AS201133
by Ronald F. Guilmette 01 Jul '16

01 Jul '16

Which LIR issued AS201133? Is this supposed to be some sort of a secret? If so, could someone please tell me where I need to go, or who I need to talk to in order to learn the secret handshake necessary to find out how this AS came into being and/or who vouches for the legitimacy and authenticity of its current owner? P.S. I've never been very good on geography, so maybe someone can straighten me out on that score also. The last time I looked, Belieze was not actually within the RIPE geographic region. Was there some rather significant continental drift while I was sleeping?

Malware/ransomware current live distribution IPs

This is an update to my earlier post today on this same topic. The list below is somewhat more complete and somewnat more up-to-date. +_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_ The various domains and IP address listed in the following file are, as we speak, acting as distribution/infection points for some sort of Javascript malware which is almost certainly a flavor of ransomware. ** FAIR WARNING *** Please use exceptional caution when browsing to any of the domains listed within the following file. Doing so with a vlunerable browser and/or from a vulnerable platform is likely to cause encryption of your entire harddrive. Such encryption may perhaps be irreversable without paying a ransom. ftp://ftp.tristatelogic.com/pub/cases/295165/20160629-1.txt I am including below the same information as is present within the above referenced file, but without the associated domain names. I do this in order to avoid having this message improperly filtered, as it might be, by some of the spam filters being used by some of the people who really should see this message. (But example malware- distribution domain names that currently resolve to the IP addresses listed below are all readily available in the above file.) Note that the domain names involved in this particular set of malware distributors are all third-level .COM domains, and that in all cases, the actual text of the first (leftmost) of the three domain name labels is irrelevant and can be replaced by any other valid domain name label because the second level domains have all been wildcarded in the DNS. The following list has been sorted numerically, based on the AS number.

Weird Packets from source ::0/64
by Max Grobecker 30 Jun '16

30 Jun '16

Hello, today I noticed that my IPv6 NTP server (intentionally public available) gets NTP packets from source network ::0/64 on the WAN interface. Source addresses are, for example: ::5cb2:92ff:fefe:9a47 ::7c04:27ff:fe6b:b26b ::8c7c:99ff:fe38:12b6 These packets are getting dropped by my firewall but I'm curious what's happening there. It's a very low packet rate at less than 20 Packets in an hour from about 10-12 different source addresses. And the packets I captured with tcpdump are looking like valid NTP requests. Sine the not-null part of the address is always 64 bits long I assume that this is maybe the result of some sort of a "prefix NAT" stunt which is spectacular failing on a non-filtered link. Does anyone else receive those packets? Or has an explaination what is going on there? My NTP server is currently the only service which is targeted by these weird packets. Greetings Max

Malware/ransomware current live distribution points

The various domains and IP address listed in the following file are, as we speak, acting as distribution/infection points for some sort of Javascript malware which is almost certainly a flavor of ransomeware.

Abuse-c documentation
by Tim Bruijnzeels 22 Jun '16

22 Jun '16

Dear working group, At RIPE 72 I promised to send links to abuse-c documentation. My apologies for the delay, we needed to update the documentation to make it clear that nowadays LIRs should set up their default maintainer in the LIR Portal and use webupdates, rather than use object editors. Please have a look at this documentation below and let us know if you have any concerns you would like to see addressed in documentation. https://www.ripe.net/support/abuse/how-to-find-abuse-contact-information#da… https://www.ripe.net/manage-ips-and-asns/resource-management/faqs-for-abuse… Kind regards, Tim Bruijnzeels Assistant Manager Software Engineering RIPE NCC

objection to RIPE policy proposal 2016-01 upheld for 5/2016 version
by Ruediger Volk 21 Jun '16

21 Jun '16

Dear colleagues, I want to formally confirm and underline my contributions to discussions @RIPE72: the slight softening of the newer version of proposal 2016-01 does not substantially resolve the concerns I raised in my objection to the earlier version. So I uphold my objection for the new version Subject: objection to RIPE policy proposal 2016-01 Date: Sun, 28 Feb 2016 19:38:10 +0100 Message-id: <11461.1456684690(a)x59.NIC.DTAG.DE> > I object to passing the policy as proposed. > There is no serious need for the policy, > and at this time and under current circumstance it would > actually be harmful. > I believe that the supposed good intentions would be better > served by other actions, and the policy focussing on enforcement > is ill advised. For the verbose detailled arguments and suggestions I refer to that old message. I note that other parties have raised additional concerns - those may fall under the "harmful" clause above, but I'm not going to argue in detail on those. Some of the discussion @RIPE72 did confirm what I wrote in the second paragraph of my objection message - as an attempt at constructive suggestions: > I understand that the current implementation of the RIPE database allows > legacy holders to enter abuse-c attributes for their legacy resources > ... > No PDP is needed to send friendly invitations to legacy holders to populate > their data objects with abuse-c information; > I'm sure asking the RIPE NCC to do this would not create an undue burden > or serious problem. Sadly I did not notice any followup on this yet. Thanks for your attention and consideration. Ruediger Volk

Sure. And a significant part of the resources being abused are in RIPE’s coverage area. I thought this new fangled internet thing was going to bring about a global connected world and make geography irrelevant?
