“botnet herders can add it to its spam-spewing botnet” —Fahmida Y. Rashid in eWeek.com

This reporter spits out a string of alliterative language that labels the problem that SpamRankings.net helps diagnose.

Fahmida Y. Rashid wrote in eWeek.com 8 June 2011, UT Researchers Launch SpamRankings to Flag Hospitals Hijacked by Spammers:

“Poor security measures are generally responsible for employee workstations getting compromised, either by spam or malicious Web content. Once the machine is compromised, the botnet herders can add it to its spam-spewing botnet to send out malware to even more people. The original employee or the organization rarely has any idea the machine has been hijacked for this purpose.”
That’s a pretty good explanation for why outbound spam is a proxy for poor infosec.

Krebs on SpamRankings.net

Brian Krebs wrote on his blog, Naming & Shaming Sources of Spam:
A new resource for spotlighting organizations that are unwittingly contributing to the global spam problem aims to shame junk email havens into taking more aggressive security measures.

SpamRankings.net is a project launched by the Center for Research in Electronic Commerce at the University of Texas at Austin. Its goal is to identify and call attention to organizations with networks that have been infiltrated by spammers.

Andrew Whinston, the center’s director, said the group initially is focusing on health care providers that appear to be infected with spam bots. “Nobody wants to do business with a bank or hospital or Internet hosting company that has been hijacked by spammers,” Whinston said. “It’s an environment in which user data can be stolen or compromised.”

The rest of his writeup quotes me quite a bit, and everyone knows I’m quite shy, so please go read his blog!

I will add that May data is live now on SpamRankings.net. Also, organizations that do better over time may want to brag, as has happened with a couple of U.S. organizations in May.

Here’s Krebs’ final paragraph:

I applaud this effort, and hope that it gains traction. I remain convinced that the Internet community would benefit from a more comprehensive and centralized approach to measuring badness on the Web. There are many existing efforts to measure reputation and to quantify badness online, but most of those projects seek to enumerate very specific threats (such spam or hacked Web sites) and measure the problem from a limited vantage point. What is lacking is an organization that attempts to collate data collected by these disparate efforts and to publish that information in near real-time.

Egypt Returns

Egypt returned to the Internet about 09:30 GMT today (2 February 2011). This sudden return after being as suddenly disconnected one week ago (27 January 2011) is obviously not due to ordinary causes such as congestion, cable cut, or router failure. This political disconnection of an entire country does not seem to have helped the regime responsible for it; quite the opposite.

Our Friend Unfairly Maligned in London’s Court

Many of you are concerned as am I about our friend who has been hauled into court in London and unfairly maligned for the “crime” of distributing some government communications that he got from an anonymous source. I know our friend also has been a bit playful out of wedlock, and even had a son that way, but I don’t see what that has to do with the matter at hand.

Our friend represented his agency in the matter of procuring and forwarding the communications “as a public act, dealing with the public correspondence of public men.” His accusers were having none of it:

Into what companies will the fabricator of this iniquity hereafter go with an unembarrassed face, or with any semblance of the honest intrepidity of virtue? Men will watch him with a jealous eye &em; they will hide their papers from him, and lock up their escritoires. Having hitherto aspired after fame by his writings, he will henceforth esteem it a libel to be called a man of letters…
His accusers made him out to be a vindictive destroyer of public confidence. He had “forfeited all the respect of societies and of men” and was not a gentleman, rather a common thief.

I am happy to hear our friend has been released by the court in London, although two days later he was fired from his job as deputy postmaster general of North America. Continue reading →

Transparency in Rome

Here’s my presentation, Transparency as Incentive for Internet Security: Organizational Layers for Reputation, from RIPE 61 in Rome. This presentation summarizes the two previous RIPE Labs papers about proposed new organizational layers and outbound spam ranking experiments.

RIPE-NCC is the oldest of the Regional Internet Registries (RIRs), and RIPE is the deliberately unorganized association of interested parties that meets twice a year and holds discussions online in between. It’s a mix of operations, research, and socializing. Topics range from obscure details of deploying IPv6 to organizational proposals such as what I was talking about. 430 people attended the meeting in Rome, which was quite a few more than the dozen or two of the first RIPE meeting I went to many years ago.

Interesting questions were asked. I may blog some of them.

Daniel Karrenberg and RIPE Atlas

Daniel Karrenberg shows an animation related to RIPE Atlas, RIPE’s new active measurement project using USB-powered dongles scattered around the Internet.

Video by jsq at RIPE 61 in Rome, Italy, 15 Nov 2010. His slides, the RIPE Atlas home page, and the conference will put up video of all the talks within about a day.

PS: My talk is 11AM Rome time tomorrow, Tuesday 16 Nov.

Outbound Spam Ranking Experiments

Should Uganda Telecom be counted as a Belgian ISP for outbound spam rankings?

Which matters most: history, topology, business headquarters location, or some other criterion?

These are some questions that come up in designing experiments in rolling out a reputation system for outbound spam. More on this in the RIPE Labs article (8 Nov 2010), Internet Reputation Experiments for Better Security.

Such experiments can draw on fifty years of social science research and literature, first crystalized as Social Comparison Theory by Leon Festinger in 1954, that indicate that making personal reputation transparent changes personal behavior. More recent research indicates that the same applies to organizations. Using anti-spam blocklist data, it is possible to make E-Mail Service Provider (ESP) behavior (banks, stores, universities, etc., not just ISPs) in preventing or stopping outbound spam transparent, and this paper is about experiments to see how the resulting reputation actually changes ESP behavior.

Organizing the Cloud Against Spam

In RIPE Labs, here’s a paper on Internet Cloud Layers for Economic Incentives for Internet Security by the IIAR Project (I’m the lead author). Anti-spam blocklists and law enforcement are some Internet organizational layers attempting to deal with the plague of spam, so far reaching a standoff where most users don’t see most spam, yet service providers spend large amounts of computing and people resources blocking it.
The root of the ecrime problem is not technology: it is money.
