Move over, ID theft — here’s the new No. 1 fraud

(CBS MONEYWATCH) Beware of bogus IRS agents, fake offers of tech support and faux beaus — in other words, impostors. They’ve overtaken identity thieves to become the nation’s top fraudsters, according to the latest consumer complaint data.

The Federal Trade Commission’s Consumer Sentinel project, which tallies up the number and type of consumer complaints received each year, reported more than 3 million of them in 2016. Debt collection remains the No. 1 gripe, accounting for some 28 percent of reported complaints. However, the bulk of debt-collection complaints involve overly aggressive collection tactics, not fraud.

When it comes to consumer frauds, impostor scams are now leading the list, having leapfrogged ID theft for the first time since the government started keeping records in 1997. Notably, these frauds can be devastatingly costly. Although not all consumers report their losses, those that did got taken for $744.5 million in total, with the average loss weighing in at $1,124, government officials said.

“We are very troubled by the impostor scams both because of the growth and because the many involve [crooks] using the names of government agencies to get money out of people,” said Monica Vaca, acting associate director in the Division of Consumer Response and Operations at the Federal Trade Commission.

The FTC said it’s trying to hunt down these criminals through law enforcement and to educate consumers about the warning signs to prevent victims from losing more money.

What are the most pernicious types of impostor scams, and how can you spot them?

IRS scam

Phony IRS agents reach you by phone, email or text message claiming you owe money. Threatening to take legal action, they urge you to send payment by money order, cashier’s check or prepaid debit card immediately — in some cases, insisting that you complete the transaction while you’re still on the phone.

How you know it’s a scam: A legitimate IRS agent will always first contact you by mail, and the agency accepts checks and credit card payments. The IRS never insists on swift payment by debit card, cashier’s check or wire transfer.

Tech support scams

The phone rings, and the caller claims to be a Microsoft or Apple tech support representative who has detected a problem with your computer. He or she urges you to visit a particular site, or type a series of keys into your computer, to give the fake support person the ability to control the machine and “fix” whatever is wrong.

Alternatively, a popup window appears on your screen, warning that your system isn’t secure and you must download security software by clicking on a link in the popup immediately. In both cases, the scammer is aiming to download malicious software onto your machine to either steal your data or to hold your machine hostage until you pay some sort of ransom.

How you know it’s a scam: Real tech support departments don’t call you out of the blue nor can they detect problems you haven’t reported. And while you do need security software for your computer, you’re not going to find it by clicking on a popup ad. Most computers come with security software. All that’s necessary to keep yours up to date is to renew your annual subscription.

Grandkid scams

Con artists buy marketing lists, just like big retailers do, looking for vulnerable populations to exploit. The elderly are a particularly ripe target, with those over age 60 accounting for roughly 37 percent of fraud victims.

One common scam exploits grandparents by having a con artist pose as a young relative, who then maintains he’s out of town and in trouble. Pleading with the grandparent not to tell anyone, the fake grandchild contends that the only way to get out of this bind is for the grandparent to send money via wire transfer.

How you know it’s a scam: A quick phone call or text message to your real relative is likely to find him/her at home. Not sure? Tell the caller that you’ll have to call back. If the grandchild contends that’s not possible, you know you’re talking to a crook. These scammers use a sense of urgency to get you to send cash before you can check out the story. Rest assured, even Mexican jails have phones.

Online romance scams

Ever sign up for a dating site? Then you’re a prime target for a romance scam, where a distant lover strikes up a conversation and quickly becomes besotted. Claiming that you’re the man/woman of his/her dreams, this faux lover will say he/she would love to meet in person but is (a) out of town on business (b) stationed abroad in the military (c) living in another country or (d) hampered by a sick or dying relative. Once the faux beau is convinced that you’re hooked, the requests for money start.

Typically, the con artist will contend that some emergency has left him/her desperately short of cash and in need of your help. Sometimes, the con artist pretends the only thing that keeps him/her from showing up on your doorstep is that he/she is short of the money to get there.

Of course, if the victim provides cash, another emergency will require more. The fake romance ends when the victim stops sending money.

How you know it’s a scam: If someone claims to be madly in love you with you, even though you’ve never met, it should raise a red flag. If the person has a litany of excuses of why you can’t meet in person, it’s almost assuredly a con. All you need for a final confirmation is to wait for the request for money.

Outside of romance scams, which are initiated and often pursued completely online, some 77 percent of impostors approach their victims via phone, federal officials say. One way to thwart these attempts is to let unknown callers go to your answering machine. Con artists rarely leave a message. You can also use services like Nomorobo or Hiya to block so-called robo-calls — machine-dialed calls that crooks typically use.

Additionally, the type of payment you’re asked to provide can also serve as a warning. Government officials said 58 percent of victims said they paid via wire transfer in 2016. Prepaid debit cards are also popular with scammers because these payments are untraceable and impossible to reverse. If you paid a crook by credit card, on the other hand, you can dispute the charge and likely get your money back.
