Understanding Stealer Logs and Their Role in Security Testing — Part 1

Summary

• Stealer logs contain sensitive data such as credentials, cookies and other personally identifiable information, which are generated by malware specifically designed to steal this type of data.
• In this article we define the concepts of stealer logs, how the malware infections the users and the different types of information that can be stolen by the stealer.
• We also detail the challenges and how to use this type of data to identify Indicators of Compromise (IoC).
• Finally, we provide a case study where it is shown how the tester can use the stealer logs to uncover vulnerabilities.
