I think, if timed correctly, you could persist a transaction with malicious content in quite a lot of mempool.dat files for only a few satoshis. The transaction would stay in the mempool.dat file until the bitcoin node restarts, which quite possible could be a full release cycle.

Should the mempool.dat file be encrypted/XORed?
