Understanding Credential Stuffing and the Importance of Password Managers Like Keeper Security

In the digital age, cyber security threats are evolving rapidly, with credential stuffing emerging as a significant concern. This cyber-attack method has impacted thousands of individuals, leading to unauthorized access and fraudulent transactions. The Australian Cyber Security Centre defines credential stuffing as an attack where cybercriminals reuse stolen login credentials across multiple platforms. Understanding this threat and employing robust countermeasures, like using Keeper Security, a password manager, is crucial for digital safety.

What is Credential Stuffing?

Credential stuffing occurs when hackers obtain email and password combinations from a data breach and attempt to use these credentials on various websites. Since many people reuse the same login information across multiple platforms, this method often yields unauthorized access to numerous accounts. This attack vector is not just about gaining unauthorized access; it can lead to significant financial loss and identity theft.

Case Studies: The Iconic and Others

Instances like the security breaches at The Iconic, Guzman y Gomez, and Dan Murphy’s illustrate the severity of credential stuffing. Hackers accessed customer accounts, changed login details, and made unauthorized purchases, exploiting stored payment information. The aftermath was not only financial loss but also customer distrust and reputational damage to the businesses involved.

How Credential Stuffing Works

  1. Acquisition of Credentials: Hackers purchase stolen login credentials on the dark web.
  2. Use of Automated Tools: Bots and other automated tools, available on the dark web, are employed to perform the attacks.
  3. Brute Force Method: These tools execute brute force attacks, trying numerous username and password combinations on different websites.

Detecting a Breach

Often, the first sign of a credential stuffing attack is an unauthorized transaction in a bank account. Businesses may detect these attacks through unusual patterns in transactions. Additionally, users might receive unexpected order confirmations or find themselves unable to access their accounts.

Role of Keeper Security in Preventing Credential Stuffing

Keeper Security specializes in scanning password hashes and comparing them against known compromised passwords on the dark web. This proactive approach helps in identifying and securing breached accounts before significant damage occurs.

Personal Protective Measures

  1. Unique Passwords: Use a distinct, strong password for each online account. A mix of upper and lower-case letters, numbers, and symbols, forming a 24-character passphrase, is recommended.
  2. Temporary Credit Cards: Utilize temporary credit cards with low limits for online purchases, and avoid saving payment details on websites.
  3. Multi-Factor Authentication (MFA): Implement MFA for an added layer of security. It requires additional verification beyond just the password, such as a text message code or an authenticator app code.


Credential stuffing represents a sophisticated and prevalent threat in the realm of cyber security. It exploits common user behaviors like password reuse across multiple platforms. The importance of adopting robust security measures, both personally and professionally, cannot be overstated. Utilizing tools like Keeper Security, practicing strong, unique password hygiene, and employing multi-factor authentication are vital steps in safeguarding against credential stuffing attacks. By staying vigilant and embracing these security practices, individuals and businesses can significantly reduce their vulnerability to these increasingly common cyber threats.
