I recently wrote about ProtonVPN, a VPN services from the creators of ProtonMail. And for those of you that don’t know, ProtonMail is a service that provides security and encrypted emails.
If I can remember correctly I was part of the in initial launch and was in a waiting list for a free account. And this was only due to seeing some stuff on Twitter about it and letting my curiosity get the better of me, and I’m glad it did.
So what is ProtonMail, well to put it simply it is an encrypted email client that is based in Switzerland, and by just saying that you should know that the privacy and security of its user will be fantastic. This is largely due to Switzerland having some of the best laws in place for online privacy and security. So you know from the start that they are going to make sure your privacy is protected as strongly as possible.
Creating you ProtonMail account is much the same as creating any email account these days, you chose a username and set you passwords. But unlike the likes of Gmail and setting only one password ProtonMail asks for you to set an account password and then another password for your mailbox. This is a second line off defense to prevent your account being compromised. You can also set up 2 factor authentication from the security tab in the settings later. This again adds another layer of security before you can even view your inbox. And don’t worry this isn’t just some SMS verification, you can use just about any authenticator application on the market.
The web client its self looks just like any other email client, this I feel is a great thing because it feels as natural an environment as you’d likely be use to. Before using ProtonMail I was skeptical that the user interface might have been lacking in the looks department as their main priority is the security and protection of their users. But gladly this is not the case. There are 2 options for the layout of your inbox, the first displays your emails in a column on the left and then display the selected email on the right. And then the section option is to just have the list of emails and you can open the emails you wish to view. Depending on where you are when you are using this client could depend on how you have it laid out.
Recently I have started to use a new password manager and got asked why I did not just use the same password across all of my accounts online. And this lead to me thinking that people as a rule don’t know effective and secure practice to follow when using online accounts and passwords.
Firstly you should always use a different password for each of your online accounts, this could be having one password with many variations such as different letters or symbols within it. This is necessary these days as it only takes one of the platforms you use to get hacked and you could potentially lose access to all of your accounts.
So Here Are Some Good Password Practice
And hopefully if you follow some of the steps listed above you should be able to maximize your online security. As it is commonly known that the weakest point in most security systems is the human element. And that is because a lot of people have poor security knowledge or training. And this can be down to a number of thing such as age or use case.
But again hopefully this helps and you can share it with your friends and colleague to again increase everyone online safety.
In one of my recent post I explained and easy and safe way to set up your own Digital Forensics Lab and I mentioned a Linux based operating system by the name of Kali Linux. But what is it? and why would you use it in your virtual hacking lab?
Kali Linux is a Debian based operating system that uses the Gnome desktop environment, but unlike Ubuntu and Gnome Kali is packed full of usefully tools and applications for cyber security and digital forensics. Meaning that it is pretty much a one stop shop for just about any tools you could need, this makes things very convenient as you do not have to search around and download multiple applications they are already there in one place. It makes use of the Gnome menu system and groups all of the tools into named folders with the type of tool it is. This again means there is no hunting around when you have installed all of your tools.
There are a number off different use cases for a package such as Kali and the could be from a general curiosity to using it in industry as a professional. I personally use it along side my degree as is part of my course. But with it being free you can start using it when ever you want and with the many tutorial online it is really simple to get started and learn how to use it.
Because it uses the Gnome desktop it feels nice to use just like Ubuntu or Gnome, and it doesn’t feel like a tool your using. Granted a lot of people would be very unfamiliar with either of these Linux system but after a little bit it feels natural or like using any other graphical operating system. It also means that you could use it as a daily operating system if you were that way inclined. And don’t worry about requiring the latest computer hardware to run it because due to it being Linux based it doesn’t require all to much. Granted for certain task an application a little extra power wouldn’t go amiss but if you where to run it on 1 or 2 cores with 1 or 2 GB or ram it wouldn’t feel sluggish. And better yet you can run it live from a USB stick so you don’t even have to install it to benefit from it tools and features.
I tend to run it through a virtual machine, this is due to the safe lab that I mentioned before, and again it runs just like any other system within a VM. One benefit of doing this is that you can play around with the hardware the VM will supply it with. So if you have the hardware to spare you can build a beefy Kali System.
Tools Included in Kali
AirCrack is a WEP and WPA (Router Password) cracking tool, meaning that if you where preforming a penetration test on a company you may be able to gain access to there network through the WiFi.
This package allows you to test the security of web applications, it does this by canning the application the searches for possible vulnerability. This is a very helpful tool for developers who wish to make there product as secrecy as possible.
Hydra is a brute force password cracking application that on the surface looks limited and outdated. But in reality is a powerful tool allowing you to attack one or many users with either a single password or from a list of passwords.
John the Ripper
John the Ripper is another password cracking application that is command line based, although you can use a graphical version in the form of Jonny the ripper. It has been know for its speed at being able to crack passwords.
