18 posts held, back to 14 May 2025 — 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 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 18 posts for this entry, the most recent from 10 February 2026. An engagement rate over an empty window would be a number about nothing.
20 reactions across 5 posts, in 3 distinct kinds. The most used accounts for 55.0% of them.
| Reaction | Count | Share | Share, drawn |

| ❤ | 5 | 25.0% | |

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 7 of the 18 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 20reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 18 most recent posts we hold, published 14 May 2025 to 10 February 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
🔴شناسایی بیش از ۴ میلیون فعالیت سایبری علیه زیرساختهای کشور رئیس مرکز افتا: 🔴 هکرها در بازهٔ ۲۰ دی تا ۵ بهمن بیش از ۴ میلیونبار تلاش کردند سامانههای حیاتی کشور را بررسی کنند؛ اما بهدلیل کنترل ترافیک اینترنت هیچ یک از این تلاشها موفق نبوده است. 🔴 در این بازهٔ زمانی، در مجموع حدود ۴۰۰ رخداد سایبری ثبت شد که بیشترین آنها مربوط به زیرساختهای انرژی و حوزههای پولی و مالی بود. 🎖️ @FarhikhteganOnline

🔧 ابزارهای استخراج هش پسوردها 🔪 یکی از معروفترین ابزارها، pwdump7 است. این ابزار هش پسوردهای LM و NTLM را از فایل SAM امکانپذیر میکند. همچنین میتوان به ابزارهای دیگر نیز اشاره نمود: - Mimikatz - DSInternals - hashcat - PyCrack 🏮 نکته مهم آن است که در حالت معمول، برای استفاده از این ابزارها به دسترسیهای سطح admin نیاز است. 🇮🇷 @utPentest
🔑 نحوه ذخیرهسازی پسوردها در SAM فایل SAM در آدرس زیر ذخیره گردیده است: %SystemRoot%\system32\config\SAM این فایل، هش پسوردهای LM یا NTLM را ذخیره میکند. البته که NTLM جایگزین LM شده است چرا که LM مستعد کرک شدن است. هرچند نسخههای جدید ویندوز برای backward compatibility هنوز از LM پشتیبانی میکنند. 🇮🇷 @utPentest

Showing the 12 most recent of 18 posts we hold for @utPentest. 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.
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 18 most recent posts we hold, published 14 May 2025 to 10 February 2026. 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.
Citation-graph rank — 626,367 of 1,160,990entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
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.
Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
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.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 8 August 2026 — this entry's latest reading, not the date you are reading this.
