Spamhaus reports Verizon routing hijacked IPs

Late last week Spamhaus published a blog post detailing their investigation into Verizon routing millions of IP addresses hijacked by spammers.
The Spamhaus blog post goes into some detail about what hijacked routing is.

For cybercriminals to make use of their stolen blocks however, a crucial step is to find an Internet Service Provider(ISP) or network with the ability to route these IP addresses to the rest of the Internet by using an autonomous system number(ASN). Also crucial is finding an ISP who won’t look too closely at the highly suspicious routing request. To get the routes to their stolen IP addresses announced, criminals will present forged authorization documents…

Actions like this are why an unknown IP is considered hostile until proven otherwise. I regularly tell clients than 99 times out of 100 when there’s mail from an IP never seen before it’s spam. I’ve often wondered if I’m understating the problem. That is way more than 99 IPs in 100 are sending spam. But I thought that would be an exaggeration and overly aggressive. Seeing the hijacked IPs just being routed through one US provider, though, tells me I am understating the problem.
Nevertheless, this is extremely bad behavior by Verizon and it’s disappointing that they seem unable or unwilling to take action about the spam and abuse coming from their network.

What do you think about these hot button issues?

bullhornIt’s been one of those weeks where blogging is a challenge. Not because I don’t have much to say, but because I don’t have much constructive to say. Rants can be entertaining, even to write. But they’re not very helpful in terms of what do we need to change and how do we move forward.
A few different things I read or saw brought out the rants this week. Some of these are issues I don’t have answers to, and some of them are issues where I just disagree with folks, but have nothing more useful to say than, “You’re wrong.” I don’t even always have an answer to why they’re wrong, they’re just wrong.
I thought today I’d bring up the issues that made me so ranty and list the two different points of views about them and see what readers think about them. (Those of you who follow me on Facebook probably know which ones my positions are, but I’m going to try and be neutral about my specific positions.)

Finally! Spam has a purpose

omrayspam_kabekAuthor Julie Czerneda posted about some of her writing techniques on Jim C. Hines’ blog today. Julie is one of my favorite authors. She’s a biologist so her science writing flows well for me. Too many folks try to write biology and get little nitpicky details wrong and it can disrupt the whole book for me. I spend way too much time thinking about the actual biology and lose track of the plot.
One part of her post stood out and made me smile, though.

Your system; your rules

In the late 90s I was reasonably active in the anti-spam community and in trying to protect mailboxes. There were a couple catchphrases that developed as a bit of shorthand for discussions. One of them was “my server, my rules.” The underlying idea was that someone owned the different systems on the internet, and as owners of those systems they had the right to make usage rules for them. These rules can be about what system users can do (AUPs and terms of service) or what about what other people can do (web surfers or email senders).
I think this is still a decent guiding principle in “my network, my rules”. I do believe that network owners can choose what traffic and behavior they will allow on their network. But these days it’s a little different than it was when my dialup was actually a PPP shell account and seeing a URL on a television ad was a major surprise.
But ISPs are not what they once were. They are publicly owned, global companies with billion dollar market caps. The internet isn’t just the playground of college students and researchers, just about anyone in the US can get online – even if they don’t own a computer there is public internet access in many areas. Some of us have access to the internet in our pockets.
They still own the systems. They still make the rules. But the rules have to balance different constituencies including users and stockholders. Budgets are bigger, but there’s still a limited amount of money to go around. Decisions have to be made. These decisions translate into what traffic the ISP allows on the network. Those decisions are implemented by the employees. Sometimes they screw up. Sometimes they overstep. Sometimes they do the wrong thing. Implementation is hard and one of the things I really push with my clients. Make sure processes do what you think they do.
A long way of dancing around the idea that individual people can make policy decisions we disagree with on their networks, and third parties have no say in them. But those policy decisions need to be made in accordance with internal policies and processes. People can’t just randomly block things without consequences if they violate policies or block things that shouldn’t be blocked.
Ironically, today one of the major telcos managed to accidentally splash their 8xx number database. 8xx numbers are out all over the country while they search for backups to restore the database. This is business critical for thousands of companies, and is probably costing companies money right and left. Accidents can result in bigger problems than malice.
