Learning How to Use Metasploit: Tutorial + Tips
The ease of learning to use Metasploit depends on your knowledge of Ruby. However, if you have a familiarity with other scripting and programming languages like Python, making the jump to working with Metasploit shouldn’t be too difficult to get up to speed. Otherwise, it’s an intuitive language that’s easy to learn with practice.
Because this tool requires you to disable your own systematic protections and enables the generation of malicious code, you should be aware of the potential risks involved. If possible, keep this utility installed on a separate system than your personal device or any computer that contains potentially sensitive information or access to such information. You should use a dedicated work device when pen-testing with Metasploit.

Potential Security Threats To Your Computer Systems @cmd_programming
A computer system threat is anything that leads to loss or corruption of data or physical damage to the hardware and/or infrastructure.
Knowing how to identify computer security threats is the first step in protecting computer systems. The threats could be intentional, accidental or caused by natural disasters.
In this article, we will introduce you to the common computer system threats and how you can protect systems against them.
@cmd_programming
What is a Security Threat?
Security Threat is defined as a risk that which can potentially harm computer systems and organization. The cause could be physical such as someone stealing a computer that contains vital data. The cause could also be non-physical such as a virus attack. In these tutorial series, we will define a threat as a potential attack from a hacker that can allow them to gain unauthorized access to a computer system.
@cmd_programming
What are Physical Threats?
A physical threat is a potential cause of an incident that may result in loss or physical damage to the computer systems.
The following list classifies the physical threats into three (3) main categories;
Internal: The threats include fire, unstable power supply, humidity in the rooms housing the hardware, etc.
External: These threats include Lightning, floods, earthquakes, etc.
Human: These threats include theft, vandalism of the infrastructure and/or hardware, disruption, accidental or intentional errors.
@cmd_programming
To protect computer systems from the above mentioned physical threats, an organization must have physical security control measures.
The following list shows some of the possible measures that can be taken:
Internal: Fire threats could be prevented by the use of automatic fire detectors and extinguishers that do not use water to put out a fire. The unstable power supply can be prevented by the use of voltage controllers. An air conditioner can be used to control the humidity in the computer room.
External: Lightning protection systems can be used to protect computer systems against such attacks. Lightning protection systems are not 100% perfect, but to a certain extent, they reduce the chances of Lightning causing damage. Housing computer systems in high lands are one of the possible ways of protecting systems against floods.
Humans: Threats such as theft can be prevented by use of locked doors and restricted access to computer rooms.
What are Non-physical threats?
A non-physical threat is a potential cause of an incident that may result in;
- Loss or corruption of system data
- Disrupt business operations that rely on computer systems
- Loss of sensitive information
- Illegal monitoring of activities on computer systems
- Cyber Security Breaches
- Others
@cmd_programming
The non-physical threats are also known as logical threats. The following list is the common types of non-physical threats;
- Virus
- Trojans
- Worms
- Spyware
- Key loggers
- Adware
- Denial of Service Attacks
- Distributed Denial of Service Attacks
- Unauthorized access to computer systems resources such as data
- Phishing
- Other Computer Security Risks
@cmd_programming
To protect computer systems from the above-mentioned threats, an organization must have logical security measures in place. The following list shows some of the possible measures that can be taken to protect cyber security threats.
To protect against viruses, Trojans, worms, etc. an organization can use anti-virus software. In additional to the anti-virus software, an organization can also have control measures on the usage of external storage devices and visiting the website that is most likely to download unauthorized programs onto the user’s computer.

How to Crack a Password
What is Password Cracking?
Password cracking is the process of attempting to gain Unauthorized access to restricted systems using common passwords or algorithms that guess passwords. In other words, it’s an art of obtaining the correct password that gives access to a system protected by an authentication method.
Password cracking employs a number of techniques to achieve its goals. The cracking process can involve either comparing stored passwords against word list or use algorithms to generate passwords that match
What is password strength?
Password strength is the measure of a password’s efficiency to resist password cracking attacks.
The strength of a password is determined by;
- Length: the number of characters the password contains.
- Complexity: does it use a combination of letters, numbers, and symbol?
- Unpredictability: is it something that can be guessed easily by an attacker?
Let’s now look at a practical example. We will use three passwords namely
1. password
2. password1
3. #password1$
The 3rd is long, complex and unpredictable more than the 1st and the 2nd.

Password cracking techniques @cmd_programming
There are a number of techniques that can be used to crack passwords. We will describe the most commonly used ones below;
- Dictionary attack– This method involves the use of a wordlist to compare against user passwords.
@cmd_programming
- Brute force attack– This method is similar to the dictionary attack. Brute force attacks use algorithms that combine alpha-numeric characters and symbols to come up with passwords for the attack. For example, a password of the value “password” can also be tried as p@$$word using the brute force attack.
@cmd_programming
- Rainbow table attack– This method uses pre-computed hashes. Let’s assume that we have a database which stores passwords as md5 hashes. We can create another database that has md5 hashes of commonly used passwords. We can then compare the password hash we have against the stored hashes in the database. If a match is found, then we have the password.
@cmd_programming
- Guess– As the name suggests, this method involves guessing. Passwords such as qwerty, password, admin, etc. are commonly used or set as default passwords. If they have not been changed or if the user is careless when selecting passwords, then they can be easily compromised.
@cmd_programming
- Spidering– Most organizations use passwords that contain company information. This information can be found on company websites, social media such as Facebook, twitter, etc. Spidering gathers information from these sources to come up with word lists. The word list is then used to perform dictionary and brute force attacks.

There are a number of techniques that can be used to crack passwords. We will describe the most commonly used ones below;
- Dictionary attack– This method involves the use of a wordlist to compare against user passwords.
@cmd_programming
- Brute force attack– This method is similar to the dictionary attack. Brute force attacks use algorithms that combine alpha-numeric characters and symbols to come up with passwords for the attack. For example, a password of the value “password” can also be tried as p@$$word using the brute force attack.
@cmd_programming
- Rainbow table attack– This method uses pre-computed hashes. Let’s assume that we have a database which stores passwords as md5 hashes. We can create another database that has md5 hashes of commonly used passwords. We can then compare the password hash we have against the stored hashes in the database. If a match is found, then we have the password.

- Guess– As the name suggests, this method involves guessing. Passwords such as qwerty, password, admin, etc. are commonly used or set as default passwords. If they have not been changed or if the user is careless when selecting passwords, then they can be easily compromised.
