3FN + FTC = Some Less Spam From Some ASNs

A research project I'm assisting at the University of Texas at Austin notes that:

On Tuesday 2 June 2009, the U.S. Federal Trade Commission (FTC) took legal steps that shut down the web hosting provider Triple Fiber network (3FN.net).

Looking at Autonomous Systems (ASNs) listed in the spam blocklist CBL,

Rip van Security

Gunnar Peterson asks a question:

...how do you primarily rely on network security as we have done for the Web's life, when the Cloud abstracts the network away?

Gunnar points out IT security has been using firewalls and SSL as primary security for every network acccess software change since 1995.

In 1999 when SOAP emerged as a firewall-friendly protocol designed for the explicit reason to go through the firewall, that should have been a wake up call to Information Security that the "firewall + SSL" security architecture was past its prime, but here 10 years later we are still hitting the snooze button.

Here many years after we lost email for everybody but aging geeks and banks, IT security continues to snooze like Rip van Winkle. While the world changes around it:

VZ Port 587: Good Try

Back in February, Verizon announced it would start requiring outbound mail go through port 587 instead of port 25 during the next few months. It seemed like a good idea to squelch spam. Most other major ISPs did it. People applauded Verizon for doing it.

Unfortunately, it seems that if it had any effect it was short-lived. Looking at anti-spam blocklists on a daily basis, a couple of Verizon Autonomous Systems (ASes), AS-19262 and AS-701, do show dips in blocklist listings on the blocklist PSBL in March. But they don't last.

Spammers are very adaptable, partly because the botnets they use are adaptable. Good try, Verizon.

This information is from an NSF-funded academic research project at the University of Texas at Austin business school. Thanks to PSBL for the blocklist data.

Van Meter on Barabasi and Doyle on Internet topology and risks

Rodney Van Meter, co-teaching a class by Jun Murai, posts notes on why Albert-László Barabási (ALB) is both right and wrong about the Internet (it is more or less a scale-free network when considered as a network of Autonomous Systems (AS), but contrary to ALB's assumption John Doyle and others have pointed out that the bigger nodes are not central, an AS as a node would be somewhat difficult to take out all at once, there are both higher and lower layer topologies that make the Internet more robust, and the Internet's biggest problem isn't topology at all:

The most serious risks to the Internet are not to individual "nodes" (ASes), but rather stem from the near-monocropping of Internet infrastructure and end nodes, and the vulnerability of the system to human error (and political/economic considerations):

Monoculture, who would have thought it?

For that matter, the Internet's ability to reroute has been very useful to ameliorate topological link breaks at the physical layer, for example undersea cables in the Mediterranean Sea twice last year.

MySpace Anti-Phishing

Shing Yin Khor of Fox Interactive Media, which owns MySpace, gave an entertaining talk at APWG in which she gave a good case that MySpace has mostly eliminated phishing ads on MySpace and is busily suppressing other phishing.

Throwing money at the issue of phishing actually works.

MySpace's anti-phishing forces include former law enforcement people, including a former federal and state prosecutor, a former L.A. D.A., and a former FBI agent. They have successfully sued spam king Scott "ringtones" Richter and his CPA empire.

MySpace does have an advantage in actually hosting all displays and messages. It's good to be a many-hundred-million shopping mall. She didn't say that; I did. She did say they use MySpace specific measures such as education via Tom's profile. Tom was one of the founders of MySpace. Every new user gets Tom as a friend, so his online persona (pictured) has 240 million friends, so that's a channel that reaches most of their users. She did say:

Education is just as important as technical measures.

What works on MySpace will work on other social network sites.

But Shing's theme of pro-active measures against phishing and spam is one other organizations could take to heart. Don't think you can do nothing: you can.

Of course, if you have fewer than 200 million users, you may want to band together with other organizations, for example by joining APWG. Even MySpace does.

APWG Atlanta Buckhead

Five years of the Anti-Phishing Working Group! Dave Jevans gave a retrospective, followed by country reports:

Japan: Pretending to be grandchild to get bank account transfer is popular. ATM scams are the most lucrative.

Russia: Second biggest global source of spam. Ecrime economy is ten times the si ze of the anti-ecrime industry, and that's a problem.

Brazil: Most phishing is done locally. Is all organized crime.

I don't want to go into too much detail, even though the bad guys don't seem to need any help. APWG continues to climb the ecrimeware curve, catching up with th e miscreants.

Further Hardin Debunking

Regarding Perry's comment to the previous post, the point is that the specific example on which Hardin based his thesis, the one everyone cites in support of it, is not borne out by the evidence, not that he presented any evidence for it in the first place.

Further, that it's not a tragedy in the sense Hardin meant: that of a Greek tragedy in which a flaw of character inevitably leads to the demise of the protagonist. Individuals are not inevitably disposed to claw out their own at the expense of everyone else. Sometimes people realize that there really is such a thing as the common good; that benefiting everyone benefits themselves.

