WannaCry: How To Protect Yourself From A Cyber Attack


This week one of the biggest cyber attacks ever has hit computers all over the world. It’s called WannaCry (also WannaCrypt and WannaDecrypt), was first found by the NSA and was then released to the Web by hackers. The ransomware attack has affected systems in the US, China, Russia and Europe.

The ransomware encrypts a computers’ data and demands that they pay a ransom to recover it. The cyber criminals are asking for 300 dollars worth of Bitcoins. If victims don’t pay up within three days, the hackers increase the sum to 600 dollars to pay within seven days. If hackers do not receive payment after that then the encrypted files are permanently locked.

It’s thought that since the attack began on Friday, over 250,000 computers have been infected, including the systems of the NHS (Britain’s National Health Service), FedEx, Deutsche Bahn, LATAM Airlines and Telefonica.

The virus is a wake-up call. Data security should be taken very seriously, more time should be invested in ensuring files are safe.

Computer users should protect their data and practice rigorous security measures in order to protect themselves. As the ransomware was delivered through a Trojan in a hyperlink (which reaches victims either via email, pop-ups, adverts on webpages or via Dropbox links) users should take more care to avoid clicking distrusted links. Phishing emails aren’t always easy to detect, so every user should take care to never open links or attachments from unknown senders and avoid clicking on links that they do not trust.

The WannaCry attack does not affect users of Mac, iPhone or Android. Users of Windows PCs should make sure their software is updated. Additionally, security experts say that wiping your machine and keeping files backed up is one of the safest ways to store data and avoid being a victim of a global cyberattack.

The malicious software looks for pictures, music, word documents and other kinds of file by detecting the application signature. With get2Clouds® encrypted files such information is not detectable by the malware because it is completely destructed and files are broken up into smaller 2GB pieces. Data which has been encrypted using get2Clouds® therefore simply looks like data junk to the ransomware like the Wanna Decryptor.
