Live Cybersecurity Webinar — Deconstructing Cobalt Strike

Organizations' cybersecurity capabilities have improved over the past decade, mostly out of necessity. As their defenses get better, so do the methods, tactics, and techniques malicious actors devise to penetrate their environments.

Instead of the standard virus or trojan, attackers today will deploy a variety of tools and methods to infiltrate an organization’s environment and attack it from the inside.

In an interesting twist of fate, one of the tools organizations have used to audit and improve their defenses has also become a popular tool attackers use to infiltrate. Cobalt Strike is an Adversary Simulation and Red Team Operations tool that allows organizations to simulate advanced attacks and test their security stacks in a close-to-real-world simulation.

A new research webinar from XDR provider Cynet (register here) offers a better look at Cobalt Strike. The webinar, led by Cyber Operations Analyst for the Cynet MDR Team Yuval Fischer, will take a deep dive into the threat.

As a simulation, it is impressive in its capabilities, and it’s prized for being highly customizable. All these traits have also made it an effective attack tool for actual malicious actors. Cobalt Strike is a C2 server that offers highly sophisticated and easy-to-use features, and the past year has seen a huge jump in the number of recorded Cobalt Strike attacks in the wild. In fact, a study by Recorded Future’s Insikt Group found that Cobalt Strike was the most commonly deployed C2 server in malicious attacks.

One of the biggest reasons Cobalt Strike has become so widespread is its various capabilities, which include:

• Reconnaissance on client-side software usage, as well as version vulnerabilities
• A variety of attack packages that include social engineering, trojans, and masquerading tools
• Collaboration tools that let group host share data with a group of attackers
• Post exploitation tools to deploy scripts, log keystrokes and execute other payloads
• Covert communication tools that let teams modify network indicators on the go
• Browser pivoting to circumvent

Additionally, Cobalt Strike uses Beacon, a powerful delivery mechanism that can be transmitted over various protocols, and hide by modifying its network signature, emulating other types of malware, and even masquerading as legitimate traffic.

Even so, Cobalt Strike is not undetectable. However, it requires a variety of techniques to detect it properly. This includes things like examining default TLS certificates, searching for open ports, And performing HTTP requests to find non-existent pages. Even then, most organizations require advanced tools actually to defend against Cobalt Strike..

The new research webinar dives deeper into Cobalt Strike. It does so by exploring a few areas:

• The basics of Cobalt Strike as an attack tool. This includes breaking down how it works, what makes it so effective, and how malicious actors have modified, customized, and upgraded it to become more dangerous.
• Instances in the wild. More than any theoretical research, live case studies provide the greatest insights into how Cobalt Strike operates and succeeds in penetrating organizations’ defenses.
• A deeper dive into Cobalt Strike’s capabilities and deployment tools. The webinar will also dive deeper into Cobalt Strike’s different functionalities, how they’re deployed, and what they actually do.
• How organizations can defend against Cobalt Strike. Finally, the webinar will touch on the ways organizations can detect and defend against Cobalt Strike, and how they can mitigate the impact of a successful initial infiltration.
