3 measurements spanning 11 days, net -3. 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 475–478 and does not start at zero.

Engagement
16 posts held, back to 25 April 2024 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of 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 16 posts for this entry, the most recent from 19 March 2025. An engagement rate over an empty window would be a number about nothing.
Reaction mix
133 reactions across 13 posts, in 11 distinct kinds. The most used accounts for 42.9% of them.

Custom emoji. 2 of the rows above are Telegram custom emoji, which the public preview renders as an element carrying only a numeric id — no character, and no image we can reach. The id is printed as-is rather than substituted with a look-alike glyph, because a stand-in would be our invention showing where a measurement should be. The counts beside them are Telegram’s.
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 15 of the 16 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 133 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 16 most recent posts we hold, published 25 April 2024 to 19 March 2025, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

A paid reaction is a reader spending Telegram Stars — bought with money — on a post by @knckn. Telegram publishes the count on the public post preview alongside ordinary reactions, and this register reads it there. It is the only figure on this site that measures money moving rather than attention.
Stars are not reactions, and the two are never added. They are rendered in the same strip on Telegram and counted in the same shape, but one is a tap and the other is a purchase. The reaction totals and the engagement rate elsewhere on this page exclude every figure in this section, and no rate here is computed against a reaction count.
This is not revenue, and we publish no currency figure. What a Star costs a reader and what it pays a channel are different numbers, Telegram takes a share we cannot observe, and the terms have changed. Converting a Star count into money would be an estimate dressed as a measurement, so the count is where we stop.
Counted over the 16 most recent posts we hold for this entry, published 25 April 2024 to 19 March 2025. Star counts above 1,000 reach us in Telegram’s short form and carry the same three-significant-figure rounding as everything else on this page.
Давно не выходили на связь — исправляемся! 💌
Мы прокачали главный экран сервиса, и теперь всё стало ещё удобнее! 🎉На главном экране вы найдёте рекомендованные наборы проверок, которые помогут убедиться, что ваши СЗИ надёжно защищают почту. Запустить набор проще простого — нажимайте на кнопку запуска и выбирайте, с какого адреса нам отправить вам семплы.
Но и это ещё не всё! Теперь отчёт легко заполнить, а нужное пи…
Из других обновлений:
1. Теперь появились "градации" атак, от скрипт-кидди до APT группировок. Можете проверить, насколько почта уязвима для каждого типа хакеров.
2. Появились первые семплы ВПО для Linux. Мы получаем все больше запросов на добавление Linux, потому что постепенно в инфраструктурах клиентов появляются сегменты с рабочими машинами на отечественных ОС.
3. Документация по сервису доступна здесь
И последн…
За время с последнего сообщения в Knockin появилось много всего нового, но самое важное это доставка ВПО с помощью ссылок. Почему это важно?
1. По нашей статистике ссылки примерно так же популярны, как вложения (43% против 56%)
2. Средства защиты почты в целом не всегда в принципе умеют определять контент ссылок и отправлять его на анализ
3. Но если и умеют, то плохо умеют работать например с Javascript или HTML-Smug…
Летом в Positive Research вышла наша статья совместно с Константином Полишиным (PT SWARM), который на текущий момент руководит командой хакеров и сам занимается red team проектами и в т.ч. социальной инженерией.
В статье описаны текущие техники для социалки, что используют и как это работает. Важная часть каждой техники — описание того, почему каждый из семплов успешно остается незамеченным для СЗИ и SOC.
Примерно о …
Привет! За время отпуска появилось немного новых фичей в продукте.
1. В бесплатной версии теперь можно отправить обезвреженное ВПО упакованное в архив с паролем 1234. Обычно СЗИ поддерживают такое и перебирают какие-то стандартные (pass, 123, 0000) автоматически, чтобы проверить их содержимое.
2. В платной версии появились первые и самые простые семплы для Linux
3. Теперь можно сделать отправку по расписанию и отпра…
Привет! Мы с обновлениями:
1. В бесплатной версии теперь доступно порядка 286 вариаций атак, в платной — 910.
2. Добавили атаку GrimResource. Это .MSC файл, который эксплуатирует уязвимость в библиотеке и позволяет выполнять код при открытии. Часто его рассылают в архивах, поэтому можете воспользоваться нашей функциональностью упаковки для проверки, как ваши СЗИ себя ведут. На скрине показал, как это сделать
3. Добав…
У нас обновление!
1. Новые семплы и варианты упаковки (различные типы архивов). Зайдите протестировать себя. В сумме в бесплатной версии 190 разных вариантов атак.
2. СЗИ натренировались блокировать нас по телу письма или отправителям, поэтому теперь можно поднять свой SMTP и рассылать с него. Для этого на странице атаки нужно выбрать "Добавить сервер".
3. Теперь можно выбрать с какой почты будет идти атака, это сер…
Shares as published. No per-option vote count is published by Telegram, so none is shown.

Showing the 12 most recent of 16 posts we hold for @knckn. 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.
Stars beside a post are paid reactions — Telegram Stars, bought with money and spent on that post. They are a different unit from reactions and are never added to them, here or anywhere else on this page.
Polls
The poll we hold for this entry, as Telegram rendered it when we read the post. A poll’s figures keep moving after that, so each one is dated.
Shares as published. No per-option vote count is published by Telegram, so none is shown.
Percentages only — there are no per-option vote counts here, because Telegram publishes none. The public post preview gives each option’s share and a single voter total, and nothing else. Multiplying one by the other would produce a per-option tally that looks measured and is not: the shares are rounded to whole numbers before we ever see them. We print what was published and leave the column that does not exist empty.
The shares need not add up to 100. Rounding alone puts many polls at 99 or 101. A poll that allows more than one answer per voter runs well past 100 by design, and several here do. The bars are drawn against a fixed 100% track at each option’s own percentage rather than normalised to the total, so a poll that exceeds it shows that it does instead of being quietly rescaled.
Read from the 16 most recent posts we hold, published 25 April 2024 to 19 March 2025. Telegram labels each poll by kind — an anonymous poll, a quiz, a closed set of final results — and that label is reproduced rather than paraphrased.
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.
Mentions
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
Appears in Telegram’s recommendations for other channels
The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
