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

The Growing Threat of Remote Desktop Attacks

In a recent report from Specops, a password security provider, the most commonly stolen passwords used to exploit RDP connections were revealed. This research analyzed over 1 billion stolen passwords from cybercriminals in 2024, highlighting disturbing trends in password practices. Despite the availability of security tools and protocols, many people still rely on easily guessable passwords for critical systems like RDP.

The report shows that organizations monitoring their RDP servers are seeing hundreds, if not thousands, of failed login attempts, often from hackers, bots, and ransomware groups. Once an RDP port is exposed, attackers can use brute-force methods to test various username and password combinations to breach the system. The simpler the password, the easier it is for attackers to gain entry.

Top 10 Weak Passwords That Put Your RDP Connection at Risk:

Unsurprisingly, some of the weakest and most commonly used passwords are simple, numeric, or basic variations of the word “password.” The most prevalent password found in the data was “123456,” closely followed by “1234.” These kinds of passwords are often referred to as “keyboard walks” because they are created by typing adjacent keys on the keyboard. Other common offenders include “Password1,” “12345,” and “P@sswOrd,” a weak password that attempts to meet basic password complexity requirements by adding a special character, yet remains easy to guess.

The list of most stolen passwords also includes “password,” “Password123,” “Welcome1,” “12345678,” and “Aa123456.” Some of these, like “Welcome1,” may be used as temporary passwords by organizations but never updated, leading to significant vulnerabilities.

What Makes a Secure Password?

To safeguard your RDP connections,

Moreover, the length of a password is just as crucial as its complexity. Specops found that 92% of RDP port attacks could have been stopped with a relatively simple, short but complex password. Passwords with at least 15 characters are nearly impossible to crack using brute-force methods, and fewer than 2% of passwords involved in RDP attacks had more than 12 characters.

How to Protect Your RDP Connection

Given the risks associated with weak passwords, how can individuals and organizations better protect themselves? Specops offers several strategies:

Enforce Strong Password Policies: Organizations should require employees to use complex, lengthy passwords or passphrases. Passwords longer than 15 characters would have blocked 98% of the attacks analyzed in the report.
Limit IP Range for RDP Connections: Restricting which IP addresses can access RDP services reduces the chances of unauthorized access.
Block Weak Passwords with Active Directory Policies: Use Active Directory to prevent the use of weak and compromised passwords. Specops even offers a free audit tool to help identify vulnerabilities in your system.
Ensure Proper Port Configuration: Misconfigured RDP ports can make systems vulnerable to attack. Ensure that RDP ports use secure SSL connections and are not exposed to the internet.
Implement Multi-Factor Authentication (MFA): Adding MFA to RDP connections ensures that even if a password is breached, the attacker cannot access the system without the second layer of authentication.
Keep Software Up to Date: Regularly patching Windows clients and servers helps protect against critical vulnerabilities that could be exploited by attackers.

What Undercode Says

This report underscores a fundamental issue with many organizations today: they fail to apply basic cybersecurity practices like using strong passwords for critical systems such as RDP. In fact, many organizations are still operating under the false belief that passwords such as “123456” or “Welcome1” are sufficient. These weak passwords expose systems to a wide range of threats, from individual hackers to large, organized cybercrime groups.

It’s not just about the complexity of the password but also about user behavior. For instance, many weak passwords are generated as part of a simple “keyboard walk” pattern, which makes them predictable. Using complex, random passwords is only part of the solution. Organizations need to instill a cybersecurity culture where employees are educated on the importance of robust password management and the risks of using weak or repeated passwords.

What’s alarming is the tendency for organizations to stick with default or temporary passwords that don’t get changed. This negligence creates opportunities for hackers to exploit exposed RDP ports and gain unauthorized access to corporate networks. It’s critical that businesses audit their systems regularly and implement stronger policies to prevent these kinds of vulnerabilities from being exploited.

Moreover, organizations should be aware that a password is not a silver bullet for security. The implementation of multi-factor authentication, routine system updates, and limiting the exposure of critical ports are all part of a layered security approach that can significantly enhance the resilience of an organization’s IT infrastructure.

The bottom line is this: weak passwords are one of the easiest ways for attackers to breach your systems. While it’s easy to get caught up in the complexity of advanced cybersecurity measures, something as simple as enforcing strong password policies can make a world of difference in reducing your organization’s risk.

Fact Checker Results

Upon reviewing the report from Specops, the findings confirm that weak and reused passwords are indeed a significant threat to RDP security. The data aligns with long-standing cybersecurity best practices: complexity, length, and diversity in passwords are key to thwarting brute-force attacks. Organizations must address both the technical and human factors contributing to weak password use.
