Phasm

Hidden in plain sight 👻 Hide encrypted messages inside photos. Open-source Rust engine. No servers, no accounts, nothing to upload. Apple/Android Apps for free

@llraphaelhg Yes exactly! In Fortress mode it survives WhatsApp. In Ghost mode – our most secret #stego – it has to be sent as file attachment not photo.

Hiding a message is easy. Surviving a chat app's #recompression isn't.
Phasm's Armor mode survives WhatsApp's standard pipeline end-to-end. #Stego Verified. The receiving side only needs the passphrase.
Insta, Snap, WeChat still destroy it. Working on it.

shadow passphrase it "Plausible" - I you wanna try…

[Phasm @PhasmStego]

Phasm has a mode called #ShadowMessages.
One photo. Independent messages. Each locked with its own passphrase.
If you're forced to unlock it, you give up one. The shadows leave no no statistical trace they were ever there.

@cgaffga The password is "Plausible" :)

#Encryption protects the *contents*. #Steganography hides the *existence* of a message.
A border guard who finds a Signal App has a question to ask. Scrolling a camera roll of street photos doesn't.
That's the threat model that matters in some places.

Built on three things nobody's combined before:
• Pure-Rust JPEG coefficient codec, Open Source
• J-UNIWARD + syndrome-trellis coding (Ghost mode, stealth-first)
• STDM + Reed-Solomon + Fortress sub-mode — the only stego we know of that survives WhatsApp

Hi 👋 We're Phasm — a free, open-source steganography tool that hides encrypted messages inside ordinary JPEGs.
We tested 15 messaging platforms to see what they do to your photos (and what survives):
