Summary

A recent campaign utilising SQL Slammer Worm has been discovered, this malware had been dormant for over a decade.

Threat details

SQL Slammer Worm was identified as attacking Microsoft SQL Server 2000 or Microsoft SQL Server Data Engine 2000, which haven’t been patched for 14 years. The Worm infects the server via UDP (User Datagram Protocol) port 1434 and attempts a DDoS attack of the server.


Remediation steps

Type Step
  • Ensure that the most recent patches have been applied to the SQL Servers, however the target severs are no longer supported by Microsoft therefore consider updating to a newer version.
  • Monitor for suspicious activity on UDP port 1434.
