We keep hearing about the security breach and hacking attacks on various devices like security surveillance systems, email accounts etc. These attacks or breaches compromise the private data, which can then be used for malicious purposes. To safeguard our systems from these attacks, we protect our systems with passcodes. It is important to understand what type of attacks are generally made by hackers so that we can choose the passwords accordingly.

Some of the common password cracking techniques used are:


This is the most common mode of Operandi to target unsuspecting and novice people. Here the hacker sends a phishing email, which leads the reader to a fake login page. When the reader logs in on this fake page with their user id and password, the page skims through this information and the hacker gets access to it.  So, in this mode of Operandi, the hacker asks you for your password and you give it willingly without smelling anything fishy. To prevent this, be wary of any email link that comes to your inbox and don’t click on it unmindfully.


There are malware attacks when something like a keylogger is installed on your system, which records things you type in a file and forwards it to the hacker. It can hack the passwords saved in the browsing history. To safeguard your devices against the malware attack, keep your device software updated.

Dictionary Attack

Keeping words found in a dictionary for passcodes can be easily cracked using dictionary attack. Thus, using simple words or even clubbing the words comprising only of alphabets will make your system prone to getting hacked. Thus, you need to have a password that is a combination of numbers, alphabets, and special characters.

Brute Force Attack

This is slightly more advanced than dictionary attack, which lets the hacker check for all possible alpha-numeric combinations. This includes all non-dictionary words like using sss3, tydt33 etc. This attack takes time to break the code if you have kept a long one with a combination of alphabets and numbers. However, professional hackers use additional computing horsepower to shorten the hacking time.

The hackers keep coming up with new and innovative ways to breach the security of devices. Though none of the device is completely immune to these attacks, keeping a strong password, updating the software, being vigilant by not revealing the passwords, and not falling for phishing emails can help in remaining safe.
