Around 3,400 hackers from all over the world spent four weeks trying to get into Swiss Post’s future e-voting system. They put the system to the test by launching around 60,000 attacks. The intrusion test has now been completed. In this type of test, hackers attack an application and try to detect vulnerabilities. In the test, no-one succeeded in penetrating the e-voting system, or even the electronic ballot box. But Swiss Post still has not achieved its goals, even after completion of the intrusion test: further tests by ethical hackers and independent verification on behalf of the Swiss Confederation are currently being carried out.
