DAY 7

The laptop dual boots, the Linux side is encrypted, Secure Boot is off, and I have decided that is acceptable.

project

IoT Sensor Simulator

A virtual edge device that reads, stores and uploads sensor data, so the whole pipeline can be built without the hardware.

DAY 6

I tried to get Secure Boot working on the Linux side and I could not.

DAY 5

Fixed the double passphrase with a keyfile stored inside the initramfs.

DAY 4

Now the machine asks me for the same passphrase twice, every single boot.

DAY 3

The Linux side is encrypted with LUKS2, so the disk is unreadable without the passphrase.

The human behind the terminal

I'm Sotaro, a student at the University of Melbourne. I designed and implemented software such as IoT pipelines and web apps, and I'm currently taking on security challenges on Hack The Box.

Background: I studied at a high school in New Zealand for a year and a bit and a high school in Malaysia for 2 years (online for a year due to COVID, the rest on campus) since I left Japan when I was 13 years old. These experiences are the reason why I can adapt to unfamiliar environments and systems.
