Hello,
where should I report fraudulent AS(Autonomous Systems), which are announcing mainly cybercriminal hosting subnetworks?
Depending on what type of "cyber crime"[1] you are referring to, where the victims are located, where the "service" is operated or offered, and what your own jurisdiction is - my advice would be to report to your local Law Enforcement and/or Telekom Regulator and/or the National CERT or CSIRT[2]. It can - in some countries/regions - also be useful to report to transit and/or up-stream ISPs, and/or to their National CERTs.
sorry if i'm posting to wrong maillist.
Cheers,
