--Mac App Store Will Require Sandboxing Support as of March 1, 2012
(November 3 & 7, 2011)
Starting next March, applications submitted to be sold through Apple's
Mac App Store must support Apple sandboxing. The deadline, which was
announced in June, was initially slated for this month. Sandboxing has
been voluntary until now. Some developers say that the requirement is
going to prevent them from incorporating certain features into their
applications.
http://news.cnet.com/8301-1009_3-57318099-83/what-apples-sandboxing-means-for-developers-and-users/
http://news.techworld.com/applications/3316380/developers-fear-app-store-sandboxing-to-strip-out-useful-features/
[Editor's Note (Pescatore): Given the success of mobile platforms like
the RIM Blackberry and the Apple iPhone/iPad, where one vendor controls
both the hardware and the software, there is a major opportunity to move
away from the old types of malware that plagued the PC. If doing so
breaks some features, that's a good thing - users are willing to lose a
few features to not have to worry about applications blowing up in their
faces every time they click on something.]
--FBI Says Using Fake Cell Tower is Within Their Purview
(November 3, 2011)
Federal authorities maintain that their use of a fake Verizon cell phone
tower to conduct surveillance on a suspect can be considered a
legitimate search under the Fourth Amendment. The spoofed tower device,
known colloquially as a stingray, was used in a case involving an
alleged identity thief. Stingrays conduct a man-in-the-middle attack,
intercepting crucial mobile device data before transmitting it to a
legitimate cell phone tower. An affidavit submitted by the FBI's
tracking technology unit says that the stingray harvests only the
equivalent of header data, and thus does not require a search warrant.
The affidavit goes on to say that the stingray also collects the data
from other devices in the same general location as the target, and that
FBI policy requires that all data stored in the tool are purged once an
operation has concluded.

--The Significance of Naming Names
(November 7, 2011)
The report released last week by the Office of the National
Counterintelligence Executive "mark[ed] the first time the United States
government has unequivocally stated, in emphatic and highly publicized
fashion, that China and Russia are responsible for a pervasive
electronic campaign to steal American intellectual property, trade
secrets, negotiating strategies, and sensitive military technology."
Journalist Shane Harris writes that "the release of this report may turn
out to be the Internet's iron Curtain moment," comparing its effect to
that of Winston Churchill's 1946 address.
http://www.washingtonian.com/blogarticles/people/capitalcomment/21474.html
[Editor's Note (Pescatore): Actually, many *are* trying to equate this
to the Iron Curtain/Cold War, hoping that the same types of budgets and
spending will occur through overhype. This focus leads to $5,000
coffeepots, not higher levels of security.
(Northcutt): I tried to read this, but it wanted me to subscribe to the
Washingtonian magazine first. Here is a USA Today version:
http://www.usatoday.com/news/washington/story/2011-11-03/china-russia-cybersecurity/51065010/1
I do not think this will become an Iron Curtain moment:

--US Supreme Court to Hear GPS Tracking Forth Amendment Case
(November 7, 2011)
The US Supreme Court will hear arguments on Tuesday, November 8, in a
case regarding the authority of law enforcement officers to
surreptitiously place a GPS device on a vehicle to track a suspect's
movements without obtaining a probable cause warrant from a judge. The
government has argued in court briefs that "a person has no reasonable
expectation of privacy in his movements from one place to another." The
specifics of the case involve Antoine Jones, who was convicted and
sentenced to life in prison for dealing cocaine. Police had tracked
Jones for a month through a device they had affixed to his car. Jones'
conviction and sentence were overturned by the US Court of Appeals for
the District of Columbia, which said that the tracking was tantamount
to an illegal search that violated Jones' Fourth Amendment rights.
Other federal appeals courts have ruled that a warrant is not needed for
GPS tracking. The Justice Department views GPS devices as being
equivalent to the beeper devices that were used to track vehicles
decades ago. The man who is credited for inventing the GPS has written
an amicus brief, saying that the two devices are very different.
http://www.wired.com/threatlevel/2011/11/gps-tracking-flourishes/all/1
[Editor's Note (Liston): Generally, I tend to always land on the "Fourth
Amendment" side in these types of cases. However, in this situation, I
really don't see how GPS surveillance is doing anything more than simply
replacing an officer being assigned to follow a suspect, something for
which a warrant is not required.]

