Experts warn that even smart toothbrushes can be exploited in DDoS attacks
Some toothbrushes connect to a network via Bluetooth or wireless LAN and record information such as ``how well you brushed your teeth.'' Stefan Zuger of the security firm Fortinet warned that malicious actors could install malware into these smart toothbrushes.

``If your smart toothbrush has an insecure connection, a hacker can install malware on your smart toothbrush and give it commands to access specific websites,'' Zuger says.
If it's just one toothbrush, it won't cause much damage, but if 3 million toothbrushes were to access a website at the same time, that website could be down for several hours due to excessive access.
Zuger said, ``A vulnerability in smart toothbrushes programmed in Java was exploited and 3 million toothbrushes were used in a DDoS attack, collapsing the website of a Swiss company and costing millions of euros (hundreds of millions of yen). ), and points out that even electronic devices that seem unrelated to viruses can become targets for attacks.
Mr. Zuger also conducted a study to determine how long it took for a PC to become infected with a virus when connected to the Internet without any security protection, and the results showed that it took 'less than 20 minutes.' Introducing the episode, he said, ``Every device connected to the Internet is a potential target and can be exploited for attack. Everyone must protect themselves. Yes. Otherwise, sooner or later you will become a victim or your device will be used in an attack.'
