#BestTechWorkCulture

Last night, GRIMM attended the 3rd Annual DC Timmy Awards. The Timmy Awards recognize and celebrate the technology work culture that actively promote creativity, innovation, and learning in the DC area. GRIMM was named a finalist leading into the event and we’re thrilled to have been ultimately recognized as the First Runner-Up for Best Tech Work Culture!


The evening was filled with energy and camaraderie as companies across the region came together to celebrate the innovative leadership embodied by the greater DC tech community. We were thrilled to be recognized among so many other great organizations in the region, especially as we continue to raise the collective profile of the DC tech scene.


When I started GRIMM, I had a vision to tackle the greatest cybersecurity challenges that face our clients, industry and the greater business and government communities. Five years later, we have grown a dynamic and passionate team who strives to make a better world through independent research and the clients we help. This award really honors them: all the employees that breathe life into the organization and make it an amazing, collaborative, and supportive place to work. I am sincerely grateful for them and this recognition is theirs more than anyone’s. Our employees are what make GRIMM what it is and it’s an honor that the culture we’ve created together was recognized by our peers and colleagues.
No man (or woman) is an island. The mythos of the entrepreneur is that they do it alone; it is a team effort. That team extends beyond employees to a supportive network of partners and friends. They have been there for me and for us over the years. There are too many to list and my Oscar speech isn’t that long anyway, thank you for everything.

New Old Bugs in the Linux Kernel

  Introduction Dusting off a few new (old) vulns Have you ever been casually perusing the source code of the Linux kernel and thought to yourself "Wait a minute, that can’t be right"? That’s the position we found ourselves in when we found three bugs in a forgotten corner of the mainline Linux kernel that turned out to be about 15 years old. Unlike most things that we find gathering dust, these bugs turned out to still be good, and one turned out to be useable as a Local Privilege Escalation (LPE) in multiple Linux environments. Who you calling SCSI? The particular subsystem in question is the SCSI (Small Computer System Interface) data transport, which is a standard for transferring data made for connecting computers with peripheral devices, originally via a physical cable, like hard drives. SCSI is a venerable standard originally published in 1986 and was the go-to for server setups, and iSCSI is basically SCSI over TCP. SCSI is still in use today, especially...

Automated Struct Identification with Ghidra

At GRIMM, we do a lot of vulnerability and binary analysis research. As such, we often seek to automate some of the analysis steps and ease the burden on the individual researcher. One task which can be very mundane and time consuming for certain types of programs (C++, firmware, etc), is identifying structures' fields and applying the structure types to the corresponding functions within the decompiler. Thus, this summer we gave one of our interns,  Alex Lin , the task of developing a Ghidra plugin to automatically identify a binary's structs and mark up the decompilation accordingly. Alex's writeup below describes the results of the project, GEARSHIFT, which automates struct identification of function parameters by symbolically interpreting Ghidra's P-Code to determine how each parameter is accessed. The Ghidra plugin described in this blog can be found in our GEARSHIFT repository . Background Ghidra is a binary reverse engineering tool developed by the National Sec...

SOHO Device Exploitation

Netgear R7000 SOHO Device Exploitation After a long day of hard research, it’s fun to relax, kick back, and do something easy. While modern software development processes have vastly improved the quality of commercial software as compared to 10-15 years ago, consumer network devices have largely been left behind. Thus, when it’s time for some quick fun and a nice confidence boost, I like to analyze Small Office/Home Office (SOHO) devices. This blog describes one such session of auditing the Netgear R7000 router , analyzing the resulting vulnerability, and the exploit development process that followed. The write-up and code for the vulnerability described in this blog post can be found in our NotQuite0DayFriday repository. Initial Analysis The first step when analyzing a SOHO device is to obtain the firmware. Thankfully, Netgear’s support website hosts all of the firmwares for the R7000. The Netgear R7000 version 1.0.9.88 firmware used in this blog post can be downloaded from this web...
