Slow Fog Analysis suggests hardware implantation to steal mnemonic phrases from Ledger

The Chief Information Security Officer of Slow Mist Security, 23pds, stated that if the modification of the Ledger device's PCB is indeed as described by former Mt. Gox CEO Mark Karpelès, the attacker would possess a considerable level of technical skill.23pds mentioned that the possible attack process involves the wallet generating a mnemonic phrase within a secure element and displaying it on the screen for the user to write down. A malicious module could obtain the displayed content through screen data lines such as SPI, record the complete mnemonic phrase, and then send the data to the attacker via LTE/eSIM. The secure element can prevent the private key from being directly read or exported, but it cannot stop external modules from accessing the information currently displayed on the screen. He noted that the above analysis is based on the premise that the PCB has indeed been modified in the described manner, and the relevant attack paths and hardware implantation still require independent verification.Mark Karpelès previously stated that a Ledger hardware wallet he received was suspected of being implanted with a spy module. The device came from Malaysia, the outer packaging was intact with shrink wrap, and the implant was hidden in the position where the screen originally had a cushion, containing LTE communication components, an antenna, eSIM, and a microcontroller connected to the Ledger SPI bus, capable of analyzing the characters displayed to the user and sending relevant data after the mnemonic phrase setup is completed.

first_img Analysis: MoonPay Commerce's on-chain monthly transaction volume has dropped to approximately 7.3 million USD

User obchakevich_ published 23 months of on-chain data for MoonPay Commerce, a subsidiary of the payment company MoonPay, covering the period from November 2024 to September 2026. MoonPay announced the acquisition of the payment service Helio on January 13, 2025, which was later renamed MoonPay Commerce, with products still operating under the pre-acquisition smart contracts; the parties did not disclose the price, but Fox Business reported it to be $175 million, while Fintech Futures referred to it as an all-equity transaction. Helio was founded in London in 2022 and claimed to have over 6,000 merchants and cumulative transactions exceeding $1.5 billion at the time of acquisition, integrating with Discord, Shopify, and WooCommerce.The on-chain transaction volume three months before the acquisition was $100.3 million, with fees of $1.08 million, resulting in an annualized fee of about $4.3 million, with the reported price being approximately 40 times that annualized fee. The total transaction volume for the entire year of 2025 was $141.9 million, with fees of $1.59 million; the transaction volume over the past 12 months was $90.7 million, with fees of about $930,000, making the reported price approximately 190 times the latter. Monthly transaction volume decreased from $39.8 million in January 2025 to $9.6 million in March, and $7.3 million in September 2026, with an effective fee rate maintained between 1.05% and 1.20% over the 23 months.

first_img Decrypt launches Money Accounts on Solana, unifying balance coverage for prediction markets and perpetual contracts

According to Decrypt, Decrypt has announced that its self-custody Money Accounts are now live on Solana, providing readers with a single balance that can be used across all Decrypt products to support its financial and intelligence market, The Information Exchange. Decrypt co-founder Ilan Hazan stated that the goal is to achieve one account and one balance, allowing users to utilize various financial tools directly from where they obtain information, from prediction markets to perpetual contracts and swaps. Users can manage all positions in one place without worrying about wallets, cross-chain bridges, or public chains, with relevant partners to be announced in the coming weeks.Deposits and balances are denominated in USDT on Solana, and the same balance can support products such as Earn, Swaps, Predictions, and Perps. Gas and rent are sponsored through joint signatures by payers, so users do not need to hold SOL or consider network fees. The account operates in a self-custody mode, meaning Decrypt does not hold private keys and cannot perform operations on behalf of users, with a private key export feature coming soon. Cross-chain operations are completed at the underlying level; for example, the Myriad Predictions market settles on the BNB Chain, yet users can still trade using the same Solana USDT balance without needing to interact with a cross-chain bridge.Existing Myriad Wallet users can directly use Decrypt Money Accounts, with one account and one balance covering both Decrypt and Myriad without the need for migration.
