Even though the IMF spokesman rejected to comment on the extend of the attack, whether data breach happened to confidential information on the economic health of its 187 member countries or any systems were infiltrated, he said that they are "investigating" it.
"We had an incident," said IMF spokesman David Hawley. "We're investigating it and the fund is completely functional."
The Wall Street Journal reported that IMF staff received a routine notification about the incident by email Wednesday, Jun 8 asking them to contact their tech department if they saw anything suspicious.

The internet search engine Google also reported hacking attempt on Google mail accounts including senior US government officials, Chinese political activists etc. Google accused Chinese attackers behind the attack, that sparked another fight between Google and the Chinese Communist government.
Chinese government strongly rejected Google's accusation by saying that it was "unacceptable to blame China for all hacking attempts." Later, China's official newspaper People's Daily warned Google becoming a political tool of West and blamed that Google was "deliberately pandering to negative Western perceptions of China, and strongly hinting that the hacking attacks were the work of the Chinese government."
