Why do attackers use such long, random-looking domain names like 0avijs27vivvith1puc9rsnf987ou1rf.site?

Attackers employ long, random-looking domain names generated by Domain Generation Algorithms (DGAs) for several reasons. This strategy helps them evade detection by traditional security filters, creates numerous disposable domains for resilient command and control infrastructure, and makes it harder for users to recognize and remember them as illegitimate, aiding in phishing or spam campaigns by making them appear less distinct.
