The Problem With HTTPS SSL Runs Deeper Than MD5

The recent research highlighting the alarming practice of Secure Socket Layer (SSL) Certificate Authority (CA) vendors using the MD5 hashing algorithm (which was known to be broken since 2005) has shown a major crack in the foundation of the Web. While the latest research has shown that fake SSL certificates with MD5 hashes can be forged to perfection when the CA (such as VeriSign's RapidSSL) uses predictable certificate fields, the bigger problem is that the web has fundamentally botched secure authentication. more

Top 10 Spam Stories of 2008

Well, it's a yearly tradition in the western hemisphere that at the end of the year, we compose a top 10 list of the 10 most . Since it is now 2009, I thought that I would create my own list of the top 10 spam stories of 2008. Now, not all of these will be universally applicable to everyone, they are the top 10 stories as seen by me. more

More on ‘Researchers Hijack Storm Worm to Track Profits’

Always good for information on the spam economy, Brian Krebs of the Washington Post has just published a truly fascinating article: Researchers Hijack Storm Worm to Track Profits. Bottom line: a one-in-twelve-million conversion rate of spam to sales seems to be enough to keep the spam economy going. The article covers a project by researchers at UC San Diego and UC Berkeley, who managed to infiltrate the Storm Worm bot network and take over a small portion of it. more

Eugene Kaspersky: We Need Interpol for Internet, Law Enforcement Agencies Have Jurisdictional Limits

Eugene Kaspersky, co-founder of Internet security software Kaspersky Lab, was recently interviewed PC World where he talked about his views regarding cybersecurity and the evolution of malware. In response to fixing the problems with malware on the Internet, Kapersky says: "The Internet was never designed with security in mind. If I was God, and wanted to fix the Internet, I would start by ensuring that every user has a sort of Internet passport: basically, a means of verifying identity, just like in the real world, with driver's licenses and passports and so on. The second problem is one of jurisdiction. The Internet has no borders, and neither do the criminals who operate on the Internet. However, law enforcement agencies have jurisdictional limits, and are unable to conduct investigations across the globe. ... There is no such thing as anonymity on the Internet, for the average user." more

Phishers Expand Number of Top Level Domains Abused, Policy Changes Found Effective in Prevention

The new Global Phishing Survey released by the Anti-Phishing Working Group (APWG) this month reveals that phishing gangs are concentrating their efforts within specific top level domains (TLDs), but also that anti-phishing policies and mitigation programs by domain name registrars and registries can have a significant and positive effect. The number of TLDs abused by phishers for their attacks expanded 7 percent from 145 in H2/2007 to 155 in H1/2008. The proportion of Internet-protocol (IP) number-based phishing sites decreased 35 percent in that same period, declining from 18 percent in the second half of 2007 to 13 percent in the first half of 2008. more

Proposal for Signing the DNSSEC Root

The U.S. National Telecommunications and Information Administration (NTIA) is soliciting comments on signing the DNSSEC root. Ignore the caption on the page: this is not about DNSSEC deployment, which is already happening just fine. It's about who gets to sign the root zone. more

Why DNS is Broken, in Plain English

At ICANN's meeting in Egypt last week, I had the opportunity to try and explain to various non-technical audiences why the Domain Name System (DNS) is vulnerable to attack, and why that is important, without needing a computer science degree to understand it. Here is the summary. more

Phishing Registrar Accounts: eNom is First Target

Criminals are now looking to use established domain names, via phishing targeted at domain registrars. This is possibly related to ICANN finally moving to stop the black hat registrars of the world. According to the first report on the matter sent yesterday to Registrar Operations (reg-ops) mailing list, the attacks seem to be run by gang of child pornography spammers. more

Toxic Information

U.S. intelligence officials are increasingly worried that hackers could wreak havoc on the financial system. Read the story here in National Journal. Not that we need it, but here's yet another reason to worry about havoc in financial markets: U.S. intelligence officials increasingly fear that computer hackers could wreck banks and large financial institutions, or send stock markets into one more panicked frenzy, by covertly manipulating data and spreading false information. more

Are You Getting Your News From Spam? My Mother Does

This is a story about my mother and Obama. My mother: "Have you heard about Obama? Really impressive guy." Me: "What about him?" My mother: "x, y and z." Me: "Where did you hear about this?" My mother: "I read email too, you are not the only one who is into technology." Luckily, my mother bases her opinion on more than just spam messages... more

Estonian Cyber Security Strategy Document: Translated and Public

The Estonians have a public version of their cyber security strategy translated into English (currently available offline only). The concept of a national strategy for cyber security is one which I am particularly fond of... The following is the Summary section from the document which might be of interest... more

Internet Vigilantism

Atrivo (aka Intercage), a Concord, California-based Internet hosting service, disappeared from the Internet for around two days recently. They didn't go bankrupt or suffer a physical catastrophe. Their providers simply shut them down by refusing their traffic. This might very well be the first time in history that the Internet community, a cooperative association of networks with no governing body, has collectively put someone out of business, if only briefly. more

IGF Meeting Blacklisted

I got an e-mail from someone currently attending the Internet Governance Forum (IGF) meeting in Geneva. The e-mail ended up in my spam folder because the IP address used for the wireless LAN at the meeting is on a spambot/virusbot blacklist, namely cbl.abuseat.org. Apparently some guy there has his computer infected by a spambot or a virusbot... more

Study Assesses Potential Impact of DNSSEC on Broadband Consumers, Results Not Good

Recent collaborative test by Core Competence and Nominet have concluded that 75% of common residential and small SOHO routers and firewall devices used with broadband services do not operate with full DNSSEC compatibility "out of the box". The report presents and analyzes technical findings, their potential impact on DNSSEC use by broadband consumers, and implications for router/firewall manufacturers. Included in its recommendations, the report suggests that as vendors apply DNSSEC and other DNS security fixes to devices, consumers should be encouraged to upgrade to the latest firmware. more

Cyber Crime: An Economic Problem

During ISOI 4 (hosted by Yahoo! in Sunnyvale, California) whenever someone made mention of RBN (the notoriously malicious and illegal bulletproof hosting operation, the Russian Business Network) folks would immediately point out that an operation just as bad was just "next door" (40 miles down the road?), working undisturbed for years. They spoke of Atrivo (also known as Intercage). The American RBN, if you like... more
