Then you get unpredictable garbage as the result, which is useless if your
goal (as the attacker) is to plant a trojan horse that steals encrypted data
while it is decrypted. (And of course, you cannot directly decrypt the data
either.) The only way to exfiltrate the data is to attack the system while
it is running (online).
