SOFIA: Hackers stole thousands of Bulgarians' personal financial data and distributed it from a Russian-based email in an attack possibly related to the purchase of new F-16 fighter jets from the United States, the government said on July 16.
The hackers accessed the National Revenue Agency's (NRA) systems on July 15 before sending local media confidential information purportedly from Finance Ministry servers, Interior Minister Mladen Marinov said.
"Maybe this is the first case in Bulgaria which is successful and a lot of personal data has been stolen," Marinov told local bTV channel.
He said the cyberattack was probably motivated by Bulgaria's move to buy eight new Lockheed Martin F-16 fighters for US$1.256bil (RM5.16bil) from the United States, its biggest military purchase since the end of communism.
"A political analysis can also be made – the email comes from a Russian site ... and a crucial decision to buy the F-16s aircraft was made yesterday," Marinov said.
Once an obedient satellite of Russia, the Balkan nation has joined the European Union and trans-atlantic NATO alliance in the last decade, and is replacing its ageing Soviet made MiG-29 planes with the F-16s.
A leading Bulgarian newspaper, 24 Chasa, said one file emailed by the hackers had more than 1.1 million identification numbers with income, social security and healthcare figures.
According to local web site Mediapool, the email came from an address with Russian mail provider Yandex.
There was no immediate comment from authorities in Moscow.
Bulgarian media said the hackers' email included an appeal for the release of WikiLeaks founder Julian Assange. "Your government is mentally retarded. The state of your cybersecurity is a parody," reports quoted it as saying.
In a statement, the NRA said it and security agencies were checking "a potential weakness" in its computer systems. – Reuters
