salasanaluettelohyökkäys

Salasanaluettelohyökkäys, also known as a dictionary attack, is a type of brute-force cyberattack used to gain unauthorized access to user accounts. This attack method involves systematically trying a predefined list of common passwords and words, often referred to as a "dictionary," against a login system. Unlike a purely random brute-force attack, a dictionary attack is more efficient as it focuses on passwords that are statistically likely to be used.

The effectiveness of a salasanaluettelohyökkäys relies heavily on the quality and comprehensiveness of the password list. Attackers often compile these lists from various sources, including leaked password databases, common password compilations, and even by using personal information related to the target, such as names, birth dates, or common phrases. The attack is automated, using software to quickly try each word from the list against the username's password field.

To mitigate the risk of salasanaluettelohyökkäys, several security measures can be implemented. These include enforcing strong password policies that encourage the use of complex and unique passwords, implementing account lockout mechanisms after a certain number of failed login attempts, and employing multi-factor authentication, which requires users to provide more than one form of verification. Regular security audits and monitoring for suspicious login activity can also help detect and prevent such attacks.
