But aside from that, could your network be even MORE vulnerable? Hard to imagine right? But check out Georges latest post where he discusses how default SNMP strings could further add to the issue, leaving your network open to some major issues.

Nice find George! Great way to dig deep, find an issue, and teach people what they should do to correct the issue. It shows that you care about the technology and what can happen if you just take shortcuts (like leaving SNMP strings with default values) to get things up an running in a hurry.
