Initial Access Offers: The Report

We coded posts under Blackhole's "Initial Access Selling" label one by one. Most of the offers were footholds on websites and servers. Corporate network access was a thin, repetitive slice.

02The Evidence

Brandefense Blackhole, our cybercrime database, collects around 17 to 23 million dark web and Telegram posts a month. Reading that volume by hand, and linking a recruitment ad on one forum to a leak-site claim on another and a price list in a Telegram channel weeks later, is beyond what a human team can do alone.

Claude Opus 5.5 prepared the research: it searched the data, sorted and translated posts and drafted the text. Codex Astra then checked every number against the dataset files and tested each claim, and anything that did not hold was removed. Brandefense analysts reviewed and approved the findings.

  1. 01Counts are Blackhole-collected posts, Telegram-dominated, with limited forum coverage. They are not offers, sellers, victims, accesses or incidents.
  2. 02The label is a classifier output. In an AI-coded sample only 38.2% of January–August posts and 4.9% of 12 September–27 October posts were access offers.
  3. 03No claim is made about dark web growth or decline, or about the access-selling market size. The 12 September step is a step in labelled posts, not evidence of more access sales.
  4. 04No trend is claimed across the May–July classifier taxonomy break.
  5. 05The corporate catalogue (120 offers) is a lower bound with unknown pattern recall; revenue, sector, EDR and privilege are unverified seller claims; counts are offers, not sellers.
