WordPress Security: Someone is trying to login to my website. Who and Why?

Preventing WordPress Brute Force Attacks - WordPress Security Tips

One concerning issue faced by many WordPress website owners is repeated login attempts by unauthorised parties. Our Sydney WordPress developers have over 18 years experience managing WordPress websites for clients of all sizes and we regularly get asked why so many login attempts are showing up in the website’s logs. Here we look at who could be responsible, why it’s happening and what your can do to ensure your WordPress security protocols are able to prevent those attacks from breaching your website.

Introduction

The Internet is teeming with cyber threats, and unauthorised login attempts on WordPress websites are a significant concern. As a WordPess website owner, it’s essential to understand the potential risks associated with repeated login attempts and take appropriate measures to protect your online presence. While WordPress can be attacked a lot – so to are other website technologies – but the benefit of developing your website with WordPress is the amount of free tools available that will help you harden your WordPress security.

Understanding the Threat of Unauthorised Login Attempts

Unauthorised login attempts occur when someone tries to gain access to your WordPress website using incorrect login credentials. These attempts can be a result of various factors, including:

1. Brute Force Attacks

Brute force attacks target the heart of WordPress security by capitalising on the weakest link—the human factor. Attackers understand that many users resort to using simplistic, easily memorable passwords or default usernames, such as “admin” or “user.” Armed with specialised software or scripts, hackers unleash a relentless barrage of login attempts, systematically cycling through a vast array of potential username and password combinations.

The power of automation is a key element in the effectiveness of brute force attacks. Automated programs can rapidly generate and test an immense number of password combinations within a short span of time. This exponential increase in attempts allows attackers to exploit the odds, hoping to stumble upon the correct credentials that will grant them unauthorised access.

2. Targeted Attacks

WordPress security must be fortified against targeted attacks, which represent a more sophisticated and direct assault on the integrity of your website. Unlike brute force attacks, targeted attacks are carefully planned and executed by skilled hackers who possess the expertise to exploit vulnerabilities and breach your website’s security defenses.

Targeted attacks are not random acts but instead focus on specific websites or individuals. Hackers may specifically target your WordPress website due to its popularity, valuable data, or potential financial gains. These attacks are often conducted by individuals or groups who possess an in-depth understanding of the intricacies of WordPress and its underlying infrastructure.

To achieve their malicious objectives, hackers employ a range of sophisticated techniques and strategies. One common approach is to exploit known vulnerabilities in outdated versions of WordPress or its plugins. By identifying these weaknesses, attackers can gain unauthorised access and potentially manipulate or extract sensitive data.

Another method employed in targeted attacks is social engineering. Hackers may craft convincing phishing emails or messages that appear legitimate, tricking unsuspecting users into disclosing their login credentials or downloading malware-infected files. These tactics leverage psychological manipulation to deceive individuals and compromise the security of their WordPress websites.

3. Password Spraying

Another frequent attempt at compromising your WordPress security is password spraying, a technique employed by attackers to compromise the security of multiple accounts. In password spraying attacks, hackers use a limited set of commonly used passwords and systematically try them across numerous accounts, including WordPress websites. This method enables them to bypass detection systems that typically block repeated login attempts.

Unlike brute force attacks that aim to crack a specific account by trying various combinations of usernames and passwords, password spraying takes a different approach. Attackers select a handful of frequently used or easily guessable passwords, such as “password123” or “123456,” and test them against multiple accounts simultaneously. By using a small number of passwords, they reduce the likelihood of being detected by systems that track and block repeated login attempts.

The success of password spraying attacks hinges on several factors. First, many users persist in using weak passwords, often relying on common dictionary words, sequential numbers, or easily guessable patterns. This lax password security provides attackers with a higher chance of gaining unauthorised access to accounts. Second, attackers exploit the fact that many individuals reuse the same password across different online platforms, including WordPress websites. If a compromised password from one platform is successful, attackers can gain access to multiple accounts, amplifying the potential damage.

Common Reasons for Repeated Login Attempts

Several factors can contribute to repeated login attempts on your WordPress website:

1. Inadequate Usernames and Passwords

Weak usernames and passwords act as an open invitation for unauthorised access attempts on your WordPress website. It is a common mistake made by many website owners who opt for generic usernames such as “admin”, “user” or by using their company name. Similarly, using passwords that are easily guessable or commonly used, like “123456” or “password,” significantly weakens your website’s security.

By employing such predictable usernames and passwords, website owners unintentionally provide attackers with a head start in their quest for unauthorised access and significantly weaken their WordPress security. Hackers leverage this weakness, as they know that many users often choose simple or default credentials, allowing them to easily breach the login barrier.

