// Malicious App Code
func exploitLogicIssue() {
    let sensitiveData = accessSensitiveData()
    sendDataToAttacker(sensitiveData)
}

func accessSensitiveData() -> [String: Any] {
    // Exploit logic issue to gather sensitive data
}

func sendDataToAttacker(_ data: [String: Any]) {
    // Send sensitive data to a malicious actor
}
