How to Stop Spam

I got a letter the other day from AOL postmaster Carl Hutzler, about how the Internet community could get rid of spam, if it really wanted to. With his permission, here are some excerpts. "Spam is a completely solvable problem. And it does not take finding every Richter, Jaynes, Bridger, etc to do it (although it certainly is part of the solution). In fact it does not take email identity technologies either (although these are certainly needed and part of the solution)." more

Bad Journalism, IPv6, and the BBC

Here's a good way to frighten yourself: Learn about something, and then read what the press writes about it. It's astonishing how often flatly untrue things get reported as facts. I first observed this back in 1997 when I was a Democratic lawyer in the U.S. House of Representatives working on the (rather ridiculous) campaign finance investigation. (The investigating committee's conspiracy-minded chairman was famous for shotgunning pumpkins in his backyard in order to figure out exactly how Hillary snuffed Vince Foster)...More recently, I've seen the same discouraging phenomenon in reporting on technology and, in particular, the Internet. more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

Road Warrior at Risk: The Dangers of Ad-Hoc Wireless Networking

Most people who have wireless Ethernet at home, or the office, connect to the wireless network by attaching to a wireless Access Point, or AP. This method of wireless networking is called "Infrastructure Mode". If you have a secure wireless network configured in "Infrastructure Mode" you are using MAC address filtering, some level of encryption, and have made some additional changes to your AP in order to prevent just anyone from using it or capturing data. ...However, for those who are not using "Infrastructure Mode", and are configured to communicate from machine to machine, or "Ad-Hoc", there are a few things you should be aware of. more

Twenty Myths and Truths About IPv6 and the US IPv6 Transition

After hearing over 350 presentations on IPv6 from IPv6-related events in the US (seven of them), China, Spain, Japan, and Australia, and having had over 3,000 discussions about IPv6 with over a thousand well-informed people in the IPv6 community, I have come to the conclusion that all parties, particularly the press, have done a terrible job of informing people about the bigger picture of IPv6, over the last decade, and that we need to achieve a new consensus that doesn't include so much common wisdom that is simply mythical. There are many others in a position to do this exercise better than I can, and I invite them to make a better list than mine, which follows. more

Could IP Addressing Benefit from the Introduction of Competitive Suppliers?

An article written by Paul Wilson, Director General of Asia Pacific Network Information Centre (APNIC), and Geoff Huston, Senior Internet Research Scientist at APNIC. "In recent months proposals have been made for the introduction of competition into the system of allocation of IP addresses. In particular, calls have been made for new IP address registries to be established which would compete with the existing Regional Internet address Registries (RIRs). Specific proposals have been made by Houlin Zhao of the ITU-T and by Milton Mueller of the Internet Governance Project, both of which propose that the ITU itself could establish such a registry group, operating as a collection of national registries." ...It would appear that part of the rationale for these proposals lies in the expectation that the introduction of competition would naturally lead to outcomes of "better" or "more efficient" services the address distribution function. This article is a commentary on this expectation, looking at the relationship between a competitive supply framework and the role of address distribution, and offering some perspective on the potential outcomes that may be associated with such a scenario for IP addresses, or indeed for network addresses in general. more

Study Finds Spammers Use P2P Harvesting to Spam Millions

A recent study conducted by Blue Security reports how Internet users can unknowingly expose their contacts' emails addresses to Spammers while sharing files, music, games and DVDs over Peer-to-Peer (P2P) networks. The study has uncovered hundreds of incidents where files containing email addresses were made accessible in P2P networks. more

Protecting the Internet: Certified Attachments and Reverse Firewalls?

In many respects the internet is going to hell in a hand basket. Spam, phishing, DNS poisoning, DDoS attacks, viruses, worms, and the like make the net a sick place. It is bad enough that bad folks are doing this. But it is worse that just about every user computer on the net offers a nice fertile place for such ill behavior to be secretly planted and operated as a zombie under the control of a distant and unknown zombie farmer. ...Some of us are coming to the converse point of view that the net is being endangered by the masses of ill-protected machines operated by users. more

Internet to ITU: Stay Away from My Network

An ITU document entitled "Beyond Internet Governance" crossed my desk earlier this week. Given that I had absolutely nothing better to do, I decided to give it a read. The audacity of the ITU Secretariat is nothing less than shocking. It has been a long while since I read such a self-serving, narrow-minded and inaccurate document. The backbone of the ITU's contention rests on the premise that something called the Next Generation Network and the contention that this network will act as one big bug fix for all the problems created by current inter-networking technology. more

Survey Predicts Attacks on the Network Infrastructure Within 10 Years

Pew Internet Project has released a report called "The Future of the Internet" based on a recently conducted survey where 1,286 internet experts are said to have looked at the future impact of the internet and assessed predictions about how technology and society will unfold. The following is and excerpt from the report predicting at least one devastating attack will occur in the next 10 years on the networked information infrastructure or the United States power grid. more

A Network by Any Other Name

Last month Wired News, the online service that grew out of Wired Magazine, decided that it was going stop using an upper-case 'I' when it talked about the internet. At the same time Web became web and Net became net. According to Tony Long, the man responsible for their style guide, the change was made because 'there is no earthly reason to capitalize any of these words'. In fact, he claims, 'there never was.' ...Forgive me for saying, but those who choose 'internet' over 'Internet' are as wrong as those who would visit london, meet the queen or go for a boat trip down the river thames. more

Sender ID: A Tale of Open Standards and Corporate Greed? - Part I

A long long time ago when the Internet was still young and most people were still using clunky Apples, PCs and mainframes; two documents were published by the Advanced Research Projects Agency (ARPA), part of the US Government's Department of Defense. They were called "RFC 821 - Simple Mail Transfer Protocol" and "RFC 822 - Standard for the format of ARPA Internet text messages" respectively. Written by the John Postel and Dave Crocker respectively, often referred to as some of the founding fathers of the Internet, they defined a simple text-based email system for the use of the fledging network then called the "ARPA Internet"... more

10 Reasons Why Involving Government in Spam Control is a Bad Idea

1. Many jurisdictions already have laws which cover abuse of computer systems and networks -- and spam is of course abuse. These laws are only sporadically enforced, however, usually when a sufficiently visible/powerful entity is the aggrieved party. Adding more laws (a) is redundant and (b) does not increase enforcement. 2. Laws are only enforced as law enforcement has resources available. Spam/abuse is not a high priority unless a sufficiently visible/powerful entity makes it so, and those cases are rare. more

80% of Spam Originating from Home PCs

The majority of spam -- as much as 80 per cent of all unsolicited marketing messages sent -- now emanates from residential ISP networks and home user PCs. This is due to the proliferation of spam trojans, bits of surreptitious malware code embedded in residential subscriber PCs by worms and spyware programs. Worm attacks are growing in frequency because they provide a fast means of infecting a vast number of computers with spam trojans in a very short period of time. It's no surprise that many service providers report an upsurge in spam traffic immediately following a worm attack. more

U.S. Moving Forward with ENUM

One of the pieces of infrastructure that makes all kinds of networks work and yet gets very little attention is the directory. Directories are big business. For example, there's directory of telephone numbers run by NeuStar, Inc. NeuStar has annual revenues of $92 million. Now, according to Light Reading, AT&T Corp. and MCI Inc., together with unidentified cable companies, telephone companies, and ISPs are preparing to form a Limited Liability Corporation (LLC) that will run a process to define a new company that will run ENUM. more
