In response to the recent escalations in France and the Anonymous #OpCharlieHebdo cyber campaign against Islamic extremists platforms, hundreds of French websites have been defaced by Muslim hacktivist groups (mostly from North Africa, such as the Tunisian hacker group dubbed Fallaga).
The famous hacktivist group Middle East Cyber Army (MECA) created an #OpFranceFacebook event page for organizing cyber-attacks against French websites on January 15, 2015.Another famous hacktivist group Fallaga created a similar event page that organized an anti-France cyber-attack on January 10, 2015.
Additionally, the famous hacktivist group AnonGhost has made calls on several social media platforms to hack French websites. The group also uploaded a video to YouTube, in which they explain their motive to act against French websites: “In reaction of France’s crimes against Muslims in Mali, Syria, Center Africa & Iraq, bombing mosques, killing innocents, under the banner of ‘fighting terrorism.'”
Finally, motivation to hack French websites is high and the anti-France message is quickly spreading via social media platforms.
Security researchers have discovered ways to take control over roughly 70% of Android devices via a Web page or apps – mostly devices that have outdated versions. Although Google releases patches approximately every four months, most of the devices will likely remain vulnerable to attack because they will not be updated.
While the iOS operating system is only installed on Apple devices and it is relatively easy to obtain updates, security updates for Android OS devices are forced to pass through the mobile network operators and carriers – a hindrance that often takes a great deal of time.
The following chart describes the patching process for an Android device, from the first discovery of a vulnerability through to the repair that ultimately reaches the end-user device. The repair process at point C is typical for every software product. The repair software represented by point C is usually the end vulnerability window shown at point A.
Points D – G represent the repair process specific to Google; whenever a patch to Android becomes necessary, Google provides an update via its open source forum. The manufacturers produce the update, vendors release it and then the user installs the updated customized version of his operating system.
It should be noted that the patch release date is not the date when these updates are actually available to users. Once Google releases an update, the manufacturer must update it to suit his material. There is a possibility that the updates may never actually become available to the user, for example, if the vendor decides that distributing the update is too expensive for him.
As a result of the window of vulnerability and the different Google and the manufacturer release dates, hackers can use reverse engineering techniques to identify and exploit the vulnerability of a device by using the information found in the original published patch, or that of any other manufacturer who may have issued the patch at an earlier date.
Clearly, the fact that Google provides a secure platform for Android is insufficient – it is also important to ensure that their patches reach their targets, Android users, within the shortest possible time, to minimize the attack window.
