  Sybil attacks have been a concern in the cryptocurrency industry for quite some time. Another notable example is the Binance hack in 2019. Although the attack was not solely a Sybil attack, the hackers used Sybil-like techniques to bypass the exchange's security measures. They created numerous fake accounts and used them to orchestrate a large-scale phishing campaign, tricking users into revealing their login credentials. This allowed the hackers to gain unauthorized access to user accounts and steal a significant amount of funds. Binance has since enhanced its security protocols to prevent similar attacks in the future.
