I saw some text in Russian recently which talked about phishing attacks. It described one as designed for "mammoths" (мамонтов).
I am interested to learn more about this term. I can guess it means something like "big/desirable target" but I am not sure if that is correct or if there is any nuance missing.
Here is the quote where I saw the term used:
Сегодня в тг получил сообщение, девушка предлагает встретиться в театре, купить билет. После анализа сайта, понял что он рассчитан на "мамонтов"
