Cybersecurity and Infrastructure Security Agency orders federal agencies to rescan and recheck networks by Monday for any signs of compromise related to unpatched vulnerabilities in on-premises Microsoft Exchange servers. The agencies have until June 28 to implement CISA’s recommended steps to harden their infrastructure against attacks. CISA is directing additional actions to identify compromises that may remain undetected, the agency states. Microsoft patched the four vulnerabilities in the on-Premises version of Exchange Server on March 2; around 368,000 had been patched or mitigated.”]
