Ping....It's Spim Chatting
As the term indicates,
spim is a type of spam distributed via IM (instant message) instead of traditional
email. The trend really began to pick up
in 2003 when more than 500 million unsolicited advertisements were sent through
instant messaging systems. As this
technique becomes more relevant in the world of online business, spim has wasted
precious resources and created additional security issues.
Why your IM is so attractive to spammers
Spammers have found that
instant messaging is a very rewarding platform for their efforts. The immediate nature of communication makes
recipients more apt to access the links provided merely on human instinct. Aside from that, many anti-spam filters and
firewalls are unable to detect spim, enabling its senders to bypass a user's
security and not only distribute their advertisements, but viruses and other infections
as well.
The growing level of spim
has led individual users, internet service providers, and the government to
unite in the never ending battle against spam.
As more regulations are set in place to reduce the effectiveness of
email spam, it is believed that more frustrated senders will inevitably turn to
instant messaging as their vehicle of distribution.
Spammers have targeted
some of the most popular instant messaging systems including Yahoo! Messenger,
AIM, MSN Messenger, Tencent and ICQ.
These programs draw so much attention because they offer an extensive
directory of users with details on their location, age and gender. Spammers can easily access this sensitive
data, log into the instant messaging system, and initiate their onslaught of
unsolicited ads. Spim has raised so much
concern that Microsoft has stated that the next release of their Windows Live
Messenger application would support new features to address IM spam.
Protection Against
Spim
While spim is quickly
becoming a huge problem, you can protect yourself by blocking any incoming
messages that originate from users not found on your buddy list. You can also configure your IM to only accept
messages from those on a special permission list. Here are a few tips to help you make the
adjustments in some of the most widely used instant messaging applications:
- AOL Instant Messaging - select the
"preferences" tab at the bottom left of the program window. From that menu, select "Privacy" from
the list of categories on the left side.
Navigate through the available options and enable the function that
reads, "Allow only users on my Buddy List."
- Yahoo Instant Messaging - beneath
the "Login" screen, select the "Privacy Settings" tab. Next, select "Ignore any user not on my
Friend list."
- MSN
Messenger - from within the "Tools" menu, select "Options." Then choose the "Privacy" tab in the
following menu. Now check the box
that reads, "Only people on my Allow List can see my online status and
send messages."
Here are a few more measures
that can be taken in the fight against spim:
• -
XP users should always upgrade their operating systems
with the latest service pack.
•
-Vulnerable systems should always upgrade to the most
recent operating system software, whether the environment is Windows-based or
an alternative.
•
-Implement firewall applications to block out packets
form intruders.
•
-Cancel your IM service or simply delete its execution
file from your computer.
