Nintendo Switch RSA-PKCS#1 Public Key Recovery

This is a short writeup of a fun (but ultimately pretty useless) attack I implemented on the Nintendo Switch a few months ago resulting in the recovery of some otherwise unobtainable RSA public keys. Since public keys aren't private keys, this is pretty useless, apart from letting us validate some signatures on PC. Even so, the attack is a pretty cool one, so I thought I'd write it up.

Every Switch gamecart has a unique certificate (called its "CERT"), storing an RSA signature followed by some kind of unknown but unique encrypted data. I was trying to reverse how these certificates work, and the obvious first step was to try to see how they were validated. However, when I tried looking through the FileSystem (FS) module, which should be responsible for validating these certificates, I found no references to the format at all. The "CERT" magic number was nowhere to be seen, and I couldn't find an RSA modulus that validated the signatures I had. This was in

I've never had great understanding of launchctl but the deprecation of the old commands with launchctl 2 (10.10) has been terrible as all resources only cover the old commands, and documentation for Apple utilities is generally disgracefully bad, with launchctl not dissembling.

Mad props to https://babodee.wordpress.com/2016/04/09/launchctl-2-0-syntax/ which contains most details

domains

Internally, launchd has several domains, but launchctl 1 would only ask for service names,

Shut down without showing a confirmation dialog:

osascript -e 'tell app "System Events" to shut down'

Shut down after showing a confirmation dialog:

osascript -e 'tell app "loginwindow" to «event aevtrsdn»'

Reboot to {OS}

This a collection of notes and files used in my quest to create "Reboot to Windows" and "Reboot to Linux" scripts (and desktop shortcuts) for Linux and Windows respectively that automatically reboot my system and instruct rEFInd to auto-select the appropriate OS entry.

General Information

The key for achieving this is to modify the EFI Variable PreviousBoot with GUID 36d08fa7-cf0b-42f5-8f14-68df73ed3740, which rEFInd uses to store the last entry selected in the menu and, if using the + default entry, will be used to select the default OS. By doing this, we trick rEFInd into booting the OS we choose without having to be physically there to press the keyboard.

Check if italic font is supported:

$ echo -e "\e[3mitalic\e[23m"

Also check:

$ infocmp $TERM | grep sitm
 sgr0=\E(B\E[m, sitm=\E[3m, smacs=\E(0, smam=\E[?7h,

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:

Question

There's two ways to increase the default font size in browsers:

set a default zoom level > 100% ("page zooming")
set a default font size > 16px ("text scaling")

Option 1 relies on the browser's proportional scaling. This feature was
