1. Understanding Mobile Ad Fraud Methodology
Mobile ad fraud employs diverse and malicious techniques, adapting based on several factors. These parameters influence the type of fraud, its scale, and the target that fraudsters aim to exploit. Understanding these methodologies is vital for robust fraud prevention strategies.
Key Factors Influencing Mobile Ad Fraud:
- Fraudster target and goal
- Exploited weaknesses or loopholes
- Available technology
- Level of sophistication
- Financial capabilities
These elements collectively dictate the fraud type, scale, and the specific target a fraudster intends to exploit. Recognizing these aspects is essential for developing effective countermeasures.
1.1. Categories of Mobile Ad Fraud
Mobile ad fraud is broadly categorized into two main types: attribution hijacking and fake installs. Understanding these categories is the first step in combating mobile ad fraud effectively.
- Attribution Hijacking: Fraudsters manipulate attribution conversion flows using fake click reports to steal credit for installs from other media sources.
- Fake Installs: The entire user journey is fabricated, including impressions, clicks, installs, in-app events, and users, rendering user acquisition data worthless.
| Real Users | Fake Users | |
|---|---|---|
| Engagement | Real | N/A |
| Activity | Attribution Hijacking | Fake Installs |
Attribution hijacking involves real users but distorts marketing budget allocation. Fake installs, on the other hand, offer no value to advertisers, making data unreliable. Accurate fraud detection is crucial. For more insights, visit CONDUCT.EDU.VN.

2. Attribution Hijacking Methods
Attribution hijacking is a prevalent fraud tactic that relies on manipulating real user interactions to steal credit for app installs. This section delves into specific methods, their detection, and implications for advertisers.
2.1. Install Hijacking
Install hijacking occurs when fraudsters steal credit for an install generated by a legitimate media source. Techniques include sending false click reports or injecting false referrer data.
How Install Hijacking Works:
- A user clicks on an ad from a legitimate media partner.
- The user is directed to the app store to download the app.
- The Android device broadcasts that a new app is being downloaded.
- Malware on the device generates a fake click report, making it appear as though the fraudster generated the install.
- Attribution is stolen upon app launch.
This method exploits the basic attribution model, but is relatively easy to identify using CTIT (Click-to-Install Time) measurements and anomaly detection.

2.2. Click Flooding
Click flooding involves fraudsters sending a high volume of false click reports from or on behalf of real devices. The goal is to falsely credit the sub-publisher with the install when the actual device downloads the app.
Process of Click Flooding:
- Fraudsters create publisher accounts across various attribution channels.
- They gather attribution URLs for as many apps as possible.
- Clicks are populated with real device details via malware or purchased user data.
- Clicks are generated randomly or based on user activity.
- When a user organically downloads an app, a false click is associated with them.
- The fraudster is credited with an organic install when the app is launched.
Click flooding can be identified and blocked using low conversion rates and CTIT measurements. A long CTIT rate indicates attempted click flooding. CONDUCT.EDU.VN offers resources to enhance fraud detection.

3. Key Takeaways on Attribution Hijacking
Attribution hijacking, while seemingly simple, carries significant implications for advertisers. Understanding its complexity, potential gains, and business effects is crucial.
3.1. Complexity of Attribution Hijacking
Attribution hijacking methods are relatively simple to initiate and operate, requiring basic technology. The reliance on real user data means that much of the data is generated organically rather than falsely inserted into postback information.
3.2. Potential Gain from Attribution Hijacking
The potential gain is considered limited due to its simplicity, making it easy to detect with standard CTIT measurements. Operations are limited by the finite number of real devices to exploit.
3.3. Business Implications of Attribution Hijacking
Advertisers receive some value from real users, but marketing budget allocation is manipulated. Legitimate publishers are not rewarded, affecting future budget decisions.
4. Fake Installs Fraud Methods
Fake installs involve creating entirely fictitious user journeys, presenting a different set of challenges and implications for advertisers.
4.1. Device Farms
Device farms are locations packed with actual mobile devices clicking on ads and downloading apps, hiding behind false IP addresses and device IDs.
Characteristics of Device Farms:
- Located in remote areas or any space that can hold a large number of devices.
- Operated by low-paid employees or emulators.
- Constant app engagement and device resetting.
- Generate revenue by creating engagement and resetting device identities.
Monitoring a campaign’s New Device Rate (NDR) for anomalies can indicate device farm activity. According to AppsFlyer’s data, common NDRs should not exceed 10%-20% of a campaign’s activity. For more information on identifying device farms, visit CONDUCT.EDU.VN.

