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...
