Microsoft OS Critical Security Problem in SMB

eWeek reports Symantec is seeing a large increase in port scanning on TCP/IP port 445, which is involved in a critical fix released by Microsoft last week. Stmantec believes hackers may be planning a major attack against the majority of Microsoft users -- who have not yet applied the out-of-monthly-cycle patches.

It is probably a wise idea to lock down your machine with the Microsoft patches.
