ETERBASE

On September 7, 2020, ETERBASE, a Slovakia-based cryptocurrency exchange, was hacked, resulting in the theft of approximately $5.1 million in cryptocurrencies, including 11.45 BTC ($118,000), 387.4 ETH ($146,000), and ERC-20 tokens, XRP, TRX, XTZ, and ALGO, as reported by Merkle Science. Detected on September 8 at 00:00 UTC, the attack compromised six hot wallets due to private key theft, likely accessed days earlier, as wallets lacked multi-signature security, per The Block. Hackers transferred 11.45 BTC to a main address (1ANLZZ2YFGumRXaD3EMii92zWQgvX2CK9c) and 387.4 ETH to another (0x7860F7b2874e77E80bE0fC6EbfB9414f89781aD9), consolidating funds with 180 BTC from other exchanges, then peeling 430.39 BTC to two addresses and sending most ETH to a major exchange’s hot wallet, per Merkle Science. ETERBASE, with $50 million daily trading volume per CoinGecko, suspended deposits and withdrawals, entered maintenance, and contacted exchanges to freeze funds, per Twitter (@Eterbase). No funds were recovered, and the exchange shut down in 2021, per CoinDesk. One of 208 crypto hacks in 2020 costing $3.7 billion, per Chainalysis, this incident, alongside OKEx’s $5.6 million loss, highlighted hot wallet vulnerabilities, fueling calls for multi-signature wallets, real-time blockchain monitoring, and exchange collaboration to secure crypto platforms.
