Sophos<\/a> customers are protected from the exploitation of the new zero-day vulnerabilities affecting Microsoft Exchange.<\/p>\n

Identifying signs of compromise?<\/strong><\/p>\n

Anyone running on-premises Exchange Servers ( +\/- 2300 servers in Belgium) should patch them without delay, and search their networks for indicators of attack. The Sophos MTR team has published a step-by-step guide<\/a> on how to search your network for signs of compromise.<\/p>\n

What to do? <\/strong><\/p>\n

    \n
  1. Patch or disable<\/li>\n
  2. Determine possible exposure<\/li>\n
  3. Look for web shells or other suspicious .aspx files.<\/li>\n
  4. Query with Sophos EDR<\/li>\n
  5. Establish impact<\/li>\n<\/ol>\n

     <\/p>\n

    Protecting Sophos customers from HAFNIUM:<\/strong><\/p>\n

    Sophos Intercept X advanced, XG Firewall and other Sophos network and server security customers benefit from multiple protections<\/a> against the exploitation of the new vulnerabilities. More information on CERT.be (The Belgian Federal Cyber Emergency Team).<\/p>\n
