TL;DR
I created a Twitter-bot which monitors multiple paste sites for different types of content (account/database dumps, network device configuration files, etc.). You can find it on Twitter and on Github.
Introduction
Paste-sites such as Pastebin, Pastie, Slexy, and many others offer users (often anonymously) the ability to upload raw text of their choice. This is helpful in many scenarios, such as sending a crash report to someone or pasting temporary code. However, in addition to some people not being careful with what they upload (leaving passwords and other sensitive data in the text), attackers have been starting to use these sites to share post-compromise data, including user account data, database dumps, URLs of compromised sites, and more.
Since there are so many users uploading text to these sites, it's often difficult to find these interesting files manually. While techniques such as Google Alerts can be applied, the results are often a day or two old and are sometimes deleted. This prompted me to create a tool which monitors these sites in "real-time" (less than a minute of delay for the slowest sites) for specific expressions, and then automatically rank, aggregate, and post these results to Twitter for further analysis. I call this tool DumpMon.
