 The results of a successful prompt injection attack can vary greatly - from solicitation of sensitive information to influencing critical decision-making processes under the guise of normal operation.  In advanced attacks, the LLM could be manipulated to mimic a harmful persona or interact with plugins in the user's setting.  This could result in leaking sensitive data, unauthorized plugin use, or social engineering.  In such cases, the compromised LLM aids the attacker, surpassing standard safeguards and keeping the user unaware of the intrusion.  In these instances, the compromised LLM effectively acts as an agent for the attacker, furthering their objectives without triggering usual safeguards or alerting the end user to the intrusion
