A white-hacker demonstrated how he hacked SpaceX’s satellite-based web system Starlink. The researcher might efficiently compromise the goal Starlink Consumer Terminal utilizing a $25 software.
Starlink Consumer Terminal Hacked By way of Fault Injection Assault
Safety researcher Lennert Wouters has shared particulars of his experimental hacking on Starlink terminals on the current Black Hat USA 2022. Saying about it in his tweet, the researcher acknowledged,
I’m excited to announce that our speak “Glitched on Earth by people” will probably be introduced at @BlackHatEvents!
I’ll cowl how we glitched the Starlink Consumer Terminal SoC bootrom utilizing a modchip to acquire root.This could be the primary tweet despatched by a rooted Starlink UT! #BHUSA pic.twitter.com/0XMMIidEKk

In response to a Wired report, the analysis costed Wouters $25, as he meddled with a Starlink person terminal (UT) – the satellite tv for pc dishes in customers’ houses that supply connectivity – attaching a customized modchip to the dish.
Explaining Starlink UT, the researcher talked about in his presentation,
The UT makes use of a customized quad-core Cortex-A53 System-on-Chip (SoC) that implements verified boot based mostly on the ARM trusted firmware (TF-A) undertaking. The early stage TF-A bootloaders, and specifically the immutable ROM bootloader embrace customized fault injection countermeasures.
Nonetheless, the modified dish {hardware} with the researcher’s modchip enabled him to bypass signature verification.
Mainly, the customized modchip consisted of a flash storage, a Raspberry Pi microcontroller, digital switches and a voltage regulator. Wouters then soldered the modchip to Starlink dish board. This {hardware} tweak enabled the researcher to carry out the voltage fault injection assault brief the system and bypass Starlink’s safety.
After that, the researcher began the assault by first focusing on the ROM bootloader, adopted by the others. Finally, he might acquire entry to the dish software program and execute arbitrary code.
The researcher claimed that this assault technique would trigger “unfixable compromise” to the Starlink UT, additional enabling the entry to the Starlink community.
SpaceX Responds Assuring Safety To “Regular Customers”
After discovering the vulnerability the researcher reached out to Starlink by way of its bug bounty program on Bugcrowd final 12 months.
The distributors acknowledged the researcher’s effort and began growing a repair, finally releasing it with a subsequent firmware replace.
Following the general public disclosure of the flaw, SpaceX Starlink issued an in depth paper, highlighting Starlink’s safety measures. They assured the customers about thorough safety, asking them to not fear concerning the assault. Additionally, they appreciated this analysis, terming it “technically spectacular”.
Nonetheless, the researcher believes evading the patch stays doable, although, it will be tougher now.
For curious souls, Wouter has publicly launched the modchip on GitHub. Nonetheless, he doesn’t plan to promote ready modchips, neither is he keen to make the patched firmware public to keep away from malicious exploitation.
