Hackers linked to the Chinese government have infiltrated Vatican computer networks, US cybersecurity firm Recorded Future reported.

It said the attacks began in May. The Vatican and Beijing were expected to engage in talks this year over the renewal of a landmark 2018 deal that stabilized relations between China and the Church.

US cybersecurity firm Recorded Future said in the report that the attacks targeted the Vatican and the Catholic diocese of Hong Kong, including the head of the Hong Kong Study Mission, who is seen as Pope Francis’ de facto representative to China.
