Understanding the Kaseya Ransomware Supply Chain Attack

This month's attack on Kaseya, a widely used IT management platform, is a stark reminder of "supply chain" risk — attackers compromised software used by IT providers to manage their clients' systems, spreading ransomware downstream to potentially thousands of businesses through a tool that was supposed to help protect them.

For a small business, the direct lesson is less about this specific software and more about a broader principle: ask your IT provider how they secure the tools they use to manage your systems, including whether those tools require MFA and are kept patched as a priority.

If you were ever notified by your provider about exposure related to this incident, follow their remediation guidance directly — password resets, patching, or monitoring — rather than assuming no news is good news.
