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

AutoRuns

Ever wondered why your computer is taking forever to start up? Well then AutoRuns is for you! This is the most comprehensive application that I have seen for killing automatic processes. I think I am going to be using AutoRuns a lot in future! I love sysinternals!

Sending Emails From CMD

I was recently asked to write a script to check if a file exists and then email someone if the file is found. I found this program called Blat. Blat is a command line email client. basically all I did to get it working was download and copy blat.exe and blat.dll to %SystemRoot%\System32.

Check the code below:

@ECHO OFF
REM ### CONFiGuRE SETTINGS HERE ################
set SMTPServer=127.0.0.1
set ToAddress=email@mydoamin.com
set fromAddress=email@mydomain.com
set Servername=My Server Name
set find="C:\myfile.txt"
REM #####################################
IF EXIST %find% (goto senderror)
goto end

:senderror
set Subject=File Found
set MessageBody=%ServerName% -File Found. (%Date%)
%SystemRoot%\System32\blat.exe -server %SMTPServer% -f %fromAddress% -to %ToAddress% -subject "%ServerName% - %Subject%" -body "%MessageBody%"
goto end

:end
@ECHO ON

Google Chrome OS

Google announced Google Chrome OS recently. It seems as though Google is again pushing cloud computing. The net-book revolution is the next thing in computers with all the major players starting to take notice. Ever since the Asus EEPC was launched a while back people have begun to sit up and notice. Intel is currently also in the race as they have started developing an operating system specifically for net-books.

I do think that Google once again has the advantage as they are the ones who have all the cloud applications already. With Gmail, Google Docs, Calendar and more already pretty stable they are more than ready to give the world a taste of cloud computing. And now with the announcement of their own net-book OS that comes with Google Chrome they will be able to run all of their applications in a browser specifically designed to run those applications as fast as possible.

I can’t wait to see what they come up with.
