Banks are not the only target for phishing

September 12, 2008

It’s not just banks that hackers deploy phishing attacks against; it has been seen that hackers also deploy attacks against other payment processing services such as MoneyGram, Equifax, Western Union, etc as a way of gaining profit through harvesting personal details.


Attack of the Southwest Airlines Malware

September 11, 2008

There is another round of spam messages claiming to be a ticket receipt for Southwest Airlines. The message attempts to entice the user into opening an attachment containing the electronic ticket which is actually malware classified as W32/Autorun.AEL.worm. The ploy here is the note that the ticket reservation system has changed and that an account has been created.


Fake Antimalware Applications

September 8, 2008

As we have been monitoring the threat landscape during the last couple of weeks we have noticed an increase in fake anti-malware applications being used to defraud users. While these applications themselves do not provide any level of security for the user in terms of detecting and removing malware; the application itself is designed to trick the user into thinking that they are infected via the use of pop-ups and enticing them to purchase a full version as a means of cleaning the system.

The objective is always financial motivation and this is one way they are making money by sending out Spam with Trojan downloaders hidden behind the links designed to install fake security software, in a majority of the cases Anti-virus XP 2008.


New Celebrity Spam – Fake Security Product Installed (AV XP 2008)

August 28, 2008

This morning the Celebrity spam campaign continued with a few new fake video codec sites delivering a downloader Trojan designed to install a fake security product known as AntiVirus XP 2008. It’s apparent now that a number of these spam campaigns are only interested solely in distributing this one particular fake security product. The file downloaded is called video99.exe or video66.exe and varies depending on the email message and the site used (HTML page names often correspond to the binary used index99.html, index66.html, etc).

Some of the subject lines of this particular spam campaign is:

“John McCain to Paris Hilton: Cosmo, baywatch!”

“Britney Spears Shaves Head at Request of Zombie Overlord”


Fake Windows XP Vista Update – Installs AV XP 2008

August 28, 2008

This morning the AV XP 2008 spammers were at it again with another round of spam messages claiming to offer an update to Microsoft Windows Vista (we have seen similar attacks before offering false updates). However, when the user clicks the link he/she is directed to a malicious .swf that will download the file install.exe which essentially is a downloader Trojan designed to install AV XP 2008.

Statement of Fees Malspam Campaign (AV XP 2008)

August 28, 2008

A couple of minutes ago another round of spam messages appeared claiming to provide information concerning a statement of fees recently posted (inferring to banking account fees). The message contained an attachment with a fake Microsoft Word Document which actually is an executable (Fees-2008_2009.doc.exe) that installs a Trojan Downloader.

Further analysis indicates that the Trojan when installed connects to a php page hosted on a Russian domain to obtain several possible sites as a means of downloading the installer for AntiVirus XP 2008. The actual URLs are contained within this script and the file which is downloaded is lspr.exe (MD5 ffccd0518b04354532c733674c0faa00) and is identified as Adware/AVXP2008.
