A couple of weeks ago, the IP-squatters in Saint Petersburg, Russia hijacked routed address space of the Italian National Institute of Nuclear Physics (Istituto Nazionale di Fisica Nucleare), a popular target of theirs. Pictured below are the timelines of AS198596’s originations of 192.135.33.0/24 and 192.84.129.0/24, which are more-specific hijacks of 192.135.32.0/23 and 192.84.128.0/20, respectively — both normally originated by AS137 (GARR, the Italian Research & Education Network).
