How Attackers Use Password Combolists in Brute-Force Campaigns
The file is a specific data compilation frequently discussed in cybersecurity communities as part of the broader ALIEN TXTBASE leak. This file is a "combolist"—a plain text document containing username/email and password pairs used by malicious actors for credential stuffing attacks. Analysis of the 310K USA Combolist 310K COMBOLIST USA.txt
Files like "310K COMBOLIST USA.txt" often consist of recycled credentials from older, unrelated data breaches rather than fresh, malware-stolen logs. These lists are curated for credential stuffing ,
These lists are curated for credential stuffing , where attackers use automated bots to test the leaked pairs across multiple popular websites, exploiting the common habit of password reuse. unrelated data breaches rather than fresh
Experts suggest that many of these lists are bundled together with fabricated data to inflate record counts, making them more attractive for sale on dark web forums or Telegram.
While specific academic "papers" on this single text file are rare, forensic analysis from cybersecurity firms like and Specops Software reveals several key characteristics of such files within the ALIEN TXTBASE dataset:
Analysis of similar files in the dump showed a high volume of junk data , including randomly generated or non-existent email addresses and structurally incorrect records.
