@P3b7_ @DonjonLedger Also this info should have been posted on the main ledger account so people know to update. There is zero mention of it there. You have one job - security and you keep fucking it up. Not everyone follows the feed of every team member.

There's some FUD circulating about Ledger signers, pushed by a "smart contract security" company claiming a vulnerability in the Ledger Ethereum app.
There was a bug concerning certain clear signing flows. It was found by the @DonjonLedger using their AI-powered vulnerability

You can now sell AI tokens on https://t.co/vZAX4FD1i8 against USDC.
At first I thought it was a nice idea.
Remember when hackers and insiders were running Bitcoin miners on company infrastructure? Same scheme, new substrate. Except now the compute being siphoned isn't hashing

@P3b7_ The key you posted is from here, but the comment explicitly says "make all docker use same enclave.key -- we could have better way to manage this secret, although this one is meaningless and just acts like a id."

🚨Taiko drained for ~$1.7M. Root cause: a private key committed to a public GitHub repo.
enclave-key.pem, the RSA key used to sign all of Taiko's SGX enclaves, sat in the public taikoxyz/raiko repo. That key is the whole trust model.
The attacker derived MrSigner from the https:

If you use a Ledger or hardware wallet with clear signing, you are not at risk.
