What The Credential Labels Really Sell.

We hand-read 160 Botnet Log posts and 80 Combolist posts. The labels do not name one product: under Botnet Log, bank-account listings (23.8%) and game-account lots (21.3%) outnumber strict stealer-log clouds (6.3%), all weighted estimates. Counts are collected posts in a Telegram-dominated collection, not offers, sellers, victims or a market total.

01Key findings

Accounts, Dumps And Buying Instructions

Each finding below is stated in its own unit, with the limit that comes with it. The investigations give the full reasoning and the evidence records.

What the label holds · n = 160

What a "Botnet Log" label holds.

Hand-read kept posts, n = 160. Weighted share of posts with 95% interval.

  1. 01Under the Botnet Log label, bank-account listings and requests (23.8%), game-account lots (21.3%, moderate confidence) and buy-side rate sheets (17.0%) each outnumber strict stealer-log clouds (6.3%) in 160 hand-read posts. All are weighted estimates.
  2. 02Credential files and pointers are the largest group in 80 hand-read Combolist posts (36.8%, interval 25.8-47.7). Of 175 bulk-combolist asking posts in the Combolist class that state an amount, 97 state an access period and 1 a per-line price. The unit extractor is 49-74% accurate, so this is a pattern, not a count.
  3. 03Credential-list subscriptions get cheaper by the day. 233 distinct plan texts hold 174 eligible ladder segments with three or more core tiers. In 144 of them (83%), the computed per-day price falls at every step. The plans advertise recurring drops for a set period; the adverts do not show what is delivered or renewed.
  4. 04Reposted Combolist texts use claim words about twice as often. 57 distinct repeated texts say fresh 49%, private 30% and valid 32%. The 2,661 posts whose text we did not see twice say 26%, 15% and 14%. The pattern does not hold in the Botnet Log class or the keyword set, and the words are seller wording, not tested properties.
  5. 05Buyer rate sheets treat the second factor as a deliverable. 47.5% of 59 hand-coded rate posts require a 2FA-secret column and 57.6% a cookie column. That fits supplier-enrolled accounts better than accounts handed over as found (a reading, not a fact).
02The investigations

Four Questions. One Data Set.

Each investigation answers a different question from the same collected posts. Start with the main one, then follow the question that matters to your team.

Main investigation
What "Botnet Log" and "Combolist" Posts Actually Sell

Hand-read Botnet Log and Combolist posts hold bank listings, game lots, rate sheets and subscriptions. Strict stealer-log clouds are 6.3% of Botnet Log, a weighted estimate.

03For defenders

Where Account Preparation Leaves Clues

These are implications of what the posts say, not measured control results. Each one points to a different decision.

  1. Ask which product a "botnet log" mention is before you act: bank listings go to fraud, session and cookie material to identity operations, strict stealer clouds to endpoint response.

  2. For a combolist mention, match your own domains and users once per distinct file, reset passwords and revoke sessions on a match. Claim words such as fresh, private and valid trigger nothing.

  3. These advertised prices do not establish a risk ranking: denomination and product comparability across posts are not established. A subscription advert does not show what is delivered, so act on a verified match of your own accounts.

  4. Watch enrolment and session behaviour: buyer rate sheets ask for 2FA-secret and cookie columns, which fits supplier-enrolled accounts better than accounts handed over as found.

160 kept (cleaned) Blackhole posts carrying the Botnet Log class label, 1 Jan-27 Oct 2026, drawn with stratum weights (set x quarter). We labelled them from full text, blind to our classifier. Strict stealer-log clouds are priced or joinable feeds and log packs said to come from infected machines.

Weighted estimate: 6.3% (95% interval 2.6-10.4); 7.4% with unpriced promotions. Unweighted, 9 of the 160 posts (5.6%). The same sample holds bank-account listings and requests 23.8% (17.1-31.1), game-account lots 21.3% (15.1-28.0) and buy-side rate sheets 17.0% (11.1-23.0).
