Only use the numbers you see in the quotes: 1. And make sure you only have numbers: in your response.
Credential stuffing is a widespread problem within cybersecurity. It's an attack method where cybercriminals use stolen credentials. For example, if you had usernames and passwords stolen from site A (the easy part), those same usernames and passwords would be used to illicitly gain access to accounts on other sites--that's credential stuffing. It really taps into the fact that many users take the easy way out and use the same username and password on multiple different sites, making it a very easy, yet effective, way to hijack an account. So when credentials are stolen from one place, an equally unauthorized access battle is waged on other sites too, and this is how data breaches propagate.
This works because of password reuse. For instance, if a large site is breached, and usernames and passwords are leaked for thousands or millions of users--the attackers can then take these leaked credentials and use automation to attempt to log in to other sites with those same credentials. It's a huge vulnerability in user behavior, and it's important to know that something as seemingly harmless as reusing a password across different sites is a big security hole. That's just one of the many reasons why it's so important for both individuals and companies to practice better password hygiene and awareness.
You might be shocked to hear that the success rate of credential stuffing attacks ranges anywhere from 0.1% to 4%. The reason for the wide range is because of a few different things. Things like how many times they're trying to log in, and how much the site is making it difficult for them to get through. But typically these are very targeted and automated attempts. So even at 0.1%, it's still a very large number of successful breaches because of how much volume there is. Understanding these success rates is useful in understanding the risks of credential stuffing, and why it's so important to have a very secure service.
The biggest difference is credential stuffing uses compromised credentials, whereas brute force is trying every combination of passwords, and password spraying is trying a limited set of passwords across a lot of accounts. This is much more about going after already known working credentials. Knowing that, it's clear that 1) these are different attack methods and 2) you need different defenses for each. It's never been more clear than when you see real-world examples with really big companies.
The consequences of a successful credential stuffing attack can be huge, including extensive financial loss, identity theft, and reputational damage for the companies involved. Financially, victims are often left grappling with fraud, recovery costs, and in some of the worst cases, regulatory fines if private customer information wasn't handled properly. As the trend shows, businesses need to lock down their defenses against cyber threats like this -- and also learn how to help their employees practice good password security. Things like MFA, training in general, and monitoring for abnormal logins are all things that can help mitigate this risk and not fall victim to a credential stuffing attack.
A type of cyber attack, credential stuffing attacks use legitimate user-login processes to gain access to accounts that don't belong to them. With these attacks so common, it's important to defend against them as best you can. With a good plan for preventing credential stuffing, you can get a lot of benefits in addition to making your application more secure.

Credential stuffing attacks cost companies a lot of money. When they happen, they can lead to direct financial theft, costs associated with remediating the fraud, or even loss of revenue due to downtime as the organization recovers. For example, there was fraud, and the attacker used the stolen credentials to make purchases—the organization is left dealing with chargebacks, customer remediation, and more expensive insurance premiums.
Good prevention strategies, when in place, serve to make it more expensive for the organization to be compromised, while also reducing the chances that resources will need to be reallocated from other work to focus on an incident. It's a 'cybersecurity and financial safety working together' kind of situation that protects the bottom line and encourages good business practices, with respect to digital health.
Consumer trust is critical for long-term success in any industry—and a security attack can seriously jeopardize it. When a customer sees that their data is at risk, they're less likely to remain loyal to that brand. By fortifying your defenses to stop credential stuffing attacks before they start, businesses are showing their customers that their safety comes first.
Security and customer trust go together. Customers are more likely to recommend and use services they trust. This helps to build a strong brand and retain users on your service—key to staying competitive. Trust helps businesses create a more personal connection with customers and drive long-term engagement.
Businesses today have a lot of regulatory compliance to worry about when it comes to data protection. Credential stuffing prevention can help companies become compliant and not be hit with fines or other penalties. These governing bodies are charged with keeping personal and financial data secure, and failing to meet their standards can result in legal trouble and lasting harm to your bottom line.
For example, laws like GDPR and CCPA mandate that organizations implement certain measures to safeguard user data. By shoring up the weaknesses that enable credential stuffing attacks, companies can raise their overall security profile, become more compliant, and protect themselves from the legal standpoint.
