Set out below are the AppsFlyer’s automatic anti-fraud protection solutions:

Fraud Issue

Issue Description

AppsFlyer’s Solution

Install Hijacking 

Fraudsters plant malware on mobile devices that alerts when a download of an app takes place. Instantly a click is sent to AppsFlyer claiming credit for the install.

AppsFlyer blocks attributed clicks with a very quick CTIT* (Click To Install Time).

Click Hijacking 

Malware identifies an install tracking link click and instantly sends another click that credits them if it is attributed.

AppsFlyer blocks attributed clicks occurring very fast* after other clicks for the same app on the same device.

Block Fraudulent Devices Using DeviceRank 

Fraudsters reuse the same mobile devices to commit fraud with different apps.

AppsFlyer’s unparalleled database of mobile devices is the biggest of its kind in the world encompassing over 98% of all smartphones on the planet.
This database allows us to rank all mobile devices globally according to their actions with all client apps. Thus suspicious devices are blocked from being attributed in real time.

IP Blacklists 

Fraudsters usually operate from click farms, which may be identified by their IP addresses for long periods of time.

AppsFlyer blacklists IP addresses suspected of fraud on a daily basis based on up to date data received from 3rd party global provider Digital Element.

SDK Authentication 

Fraudsters send fake SDK messages to simulate valuable user actions.

AppsFlyer uses a proprietary hashing protocol to encrypt internal messages between our SDKs and our web services, preventing fraudsters from mimicking the messages.

Store Validations 

Fraudsters send fake SDK messages to simulate installs or in app purchases so they can claim high CPA fees.

AppsFlyer enables install validation on iTunes and in-app purchase validation for both iTunes and Google Play, of any install or in-app purchase that has taken place to prevent attribution of fraudulent activities.

* AppsFlyer withholds the exact time values to protect our clients.
