2 measurements taken within a single day. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 740–742 and does not start at zero.

Engagement

20 posts held, back to 26 March 2019the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 5 December 2021. An engagement rate over an empty window would be a number about nothing.

Lifetime counters from Telegram’s own channel header, read 6 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

Хотите научится искать уязвимости в V8, но не знаете с чего начать? Не так давно вышла серия занимательных постов от seal9055, которые введут вас в курс дела! Начинать рекомендую с https://seal9055.com/blog/?p=browser_architecture&d=browser

кстати, я на днях ресерч опубликовал - не совсем по сабжу но тоже про браузеры https://fingerprintjs.com/blog/external-protocol-flooding/ сорсы + демка https://github.com/fingerprintjs/external-protocol-flooding

Забавный ресерч. Будь я хакером, я бы рассматривал хром как точку входа для какого-нибудь pwn2own. ELECTRIC CHROME - CVE-2020-6418 on Tesla Model 3 https://leethax0.rs/2021/04/ElectricChrome

2020 потрясающий год. Помимо всего прочего, в Chrome можно подделать заголовок Referer, чего не было более десяти лет (раньше с помощью Flash можно было подменить этот заголовок). PoC был выложен несколько дней назад и совершенно тривиальный: <base href="https://www.google.com/"> <style> @import 'https://CSRF.vulnerable.example/'; </style> Запрос к сайту уйдет с заголовком Referer: https://www.google.com/ К сч

По всей видимости, мы скоро можем попращаться с Reverse Tabnabbing. Начиная с версии Chrome 88, браузер по-умолчанию будет считать ссылки с target=_blank как noopener и таким образом присоединится к Safari и Firefox, которые уже, к вашему сведению, так делают. В двух словах об атаке. Если кто не знает, в HTML-теге <a>, предназначенном для создания ссылок, можно установить аттрибут target со значением _blank и тогда

А в хроме недавно можно было обойти CSP, используя гонку в JS. https://www.perimeterx.com/tech-blog/2020/csp-bypass-vuln-disclosure/

Забавный, но действенный шаг. Многие сайты собирают информацию о браузере и окружении (WebRTC, Canvas и вот это вот все, например, с помощью популярной fingerprintjs). Но браузер Brave решил генерить фингерпринты на лету и из коробки. https://brave.com/whats-brave-done-for-my-privacy-lately-episode3/

Еще одна атака с использованием CSS была в FF. Интересно то, что благодаря HTTP/2 эксплойт срабатывает очень быстро, без необходимости держать пользователя на странице. https://research.securitum.com/css-data-exfiltration-in-firefox-via-single-injection-point/

Showing the 12 most recent of 20 posts we hold for @br0wsec. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Forward network

Republishes

Channels on the register whose posts this channel has forwarded.

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
