US offers up to $10 million for information on alleged HAFNIUM hacker

The US is offering a reward of up to $10 million for information that could lead to Zhang Yu’s arrest.

He is accused of supervising people involved in cyberattacks and working with another accused hacker.

One campaign targeted Microsoft Exchange Server and reportedly compromised more than 12,700 US organizations.

The case matters because the attacks affected many organizations and included targets working on COVID-19 research.
