The Department of Homeland Security’s National Cybersecurity & Communications Integration Center (NCCIC) is warning users “to remain vigilant for malicious cyber activity seeking to exploit interest in Hurricane Florence.” Alongside these recommendations, the Multi-State Information Sharing & Analysis Center (MS-ISAC) released a cyber intel advisory on Sept. 14, which notes an uptick in internet activity related to Florence.

The Department of Homeland Security’s (DHS) rare public alert last week about a large-scale Russian cyber campaign targeting U.S. infrastructure raised a piercing alarm about vulnerabilities in the nation’s power grid, and underscored what officials have meant when talking about the need for a whole-of-government and whole-of-nation approach to cyber defense.
