In this webcast, Kaspersky Lab senior security researcher Roel Schouwenberg talks about the Diginotar certificate authority breach and the implications for trust on the Internet. Schouwenberg also provides a key suggestion for all major Web browser vendors.

S. Korean handlers are slow to take down the publicly distributed malicious code exploiting CVE-2012-0003, a vulnerability patched in Microsoft's January 2012 patch release MS12-004. We have discussed with reporters that the code has been available since the 21st, and a site appears to have been publicly attacking very low numbers of Korean users over the past day or so. The site remains up at this time.

    How much do you earn per day? If we look at how much a cybercriminal from Brazil earns every day, we’ll understand why Brazil is one of the main sources of malware in the world.

Brazilian cybercriminals really like to use short URLs to track infections and have their own stats. Here is the profile of one criminal using Bitly as a URL shortening service.

As some of you may remember, during 2011 we published a malware calendar wallpaper for each month of the year.

We're doing so again this year, with updated information from 2011. However, we've decided to take a slightly different approach this year and publish all 12 wallpapers in one place. You can find them all here.

We hope you like this year's designs and find the data interesting.

Kaspersky Lab malware researcher Tillmann Werner joins Ryan Naraine to talk about the threat from peer-to-peer botnets. The discussions range from botnet-takedown activities and the ongoing cat-and-mouse games to cope with the botnet menace.

    I was browsing through compromised websites used for spreading malware and found one from Argentina which belongs to a veterinary supplier. The admin panel got p0wned and, worst of all, it had a tab with the personal details of people who had posted their CVs (curriculum vitae). So, what exactly has happened? Well, basically lots of confidential information has been leaked and we are talking about home addresses, telephone numbers, details of education centers attended, mobile phone numbers, email addresses, marital status, children and even personal references. This is very bad because the same information can easily be used for all kinds of fraudulent activities: on-line ID theft, targeted attacks and so on. Here are just a few examples of real CVs uploaded and saved on the compromised site:

Following their major database breach, Zappos leadership is doing the right thing by what seems to be quickly and clearly communicating what data was accessed and what was not - there are no unexplained delays or confusion on their part about the event. It's like another Aurora moment in my book, when Google extraordinarily opened up about their breach while the other 30-odd Aurora-breached major corporations did the opposite, aggressively maintaining NDA's to hide their Aurora incidents and hide their heads in the sand. Zappos reset 24 million customers' passwords and emailed all of them about the problem last night.

Life looks good for Brazilian hackers: the absence of a specific law against cybercrime leaves them feeling so invulnerable that the bad guys are shameless about publicizing their thefts and showing off the profits of a life of crime. We showed some of this in a presentation at the latest Virus Bulletin Conference, and it’s commonplace to find YouTube clips of Brazilian bankers and carders reveling in their ill-gotten gains and rubbing their easy money in the faces of hard-up victims (there’s one example here, and several more out there). It’s also common to find bad guys’ profiles on social networks such as Twitter, Tumblr, etc. Everything is done out in the open, without fear of being caught.

To help new “entrepreneurs” or beginners interested in a life of cybercrime, some Brazilian bad guys started to offer paid courses. Others went even further, creating a Cybercrime school to sell the necessary skills to anyone who fancies a life of computer crime but lacks the technical know-how. On a website dedicated to selling these courses and promoting the “school”, a careful search turns up courses like “How to be a Banker”, “Kit Spammer” or “How to be a Defacer”.

Director of Kaspersky Lab's global research and analysis team Costin Raiu appears on Lab Matters to discuss the security ramifications of the growing dependence on cloud computing. The discussions center on the convenience of using consumer cloud services and some of the risks involved with outsourcing security to third-parties.

As we turn the page to 2012, it makes sense to sit back and take a look at what happened during the past twelve months in the IT Security world. If we were to summarize the year in one word, I think it would probably be “explosive.” The multitude of incidents, stories, facts, new trends and intriguing actors is so big that it makes it very hard to crack into top 10 of security stories of 2011.

What I was aiming for with this list is to remember the stories that also indicate major trends or the emergence of major actors on the security scene. By looking at these stories, we can get an idea of what will happen in 2012.
