Peek-A-Boo: A method to remove virus out of your USB drive without getting infected!

Scenario: You have a USB drive in your hand and are scratching your head as to insert it into your PC or not ( the style of to-do-or-not-to-do) . Because you know it has viruses and you cant format it also because of the all important data. So this is where i step in or rather this post steps in. (It has legs, mind you)

OK. I will make all the work easy for you. Just follow the following steps.

First Download TREE SIZE PROFESSIONAL from the publisher site.

OR Download TREE SIZE PROFESSIONAL from CNET

The above mentioned software shows the space usage of your drives in graphical format.

As you know viruses get activated when you access the USB drive. But if TREE SIZE accesses the USB drive then virus is not activated.So i thought of playing a peek-a-boo and catching the virus unawares( not in your hand, of course) by exploring the space usage and then delete it.

So after you install right click the USB drive and see the listing. You will see a screen like this.

Now you can identify the virus, provided you know before hand what files were there in your pendrive.

Now delete the virus by right-click-the-file-and-delete .

Orkut worm feeds on scraps

From social networking to social engineering

Malware authors have written a worm for Orkut, Google-owned networking site that's big in Brazil.

The Scrapkut worm uses active code injection to spread between victims and their friends on Orkut. The malicious code appears on a victim’s scrapbook, containing a link to a supposed YouTube video.

People who click on the link are redirected to an external site hosting malware that's disguised as a Flash upgrade. Users duped into installing the software get malicious Javascript code injected into their next active Orkut web session. This malicious scrapbook entry is then sent to all the victims' friends, recommencing the infection cycle.

An analysis by Symantec can be found here.

Judging by the counter on a web page associated with the malware (not the most reliable of indicators) about 13,000 users are already infected by the Scrapkut worm, which isn't - for now - doing anything particularly nasty other than spreading.

By contrast an earlier worm that spread across the Orkut network last December infected an estimated 655,000 people. Google plugged the cross-site scripting (XSS) error that made the attack possible hours later, thwarting tfurther propagation of that fast-spreading worm.

YouTube fake tool dumbs down malware distribution

Nothing on the internet is real, man

Miscreants have created a tool that dumbs down the process of using fake YouTube websites to spread malware.

The YFakeCreator tool allows budding VXers to set up a fake site and configure options such as the properties of a supposed video. Typically users are required to download a fake codec to view content, which is not actually on offer. The codec contains the malware payload which can be anything from adware to a Trojan.

The tool also includes the ability to set-up a fake error message in a bid to disguise any attack.

Would-be virus writers would still need to mount a spam campaign in order to dupe prospective marks into visiting sites created by YFakeCreator, but the tool does reduce the overall work needed to mount an attack.

The tool was spotted by net security firm Panda Security which has published a full write-up, including screenshots of the tool, here. Panda discovered the tool on underground hacking forums.

YFakeCreator is far from an isolated example of tools that remove the need to understand coding from the task of malware distribution. For example, Panda found a tool that can turn any executable file into a worm on underground forums back in June.
