qrxfil: file exfiltration across airgaps using QR codes.
https://github.com/OverkillGuy/qrxfil https://github.com/OverkillGuy/qrxfil
Splits files across multiple QR codes for “sending” across air-gapped computer systems. Generates numbered PNG files to scan.
The codes contain metadata about chunk number (e.g. “007 of 078”) to enable out-of-order scanning.
It's a fun way to learn Rust, and a great trick to get terrified looks from security folks.
- webmaven 6y ago> qrxfil: file exfiltration across airgaps using QR codes. I'm a little confused about the scenario here, how are you getting qrxfil onto the airgapped system, and why doesn't that method allow data egress? For example, using ultrasonic audio as a channel allows you (once installed on the target system via a usb device) to invisibly exfil files to devices with no line of sight to the airgapped system. Another method can steganographicly encode files into benign-seeming printed documents.
