The Cybersecurity and Infrastructure Security Agency (CISA) has issued an emergency directive asking federal agencies to take immediate action to identify and mitigate system vulnerabilities to protect their devices from a major hacking campaign, the agency said in a Sept. 25 statement.

“This widespread campaign poses a significant risk to victims’ networks by exploiting zero-day vulnerabilities that persist through reboots and system upgrades,” CISA said.
