Radar / FanDuel WV: tampered iOS app placed bets from Tennessee

RadarFanDuel

What we tested. Re-signed iOS FanDuel app, modified to bypass security controls. Tester located in Tennessee, targeting the FanDuel WV platform.

What happened. The modified build successfully placed bets from out-of-state. Radar failed to detect the modification.

Cross-reference. Contradicts the Apr 7 result at Bet Saracen AR, where Radar DID detect a re-signed iOS app with appropriate error messaging. Re-signed iOS detection is inconsistent across operators — fix one, the other still fails.

Why it matters. App-resigning is a well-known attack class. A regulator audit that includes a tampered-app test will not accept an inconsistent result.
