To clarify, did you try this with a remotely hosted .html file or one on the local hard drive? Browsers treat this case specially and allow more access to the local filesystem. Putting an html file with an <img src="file:/&#x2F

Not widespread is a bit of an understatement. In the context of malware analysis I would be astonished if someone bothered to use a VM escape bug. They're valuable; you don't waste them by sticking them in a piece of malware to pw

I've tried that library, actually. Last time I used it, it couldn't find some passwords in the vault, including (crucially) the one I use for SSO at work. It's totally possible I was just using it wrong – it would be nice if

1Password didn't support Linux last time I checked. There are 3rd party libraries, but most of them don't support the newer keychain format. I still use it and just look up the password on my phone when I'm on a Linux system.

Really? Do you have an example of a substantial set of programs where that holds? I don't see a priori how it could work unless you can do exhaustive search over the space of all programs and determine if they halt and return the rig

No, this almost certainly isn't a preimage attack – it is more likely to be caused by the fact that you can generate MD5 collisions cheaply. Getting the gif animation to show the right frames based on the colliding block is a neat tric

It's not part of the IP packet, but in some previous cases exploits on Tor (such as the one the FBI used in the Freedom Hosting takedown) have explicitly queried the MAC address and then exfiltrated that information. I assume the inten

A nice complement to this article is the MIT 6.828 shell exercise. It provides the command loop and parsing for you, and then has you implement command execution, redirection, and pipes. https://pdos.csail.mit.edu/6.828&#x2F
