Both Debian and BSD you can use lsof command. In your articular case, you can run: lsof | grep -i "AppleCamera" Documentation of lsof related to your OS.

Even if Tails offers anonymity and coming with default built-in encryption suites for different purposes, your anonymity is already compromised since as in all schools/universities we find the same policy: to use their WiFi they need to be sure you are either a student, a teacher or an authorized person to access their Wifi. Also you must remember that ...

There are two general categories of vulnerability to your anonymity that I would be concerned with given that setup: Using web sites that identify you (it's a moot point if you then go log into Facebook with your real name!) Traffic analysis - if your school requires login info specific to you, then the school knows who's sending the traffic, and if they ...

This seems to be a bug in Chrome. Root CA Certificates are often still SHA-1 certificates, which is not a security problem (and also not considered a problem by Google: http://googleonlinesecurity.blogspot.ca/2014/09/gradually-sunsetting-sha-1.html), yet Chrome spooks users with the warning - even when the only SHA-1 certificate in the chain is the root CA ...

You say "SSH is fast". It's not. It's fast enough for its intended purpose (remote shell access and occasional file transfer/sshfs) but it's definitely not fast enough for IPC, let alone efficient. On a local machine there's never any need for encryption between processes. If an attacker can read what you're sending to localhost, he can most definitely read ...

newgrp is a UNIX utility that executes a shell with a new group ID (see the UNIX specification page). This utility requires root permission since it can change the group ID to one outside the current shell's group list (e.g. to any group in the uid's group list). Therefore, newgrp is a setuid root application which launches a shell. DYLD_PRINT_TO_FILE is a ...

The first important thing is to think about the meaning of this security hole. This is a local privilege escalation: if an attacker can get to run code of his choosing on the machine, with "normal" privileges, then that attacker can use this hole to obtain more extended privileges on that machine. In general, for a desktop system, when attackers can run ...

Analysis When setting: DYLD_PRINT_TO_FILE=/tmp/log some_command the MacOS X dynamic loader will open /tmp/log as a log file, i.e. with append access to potentially debug problems within the dynamic loader. This file is open with the first free file descriptor in the shell calling context which is 3. Hence the file descriptors associations are: 0 → ...

I've checked All the websites You've mentioned using an online SHA Checker Tool - https://shachecker.com. As per the result none on this website found with the older SHA-1 algorithms. All seems okay with SHA-2 encryption. This problem might be from Google Chrome or from your MAC device.
