  1. - Stage 3 (ROP payload 2):
  2. The second payload is composed by another ROP chain and data.
  3. It creates two userland threads (each one with it's own ROP chain), that take care of leaking kernel pointers (by issuing devctl commands to "sdstor0:") and breaking the userland sandbox (by exploiting sceNet functions).

  791. - Stage 4 (kernel ROP):
  792. The second ROP payload prepares the stage for a kernel attack.
  793. After it's done, another ROP chain should be starting on the kernel side.
  794. This chain relies on kernel pointers that were leaked during the second payload's execution and is built beforehand.
  795. The data portion of the chain is additionally obfuscated/encrypted with kernel-only functions.
  796.  
  797. To further reverse the exploit, one must dump the target kernel modules, rebuild the kernel ROP and deobfuscate/decrypt the data region.
