#coldcard漏洞被盗594枚btc
Brothers, 594 Bitcoins, $38 million, 25 minutes, 500 wallets—gone!
And this isn’t a phishing site theft, and it’s not that the private keys leaked. It’s a fatal vulnerability in Coldcard’s own firmware.
Do you know how absurd this is? In March 2021, a single line of code bypassed the hardware random number generator, switching to generate the mnemonic using the chip’s serial number plus the clock value. The serial number is fixed, and the clock value is predictable—effectively, your safe-deposit box password is made from the factory ID plus the current time! The attacker sits at home and, in minutes, calculates your private keys.
Even more heartbreaking: the victims welded the wallets into their safes, cut off the network, and didn’t touch them for months, thinking they were safe. So what happened? The hackers didn’t even need to touch your device at all—they remotely computed your private keys and transferred the funds away.
Tell me, what’s the difference between this and getting your faith stabbed?
This isn’t over. The latest on-chain data shows the scale of the theft may be far more than 594. After the discovery of the third-wave attack cluster, total losses are estimated to have jumped to 1,367 BTC—worth about $88.6 million—affecting over 4,500 addresses.
It’s not just older Mk3 models affected. Mk4 and Mk5 before 5.6.0, and Q mnemonics generated before 1.5.0Q—all of them have issues. The effective entropy is only 72 bits instead of 128. Almost the entire line is compromised.
Now what do we do? Coldcard brothers, check your firmware version immediately! If the mnemonic was generated on an affected version, it’s already exposed by default. Updating the firmware doesn’t fix the seed that already exists—you must generate a brand-new mnemonic on the updated device, create new addresses, and migrate all assets over. Do a small test first, then move the full balance.
Vice President Strive said a sentence that sends a chill down the industry’s spine: “This permanently changes people’s confidence in self-custody.”
Hardware wallet = absolutely secure? Starting today, this claim no longer holds.
Brothers, it’s fine to keep your own private keys—but don’t put all your eggs in one basket. Use multisig, multiple providers, multiple devices, multiple physical locations, or go straight to institutional custody. In this industry, never assume something is “foolproof.”
