Introducing dumpmon: A Twitter-bot that Monitors Paste-Sites for Account/Database Dumps and Other Interesting Content

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.

Automatically Enumerating Google API Keys from Github Search

Introduction

Github recently introduced its new and improved search feature. While the improvements make search for content much easier, it has certainly introduced its share of problems as well. This is just another example.

Automated Open Source Intelligence (OSINT) Using APIs

Introduction

The first step to performing any successful security engagement is reconnaissance. How much information one is able to enumerate about given personnel (for social engineering engagements) or systems can often impact the effectiveness of the engagement. In this post, we will discuss what Open Source Intelligence (OSINT) is and why it takes so much time, as well as ways we can use various application programming interfaces (APIs) to automate much of this process for us. Hopefully this post will help shed light on the importance of proper privacy settings, and the threat of automated information gathering due to APIs.
