Just because a business is small doesn't mean it's invisible to hackers or immune to attacks. All it takes is for a cybercriminal to exploit a single point of weakness, or an employee to make a mistake, and an SMB could be on the hook for thousands of dollars, or worse.
A few years ago, most attacks were random and indiscriminate, with no purpose other than to cause damage. Today's attacks are typically targeted at particular organizations, with equally specific motives — to extract as much money or data as possible — and small businesses are increasingly in the crosshairs.
Nearly a third of all malware attacks targeted businesses with 250 employees or less in 2012, according to Symantec's 2013 Internet Threat Report. Damage can be substantial.
Last winter, a small family-owned chain of electronics stores in the Northeast was attacked by a gang of Eastern European cybercriminals who installed a piece of malware on the chain’s network to harvest customers' credit card numbers.
After quietly collecting data for six months, the crooks charged nearly $3 million worth of fraudulent credit card transactions before the malware was detected, says Aaron Messing, an attorney with Olender Feldman LLP , who is representing the chain.
The chain requested its name not be used in this story, lest it once again become a target for attackers. While its credit card issuer absorbed the losses stemming from the bogus charges, it also levied a penalty of more than $100,000 on the chain for allegedly violating security agreements. The fine is currently under appeal.
“One of the biggest misconceptions SMBs have is that they're too small to be noticed by cybercriminals,” says Messing. “That's simply not the case. Because they handle sensitive information like credit card data, they're always going to be a target.”
In fact, crooks prefer to attack SMBs; in part, because most lack the enterprise-level security required to repel attacks, says Brian Burch, vice president of SMB marketing for Symantec. Thanks to the Internet, criminals can target thousands of individual businesses at a time. With the ability to extract a few hundred dollars from each, there’s little incentive to put in the effort or risk of going after that one big score.
There are dozens of ways attackers can profit from infecting an SMB. With access to a firm's accounting systems, they can pay themselves for fictional products or cut paychecks for phantom employees. They can lock SMBs out of their own computers and demand ransom in return for the passwords, or steal employees' personal information (or the company's intellectual property) and sell it on the black market. They can infect every computer on a business's network and rent them out as part of a botnet for other attackers. With access privileges, they can attack larger enterprises the SMB does business with.
“No company is too small to attract the attention of cybercriminals,” notes Burch. “No crook in his right mind would accept the risk of robbing a bank for just $200, but he'd happily attack thousands of businesses for that amount, hoping that 500 of them prove vulnerable. And the only way you'd know you've been attacked is when the money starts disappearing.”
Usually it takes some kind of disaster for an SMB to focus on cybersecurity. That was the case at Jones & Wenner, a regional insurance firm in Fairlawn, Ohio, with a dozen employees. About seven years ago, J&W found itself on the wrong end of the Anna Kournikova virus, says Vice President of Administration Joyce Sigler.
“It went wild and shut us down for a couple of days,” she says. “These things usually strike quick and hard, and it's tough to get your hands around them all at once. Afterward, we said we never wanted that to happen to us again.”
Shortly thereafter, J&W contracted with AppRiver, a cloud-based security provider, to handle all of its web hosting, email and Internet traffic. Since then the firm has been malware free, Sigler says.
Ironically, one type of insurance J&W specializes in is cyber insurance against losses from hack attacks and other data spills.
Every employee needs to practice good cyber hygiene, says Monica Hamilton, an SMB product and solutions marketing director for McAfee. That means securing every device that must access the company network, enforcing strict password management policies and assessing vulnerabilities — including how to deploy effective counter measures.
But the biggest hurdle may be getting over the notion that being small brings immunity to attack. It doesn't.
