The crimes were directed at Patrick Siegbahn, who runs a site for small savers who early reviewed the pension company Allra's business.

In 2018, Patrick suddenly noticed that his mobile had no network.

It turned out that someone had managed to trick the operator's customer service into moving the number to a completely different SIM card - and with the help of this take over large parts of Patrick's digital life.

- The first thing the person did was to search for my correspondence with the prosecutor in the Allra case.

In the event of a second intrusion, the person gained control of the Whatsapp app and began asking questions to my contacts about the Allra trial, Patrick Siegbahn told SVT 2019.

Made a mistake

But the perpetrator had made a mistake.

Patrick discovered on his computer a series of brand new documents, from another person's account.

Patrick's conclusion was simple: the intruder simply chose to sync Patrick's computer with his own.

With the help of the material, the police investigation was directed at a 47-year-old man who had previously been convicted of, among other things, fraud.

The 47-year-old is now sentenced for his refusal for several cases of data breach, forgery of documents and several cases of illegal use of identity.

However, the district court does not consider that this is a serious data breach, partly because it is not entirely clear whether it was done to access Patrick's investigations into the Allra scandal.

Affected at least five others

The Economic Crimes Authority has stated in a letter that it has taken special security measures around its staff after the intrusion, which EBM considered should not only be seen as individual crimes against a private person but "put in a larger context of suspected crime of a completely different dignity and great social impact" .

Similar intrusions affected at least five other people, two of whom were called as prosecutors in the trial against the principals in Allra-härvan.

Through one of the witnesses' accounts, the intruder managed to gain control of four more email accounts.

However, these infringements have not been included in this case.

The investigation has found an agreement between Allra and a company that in practice is suspected to have been controlled by the 47-year-old, regarding "legal advice" for half a million kronor.

However, everyone's representatives have denied that they were involved in any data breach.
