This page contains indexes of four periodicals
published by the National Security Agency, plus a listing of publications
from the NSA's Center for Cryptologic History. These indexes haven't been
publicly released until now, and many of the Cryptologic History publications
weren't previously known to the public. Researcher Michael Ravnitzky has
discovered a huge cache of information about the NSA, intelligence, and
cryptography.
During the initial testing of Greylisting
in mid-2003, it was observed that the vast majority of spam appears to be sent
from applications designed specifically for spamming. These applications
appear to adopt the "fire-and-forget" methodology. That is, they attempt to
send the spam to one or several MX hosts for a domain, but then never attempt
a true retry as a real MTA would. From our testing, this means that in the
test environment, based on a fairly conservative interpretation of testing
data, we have attained an effectiveness of over 95%, and that is with no
legitimate mail ever being permanently blocked.
Targus might consider employing engineers that actually
understand the most basic
methods of defeat. If in fact they do possess such competence, then they
are oblivious to the security needs of the consumers that rely upon them to
secure their laptops. But, then, Targus does not guarantee the security of
these products, just their workmanship to be free from
defects.
As you probably have heard, British authorities have arrested 24 suspected
terrorists who are alleged to have planned the bombing of 10 US-bound
airplanes using binary agents
disguised as beverages and a trigger disguised as an MP3 player.
Consequently, authorities are moving to ban all kinds of liquids and gels in
carry-on luggage. As with their plans to confiscate nail files at the
security checkpoint, but not the nail files on sale in the boarding areas,
they get an "A" for effort, but "F" for execution.
It turns out the TSA's
solution is to just pour all suspect liquids into one big garbage can near
the crowd of people queued up to pass the checkpoint. Brilliant! This is
right up there with the TSA agent who arguably illegally
searched John Perry Barlow's luggage and found marijuana when she
shook and then opened an ibuprofen bottle she claimed was a
suspected bomb.
I'm not sure which is more dangerous, these attempts to provide a false
sense of security, or the other attempts to instill a false sense
of insecurity.
The bar for talks is so low at DefCon, that even the lamest of
talks was rendered mediocre by those around it. And a two-hour hold up on day
1 ensured a frustrated day for most everyone involved. Come on, Slashdot, the
war rocketing talk could have been done in 5 minutes. And how many possible
times can you see someone explain how to use Ethereal in one weekend? Six,
evidently.
This year's controversial presentation at Black Hat was won by
Device Drivers: Don't Build a House on a Shaky Foundation. In their
demonstration (recorded before the conference to prevent attendees sniffing
their attack technique) , johnny cache and David Maynor show the remote
compromising of a wireless laptop by exploiting flaws in the software used by
the operating system to drive the device. To sex things up, the laptop they
compromise is a MacBook.
See, David Maynor has a bone to pick with Mac users who have bought into
and perpetuate the myth that Apple software is more secure than Microsoft
software. In an attempt to prove them wrong once and for all, Maynor slaps a
third-party wireless device on to the MacBook and goes to town. "But wait!"
those same Mac users cry, "He didn't demonstrate the attack with Apple's
wireless driver, it's just the third-party driver!" Mr. Maynor defends the
demonstration by claiming that the attack does work with Apple's driver, but
that Apple pressured them to not show that because Apple hasn't released a
patch yet.
Now, I'm willing to assume this is all true, but what do we really know?
At the end of the day, nothing, really. They haven't released details to
reproduce, third parties haven't released patches to reverse engineer, and no
one has publicly disclosed a rediscovery of the flaws. We might as well
assume that the demonstration was recorded on the same sound stage that NASA
used to fake the moon landings! Kidding aside, the only take-away from their
presentation is that device drivers are not immune from security bugs, which
shouldn't come as a surprise to anyone... though it probably does.
None of this is to say that Apple software is more secure than Microsoft;
the publicly disclosed vulnerabilities and security updates are testament
enough to disprove the myth. The problem is that, while I wish folks like
David Maynor well in their pursuit of humbling the hubristic, there are none
so blind as those that will not see.
