Liquid Network Federation Wallet Drained of 4000 BTC in Alleged White-Hat Exploit Exposing L-BTC Minting Flaw

Bitget Loses $351 Million in Record 2026 Crypto Theft After Attackers Forge Internal Transfers

Bitget's hot and warm wallets were drained of approximately $351 million on September 24, marking the largest known single crypto theft of 2026. Attackers did not steal private keys but instead forged internal transfer requests that bypassed approval workflows. The stolen assets spanned at least five blockchains, with the largest portion being roughly 103 million XRP worth about $157 million. Bitget's CEO Gracy Chen attributed the incident to North Korean hackers based on IP patterns, behavioral signatures, and on-chain evidence matching prior operations. The exchange maintains a $464 million user protection fund sufficient to cover all losses, while deposits and trading remain unaffected and only withdrawals are temporarily frozen. The case highlights how process-level compromises can bypass even robust key-management controls in cryptocurrency exchanges.

Address Substitution Attacks Exploit Partial Address Checks in Crypto Wallets

Address poisoning, clipboard hijackers, and supply-chain malware all rely on users verifying only the first and last few characters of long blockchain addresses. Researchers detail real incidents including a May 2024 theft of 1,155 WBTC worth roughly 68 million dollars where an attacker poisoned transaction history after a test transfer. Studies from Carnegie Mellon University show that even security-conscious users miss mismatches in truncated addresses 21 to 38 percent of the time. Existing identicons such as Jazzicon and Blockies can be matched by attackers because they depend on only the first eight hex characters. The team released the open-source Humanized Hash library that renders any address or hash as a 4x4 grid of colored shapes using PBKDF2 stretching, making forgery computationally expensive. Calculations indicate that matching both the visual pattern and edge characters requires tens to millions of GPU-years on current hardware. The library supports multiple languages with identical output and carries an MIT license with a fixed algorithm.

Monero Web Wallet Built on Official monero-wallet-rpc Adds Digest Authentication, Two-Phase Transfers and BigInt Precision

A developer created a non-custodial Monero web wallet that runs entirely on the user's machine and communicates only with a personal monero-wallet-rpc instance. The project retained all key-handling logic inside the official RPC daemon while adding a custom backend, frontend and supporting infrastructure. Eight practical challenges were documented, including HTTP Digest authentication that is tightly coupled to TCP connections and the silent loss of monetary precision caused by JSON.stringify on large numbers. The solution introduced two-phase transaction submission to reduce the risk of broadcast errors and replaced floating-point arithmetic with BigInt to guarantee exact handling of Monero amounts. The resulting implementation demonstrates how to expose a convenient web interface without introducing custodial risk or weakening the security model of the Monero wallet RPC.
