Just-In-Time (JIT) Spraying
Just-In-Time (JIT) spraying is a technique used by hackers to exploit vulnerabilities in web browsers and other software that use just-in-time compilation. JIT compilation is a process where the software compiles code at runtime, which can improve performance.
JIT spraying involves flooding the memory of the software with small pieces of code that can be assembled into a larger exploit. This is done by exploiting flaws in the software’s memory allocation process, which can allow the attacker to execute arbitrary code.
When the vulnerable software performs JIT compilation on the attacker’s code, the exploit is assembled and executed. This can allow the attacker to gain control of the vulnerable system.
To protect against JIT spraying attacks, software developers need to implement secure memory allocation processes and other security measures. Users can also protect themselves by keeping their software up-to-date and using security software, such as antivirus and firewalls.
