TrendLabs | Malware Blog - by Trend Micro - DefCon Las Vegas 2009
"TrendLabs | Malware Blog - by Trend Micro" - 1 new article
DefCon Las Vegas 2009DefCon in Las Vegas is probably the biggest event hackers and even non hackers have been waiting for. Although there were fewer people in this year’s DefCon (around 6,000, my estimate), the presentations, contests, and parties still raked in a huge number of attendees. The DefCon attendees believe that cybercriminals will likely be doing more of the same in the near future. Some techniques highlighted were:
Attacking datacenters was suggested as a new topic for next year’s DefCon. Datacenters can be attacked or exploited either physically (through lock picking) or digitally (hacking Hadoop, one of the most used database systems). I did not hear anything about distributed denial of service (DDOS) attacks on datacenters as this would only probably make sense in cases of blackmailing their customers. The fact that there was no secure OS was again reiterated. This was proven by the presentation on "Runtime Kernel Patching on Mac OS X," from which I gathered:
DefCon originated in 1993. It was a meant to be a party for the members of “Platinum Net,” a Fido protocol-based hacking network out of Canada. At present, it has become one of the oldest-running and largest hacker conventions around. This year’s DefCon was held at the Riviera Hotel and Casino in Las Vegas from 30 July–02 August.

iDefense Security Advisory 08.07.09: Adobe Flash Player Invalid Loader Object Reference Vulnerability
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hash: SHA1
iDefense Security Advisory 07.30.09
http://labs.idefense.com/intelligence/vulnerabilities/
Jul 30, 2009
I. BACKGROUND
Adobe Flash Player is a very popular web browser plugin. It is available
for multiple web browsers and platforms, including Windows, Linux and
MacOS. Flash Player enables web browsers to display rich multimedia
content, such as online videos, and is often a requirement for popular
websites.
For more information, see the vendor's site found at the following link.
http://www.adobe.com/products/flashplayer
II. DESCRIPTION
Remote exploitation of an invalid Loader object reference vulnerability
in Adobe Systems Inc.'s Flash Player could allow an attacker to execute
arbitrary code with the privileges of the current user.
During the processing of a Shockwave Flash file, an object can be
created, along with multiple references that point to the object. The
object can be destroyed and its associated references removed. However
a reference can incorrectly remain pointing to the object. The invalid
object resides in uninitialized memory, which the attacker may control
to gain arbitrary execution control.
III. ANALYSIS
Exploitation of this vulnerability results in the execution of arbitrary
code with the privileges of the user viewing the web page. To exploit
this vulnerability, a targeted user must load a malicious Shockware
Flash file created by an attacker. An attacker typically accomplishes
this via social engineering or injecting content into a compromised,
trusted site.
IV. DETECTION
iDefense has confirmed the existence of this vulnerability in latest
Flash Player version 9.0.124.0. Previous versions may also be affected.
V. WORKAROUND
A Internet Explorer plugin is available to temporarily block and unblock
Flash content using a single click. Only trusted sites should be
unblocked when using this plugin. More information is available at:
A Firefox plugin is available to temporarily block and unblock Flash
content using a single click. Only trusted sites should be unblocked
when using this plugin. More information is available at:
