Up to 143 million people in the US, UK, and Canada could have been affected by a hack in February on consumer credit rating company Equifax. The hack was done by exploiting software vulnerabilities and resulted in millions of peoples social security numbers and other private information being stolen, which could be used by criminals to take our credit cards and loans fraudulently.


Cloudflare is one of the largest content delivery networks and DDOS mitigation services. In February a Google security researcher found a bug which was leaking very sensitive user information such as login details and even security keys. The bug could potentially have aided hackers in gaining access to user accounts of Cloudflare’s customers including big names as OKCupid, Fitbit, and Uber.

On a semi-positive note, the hacker group Anonymous pulled down a very large portion of the ‘dark web’ by hacking the web hosting service Freedom Hosting. A large number of the sites operating on the onion network were sites sharing child pornography.


By far the most controversial and widely publicized cybersecurity attack of 2017. The Wannacry ransomware attack affected computers by encrypting data and demanding bitcoin payment for removing the data encryption. Organizations worldwide were infected by the attack, the most well-known being the British National Health Service.
