New mutating viruses, like Locky and CryptoLocker, are quickly popping up. And many are infecting small businesses, which are now big targets for hackers.
Undercapitalized and outgunned small businesses are still the weak links in cybersecurity, even though they may have valuable data. Their percentage of IT budget directed to security has been increasing from 4.9 percent in 2010 to 7.9 percent last year, according to Ponemon Institute's annual IT security Tracking study. But spending still lags behind big companies.
Meanwhile, hackers are inventing increasingly sophisticated malware.
