Phishing attacks focus on AOL and AOL Instant Messenger users

Filed under Uncategorized

The latest phishing campaign I have been seeing targets users of AOL Instant Messenger.    Users are sent an e-mail with a subject line reading something like “Your AIM account is flagged as inactive”.  If you open the message, the body of the email will read somehting like this:

Dear AOL Instant Messenger (AIM) user,

Your AIM account is flagged as inactive. Within the following 72 hours it’ll be deleted from the system.

If you plan to use this account in the future, you have to download and launch the latest update for the AIM. This update is critical.

In order to install the update use the following link. This link is generated exclusively for your account and is available within a certain period of time. As soon as this link is not available anymore you will get another letter.

Thank you,

AIM Service Team

Of course, downloading and running the application at the linked site merely installs a Trojan, which makes your computer a part of a bot-net and can be used to steal you personal and financial information.

Microsoft IE Patch

Filed under Uncategorized

Happy New Year!  Yes, I know the New Year is almost a month old, but since this is my first blog post this year, I thought I would say it anyway.

Now to the important stuff.  There was a new bug discovered in Microsoft’s Internet Explorer.  This bug was considered to be such a serious security hole that they took the unusual step of issuing an “out of band” hotfix – meaning that they issued it right away, rather than wait until the normal Patch Tuesday release.

According to SC Magazine:

Microsoft on Thursday delivered an emergency patch to correct seven Internet Explorer vulnerabilities, including at least one known to have been used in the highly publicized attacks against more than 30 brand companies.

Microsoft was forced to acknowledge the flaw last week, when McAfee reported that an IE exploit was one of the malware samples being used to spread data-stealing, espionage trojans to Google, Adobe, Northrop Grumman, Juniper and more than 25 other large companies.

If you have your home PC set up to automatically download and install updates, your system should be protected.  However, if you like to manually install updates, you should download and install the update as soon as possible.

There are some reports that this vulnerability is what was used by hackers to compromise the GMail accounts of Chinese dissidents.  However, that attack was accomplished using a piece of malware called the Hydraq trojan.

As always, keeping your system updated and your anti-virus current is your first line of defense.
