The security issue related to OpenSSL has been all over the news in the last couple of days.
It is indeed a very bad issue, one that can let an attacker access the login details, including passwords, of registered users from vulnerable Websites/Servers. Yahoo mail, was one of those sites…out of nearly a million others!
This vulnerability has been around for 2 years, it affects servers usingOpenSSL 1.0.1 through 1.0.1f (inclusive).
Those servers could be running consumer websites or other applications. For example, the Network Security Monitoring suit: Security Onion, was vulnerable until yesterday when a security fix/update was released. The same applies to the Penetration Testing platform Kali 1.06, which was vulnerable until today!
If those applications/environments were internet facing, userids and passwords may have been compromised in the last 2 years.
This issue allows the attacker to access the memory of a vulnerable server, it means that ...

Bluetooth under attack

4 February 2014 - Author: SM - Category: Hacking
I have heard of Ubertooth for a while now and it seems it use to attack bluetooth devices keep growing. Once recent attack described HERE can leverage the Ubertooth sniffing capability to crack the encryption algorithm used by the Bluetooth Low Energy (BLE) standard. BLE is also referred to as Bluetooth Smart.
Sure, BLE/Bluetooth Smart is different from Bluetooth, but it issupported by most recent mobile devices (i.e.: the latest iPads and iPhone as well as some Android devices), and will be increasingly used in “smart” appliances, from toothbrushes to fridge if you believe this ...

Apple Security in the Enterprise

There is a good document from the UK government describing the different security features available in Apple Mac OS X 10.8 and the ones you should consider if using a Mac as an enterprise end point:
OS X 10.8 UK Gov security guidance document.
In light of all the noise created by the NSA and GCHQ surveillance programs you might be tempted to dismiss governments’ position and view when it comes to IT Security. However,I found that document quite good and high level enough to be understood by mid-level management at least :)
They do refer to an MDM solution for some of the controls without specifying which one, so I assume they are referring to a OS X Server Profile Management solution as described by Apple HER...

It seems I refresh the look of this website every 3 years and 3 years was up so here the new look :)
I decided to go with a slick, low maintenance theme.
It has also been a few months since I updated this website, hopefully this should change soon!

Using a phone as a keylogger, next it will be a smartwatch!

There is an interesting paper from Georgia Tech College describing a clever proof of concept where a phone is used to eavesdrop on keystrokes.
This is done by leveraging the phone motion sensor capability and placing it next to a keyboard. They managed to create a dictionary of words/vibrations that is able to recognise words typed on a keyboard just by analysing the vibrations made from typing.
Of course, you are likely to notice someone’s else phone sitting next to your keyboard but what if your phone got hacked and that software loaded onto it?
They conducted their proof of concept on an iPhone 4 but this is likely to be also possible on other platforms/devices.
In fact, with upcoming smart watches this concept will be even more relevant! Now I can see a use for that Apple M7 chip! ;)
As I am typing this note, my phone is next to my keyboard. Maybe I should move it awayR...

New iPhone 5S Fingerprint reader, a step in the right direction!

13 September 2013 - Author: SM - Category: Security
Apple has just announced two new models of iPhones, one of them is the iPhone 5S which comes with a fingerprint reader. Like others I believe this is no silver bullet, but it is a step in the right direction in terms of helping the masses to secure their iPhones.
There are two main areas of potential security failures:
– Fingerprints can be copied and once compromised you can’t “change” for new ones;
– The Fingerprint reader security implementation will be very important, any defects or flawed could be exploited to gain unauthorised access.
Apple may not be the first company to provide an embedded fingerprint reader into their phones, but like it did for tablets and smartphones, it will be the company that will popularise it...

Mobile Device Management Limitations

27 August 2013 - Author: SM - Category: Security
Current MDM frameworks, unless using some kind of container approach, will always play catch-up to hackers wanting to bypass the controls enforced to their phones, as highlighted in the following article describing how to get around Airwatch’s MDM restrictions.
The conclusion of that article is spot on:
“MDM solutions are great for employers to manage mobile devices. However, they are not without their problems. Not only was I able to bypass compliance for having a rooted device, but I was also able to bypass the need to encrypt my device from the profileGroupSetting table. Bypassing compliance restrictions for AirWatch is relatively trivial after a few hours and I’m sure it is probably similar with many others MDM solutions.”
An MDM container approach will only ensure your corporate data does not leave that secured container and stays safe wit...

The right (way) to disclose vulnerabilities
#86 - Posted on
24 August 2013 - Author: SM - Category: Security
An article was discussed last month in The Guardian and The BBCexplaining how a research paper from the University of Birmingham had been barred by a judge from being published because it discussed weaknesses in the security related to cars starting mechanisms from many manufacturers (BMW, Porsche, Fiat, Peugeot, etc).
This was already discussed publicly at the 21st Usenix Security Sympposium, where an online video is available. A quick search on Google also produces a PDF paper explaining how a car can be gone in 360 seconds through hijacking car key transponders. If that was the paper stopped from publication, then I don’t think it provided enough details that warranted those legal actions.
