Stop SDK spoofing in your affiliate programme
SDK spoofing lets fraudulent affiliates simulate legitimate mobile install events without any real device or user, extracting CPI commission payouts from your programme 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 fraud. Fraudulent 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 programmes because it is nearly impossible to detect with standard MMP fraud rules. The spoofed signals are exact replicas of legitimate install events at the data level. Detection requires analysing behavioural 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 behavioural modelling to surface spoofed installs that pass all standard fraud 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 behavioural modelling
Tapper compares install signal clusters against known SDK spoofing signatures, analyses statistical anomalies in timing and location data, and models post-install behaviour 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 fraudulent publishers from your programme.

“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.”
Joseph Elbcherrawy
Client Leadership Director, Mindshare, a WPP Media Brand
“During our Tapper trial for INFINITI, 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
“With Tapper's protection we were able to identify and block invalid clicks in real time. The impact was immediate as our cost per acquisition dropped by 30% and ROAS improved significantly. More importantly, Tapper gives us the confidence that our campaigns are reaching genuine customers, which makes it truly invaluable.”
Dimitris Bakas
Senior Performance Marketing, Public Group
“We started using Tapper to get better visibility on where our clicks were coming from, and ended up cutting wasted spend by over 12%. The performance uplift was clear, and for the first time, we could trust the numbers we were seeing. It's a total game-changer for campaign integrity.”
Stuart Parkin
Director of Operations, Regit
“Tapper's blocking technology purifies our paid media traffic which roughly equates to a 36x return against its subscription costs. It's certainly one of the easiest-to-implement tools in our entire marketing stack.”
Reno Mindemann
Head of Growth, Kama Capital
“We've been using Tapper for over a year now, and it has become a core part of how we run paid media. Invalid traffic was always something we knew existed but couldn't really act on. Tapper changed that. We're now saving up to $50K per year, and on PureSquare specifically, we saw around a 20% decrease in CPA. Based on these results, we decided to roll it out across other ventures under Disrupt as well.”

Frequently asked questions
Everything you need to know about stopping sdk spoofing on Affiliate.
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 analyse at the device level. Detection requires statistical and behavioural 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 behavioural and statistical analysis that is harder to spoof.
Tapper provides a detailed fraud report for each flagged install, including signal cluster analysis, timing anomaly data, post-install behaviour scores, and comparison against known SDK spoofing patterns. This documentation supports publisher removal from your programme and can be submitted to your affiliate network as evidence for commission clawback requests.
