In a system designed with iStar-Proton, the workflow is:

In the high-stakes realm of modern military strategy, space is the ultimate high ground. ISTAR—Intelligence, Surveillance, Target Acquisition, and Reconnaissance—is the framework that turns raw data into actionable dominance. While much attention is given to the satellites themselves (the "eyes and ears"), the enablers of this architecture are the heavy-lift launch vehicles. Among them, Russia’s Proton rocket family, particularly the Proton-M, has played a paradoxical yet pivotal role in global ISTAR capabilities.

The engineering team at Istar collaborated with ARM and NVIDIA to create a custom System-on-Chip (SoC) for the Proton line. Here are the headline specifications that make IT managers take notice. istar-proton

We are given a firmware binary and a custom kernel module named istar_proton.ko. The goal is likely to exploit a vulnerability in the kernel module to gain root privileges or retrieve a flag from a protected memory region.

File Analysis:

$ file firmware.bin
firmware.bin: Linux kernel ARM boot executable zImage (little-endian)
$ file istar_proton.ko
istar_proton.ko: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), BuildID[sha1]=...

We are dealing with an ARM-based IoT environment. We need to emulate the environment using QEMU.

Upon executing the exploit:

$ ./exploit
[+] Opening device
[+] Writing to kernel memory...
[+] Triggering modprobe...
[+] Flag: CTFPr0t0n_Collis10n_Detected

In medical settings, latency kills. The Istar-Proton is FDA-cleared for surgical assist. It takes live 3D fluoroscopy data and renders it overlaid on a patient's endoscopic video with less than 1ms of end-to-end latency. This "Proton Vision" mode allows surgeons to see "through" tissue via AR overlays.
