A recent incident involving 3D printers has shown how important it is to ensure cloud security. Owners of Bambu Lab 3D-printers learned the hard way that cloud security is important last week. They woke up to find their printers printing all on their own.
Bambu reports it experienced a “cloud outage” that led to the possessed printers. The issue caused a backlog in print messages which were sent to random users at the same time when the problem was resolved. Unfortunately, some of these printers were damaged because there was a previous print still on the machine’s plate and so it started a new print right on top of the old one.
Bambu has stated that they will send out replacement parts as soon as possible to anyone whose printer is damaged. The company also detailed several planned improvements that will prevent the same thing from happening in future. They’ve already updated their Cloud Service’s SDK service logic and “increased the database connection sizes for better throughput.” They also plan to update their cloud so that “every time print is initiated, the printer will check the time stamp and automatically discard any outdated print which does not follow our strict configuration.”
