comment Security of a Windows XP system after April 8th when running the latest Firefox or Chrome
"XP has had enough holes over the years that it's hard to imagine there aren't some un-found holes in what remains." I understand that, but you'll need to somehow reach the system to exploit it. So if the browser is the only way, and it's a modern and up-to-date browser... That's what I'm asking about. "an installation of linux" I've thought of that, but Windows 8 on her work laptop is a huge change already. I'll use this as a last resort. Thanks for the suggestion though!

Third party anti-virus already installed for the same reason as a third-party browser. EMET may be a good idea though, thanks!

comment How does SSL work?
@RosdiKasim Yes, you can do that easily. Data is unencrypted and can be manipulated until right before it is transmitted. That's the risk behind installing plugins. Rogue plugins are basically the same as running a virus with user (non-adminstrator) permissions: it may be confined to your user account, but it can still log all your keys (keylogger). In the case of a browser plugin it is confined to your browser, but it can still get all website's data (including passwords when you type them in).

comment Finding Hidden Keylogger Through Forcing a Computation Error
"Maybe this is something a bit higher than what most people on this site are able to answer" Honestly I think it's more beyond your comprehension, not the people on this site. It was a good laugh though to read you filming a screen at 16k fps when it only refreshes 60-120 times a second. Edit: Also to answer your question: 1. you can tap a line without slowing it down, and 2. you can do software keyloggers without introducing delay since you read the key after-the-fact instead of intercepting it (sudo cat /dev/input/*).

comment How safe is SSL?
TL;DR: yes it is all encrypted and secure. Even if it wasn't, there is nothing you can do about it. Adding hashing via javascript adds no security to https.

comment Why warning sign when visiting https-website?
It's a lengthy piece, but the answer is in here: security.stackexchange.com/a/20833/10863. Under the section "How to crack SSL," subsection "in detail," paragraph 2, it is explained what causes this warning sign.

comment Is this where a nonce comes into play?
@user3379785 Note that comments aren't really meant for chatty back-and-forth stuff. The chat is usually recommended instead, but for some reason you need 20 reputation point to participate in the chat... If you have more questions on this topic you could email me or something. See https://lucb1e.com/!about for contact details. If you have a more general question (something that would be of use to others), you can always start a new question on this site.

comment Is this where a nonce comes into play?
@user3379785 The crux of the problem is that the GUID is both the unique way of referring to an account and it provides full access. So as long as the GUID can be used instead of username+password, I think the design could be improved (even if it's not directly broken, like I said in the post). You say the GUID is checked before API calls, but how is it checked? You mean the server checks whether the GUID matches the session's owner? So the GUID is not enough, you now also need to send the session id with API requests to control an account? In that case I think it's much more solid now :)
