SDK spoofing

Stop SDK spoofing on Google Ads

SDK spoofing generates fraudulent attribution events by replaying intercepted network traffic, stealing credit for installs that never happened and corrupting your Google UAC optimisation data.

SDK spoofing steals attribution without a real install ever occurring

SDK spoofing is among the most technically sophisticated forms of mobile ad fraud. Fraudsters intercept and analyse legitimate SDK traffic between your app and your MMP, then replay and manipulate those signals at scale to generate fake install and in-app event attributions. No real device is needed, no app is downloaded, and no user is ever acquired, yet your MMP records thousands of attributed installs that drain your Google UAC budget.

Because spoofed events are structurally identical to genuine ones, they pass the basic integrity checks built into most MMPs. The tell-tale signs are statistical rather than individual: impossibly high event frequencies from single devices, in-app event completions that precede the install timestamp, and post-install funnels that complete in seconds rather than the minutes genuine users take. Tapper's statistical anomaly engine surfaces these patterns across your install cohorts.

How Tapper stops sdk spoofing on Google

Three steps from connection to clean data, no engineering required.

Validate cryptographic event integrity signatures

Tapper verifies that install and in-app events carry valid cryptographic signatures from your MMP SDK, rejecting replayed or synthetically constructed postbacks that lack authentic signing.

Detect impossible event timing sequences

Events that complete faster than device hardware permits, or that arrive in sequences impossible within a genuine user session, are flagged as spoofed regardless of their apparent structural validity.

Protect UAC optimisation from corrupted signals

Spoofed installs and events are excluded from Google Ads conversion reporting, ensuring UAC optimises toward genuine user behavior rather than algorithmically generated attribution noise.

Tapper vs Google's Built-in Detection

See exactly where the gaps are, and why they matter to your bottom line.

Capability

Tapper

Google's Built-in Detection

Cryptographic event validation

Verifies MMP SDK signing on every install and in-app event postback received

Event timing anomaly detection

Flags events completing in sub-human time sequences across full install funnels

No temporal sequence analysis across the post-install funnel is performed

Cross-cohort statistical analysis

Compares install cohorts statistically to surface spoofing patterns at the network level

Individual install evaluation only; network-level spoofing patterns go unseen

MMP integration depth

Deep API integration with raw postback data access for full event inspection

No direct MMP integration; receives only aggregated conversion summaries

Success stories

Trusted by industry leaders

“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 Google Ads.

Device farms require actual physical or emulated devices to run apps and generate events. SDK spoofing requires no device at all. Fraudsters simply replay intercepted SDK network traffic to synthesise attribution signals. This makes SDK spoofing faster, cheaper, and more scalable for fraud operators, and harder to detect because no anomalous device behavior is ever generated.

In most cases, no. Tapper's SDK spoofing detection works primarily at the MMP integration and postback validation layer, which does not require a new app release. For advertisers who want the highest confidence level of cryptographic event signing, Tapper does offer a lightweight in-app component, but protection begins immediately through the MMP integration alone.

Yes. Tapper attributes fraud detections back to the originating network, sub-publisher, and placement where that data is available in your MMP. This means you can identify if SDK spoofing is concentrated on particular UAC inventory sources and feed that intelligence back into your campaign placement exclusions.
