Countermeasures Applicable for Cyberattack Steganographic Techniques

The purpose of the article is defining of main countermeasures for steganographic techniques usage in cyberattacks, comprising the development of a steganalysis tool as an example of one of the ways. Research methods: steganography in cyberattacks usage scenario analysis; steganalysis methods and available security tests review; image steganalysis software tool development; experimental evaluation of the developed tool. The result obtained: main directions of countermeasures for cyberattack steganographic techniques were formulated in the article. Image complex steganalysis software tool using a neural network to LSB insertion detection in an object has been developed. The results of the developed tool were evaluated. The study reveals directions for further researches and main applications of the study’s results, in particular, for improving DLP and SIEM solutions. The scientific novelty of the article is countermeasures for steganographic mechanisms as cyberattack techniques research. In the article proposed a steganalysis scenario based on several analysis methods combined usage.
