WASHINGTON/LONDON/SAN FRANCISCO - Hackers working on behalf of China's Ministry of State Security breached the networks of Hewlett Packard Enterprise and IBM, then used the access to hack into their clients' computers, according to five sources familiar with the attacks.
The attacks were part of a Chinese campaign known as Cloudhopper, which the United States and Britain on Thursday (Dec 20) said infected technology service providers in order to steal secrets from their clients.
While cyber-security firms and government agencies have issued multiple warnings about the Cloudhopper threat since 2017, they have not disclosed the identities of technology companies whose networks were compromised.
IBM said it had no evidence that sensitive corporate data had been compromised. Hewlett Packard Enterprise (HPE) said it could not comment on the Cloudhopper campaign.
