Credential Stuffing Creates Cybersecurity Vulnerabilities

Lauren Burnside, writing for MitraTech, says, “Credential stuffing, the stealthy technique fueling a recent explosion of data breaches, is something you want to learn about before you experience it first-hand.”

Credential stuffing takes advantage of a lazy habit computer users fall into, reusing passwords over multiple platforms. The cyber crooks use automated tools to try large sets of user names and passwords stolen from one service to gain unauthorized access to accounts on another service. It doesn’t take much effort and the potential returns are huge. Automation allows hackers to test stolen credentials across many sites simultaneously. It is useful for financial fraud, identity theft, and selling access to compromised accounts on the dark web.

Companies need to move fast to understand the threat that credential stuffing and other automated attacks pose and get security in place to protect themselves and their customers. Poor employee training and lack of attention to best practices, such as frequent password changes, create vulnerabilities. When automation exploits them at scale the impact can be devastating.

Below are a few of the methods of protection the article suggests:

Data Encryption: Sensitive information that is encrypted is indecipherable to unauthorized parties, and significantly mitigates the impact of breaches.

Multi-factor Authentication: A simple form of verification that significantly reduces the likelihood of unauthorized access, even in the event of compromised credentials.

User Awareness and Security Training: Educating users about the significance of creating strong passwords and exercising caution when sharing personal information can help prevent future attacks.

Regular Software Updates: Many updates include security patches that foil cyber threats by addressing vulnerabilities that cybercriminals can easily exploit in outdated software.
