The method of basic static analysis of harmful software is considered, which is based on searching and analyzing the term in files that are built using the PE (Portable Executable) format. The method of basic static analysis of malicious software is considered, which is based on the analysis of headers of executable files, and dynamic libraries, which are built using the PE format. An extended static analysis method is considered, which, in addition to analyzing the term and file headers, uses disassembly of executable files and dynamic libraries and further analysis of the resulting assembler text.
In order to penetrate the operating system, cybercriminals use specialized software and network attacks. Moreover, a network attack does not have to be massive and widespread. To penetrate a particular operating system, for example, you can take advantage of vulnerabilities in both the operating system itself and the software that is installed on such an operating system. Moreover, successful attacks of this type are often made quiet and unobtrusive.
To prevent hacker attacks that are accompanied by hidden software installation and to minimize harm from such attacks, it is necessary to apply adequate countermeasures in a timely manner. One of the most widespread and easy methods of fighting hackers is the timely updating of software, virus databases, installation and configuration of a firewall.
Everything related to software updates is a reaction to threats that have already been identified. Therefore, the software update does not provide protection against the threats just identified. That is why the signatures of virus databases are created as a result of the analysis of the detected virus programs. Antivirus software also uses program behavior analysis to enhance the detection of malware. But even in this case, it is necessary to analyze the disassembled text of malicious software to identify new types of abnormal activity. Therefore, the analysis of malicious software is an urgent task and determines the direction of the study.
