Malware Spotlight Double Header: Bagle and Netsky.

For a reader special, we are taking a look at two pieces of malware, both of which are related in a way.

Bagle is a mass mailing worm which affects all versions of Windows. It opens a backdoor to allow hackers to access your computer and some variants contain the following text:


"Greetz to antivirus companies
In a difficult world,
In a nameless time,
I want to survive,
So, you will be mine!!"

Bagle also cereated a botnet which sent itself to other PCs via mail applications such as MS Outlook. It is estimated that Bagle was responsible for 14% of spam on January 1st, 2010.

Netsky is also a worm. It contained comments in the code of it that was meant to insult the writers of the Bagle worm. Some variants also played sound through the speakers of your computer at 5:00 AM each morning. So this would annoy you and depending on when you get up in the morning and how loud your speakers are, you could actually be woken up by this sound. This sound ceases at 9:00 AM and resumes again at 5:00 AM the next morning. This worm also spread by mass mailing itself to all your contacts.

Feel free to comment below if you have a question or you just want to tell me how awesome I am.
