Introduction

The rapid advancement of technology and the proliferation of internet-connected devices have given rise to a myriad of cybersecurity threats. These threats are not only increasing in number but also in sophistication. Cyber adversaries are continually evolving their tactics, techniques, and procedures (TTPs) to exploit vulnerabilities and achieve their malicious objectives. Understanding these TTPs is crucial for developing effective cybersecurity strategies. This white paper provides a comprehensive overview of the attack vectors in cybersecurity, focusing on the various techniques employed by adversaries from reconnaissance to impact.