This is one that you are very unlikely to have used or heard of and it is Maltego, this application is an effective relationship tracker that can work on social media platforms, Computer networks and websites. Once it scans the target location it produces a map using graphics making it clear and easy to understand.
This is another application that works well for developers or system admin, Megasplot Framework runs simulated attacks on your network trying to find vulnerabilities. This allows you to patch or alter the vulnerability and make your system as secure as possible. And because it is all simulated there is no negative effects on the network its self.
Is another command line application that has a graphical front end application as well this time its in the form of Zenamp. The purpose of this tool is to preform network discover scan and also security auditing.
Zed Attack Proxy
The Zed Atatck Proxy or ZAP is another penetration testing tool targeting web applications, It supports the Open Web Application Security Project or OWASP and is pack to the brim with functionality and features.
Sqlmap is again a penetration testing tool but this time it is targeting SQL databases and looks for weakness in SQL injection, In some cases SQL injection can compromise an entire database. This could potentially leave the target in a whole heap of trouble.
Wireshark is a network protocol analyser, it boast some features such as being able to scan hundreds of protocols and preform offline analysis.
All of the above are aimed to provide a similar services to Kali Linux, and although I have limited hands on experience with each of them. I do know from others that they are good at what they do and that they should be considered as an alternative to Kali. Some of them are more tailored towards anonymity online while other are again forensics packages.
To those who are unfamiliar with the concept of full disk encryption it is very simple, normal your computer or mobile devices will store data on a HDD (Hard Disk Drive) without the requirement for a password or any verification to access it bar maybe a password to log into the machine. And this is all fine and well in a lot of cases, your average user might simply use there laptop for basic web browsing or to use services such as Netflix or Gmail.
But for some users personal or sensitive information might be stored on the computer, meaning that if the devise was to be stolen then all of this information could be accessed and could potently have massive consequences. But by using full disk encryption it makes it almost impossible to gain access to the drive and therefore the information stored on it. The best part is you don’t need to be “tech-savy” or a “computer genius” to achieve this level of protection. And it is also a huge amount easier to achieve than it might sound.
Firstly there are a number off different methods to protect your computer with full disk encryption, this could be in the form of a downloaded application but most operating systems these days also allow the user the ability to use full disk encryptions.
Listed below are a few of the easiest options to secure your PC with full disk encryption
Bit Locker is Microsoft Windows answer to full disk encryption, and was introduce with Windows Vista, but only on the higher tier packages such as professional and business. This could be a slight restriction to some users who have the home version of Windows.
But much it is a very effective and smooth process to encrypt your disk using Bit Locker, and with it being built it it is also very easy to set up and use. Unlike TrueCrypt this is ran through Microsoft, meaning constant updates and improvements to security and as a result making your data as safe as it can be.
Before Bit Locker was around full disk encryption was hard to come by, but there was an open source tool that gave users this ability. And this was TrueCrypt a very easy to use and secure full disk encryption software. That has unfortunately been unsupported since 2014. However your are still able to downloaded it, and even though it states on the website that you should migrate to Bit Locker I personally feel that for your average user that wants a little extra security it will still do an effective job. Largely due to the fact that if your devise was to get stolen, unless the thief was very technically able it would be incredibly challenging for anyone bar an expert to utilize the security vulnerabilities said to be within TrueCrypt.
Ubuntu Home Folder
If you are a Linux user then Ubuntu has you covered on the encrypted folder front, during the install process for Ubuntu you are given the option to password protect your home folder. If you opt to set up a password your home folder will then be encrypted requiring a password to access once logged into the system. It is really nice to see it in the installation stage as it means once your system has been installed everything is set up for you and you will not have to go and set it up after. Although if you use Ubuntu and didn’t do it during the start up, don’t worry about it because you can do it after while usng the system. There are guides to this on the official Ubuntu website.
In some cases there are different methods to unlock an encrypted drive, this could be done in a few different ways. One of the more popular is using a UBS drive as a decryption key. Meaning to access the encrypted drive the user will need to have access to the specific USB drive. This is very similar to using a key card to access the encrypted drive. In my opinion it is also a little bit more user friendly as you will not have to keep typing out what should hopefully be a lengthy and complicated password.
And one of my personal favourites is the use of biometrics such as a finger print scanner. These can be purchased online and with a little but of work in some cases, allows the user to have a scanner on the desk, and once a finger print is detected open the encrypted drive.
There are also other methods to be able to add secure sections to your files system, one I have a lot of experience with is use BitDefender. The BitDefender has an option to protect certain folders, Essentially setting up an encrypted location that requires a password to access, although it is not quite full disk encryption its a very easy and manageable way to secure some of your files. It also requires the user to select how much space is going to be need meaning that the area that you secure could be a large as you need.
