Открытые порты: невидимая угроза, которая может стоить миллионы

🔎 Публикуем тезисы из доклада Максима Казенкова, эксперта направления DevOps.

💵 В 2019 Capital One потерял данные 100+ млн клиентов из-за одного открытого порта. Обошли firewall → попали в базу. Штрафы, компенсации, удар по репутации — на десятки миллионов долларов.

Почему это важно?
Каждый открытый порт = потенциальная дыра в системе. Если не заметить или настроить неправильно — злоумышленник это сделает за вас.

Что с этим делать?
Регулярно сканировать периметр. Но тут есть свои нюансы:

- Nmap — точный, но слишком медленный при масштабном сканировании.
- Masscan — очень быстрый, но часто выдаёт ложные срабатывания и не подходит для глубокого анализа.
- Коммерческие сканеры — как стрелять из пушки по воробьям: тяжёлые, дорогие и зачастую избыточные. Их настраивать — отдельный квест, а стоят как крыло от Боинга. Да и заточены они под всё подряд: уязвимости, инфраструктура, политика, а не просто периметр и порты.

➡️Так родился NMon, который объединяет скорость Masscan и точность Nmap, поддерживая распределенное сканирование.

Это позволяет:

🔹 анализировать периметр в реальном времени.

🔹 гибко настраивать параметры сканирования.

🔹 встраивать в системы безопасности.

🤖 Впереди — ML для автоматического распознавания административных панелей и анализа изменений в инфраструктуре.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
