Do you’ve got an Anycubic Kobra 2 Professional/Plus/Max 3D printer?  Do you know it has a safety vulnerability?

When you answered “sure” to each these questions, then likelihood is that I can guess simply how you discovered your 3D printer was susceptible to hackers.

My guess is that you just might need learnt about the issue after seeing a wierd message displayed in your machine, claiming that it had been hacked.

As a number of posts on Reddit affirm, homeowners of the 3D printers have had an uncommon message pop up on their gadgets.

The message incorporates ASCII artwork of a worm and claims to be “innocent” – however warns of a “crucial vulnerability” within the printer, posing a “vital risk”. It advises affected customers to disconnect their printer from the web to keep away from being hacked.

Within the message, somebody calling themselves “printer god” bemoans Anycubic’s lax safety and warns {that a} malicious assault may have induced harm.

The warning message within the file hacked_machine_readme.gcode could be safely deleted from the printer’s display or USB drive.  The writer claims to have despatched it to over 2.9 million susceptible printers.

The hack appears to be related to a post in an internet discussion board earlier this week by a person known as “Dump”.  “Dump” claimed to have tried to speak with Anycubic for 2 months about “two crucial safety vulnerabilities” – with one described as “catastrophic if discovered to be malicious.”

Anycubic has now confirmed the existence of a “security issue”, which it claims was “attributable to a 3rd occasion utilizing a safety vulnerability of the MQTT server to entry customers’ printers.”

Anycubic says that it’s enhancing its cloud server safety and can launch new firmware to customers on March 5, 2024.

This is not the primary time that printers have been hijacked by way of safety vulnerabilities to unfold messages. As an illustration, in 2018, 1000’s of printers had been seized to print out a message promoting PewDiePie’s YouTube channel.
