Fake Fortnite apps target Android gamers
Popularity of the free-to-play shooter game Fortnite has been nothing less than a phenomenon. The number of Fortnite players as of June 2018 is recorded at a staggering 125 million. Fortnite is available on popular platforms – Windows, Mac, Playstation, Xbox and mobile devices. But when we say mobile devices, in this case, we mean Apple devices. Yes, Fortnite is currently not available for Android as shown on both Google Playstore and the official Epic website below:
However according to uploaders on Youtube, Fortnite can be installed on Android devices just fine:
SonicWall Threats Research Team observed a number of fake Fortnite apps that claim to be Fortnite for Android but end up fooling the victims into installing third party apps for the benefit of the scammers. We highlight few popular scams in circulation right now that use Fortnite as their cash cow:
Scam I: Get verified
This scam is probably the most popular one right now that involves Youtube. There have been a flurry of videos that claim to show instructions to install and run Fortnite on Android. The scam works as follows:
- Step I: Youtubers create videos showing how they can download, install and play Fortnite on Android devices. They add a link in their videos from where the fake Fortnite apps can be downloaded:
- Step II: After installing the app and running it the victim is greeted with logos, images and videos which are copied straight from the official game. This is very critical as it cements the victim’s belief that this app may actually be real:
- Step III: The victim is informed that some sort of mobile verification is needed before the game can be played:
- Step IV: On clicking “OK” a link opens where the victim is asked to install an app. The link and app changes based on the scam but a legitimately clean app (which is usually available on Google Play) is asked to be installed on the device. The victim installs this app with the belief that after this step he will be able to play Fortnite.
- Step V: When the victim returns back to the fake app, all he gets is an empty screen and is left wondering if he did something wrong. Most of the victims may try the previous step once more to try and “rectify” what they did wrong or they may try a different Youtube video thereby propagating the scam.
Scam II: App update
The initial step of this scam are similar to the one described above (Step I). The difference is what happens once the fake app runs on the device.
- Step II: Once the app runs it displays a screen stating that an update is needed, however shady terms are listed at the bottom where a user needs to scroll down.
- Step III: Both update and skip buttons move us forward and we begin seeing advertisements, also an update gets downloaded in the background:
- Step IV: Just like the previous scam, a legitimate app gets installed on the device:
In our case the fake Fortnite app installed Fortnite Battle Death but in reality it installed a legitimate game called Battle Death Combat:
But where is Fortnite ?? Anywhere but here…
Scam III: V-Bucks
V-Bucks are virtual in-game currency which can be used to purchase customization for a player character. These can be purchased online at legitimate places but in V-Bucks scammers saw an avenue for spreading their malicious schemes. The Playstore is littered with apps that promise free V-Bucks but are just another scam:
One such app entices the user to do something for the author/creator in exchange of V-Bucks, for instance follow a certain Twitch channel. But after doing so just displays a congratulatory message:
Another V-Bucks app has a little more depth. It requests for the Fortnite username of the user and puts up a show wherein fake V-Bucks are “calculated”:
The next screen asks the user to rate the current app and then claim the V-Bucks. When the user tries to claim the reward he is just transferred to either a survey scam or a website that tries to fish for emails or phone numbers. Either way this part of the scam is interested in the user’s data:
Although not malicious (as of now) these apps certainly trick users and seep sensitive data from them.
Scam IV – Droidjack
These are straight-up malicious apps that are disguised as Fortnite apps. They show no pretense whatsoever and contain malicious code that infects the device. Currently, we observed Droidjack infested apps – which has been covered earlier in our blogs.
We can expect other malicious apps to trojanize themselves as Fortnite in the near future.
Notable mention – Fortnite guides and tips
These are apps that contain few pages of tips and tricks for Fortnite, they may contain ads but are generally not malicious. Their sole purpose is to get installs from the users:
The main reason for using Fortnite is its popularity – Scammers and malware writers constantly target trending apps as their cover for spreading malicious apps. Another reason is that Fortnite is not available on Android at the moment but its available for Apple devices. This creates a void for Android users which leads some eager gamers to try alternative routes thereby committing the mistake of installing apps from untrustworthy sources.
What do they gain from these scams?
Different scams serve different purpose, here are a few insights:
- Verification related scams – These scams require the victims to install specific legitimate apps, when these apps are downloaded it gives the referrers (the scammers in this case) money. Its a win-win for both scammers and app developers
- The role of Youtubers – A lot of these scams are spreading via download links mentioned in YouTube video descriptions. App developers or companies offer Youtubers monetary benefits to promote their apps. A popular Youtuber can easily reach their audience with videos as YouTube is easily accessible these days
- V-Bucks scams – These apps usually demand the victims to rate the apps as one of the steps in earning V-Bucks. As a result these apps have been rated highly by a large number of users:
- DroidJack is one example where the app is completely malicious by nature without showing any pretense. We can expect more malicious apps that use Fortnite logo, name and images
Who are the likely targets?
- In case of the current Fortnite scams the prime targets are Android gamers as Fortnite is available on other platforms leaving Android gamers waiting for the official app. The long wait causes some people to take desperate measures and search for alternate ways to install Fortnite
- Some of the scams require the victims to perform a certain task – that may be install other apps, run a particular app for a specified time – in exchange of virtual currency. This needs sufficient time and the motivation to earn virtual currency – younger gamers fit this description in most cases. Mobile phones are very accessible these days and younger users may not have the money to buy virtual currency by themselves and they may not be too eager to research about these apps, the need for instant gratification takes over and they fall victim to such scams
