comment What mechanism enforces user permissions in Unix/Linux?
@NathanLong Yep. A kernel-mode driver can totally ignore all forms of access control because it runs below that abstraction layer. An alternate OS would do the same because it doesn't recognise that access control mechanism.

comment Strange file named Aview.exe - WinClient
Sounds like it's either badly written, or badware. Since you've already sent it to VirusTotal, it'll be given to all the major AV vendors for analysis anyway.

comment How to evaluate the strength of a hashing algorithm?
To clarify your last requirement: changing one single bit of input should change all output bits with a probability of 50%. Another requirement is that the hash is, to the highest extent possible, statistically independent of the input, e.g. a high hamming weight in the input does not produce an abnormal hamming weight in the output.

comment How isolated are files on a VirtualBox virtual machine from the host filesystem?
@jmort253 At that point you're better off using shred or sdelete - encrypting it at that point is just needless computation.

comment Security threats of wireless charging?
As a quick summary: the device can only pull 100mA to 150mA without negotiation with the charger, so a device is required in order to perform that negotiation. Some modern devices don't require it, but many do. As such, there is often a transfer of data.

This actually isn't true, for the mostpart. Modern chargers are much more complicated.
