the ones having a looking-glass sending regexp commands to a cisco
router should disable it ASAP.
Some specific regexp simply crash the router.
the regexp is available upon request (I will only answer to people I
know)

I think I already had read about this somewhere else in the last
few weeks.
Ok, found it (did not find it in the Bugtraq or Full-Discolsure
mailing lists),
Could you check if you see any prefix on this path ? ^1299_15600
Thanks
Pascal

works (of course we prefer the direct peering via SwissIX):
#sh ip bgp regexp ^1299_15600_
Network Next Hop Metric LocPrf Weight Path
* 62.204.96.0/19 213.248.96.45 90
Please contact me offlist. I couldn't get hold of anyone at #ix or
#swinog, unfortunately.
It's a GeoIP issue we would like to resolve and concerns 217.110.0.0/15.
Thanks,
Fredy

Sounds like the same thing as the late 1990s. sho ip bgp regexp stuff
caused a reboot.
