1. Social Media Profiles Data Leaked

It contained their names, email addresses, phone numbers, LinkedIn and Facebook profile information. The ElasaticSearch server contained all the information unprotected. Users were not required to enter a password to access or download the data. This data is said to be unique because it contains data sets from two different data enrichment companies. 

2. TrueDialog Data Breach

TrueDialog is an American communications company, based in Austin, TX, USA. It creates SMS solutions for small and large businesses and currently works with 900 cell phone operators around the world.

5. Data Breach 

In April 2019, Diachenko and Vinny Troia, security researchers found a publicly accessible MondoDB database that contained 150 gigabytes of detailed marketing data. It was owned by the email validation company and it leaked 808,539,939 records.

Cyber security incidents are no longer news, in fact, it is a topic that companies are addressing due to the intensity of malicious attacks. But 2019 alone, has experienced major attacks. The total number of breaches exceeded more than 30% and the total number of records exposed up to 112%, said the Data Breach QuickView Report 2019 Q3. Let’s hope this number reduces in the coming year and enterprises hire security testing companies to secure their networks and systems.
