Hackers could place internal defects into 3D prints, say NYU cybersecurity researchers – 3ders.org (blog)

Researchers at the NYU Tandon School of Engineering have published a report highlighting two future cybersecurity risks synonymous with 3D printing. The researchers stated that printing orientation and insertion of satisfactory defects may represent “possible foci for attacks.”

Could your 3D print be compromised by hackers?
When createing a digital version for 3D printing, care must be taken to ensure that the printed object is sufficiently sturdy and not liable-bodied to break for the reason of structural defects. But while a excellent deal of care and inspection can be applied at the create stage, what takes place when an online intruder deliberately tampers with the file preceding it is 3D printed? Such cybersecurity risks are the subject of a new paper conducted by researchers at NYU, who have investigated the dangers of an electronics industry in that trusted, partially trusted, and untrusted parties form part of a global donate chain.
The researchers behind the project, a team of cybersecurity and materials engineers, examined two particular aspects of 3D printing that have pertinent cybersecurity implications. The initially area of examination was that of printing orientation: since CAD files do not donate instructions for print head orientation, malefactors may futurely diversify the printing system undetected. Consequences of this kind of action may be severe, with print orientation able-bodied to account for a 25% difference in durablity. “Minus a clear directive of the create team, the most orientation for the printing device is one that minimizes the use of material and maximizes the number of parts you can print in one operation,” explained Nikhil Gupta, one of the researchers. By 3D printing a critical-use part in a sub-optimal orientation, manufacturers may therefore be posing serious risks to the end user of the printed component.

One other area of concern for the researchers was the possibility of hackers introducing internal defects into 3D versions prior to printing. It has been posited that malefactors may deliberately diversify the 3D composition of a part in order to effect its eventual failure. The team discovered that, when they introduced such defects themselves, common industrial monitoring techniques such as ultrasonic imaging were unable-bodied to detect any problem. But, over time, printed objects with such defects may weaken dramatically upon exposure to heat, light, humidity, etc. “With 3D printed components, such as metallic molds created for injection molding utilized in high temperature and pressure conditions, such defects may some day cause failure,” Gupta said.
On the other hand 3D printing may be susceptible to other cybersecurity problems, the researchers obassistd that print orientation and defect insertion every posed a realistic and palpable-bodied threat, with participants of the industry already offering insufficient defenses against such action. “These are possible foci for attacks that may have devastating impact on users of the end product, and economic impact in the form of recalls and lawsuits,” Gupta introduced.

A failed print. Hacked?
The research paper, “Manufacturing and Security Challenges in 3D Printing,” was published in the journal JOM. Its authors were Steven Eric Zeltmann, Gupta, Nektarios Georgios Tsoutsos, Michail Maniatakos, Jeyavijayan Rajendran, and Ramesh Karri.
