Delay-based Internet geolocation techniques are repeatedly positioned as well suited for security-sensitive applications, e.g., location-based access control, and credit-card verification. We present new strategies enabling adversaries to accurately control the forged location. Evaluation showed that using the new strategies, adversaries could misrepre- sent their true locations by over 15000km, and in some cases within 100km of an intended geographic location. This work significantly improves the adversary's control in misrepre- senting its location, directly refuting the appropriateness of current techniques for security-sensitive applications. Wefinally discuss countermeasures to mitigate such strategies.