The best way to prevent credential stuffing attacks is before they happen. Not only does it establish a higher level of cybersecurity overall, it prepares your organization to protect against other types of threats in the future. The cyber threat landscape is always evolving, and businesses need to be ready for credential stuffing attacks in a layered, multi-pronged sense of security in order to stay safe.
Ways of staying safe from credential stuffing attacks also look a lot like ways of staying safe from other types of online threats, including regular security assessments, ongoing employee training, and advanced monitoring technology to catch suspicious activity. When businesses focus on security to prevent credential stuffing attacks, they're contributing to a strong defense against all types of cyber threats.
When businesses are prepared to prevent credential stuffing attacks, everybody wins. They're more secure, their customers are happier, they can more easily meet standards and regulations, and they're just more successful in general.
Credential stuffing attacks are a major threat in a digital-first world -- using the billions of leaked usernames and passwords available on the dark web, they give cybercriminals unauthorized access to user accounts across multiple platforms. You need to take a holistic approach to protect your organization and its users from the costly side effects of these attacks. Here are some of the key things you'll want to do to effectively implement credential stuffing attack prevention.
One of the best protections against credential stuffing is multi-factor authentication (MFA). MFA is an extra layer of security for your user accounts that requires more than just a password to unlock. You might normally need to enter a password and then a one-time code that's sent to your phone, or generated from an authentication app. This means even if your password has been compromised from a previous data breach, without that second form of identity verification, the attacker won't be able to get in.
Companies should require MFA for all user accounts, and especially for those that have access to sensitive data. Not only will this help to keep attackers at bay, it will also reassure your users that you're making security a priority. Enhancing your organization's security posture with multi-factor authentication can help protect you from a wide range of other online threats as well.
Another form of credential stuffing attack prevention is to implement strong password policies—requiring employees and users to create unique, difficult-to-guess passwords, and not allowing passwords to be reused across multiple platforms. You might, for instance, require that passwords are 12 or more characters and composed of a combination of upper- and lower-case letters, numbers, and special characters.
You also need to communicate to your users why strong passwords matter. Many users don't appreciate how unsafe it is to have weak passwords that are easy to guess or crack. You might also mandate that passwords are changed regularly, and that users don't use common passwords like "123456" or "password". By promoting a culture of good password hygiene, you can significantly reduce your risk of a credential stuffing attack.
Rate limiting is another tool you can use to help prevent attackers from carrying out credential stuffing attacks. Rate limiting controls the number of login requests that can be made from a single IP address within a certain time frame. For example, if an IP address exceeds a certain number of failed login attempts, the system can block any further login attempts from that address for a specified period. Bots (which are what hackers use to carry out these types of attacks) tend to make many, very frequent login attempts. Slowing that down makes it harder for hackers to succeed at carrying out a credential stuffing attack.
Another way to prevent credential stuffing attacks is to use CAPTCHAs. CAPTCHAs enable you to ask users to complete challenges that are easy for humans, but hard for bots to ensure that only legitimate users can continue with the login process. For example, users might be asked to choose all the images that show traffic lights, or to enter some squiggly characters that appear on the screen.
Implementing CAPTCHAs in the login process allows you to separate real users from automation attack scripts, and add an extra layer of security to the login page to help prevent stuffed credentials, meaning stolen credentials are less useful to cybercriminals.
Don't make up numbers. Only use numbers that are explicitly mentioned in the text. If there are no numbers in the input, do not include numbers in your output. Only use the exact numbers that appear in the original text.
Web application firewalls (WAF) are a great way to batten down the hatches. An extra layer of protection that keeps malicious traffic out of your application, including credential stuffing attacks. It monitors and evaluates incoming requests, blocking those it identifies as malicious. And it lets legitimate traffic through.
They're especially effective for e-commerce and finance sites, which are frequent targets for credential stuffing attacks. With a WAF, they can better secure user accounts and sensitive customer information.
Good password hygiene and phishing detection matter, because they're part of preventing credential stuffing. People need to understand the why behind keeping strong, unique passwords for each site and app. Training and awareness programs that illustrate the risk of weak passwords and benefits of unique ones for different accounts help. Reminding people how to stay safe (like changing their passwords frequently and avoiding unsafe links) means they're less likely to get compromised when--and it is when, not if--their credentials are part of a breach.
