LLMs Power Up Hackers: Exploiting Trapped COM Objects with AI
Large Language Models (LLMs) are rapidly changing the landscape of cybersecurity, and not just for defenders. Recent research highlights how LLMs are being leveraged to accelerate offensive research and development, specifically in identifying and exploiting previously obscure vulnerabilities. One such area is the exploitation of "trapped COM objects," a technique that allows attackers to gain control of systems in unexpected ways.

What are Trapped COM Objects?
COM (Component Object Model) is a Microsoft technology that allows different software components to communicate with each other. "Trapped COM objects" refer to a specific class of vulnerabilities where an attacker can manipulate the creation and interaction of COM objects to execute arbitrary code. Security researcher James Forshaw originally detailed this bug class, highlighting how seemingly harmless COM objects could be leveraged for malicious purposes.
How LLMs Accelerate the Exploitation
LLMs are proving to be valuable tools in offensive R&D by automating and accelerating the process of identifying and exploiting these trapped COM objects. Here's how:
- Identifying Vulnerable Objects: LLMs can analyze large codebases and documentation to identify potential COM objects that are susceptible to exploitation.
- Generating Exploitation Code: Once a vulnerable object is identified, LLMs can generate proof-of-concept (PoC) code to demonstrate the exploit.
- Automating the Attack: LLMs can automate the entire exploitation process, from identifying the vulnerability to executing the attack.
A recent case study demonstrated how AI-assisted exploration uncovered viable alternatives within the “trapped COM object” bug class. The generated proof-of-concept code follows a consistent attack pattern:
- Instantiate the target COM object remotely.
- Obtain the IDispatch interface.
- Call GetTypeInfo to navigate to the containing type library.
- Locate hijackable classes like StdFont.
- Use ITypeInfo.CreateInstance to create trapped objects.
- Access .NET reflection through the compromised System.Object.
The Implications
The use of LLMs in offensive R&D has significant implications for cybersecurity. It lowers the barrier to entry for attackers, allowing them to discover and exploit vulnerabilities more quickly and efficiently. This means that organizations need to be more vigilant than ever in protecting their systems from attack.
Key Takeaways
- LLMs are being used to accelerate offensive R&D.
- Trapped COM object exploitation is one area where LLMs are proving to be effective.
- This trend lowers the barrier to entry for attackers and increases the need for proactive security measures.
