An Asian cyberespionage group has spent the past year breaking into computer systems belonging to governments and critical infrastructure organizations in more than 37 countries, according to the cybersecurity firm Palo Alto Networks.

The state-aligned attackers have infiltrated networks of 70 organizations, including five national law enforcement and border control agencies, according to a new research report from the company. They have also breached three ministries of finance, one country’s parliament and a senior elected official in another, the report states. The Santa Clara, California-based firm declined to identify the hackers’ country of origin.

The spying operation was unusually vast and allowed the hackers to hoover up sensitive information in apparent coordination with geopolitical events, such as diplomatic missions, trade negotiations, political unrest and military actions, according to the report.
