Security Experts Say Terrorists Likely Used Internet

Yahoo, 9/21/01
<a href="http://dailynews.yahoo.com/h/ksat/20010920/lo/910762_1.html">http://dailynews.yahoo.com/h/ksat/20010920/lo/910762_1.html>

Security experts who daily keep their eyes on the Internet for security
weaknesses say that terrorists could have effectively communicated with
each other with encrypted messages over the Internet. 

Security experts say that Osama Bin Laden likely had access to enough
sophisticated technology to have used the Internet as part of the
coordinated strikes against the World Trade Center and the Pentagon
(news - web sites) on Sept.  11. 

San Antonio-based SecureInfo Corp.  provides security intelligence and
vulnerability information to the government, health care and financial
sectors. 

"I'd be surprised if people, terrorists, weren't using some kind of
mechanism to protect their info when communicating what their plans
are," Director of Communications Fred Ramirez said. 

Ramirez said that there are several encryption or code-like techniques
that could be used to disguise messages. 

But tracing them isn't easy. 

"You have a 100,000 people there, and you're trying to pick out a
conversation between two individuals, and they're not even speaking
English," Ramirez said. 

Making the investigation even more complex is that security experts
believe that public computers like those in libraries or at Internet
cafes may have been used. 

The FBI (news - web sites) is seizing computers from all over the
country they believe may have been used by alleged terrorists. 

They also believe that terrorists may have communicated by hiding
messages inside pictures on pornographic Web sites.  Security experts
say that that can be done because digital information makes up a
computer image. 

For example, an image is really a computer code made up of ones and
zeros.  Imbedding a message inside of those numbers is easy for those
who know how to do it, Ramirez said. 

"It's a lot of sites out there, like that, people don't really care what
could be imbedded in them," he said.
