MrRa [10]

Sounds like you are talking about Grid computing. You can also say cloud computing since that is the buzz words nowadays, but cloud computing is a very general statement.

An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The at

Anni [7]

"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.

Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.

⇒ There are two kinds of Buffer overflow attacks such as:

<u>Stack-based</u> - It will become more popular to use such memory, as well as that's only available during implementation of any code.
<u>Heap-based</u> - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.

Thus we can say that the correct answer is a Buffer overflow.

Explanation:

#include <stdio.h>

int num2 = atoi(argv[2]); // Getting num2 from user

char *fileSource = argv[3];

char *fileTarget = argv[4];

int source_fd = open(fileSource, O_RDONLY); // opening the file in read only mode

int target_fd = open(fileTarget, O_WRONLY | O_CREAT); // opening the target file in Writeonly mode if file is not found it will create

char *ch = (char *) calloc(num2+num1, sizeof(char));

stat(fileSource, &st);

if(st.st_size < (num1 + num2)){

printf("File Size is smaller than the specified bytes\n");

read(source_fd, ch, st.st_size); // reading the file upto the end

write(target_fd, ch, st.st_size); // two times writing to the file

}else{
