An advanced persistent threat (APT) is a stealthy threat actor, typically a state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period. [1] [2] In recent times, the term may also refer to non-state-sponsored groups conducting large-scale targeted intrusions for specific ...
Mass assignment is a computer vulnerability where an active record pattern in a web application is abused to modify data items that the user should not normally be allowed to access such as password, granted permissions, or administrator status.
Sample Attack Code; If it is possible to demonstrate the exploit code, this section provides a location to store the demonstration code. In some cases, such as a Denial of Service attack, specific code may not be possible. However, in Overflow, and Cross Site Scripting type attacks, sample code would be very useful. Existing Exploits
Here, the code under attack is the code that is trying to check the parameter, the very code that might have been trying to validate the parameter to defend against an attack. [20] Any function that can be used to compose and run a shell command is a potential vehicle for launching a shell injection attack.
The United States and Britain filed charges and imposed sanctions on a company and individuals tied to a Chinese state-backed hacking group named APT31 that they allege engaged in a sweeping cyber ...
PMD is able to detect flaws or possible flaws in source code, like: Bugs—Empty try/catch/finally/switch blocks. Dead code—Unused local variables, parameters and private methods. Empty if/while statements. Overcomplicated expressions—Unnecessary if statements, for loops that could be while loops.
Many software products have experienced problems with old legacy source code; for example: Legacy code may not have been designed under a defensive programming initiative, and might therefore be of much lower quality than newly designed source code. Legacy code may have been written and tested under conditions which no longer apply.
