These past few days I decided to take a look at perhaps my weakest topic in computer science: Computer Architecture. There is something about these abstract concepts that I have struggled to wrap my head around in the past. So once and for all, I will delve into some of the basics of computer architecture […]
I often find myself forgetting a lot about certain topics in cybersecurity that I have studied at some point. I recently revisited basic encryption concepts which led me down a rabbit hole this past weekend. Today’s blog post will cover what I studied; this includes symmetric encryption, asymmetric encryption, Diffie-Hellman Key Exchange, TLS Handshake, Kerberos, […]
What Is Risk Analysis? Risk analysis is a part of the risk assessment process (itself being a stage of the risk management process) which involves evaluating potential risks to determine their impact and likelihood to occur. Below I have made a list of the steps in the risk management process and some of the processes […]
What is Incident Response? Incident response is a set of rules and procedures that are used to identify, contain, and eliminate cybersecurity incidents. An incident is a detrimental event to the company that requires immediate prevention, containment, eradication, and remediation steps to be implemented. The 6 Phases of an IRP When an incident occurs, it […]
Welcome to another post about anything somewhat related to IT. A couple of weeks ago, I was guessing recruiters’ work email addresses (a typical Friday evening hobby of course) when I received an automated email back which informed me that the recipient could not receive my email since their domain did not accept emails from […]
Today I will be talking about Voice over Internet Protocol (VoIP). I was vaguely aware of what VoIP technology was about before reading into it for this blog but a lot of this is new to me. I am going to do my best to explain what I have learnt, and why it is important. […]
Welcome to another blog post! I have been going back over some of the basics in computer networking and I wanted to take this opportunity to make a few written pieces on what I have been (re)learning. This is primarily for two reasons. The first being that it’s a great way of reinforcing what I […]
mkdir regular syntax. mkdir -p syntax. -p = Parent directory Syntax to create a chain of child directories. Syntax to create more than one directory at a specific level. Just a fun tidbit that makes life a bit more efficient on Linux!
1) Check Crackstation https://crackstation.net/ It will be able to crack very simple hashes. 2) Identify Hash Type (and Salt) HashID (https://github.com/psypanda/hashID) Note: This requires Python. You can install it like so: $ pip install hashid Syntax $ python -m hashid [OPTIONS] [HASH] None of the options are necessary so I won’t write them out. Plus, […]
Introduction Today I will be going over Overpass 3, a moderately challenging CTF on TryHackMe. Let’s get right into it! Overpass 3 room: https://tryhackme.com/room/overpass3hosting Deploy the target machine and connect to the TryHackMe network with OpenVPN. Port Scans Let’s make a directory for this CTF and create a directory underneath that for our port scans. […]
