Proactively Assess and Validate Defenses.

Gain access to the most influential red teaming software on the market.

  • Simulate a quiet long-term embedded actor with persistent post-exploitation agents capable of maintaining a low profile
  • Test a blue team’s detection capabilities by emulating a loud attacker using malleable C2 profiles
  • Change network indicators to look like different malware and replicate the behaviors of known advanced adversaries
  • Generate reports to provide details on the attack timeline and indicators from red team activity

The Impacts of Red Teaming

Red teams with effective tools play a critical role in mitigating threats:

  • The Financial Reality: The average cost of a data breach is $4.88 million.
  • Your Objective: Assess your defenses and highlight security weaknesses that lead to these high-impact incidents.
  • Post-Exploitation Insights: Understanding the attacker’s potential post-compromise reveals the full scope of damage a breach could cause, demonstrating the true risk to better inform security strategies.

Cobalt Strike Features

Beacon is Cobalt Strike’s signature post-exploitation payload, designed to emulate advanced persistent threat tactics.

It can be deployed through various methods like executables, documents, or exploits, and communicates with the red team server using methods that enable it to keep a low-profile.

Once deployed, Beacon can gather information, execute arbitrary commands, deploy additional payloads, move laterally, and more.

Further post-exploitation features can be added using Beacon Object Files (BOF), compiled C programs that can execute within a Beacon process.

Cobalt Strike provides red teams with significant flexibility and the ability to adapt communication strategies. This enables persistent access while minimizing the risk of detection. Options include:

  • Malleable C2 Profiles: Mask Beacon activity or mimic real-world threat actors, enhancing stealth.
  • HTTP/HTTPS Egress: Uses standard web protocols to blend in with normal internet traffic.
  • DNS Egress: Offering a more covert channel that can bypass some firewalls
  • Peer-to-Peer Beacon Connections (TCP & SMB): Facilitates low-profile communication between compromised internal systems for lateral movement.

We highly value feedback from our community. Cobalt Strike’s development is heavily influenced by the insights and experiences of our users. We actively monitor community discussions, and incorporate user suggestions into our development roadmap.

The Cobalt Strike Arsenal Kit offers a collection of tools that provide a customizable foundation for replicating the techniques of advanced threat actors.

Operators can leverage these tools directory or tailor them specifically to meet specific objectives. The Arsenal Kit includes:

  • Sleep Mask Kit: Hides Beacon in memory while it sleeps.
  • Mutator Kit: Employs an LLVM mutator to disrupt in-memory YARA scanning of sleep masks.
  • User-Defined Reflective Loaders: Provides custom reflective loaders capable of implementing individualized tradecraft.

Cobalt Strike offers different reporting options to provide details about each engagement:

Cobalt Strike’s browser pivoting allows red teams to easily execute a simulation of a man-in-the-browser attack.

It enables operators to use their own web browser to interact with web applications and resources as if they were directly using the compromised machine. This hijacks the target’s logged-in browser, bypassing two-factor authentication.

In addition to post-exploitation activities, Cobalt Strike offers features for initial access. This tool provides options for email templates, custom messages, and social engineering package attachments.

Once sent, users can monitor key metrics like email opens and link click, identifying specific users who have potentially triggered the initial compromise.
