Icebox : Virtual Machine Introspection, Tracing & Debugging

Icebox is a Virtual Machine Introspection solution that enable you to stealthily trace and debug any process (kernel or user). It’s based on project Winbagility.

Getting Started

Some sample have been written in samples folder.

You can build them with these instructions after you installed the requirements.

If your using a Windows guest you might want to set the environement variable _NT_SYMBOL_PATH to a folder that contains your guest’s pdb. Please note that icebox setup will fail if it does not find your guest’s kernel’s pdb.

vm_resume:
vm_resume just pause then resume your VM.

cd icebox/bin/$ARCH/
./vm_resume
<vm_name>

nt_writefile:
nt_writefile breaks when a process calls ntdll!NtWriteFile, and dumps what’s written in a file on your host in the current directory.

cd icebox/bin/$ARCH/ .
/nt_writefile
<vm_name> <process_name>

heapsan:
heapsan breaks ntdll memory allocations from a process and add padding before & after every pointer. It is still incomplete and doesn’t do any checks yet.

cd icebox/bin/$ARCH/
./heapsan
<vm_name> <process_name>

wireshark:
wireshark breaks when ndis driver reads or sends network packets and creates a wireshark trace (.pcapng). Each packet sent is associated to a callstack from kernel land to userland if necessary.

cd icebox/bin/$ARCH/
./wireshark
<name> <path_to_capture_file>
