Abstract
Advanced persistent threats pose a significant challenge for blue teams as they apply various attacks over prolonged periods, impeding event correlation and their detection. In this work, we leverage various diverse attack scenarios to assess the efficacy of EDRs against detecting and preventing APTs. Our results indicate that there is still a lot of room for improvement as state-of-the-art EDRs fail to prevent and log the bulk of the attacks that are reported in this work. Additionally, we discuss methods to tamper with the telemetry providers of EDRs, allowing an adversary to perform a more stealth attack.
Highlights
Cyber attacks are constantly evolving in both sophistication and scale, reaching such an extent that the World Economic Forum considers it the second most threatening risk for global commerce over the decade [1]
Since the experience and the capacity of the blue team depends on multiple factors which are beyond the scope of our work, in this study, we focus on the telemetry of the endpoint detection and response (EDR), the significance that they label events, and whether they blocked some actions
Throughout this work, we went through a series of attack vectors used by advanced threat actors to infiltrate organizations
Summary
Cyber attacks are constantly evolving in both sophistication and scale, reaching such an extent that the World Economic Forum considers it the second most threatening risk for global commerce over the decade [1]. The threat actor would try to exploit a single exploit or mechanism to compromise as many hosts as possible and try to immediately monetize the abuse of the stored information and resources as soon as possible. In APT attacks, the threat actor opts to keep a low profile, exploiting more complex intrusion methods through various attack vectors and prolong the control of the compromised hosts. This control may span several years, as numerous such incidents have shown
