Quick search suggests that there is a *lot* of people around the globe
that receives this fragmented UDP traffic from the C block you
reported.

Have you tried contacting the site admins (abuse@corbina.net and
admin@corbina.net)?

inetnum:      83.102.166.0 - 83.102.166.255
netname:      CORBINA-TECHPRO
descr:        Techpro Company
country:      RU
admin-c:      CORB1-RIPE
tech-c:       CORB1-RIPE
status:       ASSIGNED PA
notify:       noc@corbina.net
mnt-by:       RU-CORBINA-MNT
changed:      pvr@corbina.net 20040823

I would recommend blackholing this block at border firewall.
