MapleChange, a small Canadian cryptocurrency exchange, claimed to have suffered a bug that allowed hackers to withdraw funds from its exchange. In an announcement on Twitter, MapleChange stated that "Because we have no more funds to pay anyone back, the exchange has to close down unfortunately. This includes all of our social media." Hours after the incident and the shut down of MapleChange's social media accounts, a group of investors found the identity of the CEO of MapleChange, disclosing his name and address on Twitter.
After the disclosure of the CEO's name, MapleChange's Twitter account was reactivated, with the team stating "We have not disappeared guys. We simply turned off our accounts temporarily to think this solution through. We cannot refund everyone all their funds, but we will be opening wallets to whatever we have left so people can (hopefully) withdraw their funds." (Source: CryptoSlate)
