One may have asked, "How do hackers take my password, if the website owner can't?" The answer is simple. When a website stores your login password for the site, it is run through a cryptographic hash function before it enters the database.  So how do hackers get these passwords?  When a website is breached and has their database stolen, the password hashes will be in there. A hacker will analyze the hashes, and see which   hash type   they are, and then bruteforce them. Bruteforcing is when you systematically cycle through each letter in a letterset until it matches a password. A letter set can be all lower-case, upper-case, symbols or anything the hacker wants. So the hacker bruteforces until they find a hash that matches yours, resulting in "guessing" your password. I dedicate this tutorial for anyone who wants to understand password attack vectors and those training for careers in cyber security.  L ets run through what it takes to hack a password using the c...

Hackers have access over 7.9 billion consumer records so far this year with experts predicting that over 8.5 billion accounts will be exposed by the end of the year. The majority of the over 5,000 data hacks last year  Risk Based Security has tracked so far   consisted of only a few million accounts. Yet there were a few mega hacks that involved hundreds of millions.      Step 1 Make Sure Your Passwords Is Unique  Meaning, do NOT reuse passwords on other sites or applications. If one of the sites gets hacked, that means an attacker has your login information for other sites, as well. And they can reset your passwords anywhere and take control of your data. However, this can be a really tough task if you've created hundreds of accounts online, which is becoming the norm these days. If you just can't help yourself from reusing passwords, make sure you at least create unique ones for the important ones, i.e. email accounts, social networking sites (like Facebo...

Welcome back! Today,  I'm offering this guide on Linux networking. I assume that you understand a small amount of networking concepts, things like IP addresses, MAC addresses, DNS, DHCP, etc. If not, please take some time to pick up a few networking basics in my previous articles on networking.  Step 1 Analyzing Networks The most basic linux command for analyzing networks is  ifconfig . It's very similar to the Windows command  ipconfig . Let's take a look at it. sudo ifconfig As you can see in this screenshot,  ifconfig  conveys a significant amount of information to the user. In the very first line, we see to the far left  eth0 . This is the first  wired  network connection,  ether net 0 (Linux usually starts counting at 0). Following this, we see the type of  network  being used (Ethernet) and the  hardware address  (this is the globally unique address stamped on every piece of network hardware, in this case the NI...
