Ransomware has been around in some form or another for years, but the recent rise in cheap and accessible ransomware such as the Stampado variant, which is available for just $50, is particularly worrying. This spike is an indication of an accelerating evolution of the threat landscape and is the direct result of the digital transformation of crime. However, being successful at spreading ransomware does require a very broad set of criminal skills, including blackmailing, negotiation, money laundering and the ability to digest monetary success.

Simply put, organisations have to adapt to the growing threat of ransomware by deploying a more comprehensive approach to protect their digital assets and communications. For example, ransomware is a good example of how a well-deployed backup process can play a decisive role in limiting the damage of cyber attacks, not just malfunctioning equipment.

Malicious emails are getting more sophisticated and more targeted, making it easier for employees to be tricked into clicking on a suspicious link, which might lead to the ransomware being installed. It only takes one person clicking on the wrong link or opening the wrong attachment to give ransomware the opportunity it needs to infect a whole system. A layered defence of next generation firewalls, email security and backup can provide what’s known as a “secure trinity”. Together they can protect not just against ransomware, but also against the next waves of digital crime.
