I have a code that someone sent to me. I think it is a computer language. Sample is 149 129 147 what is it?

Answer 1

i think that it's a shell code : shellcode is a relocatable piece of machine code used as the payload in the exploitation of a software bug which typically allows an unauthorised user to communicate with the computer via the operating system's command line as a result of exploiting a vulnerability in software running on the machine. Normally stored as a null terminated string, it cannot contain null characters.

A shellcode may be used as an exploit payload, providing a cracker with command line access to a computer system with the privileges of the process that has been exploited. To avoid detection by anti-intrusion measures and to store more than one string, crackers often make use of self-decrypting code, polymorphic code and alphanumeric code.

Shellcodes can be stored in a process' memory space and subsequently executed as a result of the attacker gaining control of the program counter using vulnerabilities such as stack and heap-based buffer overflows, or format string attacks. There are various methods of controlling the program counter which vary between operating systems and processor architectures. They include but are not limited to: overwriting the return address in a stack frame, overwriting exception handlers and Windows-based shatter attacks.

There are two main methods of communicating with a compromised machine: a listening port to accept connections or a connect-back shell, the latter connects back to a predetermined address whilst the other waits for any incoming connections. The main practical difference occurs at a firewall that is configured to block connection requests for ports that do not run an authorised service, whereas outward bound connections may be assumed to be legitimate.

Answer 2

There are numerous things this could be, including a shell code. The other possiblity, if the number is 10 digits in the format you have shown, it also could coordinate to the numbers on a phone, like texting ie. when texting you press 444 568 368 means "hi I love you" hope this helps

Answer 3

Hi!

I ain't no expert in programming, but I believe it's a piece of a reversed shell code. I have, however, no idea on how to use it!

Good luck.
