A newly discovered flaw in the handling of TIFF image files effects machines running Windows Vista or Server 2008 as well as Office 2003 to 2010 and Microsoft Lync products on WinXP and Win7 with Windows 8 being the only one that does not contain this vulnerability.  According to The Register attack code is launched when the image is display with tricks the "OS into copying malicious code stashed in the file into memory and then hijacking the processor to execute it."

"The software giant said the flaw allows attackers to remotely execute code and install malware on a vulnerable system by sending an email or instant message or convincing a user to open a specially crafted webpage."

Everything you wanted to know about safe charging but were afraid to ask

The USB condom is an adapter which disables the two data ports present on your USB connector to prevent a malicious charger from installing interesting things on your smartphone, if you decide to stick it into a strange charger.  Many will immediately point out that this device is much larger than a simple power adapter which makes it easier to leave behind as well as being large enough to hide nasties of its own, so you wouldn't want to borrow someones condom.  If you read through the comments on Slashdot you can pick up some interesting problems that this device could cause, from devices which refuse to charge without their data connections active to devices which actively communicate the amount of power they will accept for a charge.  It is unlikely your device would have an expected amperage less than the USB spec and go up in flames but it is worth knowing that the possibility exists.

"Yep, a USB condom. That term is mostly a dose of marketing brilliance, which is to say that grabs your attention while also serving as an apt description of the product. A little company called int3.cc has developed a product—a USB condom—that blocks the data pins in your USB device while leaving the power pins free. Thus, any time you need to plug a device such as a smartphones into a USB port to charge it—let's say at a public charging kiosk or a coworker's computer--you don't have to worry about compromising any data or contracting some nasty malware. It's one of those simple solutions that seems so obvious once someone came up with it."

How to ruin your company in (Blackberry) 10 steps

Oh RIM, is this what happens when you change your name, celebrity spokesperson and infrastructure?  First you gave up on what we thought was an incredibly secure way to communicate and moved to the same ActiveSync environment of Android and iOS and then we find out that we were fooling ourselves and even the old BES encryption was broken.  Then we find out that our data plans might or might not work if we roam outside of our home carriers network, regardless of what travel plan we might have requested.  A patch Tuesday cycle could be the last straw for many; announcing two ancient Adobe vulnerabilities on the new BB10 OS which will need to be patched might assure some that you still have a passing acquaintance with security but for most it is just one too many flaws.  The Inquirer links to the BB security threads in this article.

"The Z10, Q10 and PlayBook all need patching for Adobe Flash vulnerabilities. If a user were led to a page containing crafted Flash content, an attacker could execute arbitrary code on an affected device. BSRT-2013-007 notes that an alternative attack would be to trick users into downloading an Adobe AIR application."

Microsoft Will Continue Windows XP Support, For a Price

Subject: General Tech | September 2, 2013 - 09:17 PM |
Tagged: windows xp, windows, security, microsoft, legacy, enterprise, custom support

Windows XP seems to be the OS that simply will not die, and it seems that Microsoft has given in slightly on its plans to no longer support the aging operating system. For those customers willing to pay, Microsoft will continue patching Windows XP through its Custom Support program.

Custom Support is mainly aimed at large enterprise and industrial customers who, for legacy or other reasons, have yet to move on to newer OS versions from XP. The program will pick up from where Microsoft ends its public extended support for Windows XP (Service Pack 3) on April 8, 2014.

Businesses that elect to go the Custom Support route and stick with XP will pay approximately $200 per PC for the first year alone. The systems in the program will continue to receive patches for vulnerabilities rated as “Critical” with optional patches for “Important” security issues available for additional fees, according to Gregg Keizer writing for PCWorld. Security issues classed by Microsoft as being of low or moderate importance will not be patched at all.

Microsoft will reportedly be delivering these patches through a secure channel other than the standard Windows Update in an attempt to keep non-paying Windows XP users from getting their hands on the patches.

For now, it seems that Windows XP is still here to stay in a big way, at least in the enterprise space where it is likely cheaper to keep XP in circulation than to upgrade PCs, retrain employees, and re-code legacy applications. It will cost a pretty penny to keep the old OS up to date and (mostly) secure, however.

Intel can now monitor every transaction on their network in real time

Subject: General Tech | August 22, 2013 - 09:17 AM |
Tagged: Intel, security

We have heard of another success in Intel's move into the security market from an 80 person team headed by Moty Fania which has created a device capable of real time scanning of everything that occurs on a corporate network.  It can handle four to six billion network events a day in its current state and the team claims a very high rate of true positives when scanning the internal Intel network for signs of breaches and industrial espionage attempts.  Sadly they did not disclose the hardware on which this tool is running to The Register but it is possible the custom software could be released by McAfee seeing as how Intel purchased them not too long ago.  With the current global climate they might have chosen a better response when asked the name of the software, the statement "it would not be "productive" to disclose its name" is perhaps not the most reassuring statement to make right now.

