Stop SDK spoofing in your affiliate program
SDK spoofing lets dishonest affiliates simulate legitimate mobile install events without any real device or user, extracting CPI commission payouts from your program for conversions that never happened.

SDK spoofing extracts CPI payouts for installs that never existed
SDK spoofing is the most technically sophisticated form of mobile affiliate abuse. Bad actors reverse-engineer the SDKs used by mobile measurement partners, replicating the exact device-level signals, session identifiers, and event sequences that a legitimate install would generate. They then transmit these spoofed signals to your MMP without any real device, real install, or real user being involved. Your MMP records a valid install, your affiliate network attributes it to a publisher, and a CPI commission is paid out. No user ever downloaded your app.
SDK spoofing is particularly damaging for affiliate programs because it is nearly impossible to detect with standard MMP validation rules. The spoofed signals are exact replicas of legitimate install events at the data level. Detection requires analyzing behavioral patterns across the session lifecycle, comparing device signal clusters, and identifying statistical anomalies in install timing, location data, and post-install event sequences. Tapper's SDK spoofing detection combines MMP signal analysis with behavioral modeling to surface spoofed installs that pass all standard install filters.
How Tapper stops sdk spoofing on Affiliate
Three steps from connection to clean data, no engineering required.
01
Integrate with your MMP and affiliate network
Tapper connects to your MMP (AppsFlyer, Adjust, Kochava, Singular, or Branch) and your affiliate tracking, monitoring the full install signal chain for spoofing patterns.
02
Spoofed install signals detected through behavioral modeling
Tapper compares install signal clusters against known SDK spoofing signatures, analyzes statistical anomalies in timing and location data, and models post-install behavior to identify spoofed sessions that pass standard MMP rules.
03
Spoofed installs rejected before commission payout
Identified SDK-spoofed installs are flagged and excluded from commission calculations, protecting your CPI budget and providing the evidence needed to remove dishonest publishers from your program.

“Tapper played a key role in improving the efficiency of Du's performance marketing activity by addressing traffic quality issues within campaigns. Following implementation, Du achieved a 13% reduction in CPA and an 8.6% increase in order rate, demonstrating a clear improvement in conversion quality and overall campaign effectiveness.”

“We uncovered low-quality traffic that wasn't visible inside the platforms. Removing it delivered a 14% uplift in conversions and an 11.4% reduction in CPA, a meaningful efficiency gain for INFINITI's 2026 growth plans.”
David Barnes
Data & Technology Lead, Omnicom Group
40%
higher conversion rate
“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimizes against cleaner signals and the efficiency comes through quickly. For AMA Nissan, that was a 40% lift in conversion rate and a lower CPA on Google, with nothing else in the setup changing. That is the kind of result we want to offer clients as a matter of course.”

Frequently asked questions
Most fake install methods, device farms, emulators, bot scripts, require some form of real or simulated device. SDK spoofing bypasses devices entirely by directly transmitting the cryptographic signals your MMP expects from a legitimate install. There is no device to detect, no location to verify, and no session to analyze at the device level. Detection requires statistical and behavioral analysis of the signals themselves.
MMPs are aware of SDK spoofing and have built detection mechanisms, but sophisticated spoofing operations continuously update their techniques to bypass these rules. Because MMP detection relies primarily on device-signal validation, spoofing attacks that correctly replicate those signals can evade detection. Tapper adds a complementary detection layer focused on behavioral and statistical analysis that is harder to spoof.
Tapper provides a detailed evidence report for each flagged install, including signal cluster analysis, timing anomaly data, post-install behavior scores, and comparison against known SDK spoofing patterns. This documentation supports publisher removal from your program and can be submitted to your affiliate network as evidence for commission clawback requests.
