Conficker Discussion Part 2 – Even more stuff to talk about

Paul

We’ve heard in the[intlink id=”3214″ type=”post”] coming days there will be an update for the Conficker.C Worm[/intlink] and Microsoft has Released even more information about it: For Instance:
[ad#cricket-right-ez]

Win32/Conficker.C is a worm that infects other computers across a network by exploiting a vulnerability in the Windows Server service (SVCHOST.EXE). If the vulnerability is successfully exploited, it could allow remote code execution when file sharing is enabled. It may also spread via removable drives and weak administrator passwords. It disables several important system services and security products.(was reported to Microsoft on February 20, 2009.)

Win32/Conficker.D is a variant of Win32/Conficker. Conficker.D infects the local computer, terminates services, blocks access to numerous security related Web sites and downloads arbitrary code. Conficker.D can relay command instructions to other Conficker.D infected computers via built-in peer-to-peer (P2P) communication. This variant does not spread to removable drives or shared folders across a network (as with previous variants). Conficker.D is installed by previous variants of Win32/Conficker. (was reported to Microsoft on March 4, 2009.)

As you can tell, this seems to be two different Variants starting to emerge.  Now let’s go a little bit more deeper shall we.  According to US-CERT(United States – Computer Emergency Readiness Team) , They claim that this is Widespread infection and have posted about it on there website TA09-088A.

My one questions is Why is the US getting ready for this Conlicker worm, are they worried that what happened to the Parliament will happen to some branch of the White House.  This seems to be an even more hype building over this worm.  Everyone will tell you the same thing, they are not sure what will happen on April 1, 2009.  I think it will be a normal day and all because with all news about the Conficker worm, the person who wrote this won’t want the light shined on them before they get there foot hold in systems.  So you will most likely not notice anything special on April Fools day due the awareness of the worm.

But don’t forget to update your [intlink id=”2205″ type=”page”]Anti-virus software[/intlink] and also might be time to add a good [intlink id=”2205″ type=”page”]free firewall to help protect yourself[/intlink] from this worm.

What will happen on April 1? Conficker discussion!

Paul

I saw that F-secure has posted what a Question and Answer on the Conficker Worm.  I wanted to talk about this a little myself:

Q: I heard something really bad is going to happen on the Internet on April 1st! Will it?
A: No, not really.

Q: Seriously, the Conficker worm is going to do something bad on April 1st, right?
A: The Conficker aka Downadup worm is going to change it’s operation a bit, but that’s unlikely to cause anything visible on April 1st.

[ad#cricket-right-ez]I am like everyone else, I really don’t know what will happen it is always going t to be media exposure when it comes to Worms, Viruses, or Trojans.  Virus Writers whoever “THEY” are, will always want to update there infected systems to keep the virus(Also worms, and Trojans) on peoples systems.   This is the way of security firms will always have to predict them, keep up with them, or just follow them.  This will never  change because as virus writers want to find even more ways to infect systems that is the necessity of Anti-virus Software.

I don’t know what will happen on April 1, you most likely will be fine if not you won’t know it until you try to update your system or update your anti-virus software.  One way you can find out if your infected is by trying to serf to security vendors like F-secure, Norton, and Kasperky.  If you Can’t get to those sites then you most likely have a Virus or Worm, and it could be this worm!!

  1. Make the worm harder to detect — This is a common practice they want to be able to hide the worm for as long a possible.  So they will always tweak it to make it that much hard to detect and remove.

  2. Make the Worm easier to infect systems —  This is another common practice, because without having systems there is no need for a Command and Control server.  The worm could do things such as Denial of Service, Or send out spam, or steal sensitive information.  This is the nature of why people make viruses, Trojans, or Worms.

  3. Easily update the virus software — as with any software the virus writers will come up with easier ways of updating the software, because the security will do whatever they can to prevent the update.  This is also the nature of why there will always be updating of the code.  They will put in more ways to keep the virus, worm or Trojan from being blocked.   Like the Conflicker has some Peer to Peer functionality, so if one company blocks the update another way it could get the update is Peer to Peer.  So you can’t block it very easily.

So what will happen April 1?  Who knows it could be a normal day, or it could be the biggest [intlink id=”3208″ type=”post”]April Fools joke[/intlink] ever.  That is why I put that in my last blog post.  With so much Media Frenzy the security firms don’t know what the Worm will do when it updates, all they can do is wait.   So let’s take a deep breath and relax, there’s nothing we can do just yet!!

The April fools Joke, You’ve got a computer worm!

Paul

Cluely’s blog talks about this and I thought I would talk about it a little myself!!

[ad#cricket-right-ez]This is the newest version of the Conflicker/Downadup variant of the little worm.  There seems to be people who are worried that April 1, there will be a major wake up in security no holds bar problems.

Some people have got rather confused as to what the April 1st deadline really means. The truth is that Conficker is not set to activate a specific payload on April 1st. Rather, on April 1st Conficker will begin to attempt to contact the 50,000-a-day potential call-home web servers from which it may receive updates.

[Via Graham’s Cluely Blog]

Now let’s talk about this a little, this worm won’t do anything else but ask for updates on April 1, and we don’t know when the virus writers will implement the update it could be a month down the line.  You could[intlink id=”3171″ type=”post” target=”_blank”] Backup[/intlink] your software and use the free program [intlink id=”2883″ type=”post” target=”_blank”]Autopatcher[/intlink] to help make sure your system is completely up to date with windows security.  You can’t forward the to that date to find out what will it call home to.    We don’t know what it will do when they update to the conficker.c program all we know it starts to try to call to certain domains on April 1, 2009.  So you should install [intlink id=”2205″ type=”page”]Anti-virus and Firewalls[/intlink] where you think it is needed.

I am sure though this will be an really big April Fools Joke from the Virus Programmers, they will be laughing at the hysteria of people trying to find out all the important information on April 1, and yet it might not start to happen until much later!!  You are the first line of defense from getting a virus or any malware.  So let’s keep our heads on straight and not go over board!  Only time will tell, and I am sure what happens on Apr 1, 2009 will be a new day.


Zero Day For IE7 Being used in the wild.

Paul

It looks like IE7 patches are being used right now in the wild.  According to TrendMicro:

HTML_DLOADER.AS exploits the CVE-2009-0075 vulnerability, which is already addressed by the MS09-002 security patch released last week. On an unpatched system though, successful exploitation by HTML_DLOADER.AS downloads a backdoor detected as BKDR_AGENT.XZMS.

How the IE7 Exploits are being used

[ad#ad2-right]As you can see this this can be very bad for the companies who wait a while.  Internet Explorer is still being used 1 out of 4 users and I see it it all the time on my stats.   The Good news is this isn’t as hard to get rid as the Conflicker but should be taken serious because the writers might start to want to get even more malicious and make it even harder.

This is the next step to prevent yourself from getting caught with your pants down so to speak, you need to patch all systems that have internet access.  I still like the Autopatcher because it will do the job with very little input from the user.   It also makes it easier for people to patch big systems.  You should also consider installing some Free Anti-virus software to help protect the systems you do have.

From the looks of this virus, someone could easily make this into a botnet and you know how that can could affect your systems and your ISP.  So it is best to get this months patches on the floor of your company as soon as possible.

You should also consider telling your users to start using Firefox to prevent infection from even happening. Until you patch, you are vulnerable.
