Learn how Java ClassLoaders can be exploited to create malicious "evil twin" instances in this 29-minute conference talk that demonstrates advanced Java security vulnerabilities. Explore the mechanics of ClassLoader manipulation and understand how attackers can leverage different ClassLoader contexts to create seemingly identical but potentially dangerous object instances. Discover the technical details behind ClassLoader isolation bypasses, examine real-world scenarios where evil twin attacks could occur, and gain insights into defensive programming practices to protect Java applications from these sophisticated exploitation techniques. Master the underlying principles of Java's class loading mechanism while understanding how security boundaries can be circumvented through clever ClassLoader manipulation strategies.
