Bot Logs (Stealer Logs)

Bot logs (also known as Stealer Logs) are comprehensive data packages harvested from an infected device by an Infostealer. These logs contain every piece of sensitive information stored on the machine, including credentials, cookies, and system metadata.

What are Bot Logs? The Digital Payload of Infostealer Malware

In the realm of modern cybercrime, Bot Logs represent the raw product of a successful malware infection. When an Infostealer infects a device, it doesn't just grab a single password; it archives the victim's entire digital life into a single, organized package. These packages, known as "logs," are the primary currency of underground data markets.


Anatomy of a Bot Log File

When a threat actor acquires a bot log, they essentially gain a snapshot of the victim's digital identity. A typical Stealer Log includes:

  1. Stored Credentials: Every username and password saved in web browsers.
  2. Session Cookies: Active tokens that allow access to social media and banking without a password.
  3. Autofill Data: Credit card numbers and personal addresses stored for convenience.
  4. System Metadata: Information about the device's hardware, IP address, and location.


Bot Logs on Dark Web Marketplaces

These logs are traded on specialized platforms where buyers can filter for specific criteria, such as "government employees" or "high-balance crypto users." Proactive defense systems like Dark Radar monitor these marketplaces in real-time. If a log containing corporate credentials appears, it triggers an immediate alert to prevent an impending Account Takeover.


Why Bot Logs are a Corporate Priority

A single bot log from a remote employee’s personal laptop can jeopardize an entire corporate network. If that log contains VPN or cloud service credentials, it provides an open door for Initial Access Brokers. Monitoring for these logs is a critical step in a comprehensive vulnerability assessment strategy.


In summary; Bot logs are ready-to-use attack kits for cybercriminals. Understanding the threat they pose and utilizing Dark Web monitoring is essential for neutralizing the impact of an infostealer infection before it leads to a full-scale breach.
