Kido/Conficker network fear far too exagerated ...

While analysing Kido network behaviour Kaspersky Lab (my colleagues) has been able to develop an application that helped to get an in depth insight into the peer-to-peer network communications of the malware, which have been used to distribute updates over the last week. Over a 24 hour observation period KL identifeid 200652 unique IPs participating in the network, far less then initial estimated Kido infection counts. Of course we always have to be very careful naming numbers so also
this count could be not completely correct ... it shows however that it's definitely not 10 million as some sources reported before.
This is mostly due to the fact that only the latest variants of Kido are participating in the peer-to-peer network and only a fraction of the nodes infected with earlier variants have been updated with new variants.
You can find more at this link.

I'm getting sick from Twitter worms and Mikey Mooney...

What's up with Mikey Mooney?
He wrote a series of Twitter worms, got hired, got hacked and released yet another worm last night.
This one did extensive modifications to infected profiles; changing the name and bio to "Mikeyy" and the title of the profile to "Mikey and the Mysterious Treqz."
This variant downloaded additional scripts from .

The messages it sent were more philosophical in nature:
Be nice to your kids. They'll choose your nursing home. Womp. mikeyy.If you are born ugly blame your parents, if you died ugly blame your doctor. Womp. mikeyy.Every man should marry. After all, happiness is not the only thing in life. Womp. mikeyy.Age is a very high price to pay for maturity. Womp. mikeyy.Ninety-nine percent of all lawyers give the rest a bad name. Womp. mikeyy.If your father is a poor man, it is your fate, but if your father-in-law is a poor man, it's your stupidity. Womp. mikeyy.Money is not the only thing, it's everything. Womp. mikeyy.Success is a relative term. It brings so many relatives. Womp. mikeyy.'Your future depends on your dreams', So go to sleep. Womp. mikeyy.God made relatives; Thank God we can choose our friends.Womp. mikeyy.'Work fascinates me' I can look at it for hours ! Womp. mikeyy.I have enough money to last me the rest of my life. (unless I buy something) Womp. mikeyy.RT!! @spam Watch out for the Mikeyy worm ( link)FUCK. NEW MIKEYYY WORM! REMOVE IT: ( link)Mikeyy worm is back!!! Click here to remove it: ( link)

So to my opinion, please don't hire him but fire him!

Conficker/Kido starts with upgrade ...

The Conficker worm has started to update infected machines with a mystery package of data. It sprang into life late on 8 April. Analysis showed that the file had arrived via the peer-to-peer file transfer system that infected machines use to communicate.
In a bid to avoid alerting people to its activity, the update is slowly being trickled across the population of machines harbouring the older variant. The increased activity of Conficker/Kido and its analysis suggested a link with another well-known virus called Waledac. This malicious program steals sensitive data, turns PCs into spam relays and opens up a backdoor so the machine can be controlled remotely.
This latest Conficker/Kido variant - Net-Worm.Win32.Kido.js (Kaspersky Lab name)- is very different to the previous ones, with some notable points: once again it’s a worm, and it’s only functional until 3rd May. Kido doesn’t only download updates for itself; it’s the other files it downloads which really make the story interesting.
One of the files is a rogue antivirus application. The rogue software, SpywareProtect2009, can be found on,, spywareprotector-2009. You can find a picture on the weblog from Kaspersky Lab.
And this is possibly not the end yet...

Conficker/Kido FAQ (Frequently Asked Questions)...

Kido spreads via local networks and removable storage media. It penetrates computers by exploiting the MS08-067 vulnerability in Windows systems, which Microsoft released a patch for in autumn of last year. Experts believe that a significant number of machines had still not been patched by January, when the spread of Kido was at its peak. Failure to install the patch and to use effective antivirus protection has led to an epidemic: it’s currently estimated that between 5 and 6 million computers which have Internet connectivity are infected with Kido variants.
Several factors made today’s global Kido epidemic possible – neglecting to use antivirus products and the absence of an organization which is responsible for the security of the Internet and which unites and coordinates the efforts of governments and IT security experts.
Epidemics of a similar scale have happened in the past. However, the malicious programs which caused these epidemics did not have the extensive capability which Kido has to evade detection and prevent the disinfection of infected machines.
The third version of Kido is currently spreading on the Internet. This program implements the most sophisticated technologies used by malware authors – it downloads updates for itself from site addresses which are constantly changing; it uses local networks as an additional channel for updates; it uses strong encryption to protect itself; it has sophisticated mechanisms for disabling security services etc.
The third version of Kido updates itself by downloading code from 500 domains. These are chosen from a pool of 50,000 domains which is generated daily. The 500 domains are selected at random and this, together with the large number of domains makes it extremely difficult to monitor the domains used by the malicious program.
Because of this, Kido could become the most powerful cybercriminal tool which is highly resistant to being blocked in the history of the Internet. The gigantic botnet created by the authors of Kido gives cybercriminals the ability to conduct extremely powerful DDoS attacks on any Internet resource, to steal confidential data from infected machines and to spread unwanted content (i.e. huge spam mailings).
In March there were mass updates to older versions of this malicious program. On 1st April 2009 the Kido botnet will use the approach above to start receiving commands from its creators from 50,000 domains a day; what action the cybercriminals will take subsequently is difficult to predict.

Kaspersky Lab products successfully prevent all versions of Kido from penetrating users’ computers. Recommendations on how to delete the malicious program are available on the Kaspersky Lab technical support site.

We are monitoring constantly the situation.
All press and media will be updated as soon as we have more info.
But I'll personally think that we will not see too much activity today (April 1) but this can change of course any time and definitely any time after April 1...

BTW I'm using Twitter.
