it is much more comprehensive than the first Collection. All of the five together comprise about 2.1 billion different E-Mail addresses. “Of which 750 million were not included previously in the database of our Identity Leak checker”, says Chris Pelchen from the HPI. “We found the Collections in a Forum, which we watch permanently.”

It was a Forum in the open-access network, not in the so-called Darknet. In such forums, great packages from various data leaks are compiled again and again, re-titled and then offered for sale. The Collection #1 is about should cost 45 dollars. Often the packages are deployed but at some point, to free Download – so it was the case with the Collections. Asked whether the HPI would spend money to get data and to expand the Identity Leak Checker, says Pelchen: “we are not doing That. This would help the suppliers.”
