Alice's system runs twо аpplicаtiоns, Online Bаnking (B) and Pirated Game (G), оn the operating system Doors which is the trusted computing base or TCB. Doors runs on the underlying hardware. Assume each application runs as a separate process and application B has access to sensitive data that Alice wants to secure against various types of threats. Consider the following four cases and answer if an attacker could gain access to Alice's sensitive data from application B in each case. In addition to a yes/no answer, provide a brief justification for your answer. Only application G is compromised. The TCB and the hardware remain trusted in this case. (1+1 pts.) The attacker is able to compromise the TCB by exploiting a vulnerability in the OS that impacts its correctness. (1+2 pts.) The attacker is able to compromise application G and is able to inject code into it that exploits a Rowhammer like memory hardware vulnerability to tamper with the TCB. (1+2 pts.) A firmware vulnerability leads to successful exploitation of the hardware. (1+1 pts.)
