Small business battered by cybercrime

Pro

Cybercriminals are increasingly targeting small businesses due to their less sophisticated defences, according to a new report from Symantec.

Companies with 250 employees or less absorbed 18% of targeted cyberattacks in 2011, but the figure jumped to 31% in 2012, Symantec said in its just released Internet Security Threat Report 2013.

"While it can be argued that the rewards of attacking a small business are less than what can be gained from a large enterprise, this is more than compensated by the fact that many small companies are typically less careful in their cyberdefences," the report said.

Organisations between 251 employees to 2,500 were targeted 19% of the time, with companies with more than 2,500 employees making up the remaining 50%, Symantec said. The company said it detected a 42% increase overall in cyberattacks in 2012 compared to 2011.

Employees in research and development and sales functions are prime targets for hackers, and Symantec said it saw a large increase in attacks directed at those roles. "This suggests that attackers are casting a wider net and targeting less senior positions below the executive level in order to gain access to companies," the report said.

The web sites of small businesses also prove attractive to criminals to plant malicious software in order to gain a foothold in other companies. If a user visits a hacked website, the person’s web browser will be probed for software vulnerabilities. The method of using a company’s website as bait is termed a "watering hole" attack by Symantec.

"For example, an attacker may infiltrate a small supplier in order to use it as a spring board into a larger company," Symantec wrote.

Small businesses may have less cash on hand for hackers to steal, but the companies may have other data, such as customer information or intellectual property, that is valued by hackers.

The most attacked industry in 2012 was manufacturing, at 24%. It was followed by finance, insurance and real estate companies at 19% and by non-traditional services at 17%, Symantec said.
