Harnessing GPUs - Building Better Browser Based Botnets

Explore the potential of browser-based botnets utilizing GPU power in this Black Hat Europe 2013 conference talk. Delve into the misconceptions surrounding the security of encryption keys and password hashes, and learn how attackers can leverage browser technology to create powerful, cost-effective botnets. Discover the methods for building GPU-accelerated botnets using XSS, HTML5, and cache poisoning techniques. Examine the capabilities of WebGL, NaCL, Flash, and WebCL in harnessing GPU computing power within web browsers across various platforms. Analyze the impact, cost, stealth requirements, and portability of these advanced botnets, and gain insights into their optimal architecture and performance metrics. Consider the current and future implications of this technology for attackers, including their potential to break higher-entropy keys and compromise sensitive data across a wide range of devices.
