Cogent & FDCServers: Knowingly aiding and abetting fraud and theft?
by Ronald F. Guilmette 06 Sep '19

06 Sep '19

Few of you here probably know about this, but nearly a week ago now an article appeared in South Africa's largest and most popular online tech publication, MyBroadband.co.za. It detailed many, but certainly not all of the results of my multi-month investigation of a massive and ongoing fraud involving the theft of large numbers of large (generally /16 or larger) abandoned legacy blocks, taken from the AFRINIC region and beyond: https://mybroadband.co.za/news/internet/318205-the-big-south-african-ip-add… For various editorial reasons, the article that was published actually downplayed the magnitude of the of the thefts quite dramatically. The totality of the IPv4 space that has been stolen or squatted, primarily but not exclusively, from South African companies and South African national goverment agencies and departments is actually at least 5x bigger than what was reported in the MyBroadband.co.za article. The overwhelming majority of this stolen and squatted IPv4 space has been helpfully routed by Cogent (AS174), to their customer, FDCServers of Chicago, and then on to the prefered destinations of a certain Mr. Elad Cohen of Israel, and his company Netstyle Atarim, Ltd. (I have saved traceroutes up the wazoo that prove the involvement of FDCServers, in particular, in all of this.) Mr. Cohen has been exceptionally prolific in his IPv4 theft and squatting activities, basically grabbing everything that wasn't nailed down, both within the AFRINIC region and also within the APNIC region. In order to try to legitimize all of these thefts and squats, Mr. Cohen created quite a sizable number of fradulent route: objects within the Merit/RADB data base which, as most here should already know, has essentially zero authentication of any kind before it allows J. Random Luser to add pretty much any any route: object he wants to the RADB. Here's a full listing of all of Mr. Cohen's RADB route: objects as they existed as recently as August 17th: https://pastebin.com/raw/ZNgNuvtt And here is the short summary version showing just all of the prefixes/CIDRs that Mr. Cohen was effectively claiming rights and/or title to as of that same date: https://pastebin.com/raw/4LTaCg5R Plese do note the numerous blocks of size /16 or greater. The bottom line is that this one tiny little Israeli company was effectively claiming rights to a total of no fewer than 1,015,808 IPv4 addresses as of August 17th, 2019. (Not too shabby for one lone guy who teaches programming classes as a side job!) Vitrually all of the space is "legacy" IPv4 space, and generally consists of blocks having sizes of /16 or larger. Some of Mr. Cohen claims in his RADB entries are as humorous as they are pathetically fradulent. For example, Mr. Cohen has effectively claimed rights to 139.44.0.0/16 which unambiguously belongs to the Port Authority of the City of Melbourne, Australia. But hell! That's merely city property! Mr. Cohen's limitless appetite for other people's IPv4 space is more vividly on display in his claims to ownerhip over the 168.198.0.0/16 block, which actually belongs to the Department of Finance of the Australian national government. And I haven't even mentioned yet another of Mr. Cohen volumous IPv4 acqusitions, the 165.25.0.0/16 block, which he did not see fit to create an RADB entry for, but which he's been squatting on for for quite some time now, quite clearly with the aid and assistance of both Cogent and FDCServers. That one belongs to th City of Cape Town, South Africa. That city's engineers have been struggling to regain control of their block back from Cogent, from FDCServers, and from Mr. Cohen for some time now. I know because I've personally spoken to them about it. Cogent, in its infinite wisdom, is continuing to fight the city for control over property that clearly and righfully belongs to the City of Cape Town, even as we speak: https://drive.google.com/file/d/1ytRj1CtuVhDa0eGu4BT-oEz593y5EwJa/view When asked for LOAs attesting to his legitimate authority to route at least a few of these blocks, Mr. Cohen has produced blatantly forged documents, many of which appeared in the MyBroadband.co.za story. And when I say "blatant" that's a gross understatement. Any half-way decent forger would consider these documents an embarrasment. The documents all bear identical signatures, and identical and vaguely official looking stamps, and purport to actually be sales reciepts attesting to the alleged purchases, by Mr. Cohen's offshore Seychelles Islands shell company, Afri Holdings, Ltd., of various /16 blocks from a mysterious company called Afrivestment, Ltd., which may actually exist in some faraway galaxy, or in Mr. Cohen's active imagination, but which both Google and OpenCorporates.com seem to agree exists exactly noplace on this planet. Here are the manufactured LOAs supplied by Mr. Cohen: https://drive.google.com/file/d/1hVjmR6u0ANltuXtZ-Kng8io-EGFyevTR/view https://drive.google.com/file/d/1x_44_H5hkcFLhEwpkwfFoR5PJUyXHzxJ/view https://drive.google.com/file/d/1yQyqn4q_f3bt-wDVoN1FzbXf1k58DXtK/view Recently, Cohen started to move some, but not all, of his stolen and squatted IPv4 blocks off of Cogent/FDCServers and onto a friendly little bullet-proof hosting company in the Netherlands named IP Volume, Inc. (AS202425) and/or to its several sister networks, e.g. AS204655 - Novogara Ltd., all of which, coincidently, just happen to be owned by the exact same pair of Dutch gentlemen who previously owned the notorious Ecatel, follwed by the notorious Quasi Networks. (IP Volume, Inc. appears to have intherited all or nearly all of its legitimately assigned IP space from its predecessor entities, Ecatel and Quasi Networks.) Despite these relocations, many of Mr. Cohen's stolen and squatted blocks are still helpfully being routed to Mr. Cohen's preferred desitnations by his good friends at Cogent and FDCServers, even as we speak. The current set of such routes that Cogent is maintaining, at the moment, apparently on behalf of their customer, Mr. Cohen, consists of the prefixes listed here: https://pastebin.com/raw/EA3xJVLF When I noticed two days ago that all of these routes were still up I was deeply confused. Did both Cogent and FDCServrs not get the memo?? Do they not know yet that Cohen is stealing stuff, left, right, and sideways? Did nobody even tell them about the MyBroadband.co.za article which was published this past Sunday? I decided that it was incumbant upon me to find out. Thus, more that 48 hours ago now I sent the following polite but firm inquiry to Cogent, and a separate nearly identical one directly to the CEO of FDCServers, Mr. Petr Kral (petr(at)fdcservers.net) https://pastebin.com/raw/ztipqE96 A full forty eight hours later, I have received no reply whatsoever from either Cogent or FDCServers, not even a "Go pound sand" type of response. More importantly, most of the stolen IPv4 space that I called out, very specifically, to both Cogent and FDCservers two+ days ago now is still being routed by Cogent/FDCservers to their fun-loving and, I'm sure, promptly paying customer, Mr. Cohen. If neither Cogent nor FDCServers still do not know now that Mr. Cohen is a crook, and that he has glommed onto quite a lot of stolen and squatted IPv4 space... which they have been helpfully routing for him, no doubt in exchange for some handsome payments... then I am foreced to say that it appears to be a reasonable conclusion that it must be because neither Cogent nor FDCServers really wants to know what sort of a character Cohen is, or what he has been up to, specifically with their ongoing and material assistance. But you all be the judges. What does it look like to you? Regards, rfg

