## Firmware Integrity
|
|
|
|
The **custom firmware and/or compiled binaries can be uploaded to exploit integrity or signature verification flaws**. The following steps can be followed for backdoor bind shell compilation:
|
|
|
|
1. The firmware can be extracted using firmware-mod-kit (FMK).
|
|
2. The target firmware architecture and endianness should be identified.
|
|
3. A cross compiler can be built using Buildroot or other suitable methods for the environment.
|
|
4. The backdoor can be built using the cross compiler.
|
|
5. The backdoor can be copied to the extracted firmware /usr/bin directory.
|
|
6. The appropriate QEMU binary can be copied to the extracted firmware rootfs.
|
|
7. The backdoor can be emulated using chroot and QEMU.
|
|
8. The backdoor can be accessed via netcat.
|
|
9. The QEMU binary should be removed from the extracted firmware rootfs.
|
|
10. The modified firmware can be repackaged using FMK.
|
|
11. The backdoored firmware can be tested by emulating it with firmware analysis toolkit (FAT) and connecting to the target backdoor IP and port using netcat.
|
|
|
|
If a root shell has already been obtained through dynamic analysis, bootloader manipulation, or hardware security testing, precompiled malicious binaries such as implants or reverse shells can be executed. Automated payload/implant tools like the Metasploit framework and 'msfvenom' can be leveraged using the following steps:
|
|
|
|
1. The target firmware architecture and endianness should be identified.
|
|
2. Msfvenom can be used to specify the target payload, attacker host IP, listening port number, filetype, architecture, platform, and the output file.
|
|
3. The payload can be transferred to the compromised device and ensured that it has execution permissions.
|
|
4. Metasploit can be prepared to handle incoming requests by starting msfconsole and configuring the settings according to the payload.
|
|
5. The meterpreter reverse shell can be executed on the compromised device.
