And yet the best part is...
...that almost everyone so far has merely scoffed at the very idea of a threat to Linux, and not once suggested that users should go and double check their software to make sure it's all as secure as can be. It only takes one new or clueless user to leave something open by accident and then, whoops, you're now part of the problem.
Of course, that that point no-one will offer any help or support, just merely scoff again and deride them for such a 'basic' mistake.
So, to make up for this... any and all intelligent sys-admins and users, do yourselves a favour, and go review your security settings. You can't be too careful now, can you?