Art and Tech is madness
by Kasper Adel 06 Sep '19

06 Sep '19

In SPRING a time when segment and routing had no mismatch, a time when isis and ospf ate a forbidden encap, all they had to do was forward bgp like its hot, but crazy flapping doesnt leave any real LDP without some real FSM check, My dynamic unnumbered neighbor. Suddenly, Out of order, an AS is overridden, we see frames dropping, we sniff a bit and it turns out, sfps are burning, we are in a place right now where ping and pong are jittery, their latency is tested, they cant strengthen their icmp bond with a warm bfd message, how can they keep everyone in ACK, safe from teardown and dampening, with this kind of ixp relationship??! but oh admin, we know forwarding works in its own mysterious ways. We are left with two non rfc compliant scavengers, bastard 802.1ah fools in a leaky yet shaped, buffer display of some runts and nimbles, and a giant too. They start their life of a packet, leaving one interface to a neighbor, from an adjacency to a peer, an endless loop, its a prefix hijack, but as they move from one stack to another, finding their way through a tunnel of memory failures and RMAs, one hell of an LSP ride, through firewall horrors and MTU mismatches, leaving behind, a sea of syslog messages and snmp alarms. Anyway, Their ttl expired and one funny access list abruptly denies them life, sending them to Null0, where they can be peacefully discarded. Thats what tech does to yeh

Cat 5 hurricane -- How are the Bahamas doing?
by Sean Donelan 06 Sep '19

06 Sep '19

It is too early for damage assessments. BTC, local Bahama telecommunications company, is reporting widespread power outages, and intermittent mobile and wireline telephone service. The Abaco Islands in northern Bahamas seem to be taking the worst of it. Network measurements sites are reporting less than 6% reachability in Hope Town, Bahamas. Other parts of Bahamas have less than 50% reachability.

Spam due to new ARIN allocation
by Tim Burke 05 Sep '19

05 Sep '19

We recently received a new ASN from ARIN - you know what that means... the sales vultures come out to play! So far, it has resulted in spam from Cogent (which is, of course, to be expected), and now another company called "CapCon Networks" - http://www.capconnetworks.com. As far as I am aware, this practice is against ARIN's Terms of Use. Is it worth reporting to ARIN, or perhaps it's worth creating a List of People To Never Do Business With™, complete with these jokers, and other vultures that engage in similar tactics? Regards, Tim Burke tim(a)burke.us

The e2e paper is by far one of the closest things we have to network canon and its reasoning is exceptionally simple and compelling. Yet, these are arguments, not laws. Even the original authors have revisited and questioned the original ideas. The paper also says something about needing a great deal of system implementation detail to intelligently make the choice of where to place functions. I like pointing that out, because it seems people often miss this part in the paper where the only form of the word intelligence is ever used in the paper. Note, I'm not agreeing or disagreeing with any particular position about multihoming in this thread, just trying to argue that the e2e paper is a lot more nuanced than is often presented in debates especially since it has often been used to support opposing views. :-) John
