The responsible for the sale of the huge trove of data goes online by the moniker of “C0rpz.” C0rpz has collected a huge trove of data through credential stuffing, the ‘Collection #1’ archive is a set of email addresses and passwords totalling 2,692,818,238 rows resulting from thousands of different sources.

According to Hunt, there are 1,160,253,228 unique combinations of email addresses and passwords, while the unique email addresses totalled 772,904,991.

“Recorded Future assesses with moderate confidence that the original creator and seller of Collection #1 was the actor “C0rpz.”” reads the analysis published by Recorded Future.

“Another actor from a well-known Russian hacking forum was also observed sharing a large database of 100 billion user accounts, which possibly has some of the same datasets found in Collection #1. “

Collection #1 was included in a larger dump containing seven other databases:

    “ANTIPUBLIC #1” (102.04 GB)
    “AP MYR & ZABUGOR #2” (19.49 GB)
    “Collection #1” (87.18 GB)
    “Collection #2” (528.50 GB)
    “Collection #3” (37.18 GB)
    “Collection #4” (178.58 GB)
    “Collection #5” (40.56 GB)

While the AntiPublic dump had already leaked online, the remaining ones were seen for the first time in the hacking underground last month.

According to Recorded Future, C0rpz sold the archives to other hackers that offered them for sale on multiple hacking forums, the collections were also distributed for free via online sharing service MEGA and via torrent magnet links.

Sanix and Clorox are two hackers who bought the data from C0rpz, the former was identified by the investigator Brian Krebs as the source of Collection 1, the latter is the individual who shared Collection for free on Raid Forums.

All the hackers mentioned by Recorded Future were seen for the first time by the experts of the company after the disclosure of Collection #1, they were not involved in previous campaigns or operations.
