The U.S. Cybersecurity and Infrastructure Security Agency has added four security vulnerabilities exploited in attacks as zero-day to its list of bugs known to be abused in the wild.

According to a November 2021 binding operational directive, all Federal Civilian Executive Branch Agencies agencies are required to secure their systems against security bugs added to CISA’s catalog of Known Exploited Vulnerabilities.

CISA has now given U.S. federal agencies three weeks, until March 7th, to patch the four Apple and Microsoft security vulnerabilities and thwart attacks that could target their networks.

Even though the directive only applies to U.S. federal agencies, the cybersecurity agency strongly urges all organizations to fix the security bugs to block any attack attempts to compromise their Windows or iOS devices.

Since the BOD 22-01 directive was issued, CISA has included hundreds of new security vulnerabilities known to be exploited in the wild to its list of bugs, ordering federal agencies to patch their systems to prevent breaches.

Apple fixes actively exploited iOS zero-day on older iPhones, iPads.
