  • The HOW, WHY, and HUH? Blog on Disputes

    January 30, 2019, Travis Finn, Consultant, CoalfireOne Scanning Services

    As you may know, performing vulnerability scans is a requirement for PCI DSS compliance. One of those specific requirements, described in section 11.2.2, states that quarterly external scanning must be done by a qualified Approved Scanning Vendor. Coalfire just so happens to be an ASV, so if you need these scans we would happily oblige!

  • Epic Holiday Cookie Baking

    December 21, 2018, Jim Allee, Senior Consultant, Coalfire

    One aspect of being a penetration tester that is always rewarding is the process of rabbit-holing into an area of interest and letting the data guide me to my destination. Recently, while updating and testing new code on a custom cookie fuzzing tool (Anomalous Cookie – https://github.com/Coalfire-Research/AnomalousCookie.git/), I discovered a XSS (cross-site scripting) vulnerability on EpicGames.com. While it appeared possible to write a good payload (stealing cookies and injecting malicious JavaScript/BeEF hooking), I had no good way to deliver it. Traditional cookie-stuffing (https://en.wikipedia.org/wiki/Cookie_stuffing) might work to drop the rogue cookie onto a target’s machine; but could there be other ways? If not, this would most certainly be classified as 'Self-XSS.'

  • IoT Adventures: The LeFun WiFi Camera

    October 03, 2018, Esteban Rodriguez, Consultant, Coalfire Labs, Coalfire

    Recently I happened to be in the market for a baby monitor, so I decided to search Amazon for an affordable device that would fit my needs. A search for “baby monitor” within the “electronics” department brought me to the LeFun WiFi Camera. For $39.99 (at the time of my purchase), this seemed like it could be a good deal. Knowing the reputation of Internet of Things (IoT) devices, I was curious about its security. This was addressed in the product description with the guarantee that when I connect to any device, it will be via a “secure and safe network” and will be secured with “financial-level encryption.” It also boasts that they are “CE, FCC, and RoHS certified,” which is good, despite those certifications only dealing with safety and not information security.

  • The Unhealthy Security of Healthcare

    September 25, 2018, Qasim Ijaz, Director, Coalfire Labs

    I have been involved in a number of healthcare penetration tests here at Coalfire and in my previous roles. I have hacked electronic medical records, medical devices, and most importantly, humans. From my time as a systems engineer at a medical device and systems vendor to my current role at Coalfire as a penetration tester, I have seen a few healthcare organizations grow from highly insecure to cyber-fortresses. In this blog, I will highlight the most common issues my teammates and I come across while penetration testing healthcare environments.

  • From OSINT to Internal: Gaining Domain Admin from Outside the Perimeter

    September 11, 2018, Esteban Rodriguez, Consultant, Coalfire Labs, Coalfire

    When I first began working at Coalfire in early 2017, I couldn’t wait to get started pentesting professionally for the first time. When I finally got tasked with my first gig, I dove right in. I was tasked to perform an assessment of the external network. After hitting all known servers and web applications with various scanning tools, I had nothing. For a penetration tester, the assessment does not end here.
