comment Are there any known Heartbleed attacks?
Nice try, FBI. No but seriously, I don't think the kind of people that go around trying to exploit the internet are going to visit this site and tell you about it.

comment Why are apps for mobile devices more restrictive than for desktop?
First thought: Because they were designed far more recently with more modern needs in mind, and desktop OSes have yet to catch up.

comment Is Telegram secure?
@TerryChia I understand your point, and I too distrust any crypto in new apps, but I don't think this is the major concern when using Telegram right now. The protocol has been looked at by a few smart people and so far I've yet to hear actual issues, so that in my opinion that moves it from "distrusted" to "probably one of the lesser issues". Things like not having plausible deniability, leaking metadata, devices being pwned, people not comparing the encryption key out of band, etc. seem like much bigger issues when deciding whether one should say product X can be ultimately trusted.

comment Is Telegram secure?
In short, I'd say nothing is secure that works as easy as Telegram, WhatsApp, Skype, BlackBerry, etc. All of those (except WhatsApp) have promised end to end encryption, and so far only Telegram is not known to hand over their encryption keys to governments, simply because they are not big enough yet. Somehow Microsoft and Blackberry made it possible to break their own security and provide India and the United Arab Emirates with some plaintext. I wouldn't put it past any app to do this. For real security, use trusted tools like PGP/GPG or OTR.

comment Is Telegram secure?
Reiterates lots of the criticism, but so far I have yet to hear a non-theoretical vulnerability. Can anyone read encrypted messages as they go over the wire, change contents without the other party noticing (even if the attacker doesn't know what the decrypted output will be), or spoof the sender? If not, I don't see a problem with this self-designed protocol. All protocols have been designed by one team or another at some point.

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/TLS 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/*).
