AS47860 - 93.175.240.0/20 - Wiskey Tango Foxtrot
My analysis: Serious and apparently long-lived bogosity, with a clear history of substantial spamming aactivity. But you be the judge. Looks to me like an unregistered RIPE AS announcing a route to a /20 worth of unregistered RIPE IPv4 space. And this didn't exactly crop up just yesterday. Looks like this has been ongoing for one hell of a long time: https://stat.ripe.net/widget/routing-history#w.resource=AS47860 Of course, it's not even nearly as much of an issue -now- as it was, say, about 1 year ago, in October of 2015, when the /20 was apparently populated by a huge boat load of snowshoe spammer domains. Sadly, Spamhaus has a bad habit of consistantly failing to ever put any helpful date information on any of its listings, otherwise I'd be able to see when -they- first noticed this absurd mess. https://www.spamhaus.org/pbl/query/PBL1626432 Anyway, it's rather annoying to me personally... and I hope I'm not the only one who feels that way... to know that this has gone mostly unnoticed for so long, that nobody within the RIPE region has ever bothered to -do- anything about it, and that the AS and the bogus route are still being announced, even as we speak. Assuming the thing remains in play, how long will be be before the spammers return to use and abuse it yet again? Maybe they were just waiting for a full year to go by so that they might have some hopes of this /20 being automatically aged off some blacklists. Regards, rfg P.S. This crap appears to be be brought to us courtesy of AS29632, NetAssist, LLC: http://new.netassist.ua/ So anyway, where are the grownups?

I had a look in my feeds, then a few global BGP LG's and well, it's not in the BGP table. In reality, it's the upstream, that feeds it in, that really needs to be penalised.

assuming accuracy of records, etc... ;-) or courtesy of both AS43659 (who was peering with and announcing the prefix to) and AS29632 (who was then accepting and announcing to its upstreams)? seems to be an interesting relationship between the two (2) of them; along with an even more interesting relationship/affiliation between AS43659 and AS57166 - and the upstream for both the ASNs is/was AS29632 (NetAssist LLC). ;-) - AS57166 UA-D2INVESTUKRAINE-AS, UA; D2 International Investment Ukraine Ltd. - AS43659 BUDREMYER-AS, UA; D2 International Investment Ukraine Ltd.

Right. An that doesn't seem to be RIPE's strong suit.
Well, yes. I tried to untangle the relationships here just by looking at bgp.he.net, but as I looked at all of the relevant pages, nothing seemed to be adding up, or even remaining consistant among all of the info that bgp.he.net was showing me. So I just shrugged, gave up, and reported the few facts that I felt sure about here. Specifically, bgp.he.net is reporting the name associated with AS47860 as "Albino, LLC", but personally, I have no idea where they are getting that name from. (And it sure doesn't look like a European style of company name... rather more American, I think.) Then I looked at the bgp.he.net connectivity graph for AS47860: http://bgp.he.net/AS47860#_graph4 This suggests that AS47860 is connected to the Internet only via AS43659, D2 International Investment Ukraine Ltd. (That AS, it seems, is currently announcing -zero- routes of its own, which seems, well, odd.) The connectivity graph for AS43659 is here: http://bgp.he.net/AS43659#_graph4 This seems to indicate that AS43659 is only connected to the Internet via AS29632 and that AS29632 is itself -only- connected to the Internet via AS6939. But then when I looked at the connectivity graph for AS29632 it actually appears to have -five- different IPv4 peers: http://bgp.he.net/AS29632#_graph4 But then I looked at the actual -list- of IPv4 peers of AS29632 and I see it has 121 of them! http://bgp.he.net/AS29632#_peers So, anyay, bottom line, there are clearly things about how bgp.he.net draws connectivity graphs that I don't actually undetrstand. That's OK. I don't need to understand any of that in order to understand that AS47860 is a bogus unregistered AS which is, and which has been, apparently, for some long time, announcing a route (93.175.240.0/20) to unregistered RIPE IPv4 space. Sadly, announcing of bogons is not uncommon, so I wouldn't even have mentioned this if it hadn't been for the fact that historical passive DNS data indicate quite clearly that at least one snowshoe spammer was using that IPv4 space at about this time last year.

It's not so much a questions on RIPE's strong suit, but more the LIRs, that don't keep their info updated. RIPE only updates the basic data, to match it the contract data, but they're quite adament about updated data, if you want further allocations, which now sort of again is ... void.
I reckon .. but this is a guestimate, that the AS and prefix probably was allocated to that company in the past, but either their contract never was finalised or their contract was cancelled by one of the parties. So that might have been the name that "used" to be in the whois database for that prefix and ASN, but now isn't anymore, if the entity has ceased to exist. That could also be the reason, why the prefix and ASN have been seen historically. Either way ... that's a guestimate, but a very plausable one. Only somebody inside RIPE would be able to shed more light into, what actually happened. If they're actually permitted (could be prevented by data protection).
