Garth Bruen Discussing Whois, DNSSEC and Domain Security

NameSmash has interviewed Garth Bruen, Internet security expert and creator of Knujon, on some key issues under discussion during the recent ICANN meetings in San Francisco. Topics include Whois, DNS Security Extensions (DNSSEC) and generic Top-Level Domains (gTLDs) -- issues of critical importance particularly with ICANN's expected roll-out of thousands of new gTLDs in the coming years. more

Passwords Are Not Enough: Without Two Factor Authentication Your Business Is At Risk

Passwords are no longer sufficient to maintain an adequate level of security for business critical infrastructure and services. Two-factor authentication should be considered the minimum acceptable level of access control. There have been two types of security stories in the technology news over the last few months that should be of particular concern to system administrators and those responsible for maintaining business network infrastructure. more

A Survey of DNS Security: Most Vulnerable and Valuable Assets

The following provides and introduction to a study by Venugopalan Ramasubramanian and Emin Gun Sirer, called "Perils of Transitive Trust in the Domain Name System". The paper presents results from a large scale survey of DNS, illustrating how complex and subtle dependencies between names and nameservers lead to a highly insecure naming system... "It is well-known that nameservers in the Domain Name System are vulnerable to a wide range of attacks. We recently performed a large scale survey to answer some basic questions about the legacy DNS." more

Bashbleed - A Nasty Reminder Never to Forget Security 101

After the botched burglary at the Watergate Apartments, every scam and scandal that hit the headlines became a 'gate' -- Irangate, Contragate, you name it. The Heartbleed bug is possibly the closest thing to Watergate that this generation of computer security had seen till the past few days -- an exploit in a component that is "just there" -- something you utterly rely on to be there and perform its duties, and give very little thought to how secure (or rather, insecure) it might be. So, fittingly, every such catastrophic bug in an ubiquitous component is now a 'bleed'. more

Search Engines and Registrars Getting Creative with Whois Database?

One of the best sources of information about sites on the web is the Whois database. A trio of patent applications from Go Daddy, published last week at the US Patent and Trademark Office, explores whether adding additional information to the Whois database might help reduce spam, phishing, and other fraudulent practices and improve search engine results. The patent filings from Go Daddy would add reputation information to the published Whois data to let others use it for a number of reasons, including enabling search engines incorporate it into their ranking mechanisms. ...The patent application from Google focuses upon fighting web spam using a wide range of data, including that associated with domain names. ...We can't really be certain that Google is presently using this information, but there are some indications that they may be... more

WannaCry: Patching Dilemma from the Other Side

WannaCry, originated firstly in state projects but spread by other actors, has touched upon myriads of infrastructure such as hospitals, telecommunication, railroads that many countries have labelled as critical. IT engineers are hastily presenting patching codes in various localized versions. The other patch needed, however, is more than technical. It is normative and legislative. The coding of that patch for a situation like this is in two layers of dilemma. more

NeuStar Experiences Partial Outage as DynDNS Tries to Turn up the Heat

NeuStar's UltraDNS faced attack on two fronts on Tuesday, March 31. One of the attacks was technical -- a massive denial-of-service attack. The second was a rather surprising opening strike from competitor Dynamic Network Services (DynDNS), which launched a full-scale (and in T1R's opinion, misguided) public relations broadside. First, to the actual denial of service attack. Contrary to many early reports, UltraDNS was not 'down' on Tuesday... more

M3AAWG Releases Anti-Abuse Best Common Practices for Hosting and Cloud Service Providers

Jointly published by the Internet Infrastructure Coalition (i2C) and the Messaging, Malware and Mobile Anti-Abuse Working Group, the new document outlines proven activities that can help Web hosting services improve their operations and better protect end-users. more

TLD Domain Abuse: Threat Report - First Half 2011

When it comes to building a robust globe-spanning network of crimeware and making the victims dance to a tune of the cyber-criminals' choosing, you're guaranteed to find domain name abuse at the heart of the operation. DNS provides the critical flexibility and underlying scalability of modern command-and-control (C&C) infrastructure. Cyber-criminals that master DNS (and manage to maintain the stream of new domain registrations that keep it fed) tend to find themselves in command of the largest and most profitable crimeware networks. more

On Comcast and Net Neutrality: Shouting Fire in a Theater

The Comcast traffic shaping case has stirred up passionate debate. Net neutrality proponents are calling for Comcast's head on a platter. The common argument is that Comcast's policy may stifle innovation and competition. If a service provider is allowed to exercise unregulated discretion in how it treats subscriber traffic, it is a slippery slope toward anti-competitive practices. Net neutrality says keep your hands off. Some are preaching net neutrality as if it were an inalienable human right like freedom of speech... more

Comcast’s Impressive System for Notifying Infected Users

Pretty much as long as there've been computers, one of the biggest challenges has been user education. How do you create software smart enough to inform a user when they're about to do something potentially disastrous - or, worse, when something disastrous has been done to them? As one of the world's largest access providers, Comcast has put a ton of thought into developing a notification system for their users. The solution Comcast developed involves, in effect, hijacking HTTP requests... 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

China Hacks Google, Etc.

Many news sources are reporting on how Google and other corporations were hacked by China. The reports, depending on vendor, blame either PDF files via email as the original perpetrator, or lay most of the blame on an Internet Explorer 0day. more

Brad Templeton in Response to Site Finder Controversy

A harmful, highly unilateral and capricious action. Tons of software out there depended on the ability to tell the difference between a domain name which exists and does not. They use that to give a meaningful, locally defined error to the user, or to identify if an E-mail address will work or not before sending the mail. Many used it as a way to tag spam (which came from domains that did not exist). It is the local software that best knows how to deal with the error. more

Two More Crypto Holes

If you work in computer security, your Twitter feed and/or Inbox has just exploded with stories about not just one but two new holes in cryptographic protcols. One affects WiFi; the other affects RSA key pair generation by certain chips. How serious are these? I'm not going to go through the technical details. For KRACK, Matthew Green did an excellent blog post; for the other, full details are not yet available. There are also good articles on each of them. What's more interesting are the implications. more
