Four recently-discovered vulnerabilities in Microsoft Exchange Servers - known collectively as ProxyLogon - grant attackers high privilege access to organizations' environments.

Discover the key facts, takeaways and vital next steps for you and your organization. F-Secure recommends all organizations patch these vulnerabilities as a priority and investigates those systems for evidence of compromise.

These vulnerabilities - and exploitation of them by threat actors - have dominated the cyber security news cycle for weeks. F-Secure has observed widespread exploitation by multiple threat actors to steal data and install malware to gain further access to organizations’ networks.

In this webcast F-Secure will cover:

  • The latest updates on the evolving threats
  • Insights into exploitation activity observed by F-Secure
  • How to identify potential breaches and exploitation on your systems
  • Key takeaways for you and your organization

Patching will not remove prior compromises, but it will prevent future exploitation. It’s vital organizations find out if they have already been breached.

This access can enable threat actors to:

  • Access email accounts and data stored on these systems
  • Install additional malware to facilitate long-term access to the compromised environment
  • Access credentials to enable further access to the wider environment

F-Secure has observed instances of access being used to steal data, install crypto-mining software and ransomware.
