ICANN Security Team Reports on Conficker Post-Discovery Analysis

A paper released today by ICANN provides a chronology of events related to the containment of the Conficker worm. The report, "Conficker Summary and Review," is authored by ICANN's Dave Piscitello, Senior Security Technologist on behalf of the organization's security team. more

How to Place Top-Level Domain Trust Anchors in the Root

The project to sign the DNS root zone with DNSSEC took an additional step toward completion yesterday with the last of the "root server" hosts switching to serving signed DNSSEC data. Now every DNS query to a root server can return DNSSEC-signed data, albeit the "deliberately unvalidatable" data prior to the final launch. Another key piece for a working signed root is the acceptance of trust anchors in the form of DS records from top-level domain operators. These trust anchors are used to form the chain of trust from the root zone to the TLD. more

DNSSEC Root Signature, Almost There!

IT security specialists have known for years that the plain DNS is not to be trusted. Any hope for improvement rests on the DNSSEC protocol deployment. In this post, I will review the current status in one critical aspect, namely the DNS root signature key management. The other two foremost are the application usage of DNSSEC protocol functionality and the operational front, or the extent of deployment in the DNS infrastructure. The operational front includes the support by the DNS root nameservers, but my focus on signature key management leaves this issue aside. more

Tackling Cyber Security: Should We Trust the Libertarians?

One of the RSS feeds that I read is Reason magazine, which is a web site for libertarians. In general, libertarians want less government intervention both in our personal lives and in the economy. The idea behind libertarians is that today's Republicans want less government intervention in our economy but are perfectly fine to have them dictate some aspects of morality. Similarly, today's Democrats want less government intervention in our personal lives but are perfectly fine with creating government bureaucracy to deliver social services. That's an oversimplified summary, but is more or less correct. About two months ago I got an article in my RSS feed where Reason was commenting on the government's response to the cyber war threats. more

EU’s Cyber Security Agency Identifying Five Areas as Critical IT Security

The EU's 'cyber security' Agency ENISA (The European Network and Information Security Agency) has launched a new report concluding that the EU should focus its future IT security research on five areas: cloud computing, real-time detection and diagnosis systems, future wireless networks, sensor networks, and supply chain integrity. more

First Internet War from a Social Psychological Perspective

The month-long series of coordinated attacks against Estonia's Internet in 2007 that shutdown websites of Estonia's government, those of its officials, banks and news agencies are believed to be based by various physiological principles including anonymity and contagion. more

Fake Anti-Virus Peddlers Taking Aggressive Steps to Avoid Detection

Over at Krebs on Secrity blog, Brian Krebs reports: "Purveyors of fake anti-virus or 'scareware' programs have aggressively stepped up their game to evade detection by legitimate anti-virus programs, according to new data from Google. In a report being released today, Google said that between January 2009 and the end of January 2010, its malware detection infrastructure found some 11,000 malicious or hacked Web pages that attempted to foist fake anti-virus on visitors." more

CallService.biz Shut Down by the FBI

Gary Warner over at Cyber Crime and Doing Time has a good post up this week about the CallService.biz website being shut down. I have posted a few good excerpts and added my comments to the end. ... Warner's take on the world of spam, malware, hacking and phishing is that unless people actually go to jail because they are spamming, the problem of spamming will never get better. That's because when the security industry fixes the latest hole or comes up with a new technology to stop the newest threat, spammers simply move onto another. more

Botnet Takedowns Having Limited Impact on Overall Spam Volumes, Says Google

Google, which through its Postini email security and archiving service processes over 3 billion email connections a day, reports that despite recent series of major botnet takedowns, spam levels during the first quarter of 2010 have held fairly steady. "This suggests that there's no shortage of botnets out there for spammers to use. If one botnet goes offline, spammers simply buy, rent, or deploy another, making it difficult for the anti-spam community to make significant inroads in the fight against spam with individual botnet takedowns." more

Geeks All Trust Each Other But Not in China

Brian Krebs has a post up the other day on his blog indicating that the amount of spam ending in .cn has declined dramatically due to steps taken by the Chinese government making it more difficult to get a domain ending in .cn... A cursory glance seems to confirm that the amount of spam from .cn as opposed to .ru has switched places. Indeed, if the CNNIC requires people to start writing in application forms, with a business license and identity card, that is seriously going to slow down the rate at which spammers can sign up and register new domains. more

FBI’s Chabinsky Defines and Describes Cybercriminal Operations at FOSE

A Sophisticated Online Counterfeit Ring

Online fakes can be a lucrative business and difficult to crack down on, due to the ease and low-cost of setting up multiple virtual storefronts and the ability to obfuscate an operation's identity. A federal lawsuit filed on March 1, 2010 by Polo Ralph Lauren and VF Corp. illustrates these points and highlights many of the intricacies of an online counterfeit ring. more

Another One (Partially) Bites the Dust

Following in the footsteps of Lethic, Waledac and Mariposa, yet another botnet has been taken offline. Not completely, though, it was only a partial disconnect. The Zeus botnet, also known as Zbot, is a trojan password stealer that captures passwords and sends them to the attacker. more

Authorities Take Down the Mariposa Botnet

There are a number of sources talking about the takedown of the Mariposa botnet... Spanish authorities, working with researchers from Panda Labs, Defence Intelligence and a couple of other educational institutions, took down the Mariposa botnet (Mariposa is the Spanish word for "butterfly"). The Mariposa botnet is an absolutely enormous with around 12 million (!) nodes doing its bidding. It was involved in things like credit card phishing and identity fraud. more
