r/TREZOR

Hey everyone,
I recently purchased a Trezor Safe 7 for long-term cryptocurrency storage, and I’d like to better understand its physical security protections, particularly against sophisticated supply-chain attacks.
I’ve been researching recent hardware wallet security incidents and would appreciate some technical insight into the following questions:
Physical Tampering: How difficult would it be for a sophisticated attacker to open a Trezor Safe 7, modify its internal electronics, and reseal the enclosure without leaving visible evidence?
Malicious Hardware: Could someone theoretically install a malicious component inside the device, such as a chip connected to the display or other internal circuitry, to compromise sensitive information?
Authenticity Verification: Does Trezor Suite’s authenticity verification detect physical hardware modifications, or does it primarily verify the identity and integrity of specific security components?
Tamper Detection: Does the Safe 7 have built-in mechanisms to detect or record whether its enclosure has been opened?
Supply-Chain Protection: What specific security measures distinguish the Safe 7 from earlier Trezor models when it comes to preventing sophisticated physical attacks?
Limitations: If a Safe 7 successfully passes authenticity verification, how much confidence should users have that the device hasn’t been physically modified? What attack scenarios might remain undetected?
I’m particularly interested in understanding the difference between cryptographic authenticity verification and physical tamper detection.
My goal is not to spread fear or suggest that Trezor devices are compromised. I simply want to better understand the security model and its limitations before trusting the device with significant long-term holdings.
I’d especially appreciate answers supported by technical documentation, security research, or official Trezor resources.

the title says it, in light of this ledger attack, i want to look inside my trezor devices

but it seems like impossible to open the safe 3 without breaking whole casing

there's a metal plate on the back, is it glued to the device? or how does it attach?

i couldn't find proper instructions on the internet either, only for trezor safe 7

any help appreciated

If you can’t get around third-party email distribution that constantly exposes your customers to data breaches here’s a thought …

Don’t use email to market to existing customers. It’s not necessary in this space. For example, I know of many blockchain projects and I didn’t stumble upon them because they sent me an email. Crypto investors and even more so, self-custody crypto investors are a different breed of customers. We research, discover, use X, Reddit, discords, etc to try and make informed decisions. Email is just not factored into that equation. If you rely on email to know when Trezor Safe 8 is available, you have to be a very small percentage of Trezor’s customer base, yet to reach you Trezor exposes us all to 3rd party data leaks.

It’s a new day. Maybe rethink marketing is all I’m asking. Don’t use the Nike or Apple playbook. That’s not your main customer type. In fact, if I NEVER receive another marketing email from Trezor I will still be well informed of the latest device. How about you?