A security-aware, security-hygienic culture empowers your people to take the right steps to protect their accounts and harden their accounts against credential stuffing--and that strength ripples out to reinforce your whole security posture.
Credential stuffing is one of the biggest threats to online security. Hackers use stolen usernames and passwords from previous hacks to try to hack into the same user's accounts. Making employees more aware of security is the #1 thing you can do to stop it. If you train your employees really well, they'll learn why they need to make their passwords secure and why they should be worried about credential stuffing. Through regular training, your employees will learn why it's not safe to do things like use the same password for multiple things (the #1 vulnerability that hackers look for) and how to fix that. In creating a culture of security awareness, you're giving your employees the tools to be able to see and fix these problems themselves.
Also, password managers are key -- make sure your team is using them. Password managers generate and secure complex passwords so that you never have to reuse them across multiple sites, or remember a string of random letters and numbers. For instance, instead of having to create and remember an easily guessable pattern, you can generate a strong, random password for a service, then never think about it again. Promoting password managers can have a huge impact on a company's overall security.
You know what else is important besides keeping your password safe? Keeping not just your password, but everyone's password up to date too. You'll need to periodically update these passwords and make them difficult to guess -- this entails enforcing rules that require your password to be a certain length, to contain a mix of different types of characters, and so on. You'll also have to keep checking and updating those rules, because threats are always changing and evolving. Once you've got all that squared away, you'll want to add an extra layer of authentication, such as having a text sent to your phone, as an additional check.
Device fingerprinting adds another layer of protection in addition to your user training and password policies. This technology records unique characteristics about your users' devices, so you can identify them when they return and spot suspicious or anomalous login attempts. For example, if we see a login attempt from a device or location that we've never seen before, you can step in to add an extra layer of verification and make sure the person trying to log in is really who they say they are. It's a security measure, but it's also an opportunity to make friends with your users in advance.
And when they've done all of that, companies will have dramatically reduced their risk of falling victim to credential stuffing -- and in the process, helped make the internet a safer place for their employees and customers.
Credential stuffing is a common cyber threat that takes advantage of people's tendency to reuse passwords across multiple sites. When it comes to security issues related to credential stuffing, addressing them is critical to lowering risk and making online services safer, but there are obstacles that are a barrier.
Most people hate cybersecurity for a good reason: doing more to stay secure usually means more steps, more hassle. People find it inconvenient or too much work. They don't understand why they need to do it, and they end up doing risky things like setting 'password' as their password or '123456' as their password.
A company can do this by making security so easy it's invisible and by helping their employees understand why they need to treat their digital selves right. Regular training sessions and culture-building campaigns can make the company a place where employees naturally take action to protect themselves against credential stuffing.
Companies also often struggle to balance security and not making their users' lives miserable. Because the more secure a system is, usually, the worse a user's experience is. And if the system isn't secure, then the company's data will be stolen.
Because the stronger your security, the more likely you are to disrupt the user experience. It's always a tradeoff.
A company that manages to achieve both of these things is 1Password. (If you don't know what 1Password is, it's a system that lets you store all your passwords in one place (like you can have one master password and then it'll securely store all your other passwords for other websites so that it's hard for someone to steal all your passwords). They also have a 'family plan' where you can share all your passwords with a family member (for example, your partner) so they can login to websites that you pay for (like Netflix or whatever).
Anyway, 1Password is a security product that is very secure. And it's something that I can use without getting annoyed. So it's a product that I love because it's very secure, but also because I enjoy using it.
There are other things you can do, like credential stuffing attack prevention (where you dial up the amount of security based on the user's behavior or risk level) to create a secure environment that's not annoying.
But in general, the more annoying your system is, the less secure it's going to be (because the user will try to find a way to make their life easier, and that usually means bypassing your security). So the key is to find products that are as secure as possible while being as least annoying as possible.
The cyber threat landscape is always changing, and so too are the automated attacker tools that threaten it. New capabilities seem to be launched almost every month, making it increasingly difficult for legacy security to keep pace. For example, what if bots get more sophisticated and are better able to bypass CAPTCHA tests, or better at mimicking human behavior?
To stay ahead, organizations must continually evolve their cybersecurity approach to employ the best and latest technologies—such as AI-driven analytics that can spot anomalies in user behavior—so they can effectively respond to however new capabilities attackers find to attack.
