As the world moves towards web browsing with a mobile device, protecting both your mobile device and your PC becomes increasingly important. While this may not seem like a big deal at the moment, thanks to the security of today’s smartphones, the same thinking applied to personal computers in the 1980s and 1990s. Over time, hackers and malware authors have turned their attention to mobile phones as the fastest growing way to connect to the Internet (to date). Like companies, hackers and malware writers go where people go. And the smartphone user world is the human world!
In short, yes! Smartphone malware (yes, even for the iPhone) has floated on the Internet for a long time, spreading across mass networks that are so inextricably linked. Hackers use tools such as Whatsapp (with more than a billion active users per month) to spread viruses with astonishing success. By the end of 2014, there was a very large case of malware spreading due to a demonstration in Hong Kong. The creator of the malware reached several thousand people in Hong Kong through Whatsapp with the news that he had created an application to host the event. Of course, many people took the bait. The application was actually a Trojan horse disguised as a demonstration tool, but in reality it was only used as a malicious program.
Another large-scale attack on iOS was WireLurker, a very smart malware that the user could not know about was installed. The WireLurker affected far more iPhone users than the Hong Kong Trojan protester, some estimates put the number of affected devices at around 350,000. WireLurker first infected the Mac, then spread out using more traditional methods such as hidden downloading or bundling (where you get exactly what you expect, plus other software, sometimes malware) and then waited until the iPhone was connected to the Mac to infect it while you were there. The infected devices would then be vulnerable to data theft if the infected device was hacked in prison (a very common way in the iOS community to remove the restrictions Apple places on the iPhone by allowing you to download and install custom apps with Apple certification; often used to get paid apps for free), the danger was compounded. Without Apple certification, WireLurker can download anything to your iPhone.
The most common attack on smartphones was the Cyber.Police and ICE malware, a form of mobile ransom aimed at more than 1.5 billion Android devices worldwide. The malicious program blocks the smartphone screen and displays pornographic images, indicating that you have 3 days to pay the ransom. You can’t unlock your screen without resetting your default settings.
All this can be solved using both mobile and PC protection.
