Cyber-attack can happen to any digital user at any time and at any place.

Some might be harmless or might cause just a little damage. But there are a few types of cyber-attacks that have caused significant damage and have taken entry in the list of most significant cyber-attacks.

1. Cyber-attack on Yahoo！

One of the most prominent Internet giant， Yahoo suffered a big blow when the security of their 3 billion user accounts was put on stake.

The names， dates of birth， email addresses， passwords as well as security questions and answers of 3 billion users were put on stake. The attack took place in 2013-2014.

The attack had severely affected the company; the Yahoo group that was once valued at $100 billion was finally sold off to Verizon for only $4.48 billion for its core Internet business.

The name of the company was later changed to Altaba， Inc. after the sale.

2. eBay cyber-attack

Another cyber-attack that shook the entire world was the users database hacking by the intruders.

The e-commerce giant was subjected to a major cyber-attack in May 2014 when hackers intruded into the users database using their corporate employees accounts.

The hackers had complete access into their network for about 229 days. The breach compromised the sensitive information like names， dates of birth， addresses， and encrypted passwords of around 145 million users.

But as per the company， the financial data of the customers was safe as it was stored in a separate database and was not compromised. The breach resulted in widespread criticism of the company and incurred great losses.

3. Equifax cyber-attack

Equifax one of the US largest credit bureaus， faced a major blow when the data of its 143 million costumers was hacked.

The customers sensitive information including birth dates， Social Security Numbers， addresses， and drivers license numbers was hacked by the intruders.

The attack did not end with hacking only the personal information; even the credit card information of around 209，000 consumers was stolen too.

According to the company， the application vulnerability on their site resulted in the data attack. The attack was exposed on July 29， 2017， but was suspected to have started in mid-May the same year.

4. Target stores data breach

End of December 2013 gave a big blow to Target stores when they discovered that a data breach into their system had compromised the credit/debit card details and/or contact information of around 110 million people.

The hackers penetrated into their private network by exploiting their vulnerability through a third-party vender for HVAC system to POS payment card readers. The cyber-attack cost them around $162 million.

The CEO and CIO of the company had to resign after this major cyber-security issue.

5. Uber cyber-security breach

Data breaches are common events in the current digital world. How the companies deal with it， also plays an equally important role. Uber was subjected to a data breach in late 2016. The company was not much criticized as its take on this attack was.

The breach resulted in compromising names， mobile phone numbers and email addresses of 57 million Uber users and 600，000 Uber drivers driver license numbers.

The company discovered the breach in late 2016 but made it public almost after a year. Not only that the company offered the hackers an amount of massive $100，000 to destroy the data without verifying they actually did.

The breach had resulted in the loss of both the reputation and finances of the company. The company was in negotiation to sell its stakes to Softbank， at the time the breach was announced. The breach lowered the value of the deal from $68 billion to $48 billion.

6. JP Morgan Chase data breach

JP Morgan， one of the finest banks of the USA suffered from a cyber-attack which compromised the contact information—names， addresses， phone numbers and email addresses of 6 million households and 7 million small businesses.

There were no monetary losses. The hackers gained privilege over 90 bank servers. July of 2014 would really have been tough for JP Morgan to have a deal with all such critical issues.

7. Cyber-attack on Sony PlayStation Network

One of the biggest data breaches in the gaming industry of all times happened on the Sony PlayStation Network. April 20， 2011， is a date that will always be remembered in the gaming industry for the biggest data breach in the gaming industry.

The hackers hacked 77 million Network accounts. These accounts had 12 million accounts that had unencrypted credit card numbers.

The hackers hacked full names， e-mails， credit card numbers， passwords， purchase history， PSN/Qriocity logins and passwords， and home addresses.

Sony incurred losses of an estimate of $171 million. It resulted in an initial $15 million reimbursement in a lawsuit over the breach.

8. RSA Security Attack

March 2011， is a date that is still in debates for the cyber-security breach of the mighty security giants SecurID authentication tokens of the company RSA.

The hackers successfully managed to perform phishing attack on RSA employees and impersonated as individuals and intruded into the network of the company. The attack is estimated to have stolen 40 million employee records.

9. Adobe cyber-attack

Another big cyber-attack that shook the IT giant Adobe happened in October 2013.

The attack compromised the personal information including customer names， IDs， passwords and debit and credit card information of over 38 million users.

The company paid $1 million as legal fees to resolve prerogatives of violating the Customer Records Act and biased business practices.

When market biggies like Yahoo， eBay， Equifax， etc. can get trapped in the trap of cyber-attacks， you too can！ So be aware and follow all cyber-security safety measures religiously and BE SAFE！
