Russian spies likely tried to hack into the Dutch Safety Board's computer systems to access a sensitive final report into the shooting down of flight MH17 over Ukraine, experts said Friday.
The cyberattacks were revealed by security experts Trend Micro which blamed a shadowy group dubbed Operation Pawn Storm, "an active economic and political cyber-espionage operation" that has targeted the White House and NATO in the past.
A spokeswoman for the Dutch board, which led the investigation into how Malaysia Airlines flight came down in July 2014 over war-torn Ukraine, confirmed the board had detected the attacks.
But there was "no evidence" that anyone "was successful in the attempt," spokeswoman Sara Vernooij told AFP.
She declined however to reveal "how and by whom" the attacks were carried out.
Trend Micro Friday blamed Operation Pawn Storm for a "cyber-espionage operation before and after" the publication on October 13 of the board's detailed report.
