Разоблачаем "домашних хакеров"

На одном из "хакерских" каналов увидел статью про взлом bluetooth колонок. Вот копия статьи.
Короткий пересказ статьи:
- Находим девайсы по близости;
- Получаем их MAC адреса;
- Пушим на девайс тысячу запросов ping или connect что-бы колонка отвалилась;
- Радуемся.

Звучит прекрасно, если ты не знаешь как работает bluetooth.

Во-первых, у bluetooth-спикеров есть состояние "discoverable", когда к аудиодевайсу никто не подключен его действительно можно обнаружить сканерами, получить MAC адрес и даже подключиться. Но, если у девайса уже есть активное подключение, то ничего из вышеперечисленного вы сделать не сможете.

Даже зная заранее MAC адрес девайса, и начав отправлять ему запросы, все они будут отклонены.
Единственное, что у вас теоретически может получиться, это имея MAC адрес девайса понять находиться ли он в зоне видимости.
По этому поводу есть хак трехлетней давности на stackoverflow.

Вся статья будет работать только для включенных девайсов без активного подключения, но в таком случае к нему можно просто подключиться.

P.S. Как Вам такой формат публикаций? Если интересно, то могу иногда выпускать подобные "разоблачения".

Telegram Be The Next Best SPAC

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
