What is Credential Stuffing?

Credential stuffing is a type of cyberattack in which automated bots attempt to log in to user accounts using stolen username and password combinations. These credentials are often obtained from previous data breaches and sold or shared on the dark web. Because many users reuse passwords across multiple platforms, even a breach on a single site can put accounts on other services at risk.

These attacks are highly automated, leveraging large lists of credentials and testing them against multiple websites in rapid succession. This makes them extremely efficient and difficult to detect without specialized security measures. According to Have I Been Pwned, credential breaches are widespread, highlighting the importance of proactive protection.

Why Credential Stuffing is Dangerous

Credential stuffing is particularly threatening because it exploits common user habits rather than technical vulnerabilities:

  • Password Reuse: Even platforms that have never been breached are vulnerable if users recycle passwords from other sites.
  • Financial Loss: Attackers can use access to perform fraudulent transactions, transfer funds, or make purchases.
  • Data Theft: Sensitive information such as email addresses, personal details, and business data can be extracted.
  • Trust Erosion: Users lose confidence in platforms that fail to protect their accounts, potentially harming brand reputation.
  • Stealthy Attacks: Bots often operate in ways that mimic normal user behavior, making detection more challenging.

Credential stuffing attacks can occur silently, often going unnoticed until significant damage has been done.

How Prosopo Protects Against Credential Stuffing

Prosopo’s Procaptcha provides advanced bot protection for login forms:

  • Detects Automation: Identifies headless browsers, browser fingerprinting, and automated JavaScript execution used in credential stuffing attacks.
  • Blocks Bots: Ensures that only legitimate human users can attempt to log in, preventing unauthorized access.
  • Privacy-Respecting: Fully GDPR-compliant, ensuring that user data is protected while preventing fraud.
  • Easy Integration: Can be quickly added to existing login flows, providing immediate security benefits without degrading the user experience.

By adding this extra layer of protection, platforms can significantly reduce the risk of account takeover and maintain trust with users.
