Enterprise phone provider 3CX has confirmed that North Korea-backed hackers were behind last month’s supply chain attack that appeared to target cryptocurrency companies.

3CX, which provides online voice, video conferencing and messaging services for businesses, worked with cybersecurity company Mandiant to investigate the attack. Hackers compromised the company’s desktop phone software used by hundreds of thousands of organizations to plant information-stealing malware inside their customers’ corporate networks.
