Warning! - Image-based Spam
Outfoxing Some Filters![]()
Disreputable
marketers are increasingly using a new strain of spam that's cleverly attempting
to sneak by spam-filtering software. Called image-based spam, it embeds messages
in attached, randomized .gif or .jpg image files and these images are changed
each time a message is sent. The difference in each image may be just a change
in the border or the variance of one pixel, but it's enough to get past
traditional spam filters that analyze keywords. Like traditional text-based
spam, image-based spam often includes pitches for things like pharmaceuticals
and penny stocks.
According to research released by security gateway
provider IronPort, image-based spam has increased twelve-fold in the past year.
It now accounts for over five billion messages per day and 78 percent of this
spam passes through first- and second-generation spam filters. The company
estimates that about 30 percent of spam delivered to an individual's inbox is of
this type. And it can be more than just annoying. Image-based spam eats up space
and create storage problems because each message can be up to seven times larger
than text-based spam.
Another factor that's led to greater volumes of
spam being sent around the globe recently is the increased number of zombie
computers — infected PCs that have been hijacked by spammers for their own use.
Spammers rotate through zombie networks every few hours, constantly changing the
IP address of the source of the spam in order to evade detection. CipherTrust, a
leading message security company, reports that they identify nearly 250,000 new
zombies each day, and it's estimated that 80 percent of today's spam is sent via
zombie computers.
Rest assured that we continue to implement the very
latest spam filtering techniques to stay a step ahead of the "bad guys" in the
ever evolving battle against spam. We appreciate our customers doing their part
in protecting their computers by using firewalls, receiving and downloading
system software upgrades each month from Microsoft, Apple, etc., and installing
and then regularly updating their anti-virus programs. Together, we'll continue
to win this war.
Deadly Virus Hits Internet!!! - Real or Hoax? - From Michael Sharer,
PSC Tech Support![]()
The next time you
get a message warning you of a deadly virus or cautionary tale (for example, "be
careful, terrorists are hiding HIV infected needles in telephone booths!"), take
a moment to check out the validity of the warning. An excellent site to do
this is "Snopes.com - Rumor has it..." (http://www.snopes.com). The Snopes.com
website lists thousands of "warnings" for viruses, scams, and other
"information" that is passed along through email.
So the next time you get
a warning advising you to "send this email to everyone you know!", take a moment
and make sure you're sending out something worthwhile, not just falling for an
Internet prankster's joke.

Ask The Help Desk - Stop The
Wrong Links From Loading
Question: If I accidentally click the wrong link on a
webpage, do I have to wait for this page to fully load before selecting the
correct link or can I "bail out" sooner?
Answer: Good news —
there are two easy escape routes to take when you realize you've clicked on the
wrong link. Which one you use depends on where you are in the selection process.
If you've clicked the wrong link and still have the left mouse button
pressed down, just drag your pointer off the link to a blank spot on your screen
and release. Problem solved.
If you've already released the left mouse
button, just hit your Escape key ("esc") on your keyboard. This will stop your
browser in its tracks and the page will not continue to load. It will also
prevent those pesky pop-up windows from appearing.
