Блокировка Смишинга через OpenBLD.net DNS
Рост фишинг активностей занимает первое место в атаках на конечного пользователя/организации.
Среди Фишинг атак есть вид Смишинг "SMiShing" атак - атаки на пользователей через СМС.
Сегодня замечена такая вот рассылка на территории Казахстана, где по сути фиктивная ссылка ведет на фиктивный сайт имитирующий сайт КазПочты... Индикаторы:
- код страны отправителя
- таргет сайт
- факт, что посылка не была заказана
Ссылка ведет на фишинг-страницу поиска посылки, заточенной под post.kz (сайт почтовой службы РК).
Рекомендация: не отвечайте на СМС, при необходимости позвоните в ближайшее почтовое отделение для выяснения деталей, если посылка действительно была заказана и СМС удачно совпало с этим.
🦠 Ресурс отправлен в общие бан листы, залочен в OpenBLD DNS..
✅️️️️️️️ Будьте внимательны, берегите себя вместе OpenBLD.net DNS. Peace ✌️
