From the options below, choose the exploit against which this rule applies?

A.
IIS Unicode

B.
SQL Slammer

C.
MS Blaster

D.
WebDav

Explanation:
MS Blaster scans the Internet for computers that are vulnerable to its attack. Once found, it tries to enter the system through the port 135 to create a buffer overflow. TCP ports 139 and 445 may also provide attack vectors.
