Apparently, it happened that some Amazon Web Services S3 storage buckets were not safe because of Accenture.

These servers were public, anyone could have downloaded this information without any particular effort.

Data breaches: 9. Carbon Black

DirectDefense (a security solution provider), during the month of August, dicovered an important weak spot. This vulnrability concerns Carbon Black, particularly its endpoint detection and response (EDR). The focus is on the multi-scanner service that Carbon Black uses to upload files.

Cloudflare in February:

“1 in every 3.3 million requests could have been leaked.”

This was said in February of last year, while the hacking included: PII data, passwords, encryption keys, HTTP POST bodies, HTTP cookies and HTTPS requests. What caused this leak?

Data breaches: 3. Uber

This specific data breach took place in 2016 but has only been disclosed in 2017. Hackers managed to gain access to more than 50 million accounts of riders and drivers. Company management paid the hackers a significant amount in order to not disclose the information about the data breach and delete all the stolen data.

Data breaches: 2. Verizon

As we approach the number one data breach, the danger grows. 14 million Verizon customers (around the 10% of the total subscribers) – the ones who called Verizon service line during a six months time frame – were affected.  PINs, names and numbers were part of the material exposed. This is some real evidence that supports the idea of switching to a cloud-based data protection practice.

Data breaches: 1. Equifax

Here we are to number one. Last September Equifax said that a huge data breach affected around 140 million customers on July 29. Basically, it was caused by a vulnerability in the US website app that granted the access to some files. The whole leak included names, Social Security numbers, addresses, birth dates, personal information documents and credit card numbers
