Back in 2018 Binance had been targeted by a large scale attack by a group of phishers. They made a bounty offer of $250k in BNB to anyone who could provide information leading to their arrest. In the Medium post they provided a list of known phishing domains for people to investigate. I went through the list to see which of the sites were still active: Domain IP kykoin.com 178.208.83.9 bitxumb.
