Basically, these are infectors targeting MS Networking. A FireWall and AV software is the
best protection. If you are on Broadband then using a Router such as the Linksys BEFSR41 is
a good way to mitigate the above threats from the Internet.
As always, I suggest blocking both TCP and UDP ports 135 ~ 139 and 445 on *any* SOHO Router.
It should also be noted that IPC$ is not alone. There are PRINT$, C$, D$, etc that are also
infection vectors so IPC$ should not be singled out. To help mitigate the attack on these
shares (some use dictionary attack methodologies), one must institute strong passwords to
user accounts and the Administrative accounts.
Suggested strong password method...
10 digit password minimum using.
2 - Upper case chars.
2 - Lower case chars.
2 - Numbers
2 - Special chars.
