tax-statement-taxpayer_id*.exe

There are some fake IRS spam mails circulating at the moment that go to a page and try to get you to download a virus file which trend micro office scan picks up as TROJ_ZBOT.CBY.

I am particularly worried about this email as it seems as though the URL contains the email address of the user it was sent to. This will then allow the owner of the site to log valid email addresses when someone clicks on the link in the email. They don't even need to download the file to now be a bigger target for spam.

Solution: I also noticed that there are multiple domains that users are being redirected to so I decided to block *.irs.gov.*.com on our Proxy server to prevent users getting themselves on a spam list.

I found the following domain names in this type of attack so far:

*.irs.gov.y11dera.com

*.irs.gov.fedas1am.com

*.irs.gov.fedasaz.com

*.irs.gov.y11derq.com

Facebook Phishing

I got an email from facebook that looked like a legit notification that one of my buddies have written on my wall. Except it was written in broken english:

"hello , howdy?? lisen i got a new friend here..shex kinda new here..maybe you can give her a lil tym so she can enjoy here?? not forcin u but u can chk out =)
It was followed by the following link:
http://www.facebook.com.profile.id.aymacc.2810ly6l.dortos.net/facebook/index.php?id=5aaz6677&auth=j5xp2&cyua=hwy9e1l821
It looks pretty legit at first glace, but if you take a close look you will notice that the domain is actially for dortos.net.
Whois information from whois.net

Now the thing that I found wierd was that when I logged into my profile on facebook I still got a notification about the wall post, but there was no post on my wall.

I cautiously opened the link to the fake profile and Firefox 3 Beta blocked it. (See screenshot)

I then decided to open the page up in IE8 and guess what. It looks identical to the facebook login screen. Except that it aint. (screenshot below)


This is a typical phishing attempt. I imagine that my buddy who sent the origional wall post recieved the same thing and his account was compromised. My personal information was then obtained through his profile and a wallpost was placed on my wall.

I am not sure exactly what is going on, but I recon there will be some information once the security researches around the world get a similar "phantom wall post".

I guess this is another reason to upgrade to Firefox 3 :P

Malvertising

It seems as though there is a new threat on the web .... MALVERTISING. (Malicious advertising).

Trend Micro:

"Surprisingly, users do not necessarily have to click on an ad to trigger a Web threat."

"viewers may be quickly redirected from the original site to a different site, which initiates a malicious adware download through browser vulnerabilities—a process known as drive-by-download."
