Currently, software protection methods based on the use of cryptographic algorithms are widely used. Regarding the effectiveness of protection of this class, I would like to cite the opinion of Chris Kaspersky, author of the book "The Technique and philosophy of hacker attacks": "These defenses look unbreakable. They "look" because developers do not take into account the difference between theoretical models and practical implementation... a lot of the cryptosystems used are unreliable, and almost all are vulnerable to one degree or another"[20, p. 30].

Vulnerability of cryptographic protection systems

chntpw is a utility for viewing some information and changing user passwords in the Windows NT/2000, XP, Vista, 7 SAM user database file, usually located in \WINDOWS\system32\config\SAM in the Windows file system. In Kali Linux, it is already installed natively.

Any website is vulnerable to intruders and is not immune from hacking. It is not necessary that the purpose of virtual criminals is to steal data or access user accounts. The site can be used as a repository of their information, usually illegal. With the help of a stolen resource, they can spread spam, engage in mining, and extortion.

How to protect a website from hacking and viruses

The better the site, the more attacks there are on it. Unfortunately, this is the harsh reality of the Internet.

We don't want to brag, this dependence is reflected in our products: customers often complain about attacks; but we prevent them in time by building protection against hacking at the stage of its development.

6 WAYS TO PROTECT YOUR SITE FROM HACKING

Thefatrat is a massive tool that allows you to bypass most antivirus programs.

A simple tool to create a backdoor to bypass AV and a lightweight tool for a post-exploitation attack such as a browser attack, DLL.

This tool compiles malware with a popular payload, and then the compiled malware can be run on Windows, Android, Mac.

Mobile operators receive a lot of data and metadata, which can be used to learn a lot about the life of an individual subscriber. And by understanding how this data is processed and stored, you will be able to track the entire chain of information passing from the call to debiting money. If we talk about the internal intruder model, then the possibilities are even more enormous, because data protection is not at all part of the tasks of the mobile operator's pre-billing systems.

Definition of hacking
Hacking is a set of actions to identify and then exploit vulnerabilities in a computer system or network, usually in order to gain unauthorized access to user or company data. Hacking is not always the result of malicious actions, but the term itself has acquired a negative connotation due to its frequent use in the context of cybercrime.

What is hacking and how to prevent it?

Now let's focus on a radical way to open the encryption key or password.

          Let's assume that the author avoided common implementation errors and did not provide the cracker with either the key (password) in plain text, or comparison commands and explicit conditional transitions. In addition, the password is chosen according to all the rules and cannot be selected "manually". In this case, the hacker will try to iterate through all possible passwords.

A complete brute force attack

Once again, the vast majority of the protections used in practice are based precisely on a key comparison. In fact, both non-standard formatting parameters and other key disk parameters, as well as passwords, registration numbers (codes), and the number of program launches, and the time of free use of the software, and the counter of installed copies, and many other characteristics are essentially the key to protection.

SOFTWARE PROTECTION HACKING TECHNOLOGIES

There are several ways to bypass the protection using the key disk. The easiest way is to copy the key disk. Recall that most traditional methods are designed to make it impossible for a standard copier program to create a copy of a key disk.
