Is your banking practices putting your business at risk? Protect your small business accounts from cybercriminals. The Wall Street Journal offers the following suggestions for small businesses seeking to ward off an attack:
Defend your Computer
Hackers often take aim at small firms’ computers because they are easier to infiltrate than banks’ systems. One common mode of attack is to send a “spear phishing” email containing an infected file or a link to a malicious Web site to employees with access to the firm’s financial accounts. Once the employee opens the attachment or goes to the Web site, malware is installed on the computer that allows criminals to access banking logins and passwords. While up-to-date antivirus software offers substantial protection against malware, it isn’t 100% effective.
Accessing your bank account through a computer that isn’t used for anything else—no email or Web surfing—and isn’t connected to the local network offers strong protection, says William Nelson, president of the Financial Services Information Sharing and Analysis Center, an industry group that collects and shares threat data.
Another option is to use an obscure computer operating system such as Ubuntu or Web browser such as Opera because attackers rarely create malware for them, security experts say.
If you use Microsoft Corp.’s Internet Explorer browser, make sure you have the latest version, IE 8, which includes security features to help prevent attacks. Consider using Explorer in “protected mode,” which restricts files that try to install on a computer without the user’s consent, and set your “Internet zone security” to “high,” which disables some of Explorer’s less-secure features, according to Microsoft.
Protect your Accounts
Ask your bank to set up “dual controls” on your account so that each transaction requires the approval of two people—a good guard against fraud, security experts say. Establish a daily limit on how much money can be transferred out of your account, and require that all transfers be prescheduled by phone or confirmed via phone call or text message. If possible, impose restrictions on adding new payees, security experts say.
Check bank balances and scheduled payments at the end of every workday, rather than the beginning, and immediately contact your bank if anything is amiss. Banks use the Automated Clearing House system to transfer funds to payees’ banks. These transfers usually aren’t paid until the next morning, so timely action could halt the completion of a fraudulent transaction, Mr. Nelson says.
Shop for a Bank
Review your agreement with your bank and know what rights you may be waiving by not using certain security measures. While agreements between banks and commercial customers typically absolve banks of responsibility for fraud losses, the bank down the street may offer better protections, so shop around. Also, consider adding insurance coverage for fraud losses.
Many banks, concerned about damage to customer relationships, have stepped up their defenses against cyberattacks, rolled out new protections for customers and begun sharing more threat information with each other and law enforcement, Mr. Nelson says.
An emerging motivator may be a growing number of lawsuits by small companies claiming their banks didn’t have “commercially reasonable” security.
A judge in a closely watched case involving a self-employed couple’s personal and commercial accounts said in refusing to grant a summary judgment that a jury might find fault with the adequacy of the bank’s defenses, which the plaintiffs argued weren’t state of the art at the time of the theft. The case—Shames-Yeakel vs. Citizens Financial Bank—was settled in late December under confidential terms. The plaintiff’s lawyer, John Soumilas of Francis & Mailman PC in Philadelphia, says he pursued the case as one of consumer-identify theft, where protections are ample.
Still, David D. Johnson, a digital-media lawyer at Jeffer, Mangels, Butler & Marmaro LLP in Los Angeles who wasn’t involved in the case, says the judge’s action suggests that “a bank can’t simply rest on its laurels, on its security measures that worked last year,” and avoid liability. The judge declined to comment, and Citizens Financial didn’t return a call for comment.
Reach Out
Connect with law-enforcement agencies before an incident occurs, suggests Mr. Henry. He says small businesses should consider joining the FBI’s InfraGard, a group of businesses, academic institutions and state and local law-enforcement agencies that seek to ward off cyberattacks and other threats by sharing information and intelligence.
He also urges companies to report all computer crimes immediately to the FBI. The agency has relationships with law-enforcement organizations around the world that are starting to bear fruit, he says, pointing to the recent arrest of 120 people tied to Romanian groups that allegedly stole money from U.S. companies and citizens.
“In the cases where we have put hands on somebody, it was the result of a victim company raising their hand and saying this happened,” Mr. Henry says. “If they hit you today, they’re hitting the guy down the street tomorrow.”
Steganography is the means of “hiding” information within a larger file of data It poses a risk to ecommerce security because it allows data or malicious programming instructions to be hidden in other media. In the case of the former, malicious insiders (i.e. employees, contractors, etc) with access to customers financial data may improperly access that data and use steganography to forward it to their accomplices without being detected. In the case of the latter, hackers can embed malicious code in other files, such as images, audio and video files. These files can be forwarded to users as spam or made available via web sites and peer-to-peer networks in the guise of items that would attract the interest of web surfers.
