STARLINKCLOUD: 123,997 US Plaintext Credentials in the October 9, 2023 Mega-Release

STARLINKCLOUD's October 9, 2023 release exposed 123,997 US plaintext credentials in a single batch -- one of the largest individual Telegram stealer log releases in the entire October 2023 US cluster. The following day, October 10, STARLINKCLOUD released a second batch of 48,769 records. Together, STARLINKCLOUD's two-day total of 172,766 US plaintext credentials far exceeds any other single channel in the cluster. The October 9 release alone -- 123,997 records -- is roughly equivalent to the entire single-day Oct 10 cluster total from all other channels combined. The STARLINKCLOUD name appropriates SpaceX's Starlink satellite brand, projecting network scale and data infrastructure aesthetics to the underground marketplace.


STARLINKCLOUD (October 9, 2023): Stealer Log Summary

  • Records Exposed: 123,997
  • Data Types: Email addresses, plaintext passwords, URLs
  • Breach Type: Stealer log -- credentials harvested from malware-infected endpoints, not a direct database breach
  • Password Type: Plaintext -- captured directly from browser sessions and credential stores by infostealer malware
  • Country: United States
  • Date Leaked: October 9, 2023

123,997 Records: What This Volume Represents

At the typcial infostealer yield of 35-42 records per compromised endpoint, a batch of 123,997 records implies approximately 2,950-3,540 individually infected consumer machines contributing to this dataset. This is not a single-campaign collection -- it represents an aggregated pool of logs from multiple infection campaigns, likely across different US regions and user demographics, consolidated into a single Telegram release. The URL field in each stealer log record identifies the specific services the captured passwords were associated with, giving buyers immediate targeting intelligence for credential stuffing rather than requiring broad indiscriminate attacks.


The October 9, 2023 Context: Dominating the Pre-Cluster

STARLINKCLOUD's 123,997 records on October 9 dominated the entire pre-cluster release day by an overwhelming margin. Other Oct 9 channels -- ArtHouse Cloud Logs (16,663), xl0gs (16,083), Monster Cloud Free 10 (11,748), GODELESS CLOUD (11,514), TOR_LOG MIX566pcs (12,373), PiratesLogs 430pcs (10,725), MIRAGE CLOUD (9,994), TichanCloud Free (8,835), and smaller releases -- combined for roughly 97,000 additional records. STARLINKCLOUD's single batch accounts for more than half the entire Oct 9 release day by volume. The next day's STARLINKCLOUD release (48,769 records) continued this dominance into Oct 10, cementing the channel as the single-highest-volume individual source in the October 2023 US Telegram stealer log market.
