Victims Lost US$1B to Ransomware
Over the course of 2016, ransomware operators trailed their sights on bigger targets—companies and organizations, both large and small—and raked in US$1 billion for their efforts.
Even before WannaCry reared its ugly head, companies and individuals worldwide have already been suffering the threat’s dire consequences—all documented in Trend Micro’s report, "Ransomware: Past, Present, and Future." After just one year, the world saw a staggering 752% increase in the number of ransomware families.
Several modifications to different ransomware variants were seen throughout 2016. New capabilities include updated infection routines and the ability to encrypt an increasing number of file types. To date, there haven’t been the end of the "ransomware scare."
Case in point: WannaCry—probably the biggest ransomware to hit users—abused a recently discovered Windows Server Message Block (SMB) vulnerability (CVE-2017-0144) to get into not just systems but entire networks. Exploiting the bug allowed cybercriminals not just to encrypt files in systems but also scan for SMB shares to spread in networks. Because WannaCry encrypted even business-critical files (e.g., databases and archives), victims could have been left with no choice but to pay up.
Despite the fact that WannaCry asks for a smaller ransom (US$300) compared with other variants, it can spread via SMB shares. This means the affected company may have to pay US$300 per infected system—thickly lining the operators’ pockets while crippling the victims.
WannaCry isn’t the first to profit off businesses though. Cerber—the most prolific ransomware family to date—wreak havoc among victims over and over again. Its operators have even started peddling Cerber-as-a-service offerings in underground forums, earning US$200,000 for a single month last year.
Ever-changing ransomware behaviors are forcing victims to pay up just to keep their businesses running. Note though that paying up doesn’t always mean you’ll get access to your data back. When it comes to threats like ransomware, prevention is always better than cure.
Trend Micro recommends organizations take some basic precautions to minimize their risk of this threat. Below are steps they can take.
