Wannacry is not the only one. Most harmful cyberattacks in history

Find out how cybercrime affects you

Over the past year cybercrime increased by 10% and now it is even more profitable than drug trafficking.

Wannacy is a ransomware that blocks access to a company’s systems and files and asks for a ransom for its recovery. It affected 74 countries all over the world. These types of attacks are constantly produced by the thousands and their gateway is usually your email. Because of that you really need to take precautions in order to be safe while being on the Internet.

In addition to this ransomware, with all its risks and negative effects, there are more important cyberattacks in history:

1. YAHOO! (2013)

The biggest cyber attack ever. Hackers stole more than 500 million credentials from Yahoo databases. It was a robbery by super computer experts who accessed to the keys, decrypted them and spent several weeks extracting data.

Among the stolen information there were names, email addresses, phone numbers, birthday dates and security questions. Hopefully, it didn’t include payment card data, bank accounts or recomposed passwords.

Today Yahoo is still contacting potentially affected users and advising them to change their passwords and security questions. Also, Yahoo! communicated that the Russian Government was behind this cyber attack and there is a lot of controversy about it.

As a result of the cyberattack, a lot of people interrupted their loyalty relationships with Yahoo! They can’t trust in a non-safe company and it means a damaged brand image and of course a loss of money.

2. SONY (2014)

In November of 2014, a group called ‘‘Guardians of Peace’’ managed to hack Sony’s computers stealing several unworn movies and e-mails. Hackers tried to extort Sony to shut down the screening of the film The Interview, which is a film about a plot to assassinate North Korean Leader Kim Jong-un. Eventually, it came out that North Korean Government hired and paid those hackers to achieve their goal of stopping the screening of the movie. Sony had to pull the movie because a lot of cinemas refused to screen it for fear of retaliation.

But it wasn’t the only consequence: hackers uploaded 5 new Sony Movies to the Internet -“Steel Hearts,” “Annie,” “Mr. Turner,” “Always Alice,” and “To Write Love On Her Arms.”-. It supposed, for example, that the Brad Pitt movie, Hearts of Steel, had one million illegal downloads in less than a week, causing a huge loss of money.

3. SAUDI ARAMCO (2012)

This oil company suffered one of the most worrying attacks in which the 10% of the world’s oil supply was in danger. Everything started when an Aramco employee opened an e-mail and clicked on an infected link. As a result of the malware effect, the entire company had to disconnect all the computers from the Internet and returned their administrative procedures to the past: paper and fax substituted their Internet communications.

This attack affected the whole population. The malware called Shamoon destroyed 35.000 hard discs and made Aramco buy 50.000 new ones, interrupting the hard discs supply in the entire world. As a consequence of their need of hard discs, Aramco paid even more than the stipulated price; they wanted those hard discs as soon as possible and paying more guaranteed speed. It entailed an increase of the hard discs prices for the entire population. So, if you bought a hard disc between September of 2012 and January of 2013 you paid more for it because of this cyberattack.

The group Cutting Sword of Justice took credit for it but today it’s still a mystery who really did it.


All these cyberattacks are starting a new time, in which cybercrime will cause a lot of struggle to big companies. Information is power, and today there are tons of people threatening our data. The world will collapse the day that cybercriminals steal everything from our databases and that’s why it’s our duty to reach global agreements to fight against this increasing way of crime.
