What is Credential Harvesting vs Password Spraying? Stay Safe Online.


Updated on:

I have seen firsthand the increasing sophistication of cyber attacks. One of the most dangerous tactics used by hackers is credential harvesting and password spraying. It’s crucial to understand the difference between these two methods of attack to better protect yourself against them and stay safe online.

Credential harvesting involves stealing username and password combinations by targeting legitimate websites and services. Hackers will use phishing emails, fake login pages, or malware to trick users into entering their credentials. Once the hackers obtain this information, they can use it to gain unauthorized access to other websites and services.

On the other hand, password spraying involves using a large list of common passwords and trying them on multiple accounts. This method relies on the fact that many people use simple, easily guessable passwords. The attackers can then gain access to a large number of user accounts with minimal effort.

It’s essential to understand these two methods and how they differ to protect yourself from falling prey to them. By using strong and unique passwords for each account, enabling two-factor authentication, and being mindful of suspicious emails and login pages, you can significantly reduce your risk of becoming a victim of credential harvesting and password spraying attacks.

Stay vigilant and stay safe online.

What is credential harvesting vs password spraying?

Credential harvesting and password spraying are two common techniques used by hackers to gain unauthorized access to user accounts. While both methods involve attempting to guess user credentials, there are key differences between the two.

  • Credential harvesting involves obtaining a set of legitimate login credentials from a breached website or database. These credentials are then used to gain access to other accounts of the same user or accounts that use similar login credentials.
  • Password spraying, on the other hand, is a brute-force attack in which hackers try to access an account using commonly used passwords. They do not possess or use any specific login credentials, rather they rely on a list of commonly used passwords to guess the correct combination.

Both credential harvesting and password spraying have proven to be effective methods for hackers to compromise user accounts. It is important for users to practice good password hygiene, including regularly changing passwords and avoiding common password choices such as “password” or “12345678”. it is also important to implement multi-factor authentication and educate users on the risks associated with weak passwords and the importance of protecting their login credentials.

???? Pro Tips:

1. Use a strong, unique password for each online account to make password spraying more difficult.
2. Be mindful of phishing scams that may use credential harvesting techniques to steal login information.
3. Utilize multi-factor authentication to provide an extra layer of security against both password spraying and credential harvesting attempts.
4. Keep all software and systems updated to prevent attackers from exploiting known vulnerabilities.
5. Monitor login attempts and suspicious activity on accounts in order to catch and respond to potential attacks early on.

What is Credential Harvesting vs Password Spraying?

it’s essential to understand the different methods used by cybercriminals to steal login credentials. Credential harvesting and password spraying are two popular techniques used by hackers to gain access to sensitive information. Though they may sound similar, these attacks operate differently and require distinct security measures to protect against them.

Understanding Credential Harvesting

Credential harvesting, also known as phishing, is an attack that uses email, text messages, or other communication methods to trick users into surrendering their account information. Often, the hacker creates a fake login page designed to look like a legitimate site, such as an email service provider or social media platform. Once the user enters their login credentials, the attacker now has the ability to access the user’s accounts and sensitive information.

Phishing attacks have become increasingly sophisticated over time, with attackers often using AI-generated content to create more convincing bogus emails and web pages. This type of attack targets users with a convincing simulation of a legitimate password reset request, system upgrade alert, or even a fake job inquiry.

How Credential Stuffing Works

In some cases, attackers don’t need to resort to phishing to gain access to sensitive data. Once hackers acquire a set of legitimate login credentials, they can attempt to use them to gain access to other accounts in a process called credential stuffing.

Credential stuffing attackers can take advantage of users who reuse the same password across multiple accounts. By using automated scripts, bots, and other tools like proxies to prevent detection, they can try username and password combinations on other websites. The technique works because many users reuse the same password across sites, making it easy for attackers to gain entry into additional accounts.

The Dangers of Credential Stuffing

The consequences of credential stuffing can be disastrous for users and companies alike. Once attackers gain access to a user’s credentials, they can steal sensitive data, drain bank accounts, and create havoc with identity theft.

In addition to stealing user data, credential stuffing attacks can negatively affect businesses and organizations’ overall security posture. If hackers gain access to multiple employee accounts, they can easily escalate their access to back-end company systems, causing significant breaches and other malfeasance.

What is Password Spraying?

Password spraying is a brute force attack where hackers use a list of commonly used passwords to attempt entry on multiple accounts. Unlike credential harvesting, where the attackers have access to a single user’s specific login credentials, this type of attack is targeted towards commonly occurring passwords that users share across multiple accounts.

The two primary types of password spraying attacks are untargeted and targeted. Untargeted password spraying involves trying out the same list of passwords across all accounts without specific targets. In contrast, targeted password spraying involves a more sophisticated approach of trying out password combinations based on specific users or account names.

The Mechanics of Password Spraying Attacks

Hackers use automated tools to conduct password spraying attacks. These tools can test thousands of usernames and password combinations in a short period, increasing the chances of successful entry. Additionally, hackers use methods such as proxy servers to rotate IP addresses to prevent lockouts.

Password spraying attacks are highly successful primarily due to the commonality of easy-to-guess passwords such as “password” or frequently used words like “qwerty.” It is a warning to users to avoid such easy-to-guess password practices and instead adopt complex security measures, such as multi-factor authentication techniques.

Why Password Spraying Can be Successful

Password spraying can be highly successful because many users use the same password across various accounts, making it easy for hackers to use those credentials to gain access to additional systems. Moreover, it becomes easier for cybercriminals to create a targeted password spraying attack using a small number of usernames.

Tips for Protecting Against Credential Harvesting and Password Spraying

Here are some essential tips for both individuals and organizations to protect against credential harvesting and password spraying attacks:

  • Regularly update passwords and avoid reusing passwords across multiple accounts.
  • Enable multi-factor authentication whenever available.
  • Use complex passwords that include alphanumeric characters, special characters, and symbols.
  • Deploy anti-phishing and anti-malware solutions.
  • Provide employee awareness training on cybersecurity practices and phishing attacks.
  • Use password managers and instructions for employees to maintain their password management hygiene.

In conclusion, cybercriminals use numerous tactics to steal login credentials. While protecting against both credential harvesting and password spraying attacks is necessary, companies must deploy a multi-faceted approach to security, train employees, and implement security policies and procedures. Additionally, users should take measures to ensure their online accounts’ security, including regularly updating their passwords and enabling multi-factor authentication whenever possible. By following these security best practices, individuals and businesses can significantly minimize their risk of falling victim to cyber-attacks.
