Data Leak: Collection #2-5 dump leaks 2.2 billion usernames and passwords: Researcher gadgets.ndtv.com

Less than a fortnight after the Collections #1 data leak with over 770 million email IDs and 22 million passwords, the Collections #2-5 data dump have made its way to the Interweb. Carrying unimaginable 2.2 billion usernames and associated passwords, the new data dump is claimed to include 845GB of stolen data, including as many as 25 billion records, an online report revealed. The researcher notes that many of the leaked accounts are duplicate, as they are coming from different previous leaks, and even after weeding them out, the size of the latest dump is close to three times of the Collections #1 dump.
