WASHINGTON - Addicted as we are to our online life and our mobile devices, it's no surprise that a growing number of cybercriminals are lurking out there with us.
Their newest target is right in our hands: our cell phones.
Complaints of cybercrime topped 314,000 in 2011 -- up 3.4 percent from the prior year, according to a report issued Thursday by the Internet Crime Complaint Center, a partnership of the FBI, the National White Collar Crime Center and the U.S. Department of Justice.
Online crime occurs in varied forms, from identity theft that uses personal information to commit fraud, to phony job schemes involving bad check deposits, to "romance scams" that seduce the lovelorn to send money to a pseudo-suitor. Nationwide, the average victim who filed a complaint last year was duped out of $4,187, reported the Internet complaint center.
The FBI said the most common scams are identity theft, advance-fee and nondelivery scams. For instance, victims can be defrauded on Craigslist by sending money for items that never arrive or by applying for job offers that involve wire transfers of phony checks.
Cybercrime is thought to be a much larger problem than the numbers released Thursday suggest. Internet crime is "grossly underreported" nationally, said William Hinerman, the crime center's unit chief. "We know there are tens of millions of computer users in the United States, and everybody who gets email gets spam."
In announcing the annual Internet crime statistics, the center's deputy director, Ken Brooks, said he was excited by the increase in complaints because it means more Americans are aware of online crime and realize they have somewhere to report it.
California, the nation's most populous state, posted the highest total number of Internet crime complaints last year, with 34,169. Next came Florida, then Texas, New York and Ohio.
On a per-capita basis, however, California was No. 13 in the nation. Based on complaints per 100,000 population, the most fraud was reported in Alaska, the District of Columbia, New Jersey, Nevada and Colorado.
California ranked last in reported losses per 100,000 population, at $14.73. That compares with Washington, D.C., which was No. 1 with $1,119.70 in losses per 100,000 people.
While cybercrime has been around for years, the newest frontier for scam artists is mobile phones, the Internet crime center said.
It's fertile territory. According to a recent Pew survey, about 83 percent of U.S. adults have a cellphone. An estimated 42 percent of those have smartphones that can access email and the Internet.
Michael Parker, a retired rancher in Sacramento, Calif., has already seen cyber-thieves sneak onto his T-Mobile cellphone. Last month, he had two text messages, purportedly from Wal-Mart, declaring he'd "won" a $1,000 gift card. To claim his prize, he was instructed to click on a website.
Parker didn't bite. "Being a cynic helps," he said. "I'm not a Walmart shopper, so that was one tipoff it was a scam."
Instead of clicking on the link, he called a local Walmart manager to ask if the discount chain was giving out gift certificates by cellphone. The manager, Parker said, was "shocked, dismayed and not happy" to hear about the attempted scam, which likely was an attempt to install malware on Parker's computer or trick him into giving out bank account or other financial information.
Parker also reported the phony texts to the Sheriff's Department and signed up his cellphone for the national "Do Not Call" registry at www.donotcall.gov .
Romance scams proved especially lucrative for scammers last year, according to complaint center statistics. At a rate of 15 complaints a day, the scams saw reported losses of roughly $138,000, or more than $5,700 every hour. The average victim's loss: $8,900.
How can you protect yourself from being swindled? The FBI's Bryant said individuals should "never give out any personal or financial information over the phone or Internet, unless he or she has personally initiated the communication."
Do your homework to verify the source of any online offers or official-sounding requests for your personal account information. In general, be skeptical of anything that sounds too good to be true.
