The 10 Weak Passwords That Make You Vulnerable to Remote Desktop Attacks

Microsoft’s Remote Desktop Protocol (RDP) provides a simple and efficient way for users to remotely connect to their computers and servers, making it particularly useful for hybrid work environments. However, RDP also serves as a common target for cybercriminals aiming to exploit vulnerabilities within an organization’s network. While RDP is a powerful tool, using weak passwords can open the door for malicious attacks. Despite the increased awareness of password security, many individuals and companies continue to fall short in securing RDP access, leaving their systems exposed. In this article, we will explore the most common weak passwords used in RDP attacks and provide essential tips on how to safeguard your system.

Weak Passwords in Remote Desktop Attacks

Recent findings from a report by Specops, a password security provider, revealed the top 10 most frequently stolen passwords used to exploit Remote Desktop Protocol (RDP) connections. The analysis, which covered over 1 billion stolen passwords in 2024, highlighted a disturbing trend—many people continue to choose simple, predictable passwords for critical systems.

Here’s a breakdown of the most vulnerable passwords:

123456 – The number one password that is still widely used by many, indicating that people often choose easy-to-remember, sequential numbers.
1234 – A slightly shorter version of the same trend, showing a disregard for basic password security.
Password1 – A variation of the word “password” with a number, still far from secure.
12345 – Another variation of sequential numbers, demonstrating the lack of creativity in choosing a secure password.
P@sswOrd – Some users try to make their passwords more complex by adding a special character, but it’s still easily guessable.
password – Shockingly, “password” is still one of the most common weak passwords.
Password123 – A slight variation on the standard “password” word.
Welcome1 – Often given as a temporary password for new users and left unchanged, making it a target for attackers.
12345678 – A longer version of the sequential number trend.
Aa123456 – Combining uppercase letters with numbers doesn’t create sufficient complexity.

These weak passwords reveal a disturbing lack of attention to security in one of the most vulnerable areas of an organization’s network—RDP connections.

What Should a Secure Password Contain?

Specops’ findings further illustrate that password complexity is a critical factor in securing remote connections. A strong password should include a combination of uppercase letters, lowercase letters, numbers, and special characters. Despite this, less than 8% of passwords involved in RDP attacks contained all four character categories. Moreover, nearly half of the compromised passwords consisted solely of numbers or lowercase letters.

Password length plays a significant role in security as well. Specops’ research indicates that the most common password used in attacks had only eight characters, which is often the minimum length required by many security policies. However, passwords longer than 12 characters become nearly impossible to crack using brute force. Alarmingly, fewer than 2% of the passwords used in RDP attacks had more than 12 characters.

How to Protect Yourself Against RDP Attacks

If your organization or personal accounts rely on RDP connections, it’s crucial to adopt strong security practices. Here are several recommendations to mitigate the risk of attacks:

Enforce Strong Password Policies: Ensure employees create complex passwords or use long passphrases that are over 15 characters. This would have prevented 98% of the password breaches analyzed in the study.
Limit IP Range: Restrict RDP access to a specific range of IP addresses to prevent unauthorized access from external sources.
Block Weak Passwords: Use Active Directory policies to block weak and compromised passwords. Specops also offers a free audit tool to scan for vulnerabilities in Active Directory environments.
Check for Vulnerable Ports: Ensure that RDP ports, especially TCP port 3389, are properly secured, ideally with SSL encryption, and not exposed to the internet.
Implement Multi-Factor Authentication (MFA): Adding an additional layer of security through MFA will make it significantly harder for attackers to gain access, even if they have obtained the password.
Update and Patch: Keep Windows clients and servers updated with the latest security patches to guard against known vulnerabilities.

By following these best practices, individuals and organizations can significantly reduce the risk of falling victim to RDP-based attacks.

What Undercode Says:

Remote Desktop Protocol (RDP) attacks are a growing concern for organizations and individuals who rely on remote access. Cybercriminals continue to exploit weak passwords and exposed RDP ports to infiltrate networks, often without the victim even realizing it until it’s too late. Specops’ findings highlight a critical issue—users still tend to create weak passwords, often based on simple patterns like sequential numbers or variations of the word “password.”

One of the most concerning aspects of this issue is the sheer volume of RDP attacks. Organizations monitoring their RDP connections report thousands of failed login attempts, indicating a massive scale of brute-force attacks. These attackers use automated bots to guess passwords, and the simpler the password, the quicker they succeed. The study reveals a glaring lack of adherence to password best practices, which leaves organizations and their employees highly vulnerable.

It is clear that simple passwords like “123456” or “Password1” are not just bad choices—they are an open invitation for cybercriminals to break into sensitive systems. However, the issue is more than just laziness or ignorance. In many cases, these weak passwords are the result of outdated security policies or systems that allow easy-to-guess credentials, and in some cases, these passwords are used by employees without being enforced to change them.

The importance of enforcing a strict password policy cannot be overstated. Specops’ recommendation to use passphrases with more than 15 characters is an excellent way to ensure passwords are robust enough to resist brute-force attacks. But complexity alone isn’t enough—organizations should also enforce multi-factor authentication (MFA) to provide a second layer of defense.

Moreover, many organizations fail to properly configure their RDP ports, leaving them exposed to the internet. By securing ports and limiting RDP access to trusted IP addresses, organizations can make it much more difficult for hackers to breach their systems. Also, regularly patching systems is a critical defense mechanism against the exploitation of known vulnerabilities.

RDP security requires a proactive and multi-layered approach. Strong password policies, IP restrictions, and regular updates can significantly mitigate the risk, but vigilance remains key. Organizations must continuously monitor their systems for potential threats and adopt a zero-trust approach to security.

Fact Checker Results:

Password Trends: The passwords listed in the report are a known security risk, commonly exploited in brute-force attacks.
Statistics Accuracy: Specops’ data from 2024 aligns with established security research on weak password usage.
Protection Recommendations: Suggested security practices, such as strong password policies and MFA, are universally accepted as best practices in cybersecurity.
