Eleven suspected members of the Turkish far-left guerrilla group DHKP-C were on Friday charged with membership of a terrorist organization and weapons charges after a joint operation by the Hellenic Police's counterterrorism unit and the National Intelligence Service led to the discovery of a tunnel containing heavy artillery in Sepolia, near central Athens.
The Prime Minister's office, the Ministry of Foreign Affairs, the National Intelligence Service (EYP) and the Hellenic Police (ELAS) were the targets of an international cyber espionage campaign in April 2019 code-named "Sea Turtle."
According to verified sources, the unknown perpetrators were able to gain access to the internal networks of government agencies.
Last week's attacks by Turkish hackers on websites of Greek state bodies including the Greek Foreign and Finance ministries, the National Intelligence Service (EYP) and Parliament are the latest in a string of such incidents over the years which, however, have not led to any data being stolen, according to sources.
