Recent code reuse attacks are able to circumvent various address space layout randomization (ASLR) techniques by exploiting memory disclosure vulnerabilities. To mitigate sophisticated code reuse attacks, we proposed a light-weight virtual machine, RERANZ, which deploys a novel continuous binary code re-randomization to mitigate memory disclosure oriented attacks. In order to meet security and performance goals, costly code randomization operations are outsourced to a separate process, called the “shuffling process”. The shuffling process continuously flushed the old code and replaced it with a fine-grained randomized code variant. RERANZ repeats the process each time an adversary might obtain the information and upload a payload. Our performance evaluation shows that RERANZ Virtual Machine incurs a very low performance overhead. The security evaluation shows that RERANZ successfully protect the Nginx web server against the Blind-ROP attack.
