The paper looked at around 2,100 reports of hacking from the first three months of 2013. So far only two of those cases have led to a court conviction.
The rest of them have either been dropped, or investigations are continuing, the paper reports, with over two-thirds of the cases being dropped within just a week.
One example is a case in Gothenburg where a company was subjected to a so-called DoS attack, which forced its homepage offline. Representatives of the company reported the incident and carried out their own incident report, which they then offered the police. However, the case was dropped by the police the following day, and they did not ask for the report.
