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.

It has been four months since Microsoft and Kaspersky Lab announced the disruption of Kelihos/Hlux botnet. The sinkholing method that was used has its advantages — it is possible to disable a botnet rather quickly without taking control over the infrastructure.However,as this particular case showed, it is not very effective if the botnet’s masters are still at large.

Not long after we disrupted Kehilos/Hlux, we came across new samples that seemed to be very similar to the initial version. After some investigation, we gathered all the differences between the two versions. This is a summary of our findings:

Let’s start with the lowest layer, the encryption and packing of Kelihos/Hlux messages in the communication protocol. For some reason, in the new version, the order of operations was changed. Here are the steps of processing an encrypted data for retrieving a job message which is organized as a tree structure:

№	Old Hlux	New Hlux
1	Blowfish with key1	Blowfish with new key1
2	3DES with key2	Decompression with Zlib
3	Blowfish with key3	3DES with new key2
4	Decompression with Zlib	Blowfish with new key3

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”.

Not so long time ago we found a very interesting piece of malware for Android. Unfortunately, it is not clear how it was spread but in any case it’s worth mentioning. The malicious application displays itself as ‘MADDEN NFL 12’ game after the installation.

The file size is over 5+ MB and actually is a Trojan that drops a set of malware components onto the system: root exploit, SMS Trojan and IRC bot. The .class file "AndroidBotAcitivity" maintains this dropper functionality. It creates a ‘/data/data/com.android.bot/files’ directory and sets ‘777’ permission (read/write/execute for all users). After that it extracts three files - ‘header01.png’ (root exploit), ‘footer01.png’ (IRC bot), ‘border01.png’ (SMS Trojan) - into this directory. Then it sets ‘777’ permission on the root exploit file and executes it. Finally, it displays the text ‘(0x14) Error - Not registred application’ on the screen.

If the exploit is executed successfully and the device is rooted, it launches the IRC bot ‘footer01.png’.

First of all, the IRC bot will try to delete ‘etc/sent’ using the ‘rm’ command:
