The good news is that mobile malware is still a very small portion of overall malware in the world. The bad news is that if it does grow in prevalence then it’s much more likely to hurt Android devices. Cisco’s annual security report claims that 99% of all mobile malware targeted Android devices last year, although the firm also notes that such malware only made up around 1.2% of all web malware encounters in all of 2013. That doesn’t mean that Android users should be entirely comfortable, however, because Cisco also says that “Android users, at 71%, have the highest encounter rates with all forms of web-delivered malware,” which Cisco says can include “phishing, likejacking, or other social engineering ruses, or forcible redirects to websites other than expected.” iPhone users, in contrast, accounted for just 14% of all web-delivered malware encounters.
