In the ever-evolving landscape of Cyber Security, data breaches are one of many common threats that we hear about a lot. However, a new data breach has surfaced, boasting an unprecedented 12 terabytes of information gathered from numerous previous breaches.

This monumental leak spans a staggering 26 billion records and encompasses user data from platforms such as LinkedIn, Twitter, Weibo, Tencent, and others. This has given it a title on the internet as the MOAB (Mother Of All Breaches)


The Data Breach Unveiling

Unlike typical data leaks, the MOAB is not merely a singular breach but a compilation of records meticulously gathered from thousands of sources, including leaks, breaches, and privately sold databases. The sheer volume of data is mind-boggling, with over 3,800 folders representing separate data breaches. The Cybernews data leak checker has been diligently updated to allow individuals to ascertain if their data was exposed in this colossal breach.


Discoveries within the MOAB

Bob Dyachenko and the Cybernews team have delved into the MOAB, revealing not only historical data from previous breaches but also potentially new information that has never been made public before.

The MOAB encompasses 26 billion records, distributed across various folders, hinting at the likelihood of previously unpublished data. The motive behind the MOAB’s creation remains unclear, with researchers speculating that the owner could be a malicious actor, a data broker, or a service dealing with large datasets.

Security experts express deep concern about the dangerous potential of the MOAB. Threat actors could exploit the aggregated data for identity theft, sophisticated phishing schemes, targeted cyberattacks, and unauthorized access to personal and sensitive accounts. With billions of new records, the MOAB poses an unprecedented risk to users’ privacy and security.

A comprehensive examination of the MOAB reveals an extensive collection of records from various breaches. Tencent QQ, a Chinese instant messaging app, leads with 1.4 billion records. Other platforms affected include Weibo (504M), MySpace (360M), Twitter (281M), Deezer (258M), LinkedIn (251M), AdultFriendFinder (220M), Adobe (153M), Canva (143M), VK (101M), Daily Motion (86M), Dropbox (69M), and Telegram (41M).

Notably, the leak also contains records from government organizations in the US, Brazil, Germany, the Philippines, Turkey, and more.


Potential Impact of the Data Breach

The magnitude of the MOAB could have unprecedented consequences for consumers. As many people reuse usernames and passwords across multiple accounts, malicious actors might launch a wave of credential-stuffing attacks. The risk extends to spear-phishing attacks and increased spam emails, putting individuals at heightened vulnerability.

Comparing the MOAB to the 2021 COMB, which contained 3.2 billion records, illustrates the unparalleled scale of this latest breach. In response, Cybernews is updating its data leak checker to include MOAB information. Meanwhile, users are strongly urged to prioritize cyber hygiene, adopt strong passwords, enable multi-factor authentication, and remain vigilant against phishing attempts.



The Supermassive Mother of All Breaches has unleashed a new era of cybersecurity challenges, underscoring the critical need for heightened awareness and proactive measures. As the digital landscape continues to evolve, individuals and organizations must adapt to safeguard their data from the ever-growing threat of cyber breaches. Stay informed, stay secure.
