Mother of all breaches: 26 billion records exposed What do we know so far?

Users of popular services, including Twitter, Dropbox, LinkedIn, Adobe, Canva, and Telegram, were taken aback this week by the discovery of a 'super breach' comprising 26 billion records of user information. This breach, rapidly dubbed the 'Mother of All Breaches' (MOAB), encompasses a staggering 12 terabytes of leaked user data from these services.

Bob Dyachenko, a cybersecurity researcher at, in collaboration with researchers from, unearthed these records in openly accessible digital storage.

 At this juncture, the owner of this storage remains unknown. However, suspicions lean toward a malevolent actor or a data broker who has been aggregating data from historical data breaches, leaks, and privately traded databases.




  • The 'MOAB' poses a significant threat, with the potential for cybercriminals to exploit the amalgamated data for various forms of attacks, including identity theft, sophisticated phishing schemes, and targeted cyber assaults.

  • Users are advised to verify if their information has been compromised, update their passwords, activate multi-factor authentication, and exercise vigilance against phishing emails.

  • Organizations are strongly encouraged to implement comprehensive data protection strategies to mitigate the repercussions of such breaches.

  • While the majority of the data was compiled from previous breaches, researchers indicate a 'very high probability' that it contains records previously undisclosed. This revelation coincides with Microsoft's recent announcement that Russian-state-sponsored hackers gained access to some executive emails towards the end of the past year.


The sheer scale of these records is astonishing, but how concerned should we be? Although most of the data appears to be from previous incidents, centralizing it in one location heightens the risk of cyber attackers leveraging this data repository for future cybercrimes. Notable websites affected by the leak include Tencent, with 1.5 billion records compromised, Twitter with 228 million records compromised, LinkedIn, AdultFriendFinder, Zynga, Adobe, and Canva.


The researchers at have emphasized, '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 Bottom Line?

Don't panic. While the 'Mother of All Breaches' presents a substantial threat, proactively safeguarding your online accounts by updating your passwords and enabling multi-factor authentication significantly diminishes the risk of being compromised. Adhering to these fundamental measures and remaining vigilant in identifying and reporting phishing emails will contribute to ensuring your online safety.

Furthermore, if the 'MOAB' primarily comprises previously disclosed data, the information available on individuals may not be more vulnerable than it was last week—although the likelihood of malicious actors scouring through these records may have increased.
