Online Betting Sites

Three online betting sites copied 108 million records to Elasticsearch cloud storage earlier this year without securing them. This led to the leakage of users’ names, phone numbers, addresses, IP addresses, account balances, games played, and win-loss information.


Another major security breach that shook the IT sector was the Rubrik database leak. An Amazon Elasticsearch server with inadequate cyber protection was easily hacked. The attackers got their hands on some valuable customer information like names, contact information, and corporate account data.

Dunkin’ Donuts

Hackers used credential stuffing attacks to breach data that affected Dunkin’ Donuts rewards members. The company revealed its data breach for the second time in three months. According to widespread reports, hackers are selling the consumer data to the Dark Web for profits.


The DowJones watchlist leak in 2019 included 2,418,862 identity records on government officials and politicians from every country in the world. It includes publicly available information on prominent individuals.


Facebook publicly admitted that it improperly stored passwords of 600 million users since 2012. The company kept them in plain text, and over 20,000 employees had access to them.

Another Facebook hack this year exposed 540 million records, including account names, user activity, and Facebook ID because of a security flaw in its third-party application Cultura Colectiva. A similar incident involving the app At the Pool disclosed passwords along with photos, groups, events, and check-ins.

Federal Emergency Management Agency (FEMA)

The data included the bio, location, profile photo, verification, email address, and phone number of victims.


Popular online design tool Canva also came under attack this year. The hack compromised usernames, email addresses, and real names of 139 million users. Therefore, the company had no choice but to urge its clients to change their passwords.

Six million users of the dating app Coffee Meets Bagel were victims of a data breach that exposed their names, email addresses. The company informed customers of the attack via email sent on Valentine’s Day. It also called on them to stop revealing personal information through the app.


Evernote’s Web Clipper Chrome extension was also on the receiving end of a cyber attack. Hackers had access to online data of 4.6 million users and got their hands on financials, authentication, and private communications. The company fixed the problem, but the extent and severity of the breach remain unknown.

American Medical Collection Agency

The American Medical Collection Agency breach has to be one of the most concerning corporate attack of 2019.

The massive health-care-related debt collector discovered malicious software infesting their online security from August 2018 to March 2019. The breach led to the exposure of 12 million records, including names, dates of birth, addresses, phone numbers, and dates of medical services.

First American

The real estate and title insurance firm First American’s data security incident is proof that not all security incidents are breaches.

The records included driver’s license images, bank account numbers, Social Security numbers, tax documents, and mortgage papers.

Lessons Learned From 2019 Data Breaches

Several takeaways can help make the rest of 2019 better when it comes to data security. Businesses must improve data protection practices and bring their security act in place.

According to Forbes, 67% of the reported breaches and 84.6% of the exposed records are from the business sector. It is clear for everyone that it falls behind when it comes to deploying safe data security practices.

Therefore, companies must get the basics right before moving on to extensive AI-driven and blockchain-enabled product promises.

Turn to Strong Passwords.

The data breach of Ascension is a clear example of how organizations are neglecting the basics of data privacy and protection.  

A strong password is the first and minimum line of defense against cyber threats. And if you get it wrong, there is always room for error. All companies must understand the importance of using robust and unique passwords for each account or server.

Make Disposable Email Addresses.

If there’s a lesson to learn from the data breach of Coffee Meets Bagel, it’s that companies must introduce disposable emails. Users who have multiple applications on their device would benefit a lot from this feature.

That’s because using a disposable email for dating and gaming apps, for example, would reduce the possibility of hacking attempts. Moreover, consumers should avoid using their work email addresses for personal accounts.

Invest in Vulnerability Scanning

Coinmama’s data breach of 2019 gives a different perspective on securing critical user data. The company’s systems had untracked vulnerabilities, which later caused a significant security breach and massive repercussions.   

To avoid a similar fate to Coinmama, companies should extensively implement vulnerability scanning solutions and release patches of their websites and systems regularly. They should also provide users with tips on how to recognize and avoid suspicious emails.

Adopt End-to-end Encryption

The Earl Enterprise data breach highlights the importance of end-to-end encryption. Financial and payment companies should encrypt user data during the entire transaction. If Earl Enterprise had done so earlier, all the information in its point-of-sale systems would have been safe.

Invest in Security Awareness Training

Another necessary data protection process that most companies ignore is security awareness training. All breach patterns show that insider actions, both malicious and unintentional, lead to the exposure of sensitive records year after year.

According to the Egress Insider Data Breach Survey:

  • 60% of 4,856 personal data breaches reported in the first half of 2019 were a result of human error.
  • 43% of the data breaches happened due to incorrect disclosure.
  • 20% of attacks were successful because of faxing or sending data to the wrong recipient.

Organizations generally fixate on external threats, often forgetting that human error and internal risks are all too common. Of course, not all insider breaches are the result of reckless employees and blunders.

But the point is that corporations must invest in technology that works alongside the user to mitigate the threat coming from the inside. Apart from that, companies must invest time, effort, and money in security awareness training.

It is the ideal way to inform workers about the effects of negligence on the organization.



In conclusion, data breaches can happen to any company at any time. With the advent of technology, attacks are getting more advanced by the day.

The data breaches of 2019 show that the number of malicious attacks is increasing exponentially. Therefore, it is crucial to understand how each breach occurred, and how to protect the company from similar incidents in the days to come.
