VoIP/IP Telephony in Estonia: Disrupted by Botnets?

With my post earlier this month about the possibility of SIP botnets [also featured here on CircleID], I've had a number of people asking about more information and wondering about the possible impacts. And while I will write more on botnets in general, as far as the potential impact of "botnets" in general, one need only look over at the current situation in Estonia... Now, perhaps Russia is behind the attack... perhaps not. There are obviously much larger political issues going on between the two states. more

Hotmail Running Its Own SMTP Variation

Companies sensible to effective delivery of email to all free email services may have noticed problems with deliveries to Hotmail addresses. Despite the SMTP dialog ending with a successful "250" return code, recipients don't see the message. In their Guidelines, MSN require thorough compliance with IETF standards. However, it seems they have their own interpretation about provisions for Delivery Status Notifications, a.k.a. bounces, that servers must send after they have accepted responsibility for delivering the message... more

Net Neutrality Reflection

So this afternoon my charge is to lay out all the Net Neutrality (NN) issues to a bar association that doesn't have a telecom subcommittee... Cringely says that "In the end the ISPs [network providers] are going to win this [network neutrality] battle, you know. The only thing that will keep them from doing that is competition, something it is difficult to see coming along anytime soon..." more

Book Review: Sex.com by Kieren McCarthy

On the face of it, Kieren McCarthy's Sex.com was a book that could have written itself: a notorious, well-publicised feud over the most valuable domain name in existence, between two charismatic men -- one a serial entrepreneur with a weakness for hard drugs (Gary Kremen), the other a gifted con-man with delusions of grandeur (Stephen Cohen). It's a story replete with vicious acrimony, multi-million dollar lawsuits, and rumours of gunfights between bounty hunters in the streets of Tijuana. Thankfully, McCarthy wasn't content to just bundle together all the articles he's written about Sex.com over the years and slap a cover on the front... more

Clues about the Future of TV

A recent article chronicles the telcos' slow start in cable TV. I don't think the telcos stand a chance of succeeding in cable TV. Instead, if they're to succeed at all, they'll probably buy or form alliances with existing cablecos... But they'd better start swimming, because the times are a changing.. more

More on Broadband Router Insecurity and Being Proactive

Fergie replied on NANOG to my recent post on the subject of broadband routers insecurity: "I'll even go a step further, and say that if ISPs keep punting on the whole botnet issue, and continue to think of themselves as 'common carriers' in some sense -- and continue to disengage on the issue -- then you may eventually forced to address those issues at some point in the not-so-distant future..." He is right, but I have a comment I felt it was important - to me - to make. Not just on this particular vulnerability, but on the "war"... more

Ailing ETO-2002 and the Demise of PKI

The only Cyber law passed in Pakistan till date is the famous ETO-2002 (Electronic Transaction Ordinance - 2002). It required Ministry of IT&T to set up a Central Repository for all digital certificates and in addition to set up a body to be named as Electronic Certification Accreditation Council (ECAC) to accredit Electronic Certification Authorities to be established in the country... In this regard, government has not only closed its eyes and has blindly trusted the only certificate authority (CA) in the country operated by a private business group, it has also mandated the citizens and business to trust it. Case in point is Central Board of Revenue (CBR) that has told all taxpayers to digitally sign the emails using the certificates issued by this private party... more

Broadband Routers and Botnets: Being Proactive

In this post I'd like to discuss the threat widely circulated insecure broadband routers pose today. We have touched on it before. Today, yet another public report of a vulnerable DSL modem type was posted to bugtraq, this time about a potential WIRELESS flaw with broadband routers being insecure at Deutsche Telekom. I haven't verified this one myself but it refers to "Deutsche Telekom Speedport w700v broadband router"... more

Stop! Don’t Forward That E-mail!

Forwarding e-mail is so easy that it must be legal, right? Not everyone thinks so. Ned Snow at the University of Arkansas recently wrote A Copyright Conundrum: Protecting Email Privacy that argues that forwarding violates the sender's copyright rights, so it's not. The article is quite clever and is (as best I can tell, not being a legal historian) well researched, even if you agree with me that its conclusions are a bunch of codswallop... more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

A story... ZZZ Telemarketing (not a real name) is locked in a heated fight with their bitter rival, YYY Telemarketing (also not a real name), to win a very large lead generation contract with Customer X. Customer X has decided to run a test pitting the two companies against each other for a week to see who can generate the most leads. The ZZZ CEO has said to his staff that it is "do or die" for the company. If they fail to win the contract, they will have to shut down -- they need to do "whatever it takes" to win over YYY. A ZZZ staffer discovers that part of why YYY has consistently underbid them is because they are using SIP trunks to reduce their PSTN connection costs. But the staffer also discovers that YYY is using very cheap voice service providers who run over the public Internet with no security... more

Criminal Checks Needed for Domain Name Tasting, Kiting, Spying

International organisations should step in to prevent the "tasting," "kiting" and "spying" related to Internet domain names, say representatives from the US telecommunications and trademark industries. These new activities are dramatically altering online commerce and impacting legitimate businesses, and the United States Federal Trade Commission (FTC), World Intellectual Property Organization (WIPO) and the Internet Corporation for Assigned Names and Numbers (ICANN) should take action, they say. The US Anti-Cybersquatting Consumer Protection Act (ACPA) had too many loopholes given the actual trends in the domain name secondary market, said Sarah Deutsch, vice president and associate general counsel for Verizon, and Marilyn Cade, former AT&T lobbyist and now consultant on Internet and technology issues... more

Ed Richards of Ofcom on Net Neutrality

Ed Richards, Chief Executive of Ofcom, was at Columbia today... NN (Net Neutrality) debate does give us insight into importance of disclosure to consumers -- consumers should be able to switch providers, and they should know which ISPs are making prioritization decisions. This should be an obligation of suppliers to communicate this information to consumers. In particular, he says that Ofcom is actively exploring whether network operators whose traffic shaping activities change materially should have to tell consumers -- and if these changes are significant consumers should be allowed to break their contracts with the provider without penalty... more

Geographic Implications of DNS Infrastructure Distribution

The past several years have seen significant efforts to keep local Internet communications local in places far from the well-connected core of the Internet. Although considerable work remains to be done, Internet traffic now stays local in many places where it once would have traveled to other continents, lowering costs while improving performance and reliability. Data sent directly between users in those areas no longer leaves the region. Applications and services have become more localized as well, not only lowering costs but keeping those services available at times when the region's connectivity to the outside world has been disrupted... The recently published paper, "Geographic Implications of DNS Infrastructure Distribution" focuses on the distribution of DNS infrastructure. more

ICANN’s WDPRS Report and Plan to Clean Up Whois Records

ICANN's recently released report, ICANN's Whois Data Accuracy and Availability Program: Description of Prior Efforts and New Compliance Initiatives [PDF], is a summary of the Whois Data Problem Report System's (WDPRS) reports spanning a one-year period that concluded at the end of Fenruary 2007. In case you're not familiar with the WDPRS, it's system that tracks complaints about inaccurate or incomplete whois entries. Notable facts from the report include: There were 50,189 reports for which ICANN received follow-up responses during the year... more

.xom, BrandJacking and Error-Search

BusinessWeek is running a column called 'Brandjacking' on the Web. In summary, nobody likes deliberate cybersquatting or typosquatting. But if Typo domain-names did not exist, the traffic would continue to flow to Microsoft or Google via the browser's error search where those very large companies would make money in the same manner as the 'evil cybersquatters'... more
