Tools and Exploits

• KexecDDPlus - is a Windows tool that relies on Server Silos to access the KsecDD driver directly, without having to inject code into LSASS. This capability therefore allows it to operate even on systems on which LSA Protection is enabled. For more details see Exploiting KsecDD through Server Silos .
• tpm_sniffing_pin is a simple Python PoC to retrieve the VMK through TPM Sniffing by knowing the user's PIN.
