The security experts from the ZaufanaTrzeciaStrona.pl portal have recently informed about a new free to access database that contains a whopping 1.4 billion usernames and passwords in clear text.

The database contains plain text credentials leaked from the following domains:

- wp.pl

- interia.pl

- o2.pl

- op.pl

- tlen.pl

- vp.pl

- poczta.onet.pl

- onet.pl

- buziaczek.pl

The security experts have analyzed the leak data and as it turns out, the passwords used by internet users were astonishingly simples and not all too difficult to guess. The list of the used “security codes” included: “123456”, “123456789”, “polska”, “111111”, or “qwerty”.

Moreover, the compromised e-mail accounts were also registered on the more specialist domains, such as: .policja.gov.pl, .mon.gov.pl or even .sejm.gov.pl.

To protect yourself, you are strongly advised to stop reusing passwords across multiple sites and always keep strong and complex passwords for your various online accounts. If you want to check if you have been a victim of the data leak, you should go to the "Have I been pwned?" website, and you enter your e-mail address in the search engine.
