Подозрительный трафик на сайте

Ребята подскажите,

Закрытый корпоративный сайт, без регистрации, доступ только после авторизации.

в логах показывает такой трафик, судя по всему это боты поисковых систем, но откуда эти папки yoni6f у меня их в помине нет

Буду благодарен за подсказки (сканил антивирусом — проблем нет)
