Format string attacks:Occurs when the submitted data of an input string is evaluated as a command by the application. In this way, the attacker could execute code, read the stack, or cause a segmentation fault in the running application, causing new behaviors that could compromise the security ...
Heap-based buffer overflows: A heap-based attack is more difficult to carry out than the stack-based approach. It involves the attack flooding a program’s memory space beyond the memory it uses for current runtime operations. Format string attack: A format string exploit takes place when an...
During an enumeration attack, hackers are looking for unique server responses confirming the validity of a submitted credential. The most obvious response is a field authentication message after a web form submission. To explain this process, we will use an example of a username enumeration attack ...
Moreover, phishing is often used to gain a foothold in corporate or governmental networks as a part of a larger attack, such as anadvanced persistent threat(APT) event. In this latter scenario, employees arecompromisedin order to bypass security perimeters, distribute malware inside a closed envi...
This attack (in all its forms) is mitigated by not responding to requests from unknown parties in which money has to be given to receive something in return. If it sounds too good to be true, it probably is. A simple Google search on the theme of the request or some of the text its...
An attack surface is different from an attack vector. An attack vector is the method - the way for attackers to enter a network or a system. For example, common attack vectors include social engineering attacks, credential theft, vulnerability exploits, and insufficient protection against insider ...
A denial-of-service (DoS) attack is designed to prevent online services from working efficiently, also known as abrute-force attack. It is typically caused by an attacker flooding a website with huge amounts of traffic or requests, in an attempt to overwhelm its systems and take them offlin...
A cyber attack is a set of actions performed by threat actors, who try to gain unauthorized access, steal data or cause damage to various computing systems.
Another variation on spear phishing attacks is clone phishing. In this attack, targets are presented with a copy (or “clone”) of a legitimate message they had received earlier, but with specific changes the attacker has made in an attempt to ensnare the target (e.g. malicious attachments,...
Format strings attack Attackers change the way an application flows by misusing string formatting library functions, like printf and sprintf, to access and manipulate other memory spaces. Unicode overflow attacks These attacks exploit the greater memory required to store a string inUnicodeformat than ...
