Safeguarding Your Business: 9 Effective Strategies Against Credential Stuffing Threats

Did you know that in 2019, the login details of approximately 4 million Canva users were pilfered, decrypted, and subsequently exposed online? This incident was a result of a credential stuffing attack.

Before delving further, let’s clarify what a credential stuffing attack entails.

Understanding Credential Stuffing Attacks

A credential stuffing attack is a method employed by cybercriminals to exploit vast databases containing user credentials. These malevolent actors utilize an automated system to input previously compromised username and password combinations into the login fields of various websites, attempting to gain unauthorized access to user accounts.

This approach is gaining traction, particularly among novice hackers who have easy access to tools enabling them to breach numerous online services and websites. Shockingly, research indicates that companies face an average of 12.7 credential stuffing attacks per month, resulting in staggering losses amounting to $6 million.

Given the substantial risks involved, businesses must take proactive measures to shield themselves from credential stuffing attacks.

9 Best Practices for Protecting Your Business Against Credential Stuffing

  1. Implement Multi-Factor Authentication (MFA) Utilize MFA during login processes to enhance security. By requiring an additional verification factor beyond usernames and passwords, such as one-time passwords (OTP), the likelihood of successful attacks is significantly reduced. This is crucial since 61% of users employ the same password across multiple services.
  2. Avoid Using Email Addresses as Usernames Discourage the use of email addresses as usernames, as this makes it easier for cybercriminals to exploit reused credentials. Encourage users to adopt distinct usernames and email addresses to minimize the risk of compromising multiple accounts.
  3. Focus on Threshold Alerting for Failed Login Attempts Employ threshold alerting mechanisms to detect and respond to a series of failed login attempts. Automated messages and custom scripts can be used to disable login functionality temporarily, preventing unauthorized access.
  4. Enforce Strong Password and Authentication Policies Promote the use of strong, unique passwords and password managers. Set limits on the number of failed login attempts, requiring users to reset their passwords regularly. This helps mitigate the risk of compromised credentials, as 81% of data breaches stem from weak passwords.
  5. Adopt Passwordless Authentication Explore innovative passwordless authentication methods, leveraging devices, alternate accounts, or biometrics. This not only enhances security but also alleviates the burden of remembering complex passwords for users.
  6. Utilize Web Application Firewalls (WAF) Implement WAFs to identify abnormal traffic patterns indicative of credential stuffing attempts. WAFs play a crucial role in preventing data breaches caused by web attacks.
  7. Implement Credential Hashing Safeguard passwords by employing credential hashing, scrambling user passwords before storage. Even if cybercriminals gain access to hashed passwords, the complexity of hashing limits their usability.
  8. Use IP Blacklisting Monitor and blacklist IP addresses associated with suspicious login attempts. Although susceptible to IP spoofing, comprehensive IP blacklisting remains a valuable tool in preventing unauthorized access.
  9. Block Headless Browsers Identify and block headless browsers, often used by cybercriminals for illicit activities. This involves controlling or blocking such browsers through automated scripts or command-line interfaces.

Real-Life Examples of Credential Stuffing Attacks

Credential stuffing attacks have impacted various sectors, leading to notable breaches:

  • The North Face (2020): Experienced a massive attack compromising customer information.
  • HSBC (2018): Faced a major credential stuffing attack affecting thousands of customers.
  • DailyMotion (2019): Battled a large-scale credential stuffing assault, providing personalized support to affected customers.
  • Dunkin Donuts: Endured two credential stuffing attacks within three months, prompting proactive measures to secure customer details.


While there is no foolproof solution against credential stuffing attacks, implementing these nine strategies adds an extra layer of security. It’s essential for businesses, regardless of size, to partner with reputable security experts to safeguard customer credentials diligently. Remember, protecting your business means safeguarding your customers and their sensitive information.
