Distributed login attacks threaten banking verification
Question asked:
“Distributed automated login attempts can overwhelm identity verification servers and the database connection pool, constituting a realistic threat to online banking applications.”
Summary
Automated, distributed login attacks such as credential stuffing and password spraying are documented to generate massive volumes of login attempts that can saturate authentication services and exhaust database connection pools. This overload is recognized as a realistic and significant threat to online banking applications, requiring mitigation measures like rate limiting, MFA, and bot detection.

A 'Failed Login Attempt' refers to the unsuccessful login efforts made by a user, which are tracked by a system to enhance security. After a specified number of failed attempts, the user's account is automatically locked to prevent unauthorized access.

What you're currently experiencing might be hackers using automated scripts to try and obtain your password. They can do this merely with your account name, and it has nothing to do with whether you've activated a mobile authenticator, which adds an extra layer of protection for you. Please understand that hacking attempts occur constantly worldwide, and we can only enhance the security of our accounts. You can temporarily revoke the login permissions for your current account, which can effectively deter intruders who already know your account name.

These techniques also require more work on the attacker’s part, which gives you more opportunity to detect the attack and maybe even identify the attacker. Although brute-force attacks are difficult to stop completely, they are easy to detect ...

If login attempts are not properly monitored, limited, and protected by layered controls, automated brute-force attacks can occur at scale. In a traditional brute-force scenario, attackers repeatedly attempt password combinations until one succeeds.

The distributed nature of large botnets enables threat actors to conduct high-volume password spraying attacks, where each compromised device plays a role in testing stolen credentials. This strategy minimizes detection risk and challenges traditional security controls due to the sheer volume of login attempts...
