An exploit is one of the ways that attackers can easily gain access to a user's confidential information.
At its core, an exploit is nothing more than a piece of code. Sometimes a piece of software or just a set of commands can act as an exploit. Their whole point is that they look for vulnerabilities in the user's computer, and if they find them, they will try to attack the system. The purpose of such actions can be different - from seizing control over the system to disrupting its performance (DOS attacks).
Types of exploits
There are two types of exploits: remote and local. As you might guess from the name, the remote exploit works directly through the network and exploits and looks for a security vulnerability without any prior access to it. The local exploit works already on the user's system itself and this already requires access. For the most part, a local exploit is used to gain superuser rights. In addition, exploits are subdivided directly into the search for vulnerabilities in a specific part of the computer (its software). The most popular varieties are: exploits for operating systems, for application software, browsers used by the user, for Internet sites and products.
How to use an exploit?
To exploit the exploit, an attacker would need an interpreter such as Perl. Then, in the command line of the operating system, the path to this interpreter and to the saved file, which contains the spit code, is indicated. As a result, the attacker connects to the server of some website, obtains IP addresses, and with their help connects to the computer of an unsuspecting user.
The exploit can be used in a slightly different way. To do this, you first need to scan the server for errors. This is done using special scanners, for example, LANguard Network Security Scanner. Then the IP address of the computer to which you want to access is entered, after which you need to wait until a list of all possible vulnerabilities appears. When the vulnerability is found, you can download a special exploit on the Internet that works with the vulnerability found and use it to inject it into the user's computer.
To protect your PC from such malicious programs, you need to use antiviruses with modern databases, a firewall and a firewall. These programs will maximize the protection of your PC from various external threats.
