back to article DDoS attacks fall as crackers turn to spam

Is it really that difficult?

I've been thinking about a way to curb spam once and for all, surely it could be this easy:

Residential ISP's should simply block clients from connecting to any address on port 25, except their own SMTP server.

Instantly stopping any botnet from being able to send out.

Guys?

Not quite, Phil

It wouldn't be hard at all to write a webscraper that can connect via port 80 to hotmail, gmail, yahoo or any number of free online webmail services, not to mention WebDAV connecting to Hotmail.

Microsoft did have plans to charge a nominal fee to connect to Hotmail using WebDAV (how Outlook connects to Hotmail) but AFAIK they never actually did it.

RE: Is it really that difficult?

Problem with blocking port 25 (some ISP's do that) is noone on your network can use other email services. In the case of 3rd party dedicated email, anti spam and antiviral services it breaks them. Everyone's locked into using ISP smtp servers which tend to die just when you really really need to send that email.

Why does it always have to be complicated?

No, it is far more simple than that.... In 2005 we had some widespread vulns which were easy to exploit. The lack of such easy ones now = less teenagers with zero morals in control of large bot nets, = less ddos attacks. Simple......
