According to The Block, Grinex—a Russia-linked cryptocurrency exchange—suspended withdrawals and trading on Thursday after suffering a hack reportedly worth approximately $15 million. Blockchain analytics firm Elliptic stated that the stolen funds consisted of USDT, which were subsequently moved across the Tron and Ethereum networks and swapped for TRX and ETH to reduce the risk of being frozen by Tether. Grinex said its wallet infrastructure was hit by a “large-scale cyberattack,” resulting in losses exceeding 1 billion rubles—approximately $13.1 million. Reports indicate Grinex is widely regarded as one of the successor platforms to sanctioned exchange Garantex, which U.S. authorities targeted last year for facilitating hundreds of millions of dollars in illicit fund flows.
According to The Block, Circle CEO Jeremy Allaire responded at a press conference in Seoul, South Korea, to criticism over Circle’s decision not to freeze the stolen USDC involved in the Drift incident. He stated that Circle fulfills its legal obligations and freezes wallets only upon instruction from law enforcement agencies or courts; unilaterally freezing assets would constitute a “major ethical dilemma.” He also revealed that Circle is engaging with U.S. legislative bodies regarding the Clarity Act, seeking to establish a “safe harbor” mechanism for stablecoin issuers in extreme circumstances—but emphasized that any such authority must be explicitly granted through legislation, not exercised unilaterally by the company.
According to The Block, U.S. musician Garrett Dutton (stage name G. Love) lost 5.9 BTC—worth approximately $420,000—after downloading and using a counterfeit Ledger wallet app from the App Store and entering his recovery phrase. On-chain analyst ZachXBT discovered that the attacker laundered the stolen Bitcoin via the KuCoin platform. This incident once again exposes the security risks posed by fake wallet apps, reminding users to exercise heightened caution when downloading and using cryptocurrency-related applications, and to avoid entering sensitive information through unofficial channels.
According to The Block, Avihu Levy, a researcher at StarkWare, published a paper proposing the Quantum Safe Bitcoin (QSB) scheme, claiming it enables quantum-resistant transactions under Bitcoin’s existing script rules—without requiring a soft fork. This scheme replaces elliptic-curve cryptography with the RIPEMD-160 hash function via a “hash-to-signature” puzzle, thereby enhancing resilience against quantum attacks. The paper notes that QSB’s current per-transaction cost ranges from $75 to $150—significantly higher than today’s average transaction fee—and involves complex user experience; thus, it is recommended only as a “last resort.” The scheme remains constrained by script opcodes and size limits, and does not yet support all use cases—such as the Lightning Network. Compared to BIP-360—which requires protocol-level changes—QSB needs no modifications to the Bitcoin protocol, but remains experimental.
