AMSTERDAM — Russian hackers penetrated deep into the Dutch national police's digital system in 2017, during a period that Russian separatists were being investigated for the downing of a Malaysia Airlines flight that had departed from the Netherlands, Dutch daily De Volkskrant reports in an exclusive investigation.

The cyber attack, reportedly carried out by hackers belonging to the Russian security service SVR, was particularly troubling, De Volkskrant reports, because the police were working on the criminal investigation into the downing of flight MH17 from Amsterdam to Kuala Lumpur that was shot down on July 17, 2014 over eastern Ukraine.

Of the 283 passengers and 15 crew that were killed on July, 17 2014, when MH17 was shot down, 196 were Dutch. Multiple investigations have shown that MH17 was hit by a BUK missile, fired from a field in eastern Ukraine that was in the hands of pro-Russian separatists at the time. Russia has been blamed for consistently trying to undermine the enquiries.

The news of this new hack comes to light following the opening day of the Dutch MH17 criminal trial.
