The United Nations' computer network was hacked since April of this year, revealing a significant amount of data, Bloomberg News reported.
According to Bloomberg, UN spokeswoman Stefan Dujarric said on the 9th (local time) that unidentified hackers broke into parts of UN infrastructure in April.
The UN has detected and responded to additional hacking attempts since the hack in April, spokeswoman Dujarric explained.
As a result of the investigation, it was determined that the hackers were most likely accessing the UN computer network using the stolen IDs and passwords of the UN staff who were purchased from the dark web (a web that can only be accessed using a specific program).
It was found that they infiltrated the computer network and stole data that could target UN agencies.
The stolen IDs and passwords of UN employees appear to have been leaked from the UN's project management software, 'Umoja'.
According to cybersecurity firm ReSecurity, which uncovered hackers' intrusions into the United Nations' computer networks, the hackers entered the United Nations' deep internal networks through a raincoat.
It was revealed that they roamed the UN computer network from at least April 5 of this year to the 7th of last month.
Jin Yu, CEO of ReSecurity, said: "Institutions such as the United Nations are considered high-value targets when it comes to cyber espionage. It seems that this hack was planned for that purpose.”
