Sound scary? You can blame a new technology that is behind the development of your favourite apps.
An emerging technology called HTML5-based app development has been rapidly gaining popularity in the mobile industry.
"When the adoption of this technology reaches certain threshold, worm attacks would become quite common unless we do something to stop it," a latest report from US-based IT research agency Gartner warned.
By 2016, 50 percent of the mobile apps will be using HTML5-based technologies.
A notorious problem of the HTML5-based technology is that malicious code can be easily injected into the programme and get executed.
That is why the Cross-Site Scripting (XSS) attack is still one of the most common attacks in the Web.
"XSS attacks can only target at web applications through a single channel (Internet) but with the adoption of the same technology in mobile devices, we have found out that a similar type of attack can not only be launched against mobile apps," Gartner noted.
It can attack from Wi-Fi scanning, Bluetooth pairing, MP3 songs, MP4 videos, SMS messages, NFC tags and contact list.
"As long as an HTML5-based app displays information obtained from outside or from another app, it may be a potential victim," Gartned added.
