A strong password plays a crucial role in safeguarding your personal and sensitive information against unauthorized access, preventing password breaches, compromised passwords, and password leaks. Hackers and cybercriminals employ various techniques to hack passwords, including dictionary attacks, brute force attacks, and social engineering. Password security and password protection serve as fundamental practices for confirming identity and limiting access to devices, files, and accounts, thereby guaranteeing access only to individuals who can provide the correct password in response to a prompt. It's also important to consider implementing two-factor authentication for enhanced security.
How Do Passwords Get Breached?

A. Password cracking techniques
Password cracking involves two main approaches utilized by password crackers: brute force and dictionary attacks. Nevertheless, there exist numerous other techniques for password cracking. In this article, we will explore three significant ways in which passwords are compromised.
- 1. Brute force attacks
Brute force attacks involve hackers systematically attempting various username and password combinations, using methods like dictionary attacks and simple brute force to crack passwords and gain unauthorized access to accounts and systems. These attacks persist as a popular choice among cybercriminals due to their effectiveness.
The types of brute force attacks include simple brute force attacks, dictionary attacks, hybrid brute force attacks, reverse brute force attacks, and credential stuffing. Each of these methods targets weak or reused passwords, emphasizing the importance of strong password practices and robust security measures.
- 2. Dictionary attacks
A Dictionary Attack, a variant of the Brute Force Attack, involves attempting every word in a prepared dictionary as a possible password to breach password-protected systems. This dictionary comprises words from the English language and commonly used passwords, often modified with character replacements for added complexity, making it a fast and effective approach. Automated tools like John the Ripper, L0phtCrack, and Aircrack-ng are commonly used for executing dictionary attacks.
- 3. Rainbow table attacks
A rainbow table attack constitutes a password cracking technique employing a specialized table, the "rainbow table," to decrypt password hashes stored in databases. Instead of saving passwords in plain text, applications encrypt them using hashes. When a user logs in, their password is hashed and compared to stored hashes on the server. A match grants access.
The rainbow table contains precomputed password hash values for each plaintext character used in authentication. To execute this method, hackers must first obtain leaked password hashes, often due to poor security measures or phishing techniques. This technique is favored by hackers as it offers a quick way to decrypt passwords, enabling unauthorized access.
Rainbow tables are efficient in terms of computing power but require substantial storage space. In real-world scenarios, attackers exploit outdated hashing techniques, making salting, multifactor authentication, avoidance of obsolete algorithms, and server monitoring essential to prevent rainbow table attacks.

B. Social engineering
Social engineering involves the art of manipulating, influencing, or duping a target with the intention of assuming control over a computer system or extracting personal and financial data. This technique relies on psychological manipulation to deceive users into committing security errors or divulging sensitive information.
-
1. Phishing
Phishing attacks, a prevalent form of social engineering, involve deceptive emails, texts, calls, or websites aimed at luring users into downloading malware, divulging sensitive data, or taking actions that expose them and their organizations to cybercrime risks.
Successful phishing attacks often result in identity theft, credit card fraud, ransomware incidents, data breaches, and substantial financial losses for individuals and corporations. These attacks rely on human error and pressure tactics, with attackers posing as trusted entities, such as coworkers or reputable organizations, to create a sense of urgency that leads victims to act impulsively.
Hackers favor these methods for their cost-effectiveness in comparison to hacking into computer systems or networks. According to the FBI, phishing emails are the most popular method used by hackers to distribute ransomware, and IBM's 2022 Cost of a Data Breach report indicates that phishing is the second most common cause of data breaches, with phishing-related breaches being the costliest, averaging USD 4.91 million in damages.
-
2. Impersonation
Impersonation attacks, a form of targeted phishing, involve malicious actors assuming false identities or impersonating entities to employ social engineering tactics in the theft of sensitive data from unsuspecting employees. Hackers aim to deceive victims into transferring funds, disclosing sensitive information, or surrendering business login credentials, enabling them to execute cyberattacks and gain illicit access to systems and networks.
One example is the business email compromise (BEC), wherein criminals employ fake emails, often through spoofing or hacking, mimicking high-level executives or vital business entities to trick targets into initiating financial transfers or revealing critical information. Notably, high-ranking employees receive approximately one impersonation attempt every month, underscoring the prevalence of this threat.

What Happens if My Passwords Get Breached?
When your passwords are breached, the consequences can be severe, impacting your privacy and finances. Cybercriminals who steal your data can exploit it to access multiple accounts, particularly if you reuse or slightly modify passwords.
Furthermore, password breaches can result in cybercriminals blackmailing you or engaging in identity theft. For instance, if a cybercriminal were to breach your email password, and you lacked multi-factor authentication, they could potentially reset passwords for other accounts associated with that email address, further exacerbating the risk.
How To Prevent Your Passwords From Being Breached
To safeguard your passwords from breaches, consider employing a password manager, enabling Multi-Factor Authentication (MFA), and steering clear of public WiFi networks.
A password manager serves as a crucial tool for generating, managing, and securely storing your passwords, ensuring they align with best practices and aren't reused. MFA, on the other hand, offers an added layer of protection by requiring multiple methods of authentication, thwarting unauthorized access even if your passwords are compromised.
Public WiFi networks should be avoided as they pose a vulnerability to Man-in-the-Middle (MITM) attacks that can intercept your data during transmission. These precautions collectively fortify your online security and minimize the risk of password breaches.
