1. SECURITY
1.1 OS X - Remote Hacker Manual Control
-- Products Affected --
OS X
-- Technical Description --
What appears to be a variation on the Oomp / Leap script
hiding mechanism has been identified as affecting Safari, Mail and
manual extraction of archives. This could lead to unexpected
execution of scripts if Safari is set to automatically open 'safe'
files after download, or on double click of a file with a custom icon
(icon for a jpg replacing that for a Terminal script).
-- Description --
It has been discovered that scripts designed to run in the
Terminal can be automatically run if the 'open safe files' option is
selected in Safari. It is also possible to trick users who have
manually opened the archive into executing the script, through the
use of a custom icon. The advice given in the recommended action
section is considered the best available at this stage to mitigate
the effect of this vulnerability.
-- Recommended Action --
If it hasn't already been deselected, uncheck the 'open
safe files' option in Safari's preference pane, apply caution to
downloaded archives, avoid use of the Administrator account for
everyday actions

2. NEWS
2.1 Antivirus Company More Dangerous Than Infection
Following the recent announcement of the Oomp / Leap and Inqtana
worms for OS X, most Antivirus companies that have OS X products
updated their software to detect these latest worms. Unfortunately
for one company, their product was a little over-eager, detecting a
large number of false-positives (safe files which are mis-classified
as infected) and deleting them. Unfortunately, the files being
detected were critical for the operation of other applications, so
the fix has led to a greater risk than an infection would have ever
been.
2.2 Identity Breaches Moving Closer
Public reporting of identity data losses is moving closer to
Australian shores. It was recently revealed that several thousand
students associated with Canterbury University in New Zealand had
potentially had their personal data exposed for an unknown period of
time. Over the weekend it was discovered that people accessing the
University's online student system could view private data on any
student. While the attack requires some level of intent, it is
possible to completely compromise a student's identity based on the
information the system made available. The system has since been
taken offline, and it is not known when it will be made available
again. The timing of the discovery couldn't come at a worse time for
the University, with classes soon to commence for the new academic year.
2.3 (ISC)2 Accused of Plagiarism
The organisation which manages the CISSP certification, (ISC)2, has
been accused of outright plagiarism with their 'Official (ISC)2 Guide
to the CISSP Exam' book, which is claimed to contain numerous
sections that have been directly plagiarised from multiple sources
without attribution. Examples of the claimed plagiarism have been
published online, which drew a defense from one of the editors of the
book. The defense did not actually address the claims of plagiarism
- choosing to point out, instead, that there is rampant plagiarism
within the industry, and they are not the only ones to do it.
2.4 BP Plunges Off the Deep End
Energy giant, BP, has taken the odd move of moving 18,000 corporate
laptops out of the company LAN and onto direct connections to the
Internet. Concerned at the increasing attacks from criminal
interests, the company has moved the laptops out of the corporate
network in an effort to protect their internal systems. Most
observers have concerns over this move, claiming that it is more
likely to lead to a major incident than the previous setup. The move
means that each laptop will need to be individually hardened against
attacks (which means against known attacks), and instead of a handful
being directly connected to the Internet, they all will be. This
massive increase in exposure brings a commensurate risk, which
doesn't really appear to have been addressed very well.
