The supermassive leak contains data from numerous previous breaches, comprising an astounding 12 terabytes of information, spanning over a mind-boggling 26 billion records. The leak, which contains LinkedIn, Twitter, Weibo, Tencent, and other platforms’ user data, is almost certainly the largest ever discovered.
There are data leaks, and then there’s this. A supermassive Mother of all Breaches (MOAB for short) includes records from thousands of meticulously compiled and reindexed leaks, breaches, and privately sold databases. The full and searchable list is included at the end of this article.
Bob Dyachenko, cybersecurity researcher and owner at SecurityDiscovery.com, together with the Cybernews team, has discovered billions upon billions of exposed records on an open instance whose owner is unlikely ever to be identified.
According to the team, while the leaked dataset contains mostly information from past data breaches, it almost certainly holds new data, that was not published before. For example, the Cybernews data leak checker, which relies on data from all major data leaks, contains information from over 2,500 data breaches with 15 billion records.
The MOAB contains 26 billion records over 3,800 folders, with each folder corresponding to a separate data breach. While this doesn’t mean that the difference between the two automatically translates to previously unpublished data, billions of new records point to a very high probability, the MOAB contains never seen before information.
Researchers believe that the owner of the MOAB has a vested interest in storing large amounts of data and, therefore, could be a malicious actor, data broker, or some service that works with large amounts of data.
“The dataset is extremely dangerous as threat actors could leverage the aggregated data for a wide range of attacks, including identity theft, sophisticated phishing schemes, targeted cyberattacks, and unauthorized access to personal and sensitive accounts,” the researchers said.
