What is Cobalt Strike 4.4?

Cobalt Strike 4.4 is a software that combines a graphical user interface (GUI) with a command-line interface (CLI) to provide a full-featured remote access tool (RAT) that can be used for various offensive security purposes. It is designed to help security professionals conduct realistic and sophisticated cyberattacks against their own or their clients' networks, systems, and applications.

Cobalt Strike 4.4 is based on the open-source framework Metasploit, which is widely used for exploiting vulnerabilities and delivering payloads. However, Cobalt Strike 4.4 extends Metasploit's capabilities by adding its own proprietary features, such as:

• Beacon: This is the core component of Cobalt Strike 4.4. It is a lightweight and stealthy implant that can be injected into a target system and communicate with the team server (the central control point of the attack). Beacon can perform various tasks, such as executing commands, uploading and downloading files, pivoting through the network, spawning shells, injecting DLLs, logging keystrokes, capturing screenshots, and more.

• Malleable C2: This is a feature that allows you to customize the appearance and behavior of Beacon's communication with the team server. You can use Malleable C2 profiles to mimic legitimate network traffic or protocols, such as HTTP, HTTPS, DNS, SMB, or SMTP. This can help you evade detection by network defenders and security products.

• Aggressor Script: This is a scripting language that allows you to automate and extend Cobalt Strike 4.4's functionality. You can use Aggressor Script to write your own modules, plugins, or scripts that can interact with Beacon or the team server. You can also use Aggressor Script to integrate Cobalt Strike 4.4 with other tools or frameworks.

• Kits: These are collections of tools or resources that can enhance Cobalt Strike 4.4's capabilities or performance. For example, there are kits for artifact generation (to create obfuscated payloads), mimikatz (to dump credentials), sleep (to delay Beacon's execution), and more.

What are the benefits of Cobalt Strike 4.4?

Using Cobalt Strike 4.4 can provide you with several advantages, such as:

• Realism: Cobalt Strike 4.4 can help you simulate real-world attack scenarios and techniques that are used by advanced persistent threat (APT) groups or nation-state actors. You can use Cobalt Strike 4.4 to conduct reconnaissance, exploit vulnerabilities, establish persistence, move laterally, escalate privileges, exfiltrate data, and more.

• Versatility: Cobalt Strike 4.4 can be used for various purposes and scenarios, such as penetration testing, red teaming, adversary emulation, incident response, threat hunting, malware analysis, training, or research. You can use Cobalt Strike 4.4 to target different platforms (Windows, Linux, macOS), architectures (x86, x64), or environments (cloud, on-premises).

• Flexibility: Cobalt Strike 4.4 can be customized and adapted to your needs and preferences. You can use Malleable C2 profiles to change Beacon's communication parameters or indicators of compromise (IOCs). You can use Aggressor Script to create your own modules or plugins or integrate with other tools or frameworks. You can also use kits to add new features or improve existing ones.

• Ease of use: Cobalt Strike 4.4 has a user-friendly GUI that allows you to manage your attack infrastructure and operations from a single interface. You can also use the CLI to execute commands or scripts directly on the team server or on a Beacon session.

How to use Cobalt Strike 4.4?

Once you have installed and launched Cobalt Strike 4.4, you can use it to perform various tasks, such as:

• Launching a Beacon session: This is the first step to establish access to a target system. You need to create a payload using Cobalt Strike 4.4's artifact kit or other tools, and deliver it to the target system using an exploit or other methods. Once the payload runs on the target system, it will inject Beacon into memory and communicate with your team server.

• Executing commands: Once you have a Beacon session, you can use it to execute commands on the target system, such as listing files and directories, creating or deleting files or folders, running programs, modifying registry keys or values, etc.

• Uploading and downloading files: You can also use Beacon to upload files from your system to the target system, or download files from the target system to your system.

• Pivoting through the network: You can use Beacon to pivot through the target network and access other systems that are not directly reachable from your team server. You can use various techniques, such as port forwarding, SOCKS proxy, reverse port forwarding, etc.

• Spawning shells: You can use Beacon to spawn various types of shells on the target system, such as cmd.exe, PowerShell, Meterpreter, etc.

• Injecting DLLs: You can use Beacon to inject DLLs into processes on the target system, such as mimikatz.dll, which can be used to dump credentials from memory.

• Logging keystrokes: You can use Beacon to log keystrokes on the target system and capture user input.

• Capturing screenshots: You can use Beacon to capture screenshots of the target system and view what the user is seeing.

• And more: You can use Beacon to perform many other tasks on the target system, such as escalating privileges, establishing persistence, exfiltrating data, etc.
