BITSAFE HARDWARE WALLET SOFTWARE
Compromised production process: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product.To date, no wallet in existence is implemented using provably correct software. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Imperfect implementation: the security of all computing devices relies on the quality of their implementation.This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. Insecure RNG ( Random Number Generator): hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet's private keys securely.
When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient's Bitcoin address is recommended.

For example, malware on a PC could monitor for high value transactions and then swap out the recipient's authentic Bitcoin address for an address controlled by the attacker.
How a hardware wallet could fail to protect your Bitcoin: These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. However, it's important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers. To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets.
