Title: How does Cobo Vault work? Post by: bitbro678 on November 28, 2018, 02:11:52 AM How does Cobo Vault broadcast to the blockchain? WiFi?
Title: Re: How does Cobo Vault work? Post by: Dragonbro123 on November 28, 2018, 02:38:29 AM Looks like it's using a mobile app as the hot device to broadcast transactions to the blockchain. From what i've read, the cobo vault has no network connections or usb.

I believe the transmission from the cobo vault to the mobile phone happens via scanning QR codes, and the broadcast itself is happening from the mobile. However, a hardware wallet which claims to be extremely secure 'because of no communication channel' while at the same time using updates via a SD card, shouldn't be taken too seriously. Without any further information about the EXACT handling of firmware updates, one could theoretically create a malicious update (spread via mobile application vulnerability for example) to compromise the cobo vault. Note that i do not intend to say that there is a vulnerability, i am just mentioning the 'easiest' way to eventually attack this wallet (without further information about this wallet). No wallet is 100% secure. |
