The UK’s National Cyber Security Centre (NCSC) recently released its cyber incident trends report for the period between October 2018 and April 2019. The report covers five main cyber attack trends seen in the UK – (1) attacks on Office 365 deployments (and cloud services in general), (2) ransomware, (3) phishing, (4) vulnerability scanning, and (5) supply-chain attacks. “All the incident types noted have resulted in compromises within the UK, some significant in nature,” it says.
Ransomware is a type of malware which encrypts your personal files and sells the decryption key back to you for a ransom, normally in the range of hundreds to thousands of dollars.
Although the earliest examples of what could be considered modern ransomware date back to the beginning of 2012, ransomware became a widespread phenomenon towards the end of 2013 with the release of CryptoLocker.
The dramatic rise of ransomware can be explained by a combination of several factors: the ease at which criminals can deploy a working system, an increase in the use of Tor and bitcoin, as well as its high and immediate return on investment.
