Why SDK spoofing costs advertisers so much
The damage goes beyond wasted clicks. SDK spoofing corrupts your bidding data, distorts your audiences, and erodes the performance of every campaign it touches.
SDK spoofing is an advanced form of invalid mobile traffic where attackers intercept legitimate app traffic and use it to fabricate fake install and post-install event signals. By reverse-engineering the SDK communication between a real app and its attribution platform, bad actors generate realistic-looking attribution data for installs that never actually happened - without needing to download the app at all.
SDK spoofing is particularly dangerous because it produces attribution signals that are indistinguishable from legitimate installs at the MMP level. Standard mobile detection tools that rely on device fingerprinting or IP blacklisting cannot catch spoofed SDK signals because no real device is ever involved. Advertisers continue paying for installs and in-app events that were never real, often for months before the spoofing is detected.

How Tapper detects and blocks SDK spoofing
Real-time detection and blocking across all your ad platforms, with no engineering required.
01
Tapper validates the cryptographic integrity of SDK attribution signals, identifying requests that have been fabricated or replayed rather than generated by a real device during a genuine install.
02
Even without direct SDK access, Tapper cross-references attribution signals against real device activity patterns to detect spoofed installs that carry inconsistent behavioral fingerprints.
03
Identified spoofed installs and in-app events are rejected before any cost-per-install or cost-per-event payout is triggered, keeping your attribution and budget clean.

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.”

“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.”
