Secret drive, public meltdown
My USB Drive Has a Hidden Encrypted Vault
A secret stash on a normal-looking USB — and the comments instantly turned into a fight
TLDR: Phantomdrive is a USB stick that pretends to be normal but can reveal a hidden locked storage area with a password trick. Commenters immediately split between praising the clever idea and mocking the whole “secret” concept as something serious investigators would spot fast, making the debate as big as the device.
A maker just unveiled Phantomdrive, an open-source USB stick designed to look boring and harmless until you type in a secret password line, at which point it swaps to a hidden encrypted storage area. The pitch is pure spy-movie energy: a gadget meant to help people protect private files from nosy officials, corrupt police, or anyone demanding access. But the real fireworks didn’t come from the hardware — they came from the crowd.
The biggest reaction was a loud, skeptical “nice try, but the government is not that dumb.” One of the strongest commenters argued that if ordinary people can buy and use a “hidden” drive, then state-level investigators can absolutely learn to spot it too. Another piled on with the brutally simple take that plausible deniability only works if nobody knows hidden volumes exist — which is awkward when you’re literally buying one from a project built around that idea. Ouch.
Still, not everyone was throwing tomatoes. Some commenters were genuinely impressed, calling it a clever solution and comparing it to old-school hacker conference gadgets. Others joked that rule number one of secret tricks is not posting your secret trick online, which became the thread’s funniest running gag. And in a messy side plot, the creator also complained about AI-generated bug reports and a Reddit dogpile, giving the whole thing an extra layer of internet-chaos spice. So yes: cool gadget, huge debate, and commenters split between “this is slick” and “this is stealth cosplay.”
Key Points
- •The article introduces Phantomdrive as an open-source USB drive that shows only an 8 GB partition by default and hides the remaining storage from the operating system.
- •A plaintext password trigger on the visible drive causes the device to unmount and remount a hidden partition, with AES-256 encryption and decryption performed in place.
- •The hardware design centers on the CH569 chip and currently uses an SD card instead of eMMC because the author says eMMC prices are elevated due to AI-related demand.
- •The project’s firmware, hardware, mechanical design, and design tools are described as fully open source.
- •The article explains its cryptographic approach, including testing against OpenSSL and the use of a unique device-specific salt derived from the USB serial identifier for key derivation and recovery.
