Sandboxing is a security technique that isolates an untrusted program in a restricted environment. By doing so, it limits the damage that the program can cause, even if it is compromised by malware.

There are a number of different sandbox-evasion techniques that malware can use to try to escape from a sandbox. Some of the most common include:

-Using legitimate programs to bypass the sandbox: Malware can try to abuse legitimate programs that are allowed to access the system outside of the sandbox. For example, a piece of malware could try to exploit a browser vulnerability to escape the sandbox and gain access to the underlying operating system.

-Hooking into system calls: Some sandboxes monitor system calls made by programs in order to detect and prevent malicious activity. Malware can try to hook into these system calls in order to bypass the sandbox and gain access to the underlying operating system.

-Using rootkits: Rootkits are a type of malware that can be used to hide files, processes, and other malicious activity from the operating system. This can make it difficult for sandboxes to detect and prevent malicious activity.

-Detecting the sandbox: Some malware is designed to detect when it is running in a sandbox. This allows the malware to avoid performing any malicious activity that would be detected by the sandbox.

-Escaping the sandbox: In some cases, malware may be able to escape the sandbox entirely. This could allow the malware to gain access to the underlying operating system and potentially infect other systems on the network.

Sandboxing is a valuable security technique, but it is not perfect. Malware authors are constantly finding new ways to bypass sandboxes and infect systems. It is important to keep your system and software up to date to help mitigate the risk of infection.
