The U.S. Cybersecurity and Infrastructure Security Agency warned today of ongoing distributed denial-of-service attacks after U.S. organizations across multiple industry sectors were hit.

"CISA is aware of open-source reporting of targeted denial-of-service and distributed denial-of-service attacks against multiple organizations in multiple sectors," the cybersecurity agency said.

CISA, in collaboration with the FBI and MS-ISAC), provides guidance on what organizations should do before and after a DDoS attack, including enrolling in dedicated DDoS protection services which can reroute malicious traffic away from the targeted assets.

While the cybersecurity agency is yet to provide any context, today's warning comes after several DDoS attacks targeting both private and government organizations had their online portals taken offline in incidents claimed by Anonymous Sudan, a threat actor tracked as Storm-1359 by Microsoft that some cybersecurity researchers believe might be linked to Russia.

Earlier this month, Microsoft also confirmed that multiple outages impacting its Outlook, OneDrive, and Azure web portals resulted from DDoS attacks claimed at the time by Anonymous Sudan.
