The EU Agency for Cybersecurity (ENISA) has provided a statement with an assessment and advice on Microsoft Exchange vulnerabilities.
ENISA published a situation report which provides an assessment as well as advice and mitigation measures. It reports that threat has been assessed as severe and considers these types of attacks probable and of high risk.
The Agency calls on organisations using affected Microsoft Exchange versions to patch the flaws immediately and thoroughly investigate for potential signs of compromise.
At EU level, the EU CSIRTs Network and EU Cyber Crises Liaison Organisation Network (CyCLONe) are monitoring the situation and collecting information at both the technical and operational levels.
Microsoft is updating advisories and guidance while additional technical information and advice are provided by CERT-EU technical advisory.
