According to Troy Hunt, a specialist in the field of cybersecurity, there was a massive drain of information in the entire history of observations. A spam vulnerability was detected on the server of the company sending spam. As a result, millions of personal passwords, as well as a database of email addresses turned out to be in general access. A certain server of one of the spammers was so vulnerable that anyone who could get access to the data was able to. Not even credentials are needed. True, in reality, there are not many actually used mail addresses. Some of them are not working now, others are fake, some are simply repeated. The database contains passwords in millions of units. It is possible that in order to send advertisements from third parties, spammers also used other people’s accounts. According to Troy Hunt, passwords could have been taken from large-scale leaks that happened earlier. Moreover, on his website this case was at the top of the hit parade of the largest leaks. Prior to this, the largest drain occurred in the past, 2016, the year. Then 593 million addresses with passwords suffered. Hunt himself recently released a password-checking service. It contains three hundred and six million insufficiently reliable combinations. There you can check whether your personal mail was in the list with leaks.
