Analysis of cyber attacks such as APT (Advanced Persistent Threat) and ransomware

Abstract

In the information society, cyber attacks launched upon the information technology infrastructure are increasingly diversified and complex. Cybercriminals or black hat hackers use a wide range of techniques, tactics and procedures to compromise computer systems. APT and ransomware attacks are two cyber security threats that many companies and government institutions face. Ransomware is a medium complexity attack, while APT is a high complexity cyber attack. The emergence of certain hybrid malicious programs (computer worm-ransomware) and the diversification of attack vectors represent new challenges for specialists and organizations.
