Hackers Backed by Chinese Government Attack Global Cellular Networks

Hackers believed to be backed by China’s government have infiltrated the cellular networks of at least 10 global carriers, swiping users’ whereabouts, text-messaging records and call logs, according to a new report, amid growing scrutiny of Beijing’s cyberoffensives. The multiyear campaign, which is continuing, targeted 20 military officials, dissidents, spies and law enforcement — all believed to be tied to China — and spanned Asia, Europe, Africa and the Middle East, says Cybereason Inc., a Boston-based cybersecurity firm that first identified the attacks.
