The Poloniex crypto-exchange has sent users emails demanding the replacement of the account password due to leakage of personal information.
In a letter, the exchange said that it had reset its current passwords due to the publication by attackers of a list of email addresses and passwords on Twitter.
Representatives of the company claim that onlya small portion of them can potentially be used to log into existing accounts. However, to avoid risk, passwords were canceled for all accounts tied to email.
Having received such a message, some usersfelt that it was sent by scammers and turned to the community on social networks. This put Poloniex customer support in an awkward position as they had to prove the authenticity of their newsletter.
The exchange has not yet specified the extent and causes of the data leak.
The publication of personal information on social networks isa common tool for hackers, because it not only threatens the security of funds, but also opens up access to accounts to an unlimited number of people. Another recent example is the hacking of the GateHub wallet database, which compromised the security of 1.4 million users.</p>
