This kind of issue has become so rampant these days. I dont believe this at first, but some of the exchanges and other online wallets are exposing their customer's email addresses, thats why we're recieving login attempts from different places and it is very alarming already.
No, exchanges and online wallet services aren't exposing people's email addresses. People use one email address for basically everything. In most cases faucets and other trash sites get hacked and their database leaked, so with all that information the hackers try to gain access to exchanges and online wallet services, which is their only objective obviously. With how crypto has increased in value lately these log-in attempts have increased as well.
In other words, use a shitty email account for faucets whatnot, and use new highly secured email accounts for important services. This is common internet etiquette, come on!
Well, that is a very good point, lets add that up as one of the reasons.
We had a discussion here regarding this issue couple of months ago and I was suggesting them that maybe these emails have been used in different website discussions about cryptocurrency, but there were who claimed that they didnt used their emails from any other website except the exchange. So, what we are suspecting was, the involvement of the exchanges in such issue. Idk really, but that was just the closest theory that we ever come up with. I could be wrong, least we can do here is to regularly check our accounts and emails to prevent from being robbed.
Maybe, just make a strong password will be at least 8 characters in length, but the more the better. The longer (more characters) your password is, the more time it will take the hacker to crack it.
