Show ▼
The South Korea's National Tax Service publicly exposed the mnemonic recovery phrase for a seized Ledger cold wallet, creating immediate risk that anyone could control the stored crypto assets. Shortly after the leak, 4 million PRTG tokens were transferred out of the wallet, with losses reported at roughly $4.4 million to $4.8 million. The exposure mattered because the seed phrase functioned as the wallet's master key and bypassed the device, PIN, and permission controls.
