FindObjects-BOF is a Cobalt Strike Beacon Object File (BOF) project which uses direct system calls to enumerate processes for specific modules or process handles.
What Is This Repository For?
Why Do I Need This?
Utilizing direct systems calls via inline assembly in BOF code provides a more opsec safe way of interacting with the system. Using direct system calls avoids AV/EDR software intercepting user-mode API calls.
FindModule
bof can be used to identify processes which have a certain module loaded, for example the .NET runtime clr.dll
or the winhttp.dll
module. This information can be used to select a more opsec safe spawnto candidate when using Cobalt Strike’s execute-assembly
or before injecting an exfill beacon shellcode using the shinject
command.FindProcHandle
bof can be used to identify processes with a specific process handle in use, for example processes using a handle to the lsass.exe
process. If there’s a process within the system with a lsass.exe
process handle, we could use this existing process/handle to read or write memory without opening a new process handle. This bypasses certain AV/EDR’s capabilities of detecting and blocking LSASS process/memory access.How Do I Set This Up?
We will not supply compiled binaries. You will have to do this yourself:
sudo port install mingw-w64
).make
command to compile the Beacon object file.Script Manager
to load the FindObjects.cna script.FindProcHandle
or FindModule
command with the required parameters (e.g. module or process name).Overview WhatsMyName is a free, community-driven OSINT tool designed to identify where a username exists…
