WHO'S SPAMMING YOU? Top 60 Proxy-Hijacker-Friendly Nets 2003-08-06
by Ronald F. Guilmette 07 Aug '03

07 Aug '03

What follows below is a volume-ranked list of the most prolific /24 IP address blocks with respect to open proxy hijacking activity over the past 2 days. These ranking are based on data collected by my extensive open proxy honeypot network for the 48 hour period from 5 PM Pacific Daylight Time, August 4th, 2003 through 5 PM Pacific Daylight Time August 6th, 2003. Some brief commentary material follows the list. If you or someone you know owns or operates any of the networks listed below, please contact me off-list so that we may arange for the timely cremation of the relevant criminal spammers and open proxy hijackers, and the scattering of their ashes in some suitable garbage dump. (Note that mass open proxy hijacking of the kind being originated from all of the /24 blocks listed below is quite clearly a criminal act within these United States. The criminals doing this stuff are violating the federal Computer Fraud and Abuse Act in so many dif- ferent ways it isn't even funny.) ** NOTICE ** I will provide the specific IP addresses that are actually engaged in the proxy hijacking activities within each of these blocks upon request. What I positively WILL NOT DO is to provide detailed log files from my proxy honeypot machines to any party, PERIOD. (DON'T EVEN ASK unless you enjoy being verbally abused.) Doing so would only tend to give the spammers info that they could use to deduce the locations of my honeypot machines, which they would then carefully avoid.) I will provide date/time stamps to relevant network admini- strators, but ONLY in cases involving clearly dynamic IP addresses. 1. 38.112.197 cogentco.com - daicahosting.com/daica.com (Tampa, FL) 2. 66.44.228 savanti.net (Tucson, AZ) 3. 202.177.23 kdd.net.hk (Hong Kong) 4. 66.205.223 cetnetworks.com - smartmailhosting.com (New Orleans, LA) 5. 38.114.11 cogentco.com - tailoredservers.com (Frisco, TX) 6. 66.44.231 savanti.net (Tucson, AZ) 7. 209.50.253 servint.com (McLean, VA) 8. 66.111.39 unitedcolo.com aka sagonet.com (San Francisco, CA) 9. 38.114.3 cogentco.com - tailoredservers.com (Frisco, TX) 10. 66.250.125 cogentco.com - applicationx.net (Alpha, NJ) 11. 166.90.206 level3.com - ?Alan Ralsky?

Some of you may have seen those prior lists and thus may be all too familiar with many of the networks listed above, especially in the topmost few positions. My comments about specific networks follow: cogentco.com: What can I say? The facts speak for themselves. This is now the #1 most criminal-friendly network on the Internet. They have been hosting the criminal open proxy hijackers that are attached to the net via the following downstream customers for a long while now, and they know exactly what's going on here, because I told them, several times. I can only infer that they prefer to keep on accepting money from criminals: daicahosting.com/daica.com (previously throw off 2 other networks) tailoredservers.com (totally unreachable & bullet-proof) applicationx.net (caught red-handed with a web page full of proxies) infinology.com sagonet.com (Has some blocks suspiciously SWIPed to Cogentco.) Cogent's `tailoredservers.com' customer is THE perfect false front for spamming activities. No phone numbers on the web site. False/disconnected phone number in their WHOIS, and no need for them to ever take any call from any disgruntled folks whose servers they (or their customers) have hijacked. Level3: These people have been hosting a ``mystery'' major-league criminal proxy hijacker in their 166.90.206/24 block for MONTHS, and if they don't know that then it is only because they don't want to know. (I've already told them myself, several times.) And they were informed that this criminal activity was going on from their network all the way back as far as March: http://news.spamcop.net/pipermail/spamcop-help/2003-March/028053.html Note that the criminal in question is located someplace in the Detroit area and has been rumored to most likely be none other than Alan Ralsky, known mega-spammer who bragged in this article: http://www.freep.com/money/tech/mwend22_20021122.htm that he's got 20 spam pumping machines in his basement going 24/7. And the evidence suggests that he does, and that they are all busy hijacking other people's poorly secured proxies, all courtesy of the kind folks at Level3. Note: The SpamHaus Project describes Ralsky as a "convicted fraudster" and has an extensive file on him: http://www.spamhaus.org/rokso/search.lasso?evidencefile=1290 Oh! And lest I forget, Level3 also continues to provide bandwidth to the criminal open proxy hijackers that are working out of the notorious spam-friendly outfit called `CandidHosting'. sagonet.com: Sagonet.com and its west coast subsidiary, unitedcolo, seem to have more criminal open proxy hijackers per square inch than any other network or company on the net. A few days ago, they had no fewer than 9 different /24s listed in my Top 60 list of open proxy hijacking origi- nation points. I've seen some signs in the past 24 hours that they may perhaps finally be getting their act together, but then again, maybe not. Time will tell. (I have been told that the owner is just plain greedy, and that he does really understand why spam is bad.) savanti.net: Finally got kicked off sterlingnetwork.net within the past 24 hours. Will be looking for a new home, I'm sure. BE ON THE LOOKOUT FOR THESE GUYS as they wander around, in search of new connectivity. (This is as least the second strike for them, or so I'm told. They were kicked off another network before sterlingnetwork.net.) kdd.net.hk: Seems to be approaching the density of lead. No response whatsoever to hijacking reports. The lights are on but nobody's home. Does anybody know anybody who can explain to these people what proxy hijacking is and why it's bad? servint.com: Sounds familiar. These guys have been in trouble before, haven't they? nutnbut.net: Could be renamed to Nothin' But /dev/null P.S. My special thanks to verio.net, rr.com, algx.net, and jet2.net, all of whom seem to be able to kill these blasted proxy hijackers just about as fast as I can report them.

