UNUSUALLY AGGRESSIVE AND SOPHISTICATED CYBER ATTACKS HAS PENETRATED DEEP INTO USA INTERNET SERVICE PROVIDERS IN RECENT MONTHS TO SPY THEIR USERS:CISA INITIALLY SAID.

^{Chinese government-backed hackers have penetrated deep into U.S. internet service providers in recent months to spy on their users, according to people familiar with the ongoing American response and private security researchers.}

The unusually aggressive and sophisticated attacks include access to at least two major providers with millions of customers as well as to several smaller providers, people familiar with the separate campaigns said.

“It is business as usual now for China, but that is dramatically stepped up from where it used to be. It is an order of magnitude worse,” said Brandon Wales, who until earlier this month was executive director of the Cybersecurity and Infrastructure Security Agency, CISA.