THE REST OF THE WEEK'S NEWS
--Dutch Telecom KPN Halts SSL Certificate Issuing
(November 4, 6 & 7, 2011)
A Dutch telecommunications company has ceased issuing SSL certificates
after discovering that the site through which the certificates are
purchased had been compromised. A KPN spokesperson said that the
certificate generating infrastructure appears not to have been affected,
but an investigation has been launched. It appears that attackers may
have placed tools used to launch distributed denial-of-service (DDoS)
attacks on a KPN server; the attack may have taken place four years ago.
KPN is the Netherlands' largest telecommunications company.

http://www.theregister.co.uk/2011/11/04/ssl_still_hopelessly_broken/
[Editor's Note (Murray): If a 512 bit RSA Key is the weak link in your
security, you are very secure indeed. We use bigger keys because we
can, not because we need them. Take security advice from cryptographers
only after you act on their medical advice.
(Honan): A Certificate Authority that has been compromised for 4 years
and another that is issuing insecure certificates clearly demonstrate
that the trust model we currently rely on is in need of an urgent and
major overhaul. We need to have better standards of security that CAs
must adhere to and be independently verified or we need to quickly look
at alternative solutions.]
--Browser Makers Revoke Trust for Malaysian Intermediate CA SSL Certificates
(November 4, 2011)
Mozilla, Microsoft, and Google, whose browsers account for the lion's
share of those used, are revoking trust in all SSL certificates issued
by Malaysian intermediate certificate authority (CA) Digicert. The
decision was made because Digicert issued 22 certificates with weak
512-bit keys, missing certificate extensions, and missing revocation
information. Digicert received an intermediate CA certificate in July
2010; that certificate was issued by Texas-based Entrust. It should be
noted that Digicert, the Malaysian company, is not associated with
Utah-based CA DigiCert.

--BPI Asks BT to Block Pirate Bay
(November 4 & 7, 2011)
Following close on the heels of the movie industry's success in getting
BT to block users' access to Newzbin 2, the music industry trade group
BPI has sent a letter to BP asking it to block users' access to The
Pirate Bay. The letter asks BT to block The Pirate Bay voluntarily
within two weeks or face legal action. BT is likely to comply with the
request only if it is backed up with a court order. BT started blocking
Newzbin 2 to comply with a court order. BT was supposed to have begun
blocking access to the site by November 2; while the company said it had
the technology in place and planned to comply with the order, the site
was reportedly still available "over a standard BT DNS-based broadband
link."

--Cyber Atlantic 2011 Exercise Aimed at US/EU Collaboration
(November 3 & 4, 2011)
The Cyber Atlantic 2011 Exercise was conducted on November 3. The event
involved the EU and the US and helped both improve their international
cyber incident response capabilities and their collaborative efforts.
The exercise incorporated two attack scenarios. In the first, attackers
tried to steal and post secret data from EU members' cyber security
agencies. The second scenario involved the compromise of a supervisory
control and data acquisition (SCADA) system that controlled European
wind turbines. The exercise was orchestrated by the European Network and
Information Security Agency (ENISA).

--Microsoft Issues Workaround for Kernel Flaw Exploited by Duqu
(November 3 & 4, 2011)
Microsoft has issued a temporary workaround for a critical privilege
elevation vulnerability in the Win32k TrueType font-parsing engine that
is being exploited by the Duqu Trojan. The flaw affects all versions of
Windows from XP through Windows 7. Successful exploitation of the flaw
could allow attackers to "run arbitrary code in kernel mode." The
workaround involves disabling support for embedded TrueType fonts.
Microsoft plans to issue a patch for the flaw as soon as possible.

--Researchers Find Holes in Prison SCADA Systems
(November 7, 2011)
According to three researchers, some control systems used at federal
prisons are vulnerable to hijacking, potentially granting outsiders the
ability to gain remote control over industrial control systems and
programmable logic controllers allowing them to gain control of cell
door mechanisms and internal communications. The attack was demonstrated
at a conference in Miami late last month. The researchers provided their
findings to prison authorities at the state and federal levels and the
Department of Homeland Security (DHS) has confirmed those findings. The
researchers found that some systems that were not supposed to be
connected to the Internet in fact did have Internet connections, and
those that did not have Internet connections could become infected with
malware like Stuxnet brought in on a flash drive. Bill Brenner points
out that "this isn't a new threat," and ponders where the balance can
be struck between crying wolf and making sure problems are addressed.

[Editor's Note (Murray): Imagine what our security might look like if
we could harness the energy of these NVPs to work on solutions instead
of spending their time identifying obscure, but sensational,
vulnerabilities.]
--DoJ Withdraws Proposed Changes to FOIA Rules
(November 3 & 4, 2011)
The US Department of Justice has withdrawn a proposal to revise the
Freedom of Information Act (FOIA) rules that would have codified lying
to the public about the existence of certain documents. The DoJ's
proposed changes would have allowed the government to tell entities
requesting documents that the documents do not exist if the agencies
feel they should be withheld. The government already has the authority
to invoke the "Glomar response," which allows them to "neither confirm
nor deny" the existence of the requested documents.

[Editor's Note (Liston): All this time and energy wasted, and they
could've just gone and asked my mom. I remember having some rather
pointed conversations about similar topics when I was a child. DOJ:
Just so you know, my mom wouldn't really approve of the Glomar response
either...]
