Learn how to defend against the most common attack on Android devices.
According to statistics gathered by Avast Threat Labs between October and December 2019, adware accounts for 72% of the attacks on Android devices, a dramatic increase over last year’s 34%. Mobile adware hijacks certain functions in the device in order to spam the user with unwanted ads. Aside from being annoying and ceaseless, the ads themselves can range from harmless to malicious. The most common method by which adware infects a device is through a malicious app. Attackers typically disguise the adware as gaming or entertainment apps, leaning towards whatever is currently trending.
There are two main types of adware - the spammers and the clickers. The spammers flood the device with unwanted ads. The clickers, also known as Ad-Fraud and Ad-Clickers, stealthily run operations on the device, such as clicking on ads, without the user knowing. It’s a way the attacker can harvest a large amount of ad click revenue.
“No one likes getting served with incessant ads,” commented Avast Head of Mobile Threat Intelligence & Security Nikolaos Chrysaidos. “They’re often unwanted and can ruin our enjoyment of an app. They could also pose a threat to users, as cybercriminals can use them as a backdoor to a device – whether it’s to make money from advertisers or steal your personal information.”
