, and how to communicate. Black Hat USA 2018 - Stop that Release, Theres a Vulnerability!](https://i.ytimg.com/vi/BxAdOKeGD7s/mqdefault.jpg)
