NEW YORK (March 21, 2001 11:45 p.m. EST http://www.nandotimes.com)
- The gravity of a flaw in the most popular software for sending
encrypted e-mail was questioned Wednesday by security experts.

The vulnerability in Pretty Good Privacy, disclosed by two Czech
cryptologists a day earlier, could allow a hacker to use someone
else's electronic signature to send messages.

That, in essence, could mean the forging of signatures
increasingly used to authorize such things as financial
transactions.

Philip Zimmermann, the creator of PGP, confirmed the flaw exists,
but questioned how useful it would be to attackers.

A hacker would first have to bypass security firewalls and gain
access to the recipient's hard drive. If a hacker can get that
far, Zimmermann said, the user has greater worries, including the
ability for someone to install software to monitor keystrokes like
passwords.


"60-70% of all attacks come from the inside" blah blah blah.  If we
are to beleive these numbers, which many of us see as accurate,
plus-or-minus whatever percentage that happens to tailor it to our
experiences, then it should be obvious that an intruder doesn't need
to bypass a firewall, he needs to stay late and access a machine
possible down the hall, or a few floors up.

-or-

A company rival may plant an after-hours maintenance worker in a
building... Where before only "encrypted data"  may have been stolen,
now the same data, plus the keys to it and anything intercepted can be
had.

But this isn't serious, no...

-aj.
