Review of recent high-profile cyber attacks underway.
Schumer noted that the New York City subway system was the victim of a computer hack in early June. This came on the heels of Colonial Pipeline having to shut down some operations, resulting in disrupted fuel supplies in the US Southeast, as a result of a cyber attack.
This week, JBS, a meatpacking company, paid a ransom equivalent of US$11 million (A$14 million) after its operations in North America and Australia were disrupted.
Schumer also said he is seeking a US$500 million increase in the US Cybersecurity and Infrastructure Security Agency's budget in response to such incidents.
He did not say what other legislation might be considered following a Senate review.
