Rewind back to May 2015 and the WannaCry ransomware infected 200k+ computers in 150+ countries demanding ransom payments. Since then there have been numerous other ransomware attacks with some more high profile cases such as the ‘NotPetya’ attacks.
There is conflicting evidence around the most recent ransomwares origins with some linking it to the Petya strain and others such as Kaspersky Labs claiming it could be entirely new. One of the largest companies to be hit by the attack were Maersk the shipping giant. So far, the exact method or methods of distribution of the ransomware are not yet known. However, it is suspected that the ransomware is spreading via the same leaked NSA EternalBlue exploit used by WannaCry.
- Ransomware locks or encrypts files on your PC so you can’t use them.
- In return for access, the hackers behind the ransomware demand money.
- It’s usually activated through a phishing email, spam, fake app or bogus software update.
- The ransom frequently takes the form of online currency Bitcoin.
- The sum increases as time goes on – and if unpaid, files are often deleted.
Ransomware in SaaS Applications
Nearly all strains of Ransomware target the key productivity apps, Word and Excel regardless of where they are hosted, be it locally or in the cloud. Ransomware can easily spread to Office 365 via Onedrive and ActiveSync and in G Suite via the Google Drive sync tool.
Its important to retain control over your data when moving it to the cloud and maintaining an offsite backup with a tool such as our UK Backup Cloud to Cloud backup service will ensure you are able to recover data following a ransomware attack.
