US offers $10 million reward for alleged Chinese hacker linked to Hafnium campaign

What happened and what to do

According to The Record, US authorities are offering $10 million for information on Zhang Yu, described as a prominent figure in the Hafnium campaign. According to those authorities, hackers in the campaign broke into thousands of computers and stole large volumes of documents.

For a company, the case shows that intrusions of this kind can reach many systems at once and go undetected for long periods. A practical response starts with an inventory of internet-exposed assets and software versions, with fixes prioritized by risk. Next, it is worth centralizing authentication and server logs, with alerts for unusual access and for large data transfers. A dashboard per system shows exposure status and outstanding fixes. For the risk of document theft, sensitive information should be classified, access restricted and outbound data monitored. None of this requires a new product; it requires collection, detection rules and tested response processes.

How the consultancy can help

Diagnosis of your organization's exposure to campaigns with a similar profile: inventory of exposed systems, review of software versions and pending fixes, and an assessment of log coverage. We then implement a collection and monitoring pipeline with exfiltration alerts and an exposure dashboard in your own environment, with agreed ongoing operation.
