Hackers Breach Berkshire Hathaway’s NetJets, Steal Client Data

NetJets Inc., a private jet company owned by billionaire investor Warren Buffett’s Berkshire Hathaway, is investigating a data breach after a hacker stole information about some of its clients, according to two people familiar with the incident and an email seen by Bloomberg News.

The attacker successfully “phished” an employee to steal their work account credentials and used that access to steal more information from NetJet’s systems sometime last month, according to one of the people, who asked not to be named because they were not authorized to talk about the breach.