2. Exposure of Login Credentials

The exposure of login credentials poses a severe threat to your WordPress security. If your login credentials have been compromised in a data breach or leaked elsewhere, attackers can attempt to use them to gain unauthorised access to your website. This can occur when users reuse passwords across multiple platforms, as a breach in one service can potentially expose credentials that provide access to other accounts.

Attackers actively search for compromised credentials and employ automated tools or scripts to test these credentials on various websites, including WordPress sites. This method, known as credential stuffing, exploits the fact that users often reuse passwords, banking on the assumption that the compromised credentials will grant them access to other accounts as well.

3. Malware or Infected Devices

Login attempts originating from malware-infected devices pose a significant threat to your WordPress security. Hackers can control a network of compromised computers, commonly referred to as a botnet, to execute coordinated attacks on multiple websites, including yours. These devices may be infected with malware through various means, such as malicious email attachments, compromised websites, or drive-by downloads.

Once a device is infected, it becomes part of the botnet, allowing attackers to utilise the collective resources of multiple compromised devices to launch login attempts. By distributing their efforts across numerous IP addresses, attackers aim to evade detection systems that may block repeated login attempts from a single IP address.

How to protect your WordPress website from login attempts

Protecting your WordPress website from login attempts is crucial for maintaining its security and safeguarding sensitive data. By implementing the following measures, you can fortify your website against unauthorised access and mitigate the risks associated with login attempts:

1. Use Strong Usernames and Passwords

Choose unique and complex usernames that are not easily guessable. Avoid using generic usernames like “admin” or “user.” Additionally, create strong passwords that consist of a combination of uppercase and lowercase letters, numbers, and special characters. Steer clear of common words, predictable phrases, or easily guessable patterns.

2. Implement Two-Factor Authentication (2FA)

Enable two-factor authentication on your WordPress website. With 2FA, users are required to provide an additional verification code, typically sent to their mobile devices, alongside their login credentials. This extra layer of security makes it significantly harder for attackers to gain unauthorised access even if they obtain the correct username and password.

3. Utilise Security Plugins

Install reputable security plugins specifically designed for WordPress. These plugins offer a range of features to enhance your website’s security, such as login attempt monitoring, IP blocking, and malware scanning. Popular security plugins include Wordfence Security, Sucuri Security, and iThemes Security.

4. Limit Login Attempts

Implement a mechanism to limit the number of failed login attempts from a specific IP address. This prevents brute force attacks by temporarily blocking the IP address after a certain number of unsuccessful login attempts. Consider using security plugins that provide this functionality or implement custom code to achieve the same result.

5. Enable CAPTCHA or reCAPTCHA

Integrate CAPTCHA or reCAPTCHA challenges into your WordPress login page. These tools differentiate between human users and automated bots, making it more challenging for attackers to execute brute force attacks. CAPTCHA requires users to complete a visual challenge, while reCAPTCHA utilises advanced algorithms to identify and block suspicious activity.

6. Keep WordPress and Plugins Updated

Regularly update your WordPress core installation, themes, and plugins to the latest versions. Updates often include WordPress security patches that address vulnerabilities and protect against known threats. Enable automatic updates whenever possible or manually check for updates on a frequent basis.

7. Monitor Login Activity

Monitor your website’s login activity using security plugins or monitoring tools. Stay vigilant for any unusual patterns or suspicious login attempts, such as repeated failed logins or login attempts from unfamiliar IP addresses. These indicators can prompt further investigation and allow you to take appropriate action.

8. Secure Your Hosting Environment

Choose a reputable and secure web hosting provider for your WordPress website. Ensure they employ robust security measures, such as firewalls, intrusion detection systems, and regular backups. Additionally, consider using secure protocols like HTTPS to encrypt the data exchanged between your website and visitors.

9. Educate Users about Security Best Practices

Educate all users who have access to your WordPress website about the importance of WordPress security best practices. Emphasise the significance of using strong usernames and passwords, enabling 2FA, and being cautious of suspicious emails or links. Regularly remind users to update their passwords and stay vigilant against potential security threats.

By implementing these measures, you can significantly enhance the security of your WordPress website and protect it from unauthorised login attempts. Safeguarding your website ensures the integrity of your data, preserves your reputation, and instills confidence in your users. Stay proactive, stay informed, and continually assess and update your security measures to stay one step ahead of potential threats.

Conclusion

Repeated login attempts on your WordPress website can be a sign of malicious activity, and it’s crucial to address them promptly to protect your website. By implementing strong usernames and passwords, enabling two-factor authentication, using WordPress security plugins, and following WordPress security best practices, you can significantly enhance the security of your WordPress website and protect it from unauthorised access.