Yes, I know about the Sahara and the Sahel; I've been there; I've seen the goats gnawing away at everything.

The solution is not state central planning: you cite Chinese lakes; I'll cite the Aral Sea.

The solution is also not privatization of the commons: look at the wildfires in the U.S. west exacerbated by subdivisions built in forests.

Solutions that work seem to involve combinations of innovation, education, and especially cooperation. Like this one:

In the late 1970s, when the problems of desertification, combined with population growth, drought and grinding poverty in West Africa first began to get sustained global attention, the prognosis was mostly gloom and doom. And as has been well documented, foreign aid has been less than successful in improving matters. In Yahenga, Reij and Fabore note, efforts to modernize agriculture through large-scale mechanized operations usually failed, for a variety of reasons. The spread of zai hole planting spearheaded by Sawadogo was mostly carried out by the local farmers themselves, with limited support from the government or foreign donors. Those with access to labor dug the holes, and used local sources of organic manure to fill them.

A tree grows in the Sahel, Andrew Leonard, How the World Works, Wednesday, Oct. 4, 2006 11:22 PDT

The "free market" isn't enough. Cooperation on scales from local to global is also needed. And it does happen, despite Garrett Hardin's myth that it can't.

Debunking the Tragedy of the Commons

Interesting article here making a point that should have been obvious for forty years. When Garrett Hardin published his famous article about the "tragedy of the commons" in Science in December 1968, he cited no evidence whatsoever for his assertion that a commons would always be overgrazed; that community-owned resources would always be mismanaged. Quite a bit of evidence was already available, but he ignored it, because it said quite the opposite: villagers would band together to manage their commons, including setting limits (stints) on how many animals any villager could graze, and they would enforce those limits.

Finding evidence for Hardin's thesis is much harder:

The only significant cases of overstocking found by the leading modern expert on the English commons involved wealthy landowners who deliberately put too many animals onto the pasture in order to weaken their much poorer neighbours’ position in disputes over the enclosure (privatisation) of common lands (Neeson 1993: 156).

Hardin assumed that peasant farmers are unable to change their behaviour in the face of certain disaster. But in the real world, small farmers, fishers and others have created their own institutions and rules for preserving resources and ensuring that the commons community survived through good years and bad.

Debunking the `Tragedy of the Commons', By Ian Angus, Links, International Journal of Socialist Renewal, August 24, 2008

So privatization is not, as so many disciples of Hardin have argued, the cure for the non-existant tragedy of the commons. Rather, privatization can be the enemy of the common management of common resources.

What does this have to do with risk management? Well, insurance is the creation of a managed commons by pooling resources. Catastrophe bonds are another form of pooled resources, that is, a form of a commons.

On the Internet, the big problem with fighting risks like phishing, pharming, spam, and DDoS attacks is that the victims will fail if they go it alone. The Internet is a commons, and pretending that it isn't is the problem. Most people and companies don't abuse the Internet. But a few, such as spam herders and some extremist copyright holders (MPAA, RIAA), do. They need to be given stints by the village.

Paypal Says Old IE is Like Car Without Seat Belt: EV SSL blocking

The eBay-owned company, which runs a Web-based payment system that allows the transfer of funds between bank accounts and credit cards, said browsers that do not have support for blocking identity theft-related Web sites or for EV SSL (Extended Validation Secure Sockets Layer) certificates are considered "unsafe" for financial transactions.

"In our view, letting users view the PayPal site on one of these browsers is equal to a car manufacturer allowing drivers to buy one of their vehicles without seat belts," said PayPal Chief Information Security Officer Michael Barrett.

...

Barrett only mentioned old, out-of-support versions of Microsoft's Internet Explorer among this group of "unsafe browsers," but it's clear his warning extends to Apple's Safari browser, which offers no anti-phishing protection and does not support the use of EV SSL certificates.

Now on the one hand, I think EV SSL is color-coded checklist security candy:

Auditing Georgia Government Security

Georgia's governor wants to standardize information security reporting across the entire state government:

The Executive Order calls for a single set of information security reporting standards for all agencies to follow. Currently, state agencies use a variety of reporting standards, making it difficult to measure information security across state government or to track progress from year to year.

Governor Perdue has directed the Georgia Technology Authority (GTA) to work with the Georgia Department of Audits and Accounts and the Governor's Office of Planning and Budget to develop a reporting format and required content for agency information security reports. Each agency will be responsible for reporting to GTA at the end of the fiscal year. GTA will compile agency reports into a single Enterprise Information Security Report, available by October 31 of each year.

— Gov. Perdue Signs Executive Order Strengthening Georgia's Information Technology Security, News Report, Government Technology, Mar 20, 2008

I think this is a good move. Now how about monthly reporting in a publicly visible web page.
