Brussels, Dec. 19 (PTI/AFP): The EU announced an urgent investigation on Wednesday after hackers with possible links to China accessed thousands of sensitive diplomatic cables.
In the latest embarrassing data breach to hit a major international organisation, the New York Times reported that hackers using similar techniques to the Chinese military gained entry to EU communications.
The cables from European Union diplomatic missions around the world reveal anxiety about how to handle US President Donald Trump as well as concerns about the behaviour of China, Russia and Iran.
The leak, discovered by cybersecurity firm Area 1, recalls the publication by Wikileaks of a vast haul of US State Department cables in 2010, though in the EU case the trove is much smaller and consists of less secret communications, the NYT reported.
EU officials said they have begun a probe into the leak, which comes with Europe on high alert for malign online activity in the run-up to key parliamentary elections in May next year.
"The Council Secretariat is aware of allegations regarding a potential leak of sensitive information and is actively investigating the issue," the EU Council, which represents member states, said.
"The Council Secretariat does not comment on allegations nor on matters relating to operational security. The Council Secretariat takes the security of its facilities, including its IT systems, extremely seriously."
European Commission Vice President Valdis Dombrovskis said the bloc took any report of hacking its systems "extremely seriously" but refused to comment on the detail of the leak.
"What is clear is that no institution or country is immune to these kinds of hacks - all communications systems have vulnerabilities," he told reporters.
"We're constantly dealing with this challenge, upgrading our communication systems to respond to the threats." In one cable, the EU's diplomatic mission in Moscow describes the controversial summit in Helsinki in July between Trump and Russian President Vladimir Putin as "successful (at least for Putin)".
Another gives a detailed account of a meeting with Chinese President Xi Jinping in which he rails against Trump's trade tactics, saying the US was "behaving as if it was fighting in a no-rules freestyle boxing match" and vowing not to give in to "bullying".
There are extensive reports on the situation in Ukraine, where a conflict rumbles on between government forces and pro-Russian separatists, including a warning dating from February that Moscow may already have deployed nuclear warheads in Crimea, which it annexed in 2014.
The NYT said that, according to Area 1, the techniques used by the hackers over the course of three years were similar to those used by an elite Chinese military unit.
The hackers apparently gained access to the diplomatic communications network after a simple "phishing" campaign targeting EU officials in Cyprus with mails designed to trick them into downloading hacking tools.
Many of the cables are run-of-the-mill weekly reports from missions around the world, detailing conversations with leaders and officials, the NYT said.
More sensitive, classified communications are handled on a different, more secure system.