4.2. Bots
Bots are malicious codes that run a set program or action, sending clicks, installs, and in-app events for installs that never occurred.
Capabilities of Bots:
- Automate any action within the user flow or the app itself.
- Mimic real user behavior based on behavioral biometrics data.
- Trained to appear as engaged “real” users.
- Offer services such as harvesting game resources, passing levels, and generating revenue for third parties (Fraud as a Service or FAAS).
Fraudsters adapt to advanced detection logic and train bots to bypass in-app engagement measurement points.

5. Key Takeaways on Fake Installs
Fake installs present different challenges compared to attribution hijacking. Understanding their complexity, potential gains, and business implications is crucial for combating them.
5.1. Complexity of Fake Installs
Fake install methods are more complicated to operate and maintain, requiring a high level of technological skill to generate users and randomize behavior at scale.
5.2. Potential Gain from Fake Installs
Once successful, fake user fraud schemes present unlimited potential scale, as they do not rely on real users or devices. This makes operations potentially limitless and profits much higher.
5.3. Business Implications of Fake Installs
Advertisers receive zero value from fake installs. User interactions are pre-programmed to drain CPA rates, and the advertiser’s data becomes worthless due to the mixture of fake and real users.

6. Specific Fraud Techniques
Beyond the broad categories, specific techniques such as SDK hacking and in-app fraud present unique challenges and require specialized detection methods.
6.1. SDK Hacking
SDK hacking involves fraudsters feeding false information into advertiser servers by adding code to an app (the attacker) that generates simulated ad clicks, installs, and engagement signals on behalf of another app (the victim).
How SDK Hacking Works:
- Fraudsters add code to an attacking app.
- The code generates simulated ad clicks, installs, and engagement signals.
- The signals are sent to the advertiser’s attribution provider on behalf of a victim app.
- The advertiser pays for installs that did not occur.
SDK hacking is common with attribution providers that have weaker SDKs or poor security infrastructure. A closed-source, encrypted SDK provides better protection. CONDUCT.EDU.VN offers resources to safeguard against SDK hacking.
6.2. In-App (CPA) Fraud
In-app CPA (Cost Per Action) fraud involves fraudsters targeting key in-app events to generate revenue, exploiting the CPA model designed to reward actions beyond installation.
Common In-App Events Targeted:
- Level reached
- Tutorial completed
- In-app purchase made
Fraudsters use sophisticated bots specifically designed to bypass install fraud detection and trigger rewarded in-app events, crushing advertiser in-app economies.
6.3. In-App Purchase Fraud
In-app purchase fraud targets in-app marketplaces, where fraudsters attempt to generate revenue by simulating purchases of merchandise, services, or virtual goods.
Characteristics of In-App Purchase Fraud:
- Targets apps with freemium business models.
- Fraudsters aim for CPS (Cost Per Sale) rates, which are the highest in the market.
- Fraudulent in-app purchase attempts are increasing across major verticals.
Advertisers need robust fraud detection to protect revenue streams generated by legitimate transactions.
7. Understanding False Positives
A false positive occurs when a legitimate install is incorrectly flagged as fraud. Managing false positives is critical to maintaining trust and accuracy in fraud detection systems.
7.1. False Positive Test
The false positive test sets the allowed precision level for fraud detection algorithms. A higher precision level means a lower false positive rate.
Impact of False Positives:
- Penalize legitimate sources.
- Harm the advertiser’s relationship with quality media partners.
- Compromise the integrity and credibility of the fraud solution.
Responsible fraud solutions minimize false positive rates to protect client interests and maintain the credibility of media partnerships.