ATT.net private blacklist
by Ben Browning 06 Aug '03

06 Aug '03

Greetings, We have somehow fallen into the private blackhole list maintained by att.net at blacklist.mail.ops.worldnet.att.net I have tried for the last two days to approach ATT via phone and email with no response whatsoever. abuse(a)att.net, abuse_rbl(a)att.net, and several addresses pulled from ARIN and NetSol lookups have not yielded any response. The calls I have placed have resulted in me leaving a message that was never returned and several instances of "Try abuse_rbl(a)att.net". None of these are working at all. On top of that, there is no page or FAQ pertaining to blacklist.mail.ops.worldnet.att.net (at least, not one that is readily apparent to myself or Google). If there are any ATT.net admins here, or someone that may have some contact information of said admins, I would appreciate an email or a call. Thanks! ~Ben --- Ben Browning <benb(a)theriver.com> The River Internet Access Co. WA Operations Manager 1-877-88-RIVER http://www.theriver.com

Real-life figures of hardware limitations
by Stefan Baltus 06 Aug '03

06 Aug '03

Dear Collegues, As network-specialists often design new networks and evaluate equipment of different vendors I can imagine that, in my own finding, more people find it hard to determine the limitations of what equipment can do in terms of maximum throughput of a certain type of interface under certain conditions, the maximum number of accounting data (such as flow-statistics) a router can really sustain, how much ATM vc's you can really terminate on a type-x router that carries x Mbit/s of traffic, etc. Most of the time, the technical specs are either over-promising, have 'sales&marketing'-type of figures or do not really apply to real-life traffic patterns. Also, it is not always possible to do real-life testing with the box, due to a number of problems that can arise (can't get hold of the box, can't generate enough traffic, can't generate traffic that is a good representation of the real-life situation, etc). I am looking for information that gives me (and, if people are willing to share, I'm willing to put all data on a publicly available website) more insight in these kind of figures. It is possible that this is already being provided on a website of somebody, but I haven't found it yet; people that have, please point me in the right direction. The goal is to assemble as much information as possible to provide the myself and everyone who wants to know with real-life information about what a certain piece of hardware can do, to complement and/or confirm the figures from the spec-sheet. Please reply off-list. I will post a summary on the list for the people that are interested. Regards, -- Stefan Baltus <stefan.baltus(a)xbn.nl> XB Networks B.V.

If they did that, how would they sell the CSS hardware? :) I would think that the closest you are going to get to that is the CSS blade for the Cat 6500's. Although, wasn't there a version of code for the 6500's that had some local director features in it awhile back? Or did you actually need a local director blade? -jay

Comcast people?
by Austad, Jay 06 Aug '03

06 Aug '03

Are there any Comcast employees here? There exists an intermittent problem on your network which occurs every night at 12:04am central time. I've pinned it down to where it lies, but everytime I call your support department, I just get someone who does not understand. In fact, one lady told me sternly "Sir, we do not have any routers." Please contact me off list and I'll shoot you the relevant info (background, traceroutes, etc). ---------------- Jay Austad Network Engineer Travelers Express / MoneyGram e: jaustad(a)temgweb.com p: 952.591.3779
