In August 2016, the technology recruitment site GeekedIn left a MongoDB database exposed and over 8M records were extracted by an unknown third party. The breached data was originally scraped from GitHub in violation of their terms of use and contained information exposed in public profiles, including over 1 million members' email addresses. Full details on the incident (including how impacted members can see their leaked data) are covered in the blog post on 8 million GitHub profiles were leaked from GeekedIn's MongoDB - here's how to see yours.
In January 2017, a massive trove of data from River City Media was found exposed online. The data was found to contain almost 1.4 billion records including email and IP addresses, names and physical addresses, all of which was used as part of an enormous spam operation. Once de-duplicated, there were 393 million unique email addresses within the exposed data.
This collection is part of a larger series of data dumps, including Collections #1 through #5, which compiled email addresses and passwords from thousands of sources, from previously known data breaches and some new alleged breaches. Collection #1 alone contained about 2.7 billion records, including 1.2 billion unique email and password combinations, 773 million unique email addresses, and 21 million unique plaintext passwords. Additional collections, named Collections #2 through #5, along with "AP MYR&ZABUGOR #2" and "ANTIPUBLIC #1," were also discovered, significantly adding to the scope of compromised data.
In June 2020, the user-generated stories website Wattpad suffered a huge data breach that exposed almost 270 million records.
