Bithumb, a South Korean-based, one of the world’s largest cryptocurrencies exchanges, has been recently hacked, resulting in compromising a large number of user accounts and loss of over one million dollars worth of electronic currency. Money was not the thieves’ only prize, as they have also stolen personnal information of nearly 32 thousand Bithumb users. Information stolen included names and both physical and e-mail addresses.

According to Bithumb, attack on the company was possible due to two factors: first one was one of the company’s employee’s home PC being hacked; second was that a large number of Bithumb’s clients were using the so-called ”disposable passwords” when carrying out online transactions (disposable password is a single-use password that gets changed after logging out of a given service). How exacly did these two factors play into making the theft possible is unknown, at least officially.

Well over 100 Bithumb customers have already filed a complaint against the company. South Korean officials are investigating the crime as we speak.

So… how about keeping your money in a sock instead?
