The database contained the record of 65 million users which included their IP addresses, email addresses, the tips to models, and more.

4. Raychat

Raychat is a business and social messaging app in Iran and it was also a victim of a massive data breach. Nearly 150 million user accounts ended up being exposed to the web and it was later destroyed by a bot during a cyberattack. The company had stored its user data on a misconfigured database, which left them vulnerable.

5. Brazilian Database

One of the major personal data breaches in the history of Brazil happened in January 2021. Technoblog reported the data sets while it was initially identified by PSafe. The exposed database contained names, facial images, phone numbers, credit score, salary, email, and more. It also contained the data of millions of deceased individuals.

6. Socialarks

A server that belonged to Socialarks was discovered by Safety Detective researchers. It was identified that the server had scrapped profiles of over 214 social media users. The data was obtained from LinkedIn, Instagram, and Facebook. The database also contained over 318 million records and data of over 408 GB.

7. Bykea

Another major data breach that was discovered by the Safety Detective researchers team involved Bykea. During a routine IP address check, the team found an Elastic server vulnerability on certain ports. The server contained API logs for a transportation, logistics, and cash on delivery company called Bykea. The data contained the full names, locations, and other personal information of approximately 400 million users.

8. LinkedIn

It might come as a surprise to several readers when they hear that the data of approximately 700 million users were put on sale online.

A massive database that contained over 5 billion records was discovered by Diachenko in 2021. A cyber analytics company, Cognyte stored the database as part of their cyber intelligence service that was used to notify customers about third-party data exposures.


What’s more worrying is that there has been a considerable increase when it comes to data transparency breaches at both the private and government organization levels. Experts in the field of cybersecurity claim that if this trend continues, then it will result in a huge impact on the cybersecurity risk management strategies of several businesses. Moreover, it is best for companies to ensure that the breach notifications are not done on the fly in the wake of a security incident in the uncertain and stressed hours or days following an incident. Companies should expect that a security incident will occur, and entities must allocate resources for mitigating the impact of an incident – including funds for pre-planning responses to those incidents.
