I wish I could say that this was the worst article I've ever seen about a security breach, but it isn't. It suffers from a common flaw with such articles in the mainstream press. It mentions a virus without mentioning what it infects. Odds are that it targets Windows or something running on it, but that isn't a sure bet. Given that it's grabbing login credentials for websites, it could be browser malware instead.
My jaw hit the floor when I saw this: "FTP, the standard network used when working from home". FTP is a protocol, not a network. Okay, that point is going to be lost on many end users. However, statements that make it less clear to anyone whether they are vulnerable don't actually help anyone.
Anyway, if you're concerned and use any of the online services listed, or any other common cloud services for that matter, the simple answer is to change your password through a computer whose security you are confident hasn't been compromised.http://money.cnn.com/2013/12/04/technology/security/passwords-stolen/index.html?fb_action_ids=10201865350907489&fb_action_types=og.recommends&fb_source=other_multiline&action_object_map=%5B675830019115657%5D&action_type_map=%5B%22og.recommends%22%5D&action_ref_map=%5B%5D
