Stupid is as stupid does

If you’re on my Facebook friends list you’ll have got this message over the weekend

Hello All
If you’ve had a weird message from me (other than this one!) today please delete it
I got the same message from a friend and while allowing my curiosity to get the better of me i managed to infect myself
Highly highly embarrassed
Feel free to message me with abuse

So I thought I’d explain what I meant when I said I’d allowed my curiosity to get the better of me

On Saturday morning I got a message from a friend via Facebook. The English was terrible (the subject was – Gt you! Ha-ha, now watch and cr!) and the link certainly looked “dodgy”. I figured my friend had his PC compromised and it was sending messages from his Facebook account

It was the first time I’d seen this type of malware attack so I thought it might make an interesting blog post so followed the link

It took me to a page that looked like YouTube (if YouTube was broken!) and I got a message displayed telling me that my flash player needed updating and I was prompted to download a file

I downloaded the file and uploaded it to VirusTotal for analysis which then identified the file as being the “KoobFace” worm

Koobface.worm – McAfee

Win32.Worm.KoobFace.A – Bitdefender

W32.Koobface.A – Symantec

Koobface Family – CA

This was where I made a stupid mistake

In my attempt to select the file so I could delete it I inadvertently double-clicked the file and it ran

As you can imagine my language was colourful at this point

I got a message on screen

“Error installing Codec. Please contact support”

Using the information links above I managed to remove the main worm program and a browser add-in it had loaded to Internet Explorer (I’ve since flattened the machine and reloaded )

When I recently made the switch to Vista 64-bit as I was installing all my usual programs and thought it would be an interesting experiment to run without any anti-virus software (and blog about it here later!)

I’ve been running without any anti-virus since mid-July. I use some of the well known on-line scanners as well as some offline tools twice a week to check all is ok and until yesterday everything appears to have been fine

That said all the anti-virus software in the world can’t protect you from being stupid!

So what have I learnt from this debacle?

1) It may be a good time to end my experiment

2) I rarely allow websites to keep me signed in but Facebook had been an exception. I’ll be going back to how I usually run!

3) If you tell friends it’s ok to abuse you, then they will šŸ™‚

As a side note it looks like Facebook have been doing some work too. When I now click on the original link Facebook blocks the page with a warning the site is dangerous
