Matt Bromiley, senior principal consultant with Mandiant, offers checklists for how small- and medium-sized businesses can identify and clear ProxyLogon Microsoft Exchange infections.

The Small-to-Medium Business Microsoft Exchange Checklist Is This Checklist for Me? The four vulnerabilities described in Microsoft's communications to date do not appear to affect Exchange Online or Office 365 services.

If you have a local, physical computer running Exchange, or someone may have deployed Exchange in the cloud-your organization may be at risk.

Although both are official Microsoft products, note that a cloud-hosted Exchange Server is different from Exchange Online, which is an entirely cloud-based solution.

This depends on how and where you have Exchange deployed - and is worth a conversation with your local or outsourced IT provider.

Create a 30-day plan: Contact a local IT security company or learn how to harden access to Exchange so we are better protected in the future.
