Navy documents that reportedly appeared on the dark web have been deemed obsolete and would not affect operational matters, the navy said.

“After identification, the documents mentioned (in a news report) are obsolete and do not involve classified documents that could affect the navy's readiness and operations.

“Nevertheless, the navy will investigate the source of the leak,” it said in a statement today.

The navy reassured that it takes the matter seriously, and its information and communication technology systems remain in good order under the supervision of the armed force’s Cyber Defence Operations Centre.

Earlier today, Singapore’s Straits Times reported that documents originating from several armed forces and military contractors around the world have appeared on a dark web portal last month, including about 70 from the Malaysian navy.

The dark web is a portion of the Internet that is accessible using special browsers and protocols designed to mask the identity of its users, thus providing a high degree of anonymity.

The Straits Times reported that it is unclear whether the documents were intended to be sold or shared on the dark web, but it was supposedly gathered from several sources through the hacking of email accounts belonging to military personnel.

“Among them were documents pertaining to troop strength at several Malaysian navy and army bases during a holiday last year; senior and junior navy officers charged with corruption, drug consumption and being absent without leave; and naval exam requirements,” the report said.
