MMMJTAG is an abstraction library meant to make debugging windows apps/drivers using Intel DCI through OpenIPC easier.
It also aims to evade anti-debugging. Some potential uses off of the top of my head are:
- Vulnerability research in software that doesn't like to be debugged
- Antimalware
- Actual malware that involves kernel components
- Anticheat
- DRM
- etcetc...
- Bypassing bitlocker in cases where a PIN isn't in use, only a TPM
- On most mobos, JTAG can be enabled without disturbing the TPM state. The PCRs will still match their expected values
- Exploration of VTL1
