Firewall3D Aims to Protect Your 3D Printer Against Attacks from Malicious Firmware
Researchers at Texas A&M University's department of electrical and computer engineering have come up with a way to protect 3D printers from attacks via specially-crafted firmware updates that could exfiltrate data or even permanently damage the printer's hardware: Firewall3D.
"As the 3D printing market continues to grow rapidly, with an estimated value exceeding $30 billion, cybersecurity risks and attacks targeting additive manufacturing systems are also increasing," co-authors Seyed Ali Ghazi Asgar and Narasimha Reddy explain by way of background to their project. "These attacks aim to sabotage printed components, steal intellectual property, or even physically damage the 3D printer itself. One major cybersecurity threat in this domain is firmware level attacks, which can be introduced through supply chain compromises, malicious firmware updates, or insider threats that deploy modified firmware to manipulate printer behavior. To defend against such threats, we propose a dedicated hardware based security solution, Firewall3D, that acts as...
