93% of attempted mobile transactions in 2019 were fraudulent

93 percent of total mobile transactions in 20 countries were blocked as fraudulent in 2019 according to a report on the state of malware and mobile ad fraud released by Upstream.

The number of malicious apps discovered in 2019 rose to 98,000, up from 63K in 2018. These 98,000 malicious apps had infected 43 million Android devices.

Android is the most vulnerable OS

With Android devices now accounting for an estimate 75-85% of all smartphone sales worldwide Android is by far the most dominant mobile OS. At the same time it is the most vulnerable due to its open nature, making it a favorite playground for fraudsters.

While it is always a good rule of thumb for consumers to only download mobile applications from Google’s official storefront, Google Play, thanks to its scale and set up, rogue apps are still getting through its defenses.

Of the top 100 most active malicious apps that were blocked in 2019, 32 percent are reported still available to download on Google Play. A further 19 percent of the worst-offending apps were previously on Google Play but have since been removed, while the remaining 49 percent are available through third-party app stores.

Fraudulent mobile transactions: Most targeted apps

Fraudsters appear to target some app categories more than others. Ironically, apps designed to make a device function better and make everyday life easier are the ones most likely to be harmful with 22.32 percent of malicious apps for 2019 falling under the Tools / Personalization / Productivity category globally.

The next most popular categories cybercriminals target are Games (18.97 percent) and Entertainment/Shopping (15.76 percent).

Indicating scale, in the course of only a few months in 2019, Secure-D reported on the suspicious background activity of five very popular Android apps: 4shared, a popular file-sharing app, Vidmate, a video downloader, Weather Forecast a preinstalled app on Alcatel devices, Snaptube, another video and audio app, and ai.type, an on-screen keyboard app.

With a total of nearly 700 million downloads, these were or had been at some point available on Google Play. In these five cases alone, 353 million suspicious mobile transactions were detected and blocked preventing $430 million in fraudulent charges.

“Mobile ad fraud is a criminal enterprise on a massive scale. Though it may seem that it is only targeted at advertisers, it greatly affects the whole mobile ecosystem. Most importantly it adversely impacts consumers; eating up their data allowance, bringing unwanted charges, messing with the performance of their device, and even targeting and collecting their personal data,” said Dimitris Maniatis, CEO of Upstream.

“It is more than an invisible threat, it is an epidemic, calling for increased mobile security that urgently needs to rise up in the industry’s priority list. Left unchecked, ad fraud will choke mobile advertising, erode trust in operators and lead to higher tariffs for users.”

The effects of mobile ad fraud are particularly damaging in emerging markets where data costs are significantly higher. As evidenced from detailed data presented from five such markets including Brazil and South Africa fraud rates in most cases exceed the 90% mark.

Consumers in emerging markets more vulnerable to digital fraud

As the report highlights consumers in emerging markets are more vulnerable to digital fraud; they are unaware of the dangers as they often go online for the first time via their mobile devices and data depletion caused by malware has a much greater effect on them due to the high cost of data in their countries.

In Africa 1 GB of data costs prepaid mobile subscribers the equivalent of 16 hours of work at minimum wage.

“A key part of successfully tackling mobile fraud is awareness”, explains Maniatis, “something that the whole industry, surprisingly, lacks. With all indicators pointing that its value will grow in the hundreds of billions in the next three years, we cannot afford to remain idle. This is the main reason we steadily and openly share all our findings with the whole community.”

“Mobile ad fraud remains a hidden threat for most consumers. It usually goes undetected and is not high on people’s agendas when choosing apps. However, aas the industry delays its response, consumers should take steps to stay safe from mobile ad fraud in 2020.”
