IM Attacks on the Rise
Just because you've deployed an enterprise-grade instant messaging (IM) solution
from a well-known vendor, doesn't mean you've mitigated -- let alone completely
licked -- the threat posed by rogue, unsanctioned or illicit IM use in your
Consider recent research from policy and risk management specialist Akonix
Systems Inc., which tracked more than 20 new IM attacks last month, a sharp
rise (more than 160 percent) from March.
Akonix is interested in such statistics because it markets a line of products
(including several appliances) that are designed to specifically counteract
IM-based attacks. As the increase shows, it's has been a busy month where IM
attacks are concerned. As late as April 30, for example, security researchers
identified three new IM threats, including a Trojan attack (dubbed Flocker.A)
that affects Symbian mobile phones.
The Symbian attack highlights the increasing sophistication and complexity
of IM attackers: They're no longer targeting specifically Win32 platforms. With
a growing number of IMers using non-traditional platforms (e.g., mobile phones,
iPod Touches), IT organizations must work overtime to cover all their bases.
Aknonix also tracked an uptick in attacks against peer-to-peer (P2P) networks,
a category that includes popular sharing services such as Kazaa and eDonkey;
P2P attacks were up 13 percent in April compared to March, according to Akonix.
Akonix researchers say the rise is due, in part, to enterprise IM use, particularly
because unified communications (UC) efforts are also on the rise. Organizations
are increasingly deploying next-gen IM and UC platforms, in some cases without
adequately testing -- let alone hardening -- these systems against outside attacks.
The result, Akonix officials claim, is a feeding frenzy for attackers.
"With this month's spike in IM attacks, hackers are continuing to penetrate
companies as they roll out instant messaging and unified communications platforms
for the new year," said Don Montgomery, VP of marketing at Akonix, in a
statement. "Enterprises need to realize that implementing new communication
and collaboration tools increases the risk of attack as each new application
becomes a new vector for infection."
Last month's increase in IM-related attacks is part of a larger trend. Aknonix
also flagged an escalation in IM attacks in February, for example, as well as
year-over-year rise for all of 2007. Last year, for example, researchers
discovered 346 new IM-related attacks -- nearly one per day. To put it into
perspective, that's more than the number of reported vulnerabilities for major
operating systems platforms such as Windows XP, Windows Server 2003 or even
It isn't as if the stakes aren't already high enough, either. Last year, for
example, a security consultant was sentenced to nearly 60 years in prison and
fined $1.75 million for using IM botnets to hijack PayPal accounts.
