Nao_Sec, an independent cybersecurity research group, recently informed the public of a new Microsoft security vulnerability: Follina.

What do you need to know regarding Follina?

  • This vulnerability can be triggered through something as simple as opening a malicious Word doc in preview mode in Microsoft Outlook
  • There is currently no patch available for this zero-day attack
  • Do NOT open any attachments if you do not know the sender or you are not expecting the attachment (If you are unsure, call the sender to verify the email and attachment are legitimate)
  • Named “Follina” after reference “0438” in malicious sample, the area code of municipality in Treviso, Italy, called Follina
