China has sought to exploit global cyber vulnerabilities to build its network of intelligence, trade secrets, and other data. As the latest revelations about a breach of Norwegian business software firm Visma make clear, the U.S. cannot push back on China’s nefarious hacking without cooperation from its allies.

On Wednesday, cyber-intelligence firm Recorded Future released a report on its investigation into an attack on Visma as well as two other unnamed companies: one a U.S. law firm and another a global apparel firm.
