Comcast Warns Customers Suspected of Bot Infection
eldavojohn writes "Comcast is pushing a new program nationwide that warns customers if they might have a bot infection. It puts a semitransparent overlay on the top of the website you're viewing, warning you that you may have a bot installed if the provider detects botnet traffic from your residence. Of course, if you have multiple machines running behind a router or modem then you're going to have a difficult time pinning down which machine might have the infection."
They do send an e-mail, at first. If the traffic continues unabated, they redirect port 80 traffic (only) through a proxy which adds the notice to the server response (the web page you request). It doesn't break or tamper with anything else.
Personally, I don't see a problem with this, since, if you're allowing botnet traffic, you're already abusing the TOS (with or without your knowledge -- and after the notice, certainly ignorance isn't an excuse), and as such you're not really entitled to "unbroken" service, or any service at all for that matter. I think providing this notice is a good compromise.
Rather than making a separate post, I also want to address one of the points in TFS: "Of course, if you have multiple machines running behind a router or modem then you're going to have a difficult time pinning down which machine might have the infection."
This is rather missing the point -- realistically, if any machine inside your network has been compromised, you should assume that the entire network has been compromised, and you should be inspecting/sanitizing/protecting all of the machines accordingly. You should likewise assume that all of your online accounts have been compromised, change your passwords from a trusted location, and check for any unauthorized activity.
