Every botnet operator makes operational mistakes, from the most targeted advanced threat campaign to the simplest click fraud operation. By leveraging a simple technique in Arbor's malware processing system, we are able to mine botnet web servers for inadvertently exposed information. Using the list of URLs visited by malware during sandbox execution as input, we trim the filename from the URL and look for evidence of an open directory that contains other accessible files. Utilizing this technique in the course of the past year, we've found entirely new malware families, detailed logs of infections, unencrypted Bitcoin wallets, and botnet configuration details including passwords.
