nyms being attacked by malware

I've noticed a very high increase of incoming virii and malicious code of various sorts to one of my nyms. Since the nym is not used anywhere publically I really wonder if these are deliberate attacks to try to compromise the machines of people using nyms to protect their identity. Is this something that's a known strategy somehow? Obviously it could also be that the nym was previously used by someone else online and that's partly why it would be interesting to hear other's comments on this.
