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
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
The highest court in Germany has ruled against telephone and email data retention used to track criminal networks. Melissa Eddy of the Global and Mail reports: "A law ordering data on calls made from mobile or landline telephones and e-mail exchanges be retained for six months for possible use by criminal authorities violated Germans' constitutional right to private correspondence, the Federal Constitutional Court ruled. In its ruling, the court said the law failed to sufficiently balance the need for personal privacy against that for providing security."

Leading US ISP, Comcast, has announced today its aggressive plans to deploy DNSSEC through out its netowrk. Chris Griffiths, Manager of DNS Engineering, writes: "We plan to implement DNSSEC for the websites we manage, such as comcast.com, comcast.net and xfinity.com, by the first quarter of 2011, if not sooner. By the end of 2011, we plan to implement DNSSEC validation for all of our customers." more
Last week Czech researchers released information on a new worm which exploits CPE devices (broadband routers) by means such as default passwords, constructing a large DDoS botnet. Today this story hit international news... The spread of insecure broadband modems (DSL and Cable) is extremely wide-spread, with numerous ISPs, large and small, whose entire (read significant portions of) broadband population is vulnerable. more
Stéphane Bruno writes: "In the first few hours that followed the earthquake, mobile service was completely disrupted. It was almost impossible to place a call, due to the combination of the damages on the cellular networks and the spike in phone calls. However, on some networks, SMS service was still available. People stuck under rubbles started texting to their friends and family (in Haiti and abroad) to tell them they were still alive and needed help. Those friends and family, not knowing what to do, started posting these SOS messages on their social networks, mainly on Facebook." more
I circulated this, and its precursors, notes about the necessity for diesel to keep the generators powering Boutilliers Hill NAP on the Hatian-Dominican Republic Border from failing, earlier this month on the North American Operators Group (NANOG) mailing list. Efforts by former ICANN people, in public service and in the private sector, were critical to bringing the continuity of the surviving infrastructure to the attention of the White House, the Department of State, and the Southern Command. more
Google is great at generating buzz, and they've done it again with their new social vitality tool, appropriately named Google Buzz. Buzz takes all of your Gmail contacts (and presumably other connections from elsewhere within the Googleplex), and makes them all your "friends" by default; it then shares your activity from Google Reader, YouTube, and other tools with all of them, and vice versa... more
Security is great when all the green lights are shining brightly and everything validates as intended, but what happens when you encounter failure? In this work we examine the behaviour of the DNS when security, in the form of DNSSEC is added, and we look at what happens when things do not happen as intended. What triggered this examination was a sudden increase in the traffic generated by secondary servers for the in-addr.arpa reverse zones in December 2009. more
The press, the blogosphere, CircleID - everybody has been discussing Craig Mundie's comment on the need for an "Internet Driver's License". Most of the reaction has been from privacy advocates fearing that this is simply another way to kill anonymity on the Internet. Oh well... that's the usual set of reactions. Now... the fun part is, a driver's license also shows that you have the competence to drive... more
A common security prediction for 2010 is the continued rise of malware and phishing attacks on mobile phones. The MarkMonitor Security Operations Center recently detected an interesting twist on this theme involving a popular smartphone and the latest smart technologies used by cybercriminals. In this case, instead of compromising a smartphone to steal its information, cybercriminals used phishing techniques to clone smartphones. more
The 2010 Domain Pulse, hosted by SWITCH (the .CH registry) was held in the snowy Swiss city of Luzern. Domain Name Security (DNS) was of particular importance in this year's meeting with DNSSEC being implemented in the root zone in 2010 by ICANN, and by many registries in the next few years. ICANN plan to have all root servers signed with DNSSEC by mid-2010 Kim Davies, Manager, Root Zone Services at ICANN told the meeting, starting with the L root server, then A root server with the last being the J root server as all are gradually signed. more
I have previously pointed out the shortcomings of good and user friendly support for DNSSEC in Microsoft's Server 2008 R2. During the period just after I wrote the post, I had a dialogue with Microsoft, but during the last months there has been no word at all. The reason I bring this up again is that more and more Top Level Domains (TLDs) now enable DNSSEC and also the fact that within six months the root will be signed. more
The Australian has a good article describing the efforts some of their ISPs are making in an attempt to clean up their act: the government is encouraging ISPs to detect computers on their network that are infected and part of botnets, and to communicate to the customer that their system is compromised... Unless the customer feels a little bit of pain they will not change their ways. more
There have been a number of reports recently about customer lists leaking out through Email Service Providers (ESPs). In one case, the ESP attributed the leak to an outside hack. In other cases, the ESPs and companies involved have kept the information very quiet and not told anyone that data was leaked. People do notice, though, when they use single use addresses or tagged addresses and know to whom each address was submitted. Data security is not something that can be glossed over and ignored. more
