Nearly 60 percent of small businesses have been the victims of a cyberattack over the past year, but the vast majority didn’t realize that they had been attacked, according to Nationwide’s third annual survey of 1,069 businesses with fewer than 299 employees. Initially, only 13 percent of the participating companies said they had been victims of a cyberattack. However, after they were shown a list of cyberattack types — ranging from phishing scams to trojan horses to ransomware — that figure shot up to 58 percent.
