smartphone blurA new study suggests that advertisements on websites pose the biggest threat for mobile users in catching malware on their smartphones.

Past pornography

Security company Blue Coat’s study reveals that mobile ads are now a bigger threat to phone security past pornography, which used to be the most common way for mobile users to encounter malware threats.

Networking firm Cisco says that even though mobile malware is increasing in number, it only accounts for 1% of all malware threats.

Stealth attacks

The study suggests this shift is due to the frequency people access the channels, but it does not rule out that pornographic sites are still effective vehicles for distributing malware.

“While users don’t access pornography that frequently, when they do, they are very vulnerable to malware,” according to the report.

Blue Coat noted that 12% of requested content and almost 20% of malware attacks are from adverts.

These ads were displayed via legitimate ad networks that contain hidden codes that direct users to malicious websites.

The report says that malware threats in web ads have tripled since 2012.
