MMalware prevention is a key priority for CISOs as part of their overall cybersecurity strategy. All forms of malware have the potential to cause significant damage to organisations, and as a particularly destructive threat, ransomware should be top of mind when it comes to having robust cybersecurity infrastructure. Ransomware has been an ever-present threat to businesses of all shapes and sizes for almost two decades. While it was originally conceived as a means to extort money from individuals, it wasn’t long before cybercriminals realised it was just as effective – and far more profitable – to use against organisations as well. Within just a few years, ransomware like Reveton, CryptoLocker and more recently, Wannacry, was being used to bring businesses around the world to their knees, with victims ranging from corporate entities and local governments, to universities and medical centres. In short, no one was safe. As awareness of the threat grew, many organisations upped their cybersecurity game significantly and it wasn’t long before additional investment in both technology and employee security training started to translate into a noticeable fall in ransomware attack volumes globally. For a while, it even seemed like ransomware was heading for the rubbish heap. However, a recent resurgence has propelled ransomware right back to the top of the cyberthreat list. The question is, what’s behind it? As unlikely as it may sound, there’s a growing body of evidence to suggest that the rise of the cybersecurity insurance industry may well have played a key role in ransomware’s renaissance. In this article, we’ll look at some of this evidence and evaluate whether something designed to be part of the solution to cybercrime has unintentionally become a large part of the problem. Cybersecurity insurance – an unlikely villain? FEATURE simply encrypting victims’ data and demanding money for its return like they used to, many have quickly learned that threatening to release it publicly is a great way to expedite a desired response. That’s because in the age of the Internet, public exposure poses far greater risks to many victims, including potentially fatal reputational damage, as well as significant regulatory fines in some cases. For this reason, it’s no surprise that cybersecurity insurance has exploded in recent years, as organisations scramble to protect themselves as best they can against such a potent threat. However, this rise in cybersecurity insurance has quickly created unexpected problems, primarily because so many victims are now finding it far quicker and easier to simply pay the ransom through their insurance rather than trying to deal with the fallout themselves. The more victims use insurers to pay ransoms this way, the more criminals are encouraged to keep carrying out attacks.
