The new high-tech 6G wireless technology could be hacked in five minutes using a piece of office paper, an inkjet printer, a metallic foil transfer, and a laminator.
The security flaw which would allow hackers to eavesdrop on 6G wireless signals was discovered by engineering researchers from Rice University and Brown University, who will present their findings and demonstrate the attack this week in San Antonio at ACM WiSec 2022, the Association for Computing Machinery’s annual conference on security and privacy in wireless and mobile networks.
Study co-author Edward Knightly, Rice’s Sheafor-Lindsay professor of electrical and computer engineering, said: “Awareness of a future threat is the first step to counter that threat.”
“The frequencies that are vulnerable to this attack aren’t in use yet, but they are coming and we need to be prepared.”
In the study, Knightly, Brown University engineering professor Daniel Mittleman and colleagues showed an attacker could easily make a sheet of office paper covered with 2D foil symbols — a metasurface — and use it to redirect part of a 150 gigahertz “pencil beam” transmission between two users.
