For those of you who haven't a clue about this, I looked it up.
The DNSChanger virus/malware has been around for a while. It's not the only one capable of it, it's just the most prevalent.
As a way to counter-act it, the FBI has had a series of servers that have watched for it and acted against it. However, due to funding, those servers are being shut down in July. (Google "Operation Ghost Click")
Meanwhile, they are just now starting the arrests and charges against the idiots who started it.
There's several of these things out but DNSChanger seems to be the most active. There's websites that will check your DNS number for validity. I was skeptical at first so I checked it all out before I clicked away.
Your computer has an IP address
of its very own. Each computer, cell phone, tablet, whatever that connects to the 'net has it's own IP address. Sometimes that address changes but that's another topic. Consider the IP address to be a phone number and only that device has that number. Each website also has an IP number.
DNS is Domain Name System
and you can consider it to be the phone book. Basically, you type in apneaboard.com (it's domain name) but in the magic of the internet, that text is translated to the IP address, located, and you are connected to the website. There's a lot of other steps in there and it is amazing it all happens as fast as it does. It is a delicate balance of domain names, servers, internet providers, your computer, and other stuff.
Quote:The group that created Zlob have also created a Mac trojan with similar behaviours (named RSPlug). Some variants of the Zlob family, like the so-called "DNSChanger", add rogue DNS name servers to the registry of Windows-based computers and attempt to hack into any detected router to change the DNS settings and therefore could potentially re-route traffic from legitimate web sites to other suspicious web sites.
The way to avoid these things? Don't download stuff you are not sure of the source. Most of these were delivered via downloaded video which gave a pop up warning of a virus which had you click a button. Instead of fixing this fake virus, it gave you a real one. Ironic, isn't it?