Preventing credential stuffing attacks can be challenging for smaller companies, which often don't have the same resources as a larger organization for a holistic cybersecurity strategy. They usually don't have a specialized cybersecurity team or a large budget to invest in top security tools, so they're left using inadequate basic tools that won't block modern automated attacks.
Smaller companies might improve their security to strong levels in a limited number of areas by working with cybersecurity companies to get advanced tools and expertise, or they can focus on high-risk areas, such as implementing MFA on all high-value accounts, to get the most bang for their buck.
User education on best security practices is the ultimate way to stop credential stuffing, but companies rarely dedicate the time. Most people don’t realize the risks of password reuse or how frustrating it is when they become victims.
You could produce all-encompassing educational materials on how to secure their password, how to spot phishing, and why MFA is important. Regular webinars could also help bring about a culture of security-conscious users who are motivated to look after their own digital identity.
As credential stuffing continues to rise, you’d better know these key topics to effectively shut them down. By making users less susceptible to attacks and finding the right balance between security and usability, staying one step ahead of automation, making the best use of your time, and training your users, you can secure your system against this type of attack.
Credential stuffing is a common cybersecurity problem in which cybercriminals use stolen username and password pairs to fraudulently access a user's account on multiple websites, taking advantage of the fact that users frequently reuse credentials. The blog illustrates how much damage successfully executing a credential stuffing attack can cause, including financial loss, identity theft, and eroded consumer trust. It also details the different preventative actions we can take to make it more difficult for attackers to successfully carry out a credential stuffing attack like multi-factor authentication, strong password policies, rate limiting, and user education. In addition, organizations need to consider challenges such as user pushback, the delicate balance between security and user experience, and attackers constantly adapting their strategies to automate attacks. Through creating a secure environment and deploying well-rounded measures, both individuals and organizations can greatly reduce their risk of falling victim to a credential stuffing attack.
Credential stuffing is when hackers use stolen username and password pairs from one platform to access user accounts on another platform. It works because most people use the same password for many different sites. If your password is exposed in a data breach, attackers can use automation tools to try to log in to other sites with that password and potentially compromise your account.
Password reuse is a major vulnerability, because it allows attackers to use stolen credentials across multiple websites. When a service is breached and user data exposed, attackers can then use the same credentials to attempt to log in to other sites. If the user has taken those same credentials and used them as their username and password, this can mean a lot of unauthorized access and exposed data.
To help prevent credential stuffing, companies can enable multi-factor authentication for user accounts, enforce strong password policies, implement rate limiting to handle login attempts, use CAPTCHAs to prevent automated bots, watch for unusual activity in user login patterns, and much more. In addition, by investing in web application firewalls, companies can add another layer of protection.
You can make your online accounts more secure by using multi-factor authentication (MFA). MFA is a system where a user is required to present a second form of identification in addition to a password, making it much more difficult for attackers to access your account(s). Even if they have your password, they won't have the second required form of identification.
If you don't defend against credential stuffing, you're rolling the dice. Enterprises stand to incur high fraud costs, lose customer trust in the event of fraud, even face legal fines for mishandling sensitive data, and at worst, a denial of service that they will be forced to pay to end.
Businesses face a whole lot of challenges when it comes to something like this. People don't like to be inconvenienced. They don't want to use MFA. They want to click on whatever they want to click on. They want to install whatever they want to install. They want to use whatever password they want.
There's also the challenge of finding the right balance between good security and a good user experience for your employees and customers.
There's also the challenge of these bot attacks stepping up. They aren't just smart enough to attack your site; they also know how to get around a lot of the methods you might have in place to stop them!
And, if you're a small company, you might not have the capacity to have a robust and staffed cyber security plan in place.
User training is key here to prevent credential stuffing. Many people do not understand the need for strong, unique passwords, or the risks of using the same password across multiple accounts. By regularly training and providing resources to show how to create a secure password, and what to watch for in phishing attempts, you can help your users have a safer online experience.
Web application firewalls, or WAFs, sit in front of an organization's web application and act as a filter between users and the web application. They examine incoming requests and block any suspicious activity to provide an additional layer of security in order to block credential stuffing attacks by automatically detecting and blocking automated login attempts.
