We measure the effectiveness of Nozzle by demonstrating that it successfully detects 12 published and 2,000 synthetically generated heap-spraying exploits. We also show that even with a detection threshold set six times lower than is required to detect published malicious attacks, Nozzle reports no false positives when run over 150 popular Internet sites. Using sampling and concurrent scanning to reduce overhead, we show that the performance overhead of Nozzle is less than 7% on average. While Nozzle currently targets heap-based spraying attacks, its techniques can be applied to a more general class of attacks in which an attacker attempts to fill the address space with dangerous code objects.
