Take Care While Installing And Using HTML5 Apps on Your Device
HTML5 has been gaining popularity among app developers for some time. Developing apps in HTML5 over native mobile apps is advantageous in many ways. The first advantage is interoperability for all devices means the HTML5 app can work on all mobile platforms without any code change.
HTML is easy to understand and hence the app development process becomes much speedier than other coding languages. The maintenance of these apps is also easier. It is predicted that during the next year, HTML5 will be used for developing at least a half number of mobile apps.
Attract App Developers
Susceptible To Injection Attacks
HTML5 might attract app developers as well as business owners but while looking at the security side, it is not full-proof. It is found that the code written in HTML5 is susceptible to injection attacks. With these vulnerabilities present, a hacker can insert some malicious code into the device.
By this code, he can get the data stored on the device. More serious trouble starts when the infected app sends malicious code to other devices and spread the attack. Native apps are free from this danger at present and they are considered to be safer for mobile devices.
For running the HTML5 app, you require a middle layer which comprises of a web container. This container decodes the HTML5 and javascript code before executing on the mobile device. The problem arises when javascripts code calls the native or system functions such as camera. Hackers can put their code in this code segment and hack the system information. Middleware is the problematic part which is open for code injection attacks.
Web frameworks are generally prone to code injection attacks. It becomes more dangerous on mobile devices as there is no any browser software to filter or interpret the data coming from the device.
While installing the app user generally allows the app to access all system resources and this helps to spread the malicious code in other devices even through SMS or other information shared. It is found that a middleware known as PhoneGap can increase the chances of hacking attacks.
Right now the only way to protect your smart phones from code injection attacks is to take ultimate care while using HTML5 apps. Prevention is the only key and you can practice it with sanitization of the code, tainting the tags and restrict permission to access your device for untrusted codes.
Code sanitization refers to removing all unnecessary code and filter out the code and data. Tainting means checking if the tag belongs to any other source and tagging it for not running on the device. These things can certainly make your mobile device safe and less prone to hacking attacks.
