Advanced anomaly detection: how to defeat ransomware

Ransomware has been pervasive since the mid-2000s. The latest forecast, from Cybersecurity Ventures, estimates that global ransomware damage costs will reach $20 billion by 2021. This is a staggering 57x more than it was in 2015. The threat is, in fact, so prevalent that Bitdefender’s 10 in 10 Report revealed almost half of CIO’s (49%) worry a ransomware attack could wipe out their business in the next 12-18 months if they do not increase their investment in cybersecurity.

But it’s not just ransomware itself that is cause for concern. It’s that the nature of ransomware has changed. In its original format, bad actors and cybercriminals would encrypt a company’s IT management systems and demand payment for a release code. To counteract the threat, companies began routine back-ups to prevent a crippling loss of information. Over an extended period, we have seen that cyber criminals are paying attention, so it is not surprising that once again, they have evolved their tactics to defeat defenses.
