With remote work and social media, users have more accounts, platforms and login credentials to remember. As a result, hackers can find and reuse compromised credentials to gain access and perpetrate attacks on a large scale. The threat is fueled by the availability of leaked passwords and hacking tools for sale on the Dark Web. Attackers can scour the Dark Web and underground forums for databases of stolen usernames and passwords, then use automated software to attempt a barrage of login attempts on targeted websites and applications.

Successful logins give attackers access to a user’s account and personal information, as well as other downstream opportunities such as e-commerce fraud or identity theft. For example, video streaming service Netflix fell victim to a credential stuffing attack in 2019, with hackers using breached data and crimeware to steal users’ passwords. Nintendo’s user database also fell prey to a similar attack in 2020.

Stop Credential Stuffing Attacks Online: Prevent Unauthorized Logins

Stop credential stuffing attacks online is that credential stuffing can be stopped with the right cybersecurity measures. These include monitoring for leaked credentials on the Dark Web and other underground forums, enforcing strong password policies with length requirements, requiring unique logins per website or account, and enabling security features such as multi-factor authentication (MFA).

In addition to these preventative strategies, organizations should systematically review fraud case volume over time to identify spikes that may indicate an attack, as well as set clear lines of communication between customer service and information security teams. To protect against unauthorized logins, companies should also deploy devices such as Arkose Labs’ zero trust privileged access management solution (PAM), which screens the devices that connect to the network and blocks credentials from known bad actors, all without disrupting the user experience.…
