The state of Android security
Research from the AV-TEST Institute shows that Android malware samples collected have increased sizably every year. In 2014, the total was more than 326 million. The next year, the malware tally reached more than 470 million. In 2016, AV-TEST recorded nearly 597.5 million samples—nearly double the amount from two years earlier. And in 2018, we’re looking at 838.14 million.
By 2019, mobile malware will comprise about 33 percent of all malware reported in standard tests, up from 7.5 percent today, according to Gartner’s August 2017 “Market Guide for Mobile Threat Defense Solutions.” Though iOS devices aren’t immune from malware, “The mobile malware threat is primarily coming from Android,” said Dionisio Zumerle, research director at Gartner. The threat should be a concern for all companies with Android users, he said—especially those with large fleets of Android devices or that are in high-security verticals such as finance, healthcare, and government.
Android malware continues to become stealthier and more complex, too. For example, in October 2018, it was discovered that malware authors had been sneaking mobile banking Trojans into the Google Play store that masqueraded as device boosters and cleaners, battery managers, and horoscope apps. “These remotely controlled Trojans are capable of dynamically targeting any apps found on the victim’s device with tailor-made phishing forms,” according to the IT security firm ESET’s We Live Security blog. “Aside from this, they can intercept and redirect text messages to bypass SMS-based two-factor-authentication, intercept call logs, and download and install other apps on the compromised device.”
The good news? “Android security is improving, and the diversity of security applications available for the platform is strong,” said Nick FitzGerald, senior research fellow at ESET. “That means there’s more than one set of hurdles the bad guys must clear to have a highly successful malware campaign.”
