Facebook exploits

Published by dave at 9:24 PM under computers | Current Threats | Malware | Internet | Daily Tips | Facebook

You may have read this week how Facebook had disabled a number of accounts of people in an attempt to weed out spam accounts (particularly targeting "female" user accounts).   In what appears to be an attempt to exploit the fact many legitimate accounts were inadvertently disabled, hackers have spammed an attack pretending to be from Facebook notifying you that your account password has been changed.  While there are a number of subject lines associated with the spam, they all carry a ZIP file with malicious payload known as Mal/BredoZp-B, and the Trojan horse contained within as Troj/Agent-PLG.

Once again this is an attempt to cause havoc through social engineering and deception.  Do not open the attached file or any attachment that seems suspicious.  Here is sample text of the email you may receive:

Good afternoon.

A spam is sent from your Facebook account.
Your password has been changed for safety.

Information regarding your account and a new password is attached to the letter.
Read this information thoroughly and change the password to complicated one.

Thank you for your attention,
Facebook Service.

Black Friday and the looming Google Instant Security threat

I have previously warned that "Google Instant" may pose serious risks.   Now news from Pandalabs of some serious malicious code that could well spoil your holidays ahead.

Though mundane, this is "Must Read" material.

The evolving “LinkedIn” threat

A couple of days ago I posted a warning about false communications pretending to be from LinkedIn.  That threat continues and evolves with a variation on the threat arriving in my email today.  See the screen capture below.  Everything about this email on the surface looks legitimate, except of course for the fact my name is not “Dawn”, nor am I expecting any payment from any of my LinkedIn connections.

As always, your best defense is your own common sense.  If anything arrives in your email that just doesn’t “smell right”, chances are it’s not right and potentially carrying a nasty payload just like the ZIP file attached in this email.

Always make sure your system has the latest critical updates from Microsoft.  Always make sure you have current AntiVirus and other malware detection systems active and most importantly, CURRENT and up to date with the latest threat definitions.  The Internet is a seedy place, browse safely and trust no one.

Today's Tip: Update to AntiSpyware XP2009

Last week I alerted you to a common trojan trap that is surfacing all over the web under a variety of names. AntiSpyware XP2009 is just one name. Rather than update the original post, I have decided to post this once again because of the EXTREME DANGER this type of threat poses.

A colleague of mine recently passed away. While searching for news about him, I navigated to a site where I was greeted by this pop-up window:


AV360 Pop Up


Pretty scary huh? It gets better. It matters not how you exit the pop-up message, as soon as you do, a fake "scan" animation is displayed that makes it appear your system is being scanned. It is important to note that the script is NOT PERFORMING A SCAN. What you see is only an animated webpage made to resemble an actual scan. A full size screen capture of this scan animation is displayed here
So how do we know the scan is a fake? Well for starters, the fake animation displays only 2 Local Disk drives and a DVD-RAM drive. In reality, there are 9 Disk drives on my computer and one DVD-RW drive. Secondly, while "local disk" is the name Windows assigns Hard Disk Drives during installatioin, I rename all my drives to unique names. It's a neat little trick that can help you spot these fake screens. Renaming HDD's to a friendly name will be the subject of a future post. And lastly, we know this is a fake screen because the layout is based on a Windows XP Explorer window, I'm actually using Windows 7 Beta on this computer.
Finally, take a close look at the final screen capture below:


AV360 Pop Up


Under no circumstances should you select the "OK" option to install. Clicking on the X, or the Alt-F4 keystroke combination just puts you in a repeated error message loop. Close the actual BROWSER window to cut this trojan off at the knees.
It's easy to be fooled by these tricks and a lot harder to clean up after, so surf smart. Don't panic when you see a pop up like this, but if you get taken in, call the St. George UT PC doctor for disaster cleanup.
