The government of Nunvaut’s communications system was the victim of a ransomware attack early Saturday morning, and as of Sunday night officials still did not know when systems would come back online.

“The [government of Nunavut] IT system was hacked early this morning, by a virus that targeted public services,” Premier Joe Savikataaq tweeted Saturday afternoon.

“I want to assure Nunavummiut that we are working non-stop to resolve this issue,” Savikataaq was quoted as saying in a media release Sunday evening. “I thank everyone for their patience and understanding.”

The release said “all government services requiring access to electronic information… are impacted,” with the exception of Qulliq Energy Corporation.