Worth trying out.

"Intel has created a Hadoop-based rig that analyses just about every network event in the company – four to six billion of them on business days - in close to real time so it can spot threats including industrial espionage."

Did you know your SIM card probably relies on 56bit DES?

Subject: General Tech | July 22, 2013 - 11:28 AM |
Tagged: SIM card, security, encryption, black hat 2013

The revelation that SIM cards rely on outdated encryption method make it surprising that an exploit has not been revealed long before now, but there is one that has been discovered and will be featured at this years Black Hat security conference.  The proof of concept used was to send an improperly signed binary SMS to a device over the air which returns an error that contains the entire cryptographic signature for the SIM that received the signal, from there it is rather simple to crack the 56bit DES with modern hardware.  Once you have the key you can send out a variety of commands to the device up to an including an OS update with certain customizations.  Follow the links from The Inquirer for more information.

The QR code vulnerability is patched but Google Glass still has security problems

Subject: General Tech | July 19, 2013 - 11:00 AM |
Tagged: google glass, security, wifi

The originally reported vulnerability was based around a specially designed QR code causing Google Glass to connect to a WiFi network not of the owners choosing which would allow monitoring of data flowing to and from the effected Google Glass device.  While this issue was indeed patched there you still need to be aware that connecting to random WiFi can be a big security risk thanks to an unpatched spoofing bug effecting essentially all browsers.  As The Register reminds everyone, unless you are at least encrypting your traffic or using a VPN your data transmission should not be considered secure.

"AUGMENTED REALITY EYEWEAR Google Glass is still vulnerable to attacks via connected WiFi networks allowing hackers to capture user data sent from the device, security firm Symantec has said, despite Google having quietly patched the eyewear last month."

Secure your dongle with Addonics

Subject: General Tech | July 8, 2013 - 11:09 AM |
Tagged: security, encryption, addonics, CipherUSB

The interface is pretty ugly but the Addonics CipherUSB is incredibly easy to use and is effective at folder level and disk level encryption.  With the dongle on your machine you can encrypt internal and external disks which can then only be accessed when a similarly set up dongle and a password if you selected the option to require one.  It uses AES256 ECB or CBC encryption, the standard when it comes to encryption and setup and usage are incredibly easy though there are a few minor flaws on the CipherUSB.  Head over to Techgage for the review and a great overview of encryption in general.

TG_Addonics-CipherUSB.jpg

"As important as data encryption can be for the home user, it’s even more imperative in the enterprise. The problem? The most effective measures are usually cast aside in lieu of something a little easier to deal with. With the CipherUSB, Addonics hopes to bring “simple” and “most effective” together as one. Does it succeed?"

Tag teaming malware, just what everyone needs

Subject: General Tech | July 3, 2013 - 10:16 AM |
Tagged: Vobfus, Beebone, Malware, security

Vobfus has been around the block a few times, some Visual Basic code that first popped up in 2009 which tried to download and install code to attack machines that managed to get Vobfus on their systems.  Beebone, aka Win32/Beebone is newer, a fairly common Trojan infection which is similar to Vobfus in that it attempts to download other malware as opposed to attacking your machine directly.  According to this story on The Inquirer, they have developed a symbiotic relationship, where when one infects you it immediately tries to infect you with the other.  That way it can fool anti-malware programs into beleiving that they've sanitized your machine of all infections when in fact you only remove one of the two infections and the remaining one immediately downloads and installs a different variant of the one you just removed.

"SOFTWARE HOUSE Microsoft's security researchers have discovered a pair of malware programs that help one another to avoid being detected by antivirus software.

Known as Vobfus and Beebone, the collaborating malware prove difficult to remove from infected machines as they work together, foiling the removal by regularly downloading updated versions of their respective partners."

Beware the click-jacking Captcha of Evil!

Subject: General Tech | July 2, 2013 - 10:29 AM |
Tagged: Malware, IE10, chrome, security

Just in case you weren't already getting tired of captchas there is a new click-jacking technique which works on both IE9 and 10 in Windows 7 and also on Chrome for Windows 8 so for the time being you might want to avoid any captchas that begin with an 'R'.  The new Smartscreen features on Win8 as well as UAC should give you at least some defense and require you to allow the exectuable to run and infect your machine but you can be guaranteed that some less observant users will click straight through without reading the messages which appear.  While this type of attack is nothing new, the particular technique mentioned at The Register does have some new tricks.

CAPTCHA.jpg

"A security researcher has discovered a sneaky social engineering trick that might be used to disguise the go-ahead to run hostile code on Windows 8 machines.

The so-called keyjacking technique, uncovered by Italian security researcher Rosario Valotta, is similar to clickjacking. However, instead of fooling marks into generating fake Facebook likes, the keyjacking involves disguising a "run executable" dialogue box within a CAPTCHA challenge."
