The founder of the Pirate Bay torrent site has been sentenced to three and half years in jail in “the largest hacking case to date.” Swede, Gottfrid Svartholm Warg, and his Danish accomplice were accused of hacking and accessing confidential information.

Warg, alias Anakata, and his 21-year old Danish accomplice, aka JLT, appeared in the Court of Frederiksberg in Copenhagen on Thursday morning.

The two were found guilty of “systematic and comprehensive” hacking of computer mainframes operated by US IT giant CSC between February and August of 2012. The prosecution indicted Anakata and JLT of downloading social security numbers from Denmark’s national driving license database, illegally accessing information in a Schengen Region database and cracking police email accounts.

“This is the largest hacking case to date. The crime is very serious, and this must be reflected in the sentence,” Prosecutor Maria Cingali said.

JLT, who has already served 17 months of pre-trial detention, was released.

His lawyer Michael Juul Eriksen dismissed Cingari’s calls for a two-year sentence for his client as "completely crazy,” the Local reports.

Warg’s sentence was delivered on Friday, the day after he was found guilty. The prosecution was calling for the maximum possible term of six years in prison. In addition, Cingali called on the court to ban Warg from re-entering Denmark, calling the Pirate Bay founder “a threat to the interests of Danish society.”

Both Warg and his defense have been insisting that Anakata was not the only one who had access to the MacBook computer that was used for hacking. Warg stressed the computer did not belong solely to him, but to the group of developers, meaning that the computer’s security could be comprised and any of them could actually intrude into the system operated by CSC.

“My recommendation has always been that the investigation has focused on finding clues that point to my client, even though the tracks have also pointed in another direction,” lawyer Louise Høj said, as cited by TorrentFreak.com. “It is clear that my client’s computer has been the subject of remote control, and therefore he is not responsible.”

However, the prosecution managed to present the evidence – a discussion on security and setup of CSC’s databases and systems which took place between hackers with the names “Advanced Persistent Terrorist Threat” and “My Evil Twin”. Under those pseudonyms lurked Gottfrid and his IT consultant co-defendant, the prosecution said, according to the TorrentFreak website.

All three judges and four of six jurors supported the guilty verdicts.

Judge Kari Sørensen said that remote control access to Warg’s computer was “unlikely,” given that the defendant was reluctant to reveal details about the identity of the persons, who he suspected could remotely control his computers.

Judge Ulla Otken also dismissed the remote control claims saying that Warg is guilty because the access was “systematic.” Two jurors agreed that Warg’s argument cannot be ruled out.

Warg’s lawyer has been calling for a one-year sentence for his client.

Warg’s mother has told the Local that the prosecution’s evidence is “vague,” saying that “a dirty approach to smear” her son as a person was used.

Warg has so far spent 11 months in prison in Denmark following his extradition from Sweden in November 2013.

Prior to that Warg was deported to Sweden from Cambodia in September 2012, following his arrest in the Cambodian capital Phnom Penh over copyright violations in 2009.

In Sweden, the Pirate Bay founder was charged with hacking the IBM mainframe of Logica, a Swedish IT firm that provided tax services to the Swedish government, and the IBM mainframe of the Swedish Nordea bank in order to transfer money to accounts held by four young men in Malmö.

However, in September 2013, the Swedish court of appeals cleared Warg of Nordea bank hacking after the defense claimed that the hacker’s computer could have been controlled remotely.

The court upheld a conviction for hacking into IT firm, Logica.
