I've seen this post... I didn't test so I'm not sure if this is true:

Will there be a fix for PtokaX. Any suggestions to prevent this by using LUA scripts?
It is true. It is exploit in DC++ core. I don't know when i will be able to release PtokaX with fix. But it is simple to fix that with script. Simply check if $ConnectToMe ans $Search commands contains valid ip:port ;)
