I know about those two servers
bibi.hamachi.cc [64.34.106.33]
aali.hamachi.cc [64.34.106.7]
So block this
Maybe there are more serves but I think all are from 64.34.106.x range so maybe u can block whole range (if some important services not works you can iron it out later) or check you firewall (router) log what servers within this range are accessed via himachi

Hope that helps, rate if it does
