When Identity Thieves Hack Your Accountant

The Internal Revenue Service has been urging tax preparation firms to step up their cybersecurity efforts this year, warning that identity thieves and hackers increasingly are targeting certified public accountants (CPAs) in a bid to siphon oodles of sensitive personal and financial data on taxpayers. This is the story of a CPA in New Jersey whose compromise by malware led to identity theft and phony tax refund requests filed on behalf of his clients.

IRS Scam Leverages Hacked Tax Preparers, Client Bank Accounts

Identity thieves who specialize in tax refund fraud have been busy of late hacking online accounts at multiple tax preparation firms, using them to file phony refund requests. Once the Internal Revenue Service processes the return and deposits money into bank accounts of the hacked firms’ clients, the crooks contact those clients posing as a collection agency and demand that the money be “returned.”

In one version of the scam, criminals are pretending to be debt collection agency officials acting on behalf of the IRS. They’ll call taxpayers who’ve had fraudulent tax refunds deposited into their bank accounts, claim the refund was deposited in error, and threaten recipients with criminal charges if they fail to forward the money to the collection agency.

This is exactly what happened to a number of customers at a half dozen banks in Oklahoma earlier this month. Elaine Dodd, executive vice president of the fraud division at the Oklahoma Bankers Association, said many financial institutions in the Oklahoma City area had “a good number of customers” who had large sums deposited into their bank accounts at the same time.

File Your Taxes Before Scammers Do It For You

Today, Jan. 29, is officially the first day of the 2018 tax-filing season, also known as the day that fraudsters start requesting phony tax refunds in the names of identity theft victims. Want to minimize the chances of getting hit by tax refund fraud this year? File your taxes before the bad guys can!

Tax refund fraud affects hundreds of thousands, if not millions, of U.S. citizens annually. Victims usually first learn of the crime after having their returns rejected because scammers beat them to it. Even those who are not required to file a return can be victims of refund fraud, as can those who are not actually due a refund from the IRS.

Registered at SSA.GOV? Good for You, But Keep Your Guard Up

KrebsOnSecurity has long warned readers to plant your own flag at the my Social Security online portal of the U.S. Social Security Administration (SSA) — even if you are not yet drawing benefits from the agency — because identity thieves have been registering accounts in peoples’ names and siphoning retirement and/or disability funds. This is the story of a Midwest couple that took all the right precautions and still got hit by ID thieves who impersonated them to the SSA directly over the phone.
In mid-December 2017 this author heard from Ed Eckenstein, a longtime reader in Oklahoma whose wife Ruth had just received a snail mail letter from the SSA about successfully applying to withdraw benefits. The letter confirmed she’d requested a one-time transfer of more than $11,000 from her SSA account. The couple said they were perplexed because both previously had taken my advice and registered accounts with MySocialSecurity, even though Ruth had not yet chosen to start receiving SSA benefits.

Name+DOB+SSN=FAFSA Data Gold Mine

KrebsOnSecurity has sought to call attention to online services which expose sensitive consumer data if the user knows a handful of static details about a person that are broadly for sale in the cybercrime underground, such as name, date of birth, and Social Security Number. Perhaps the most eye-opening example of this is on display at fafsa.ed.gov, the Web site set up by the U.S. Department of Education for anyone interested in applying for federal student financial aid.

Fear Not: You, Too, Are a Cybercrime Victim!

Maybe you’ve been feeling left out because you weren’t among the lucky few hundred million or billion who had their personal information stolen in either the Equifax or Yahoo! breaches. Well buck up, camper: Both companies took steps to make you feel better today.

Yahoo! announced that, our bad!: It wasn’t just one billion users who had their account information filched in its record-breaking 2013 data breach. It was more like three billion (read: all) users. Meanwhile, big three credit bureau Equifax added 2.5 million more victims to its roster of 143 million Americans who had their Social Security numbers and other personal data filched in a breach earlier this year. At the same time, Equifax’s erstwhile CEO informed Congress that the breach was the result of even more bone-headed security than was first disclosed.

To those still feeling left out by either company after this spate of news, I have only one thing to say (although I feel a bit like a broken record in repeating this): Assume you’re compromised, and take steps accordingly.

IRS: Scam Blends CEO Fraud, W-2 Phishing

Most regular readers here are familiar with CEO fraud — e-mail scams in which the attacker spoofs the boss and tricks an employee at the organization into wiring funds to the fraudster. Loyal readers also have heard an earful about W-2 phishing, in which crooks impersonate the boss and request a copy of all employee tax forms. According to a new “urgent alert” issued by the U.S. Internal Revenue Service, scammers are now combining both schemes and targeting a far broader range of organizations than ever before.

IRS Re-Enables ‘Get Transcript’ Feature

The Internal Revenue Service has re-enabled a service on its Web site that allows taxpayers to get a copy of their previous year’s tax transcript. The renewed effort to beef up taxpayer authentication methods at irs.gov comes more than a year after the agency disabled the transcript service because tax refund fraudsters were using it to steal sensitive data on consumers.

Fraudsters Steal Tax, Salary Data From ADP

Identity thieves stole tax and salary data from payroll giant ADP by registering accounts in the names of employees at more than a dozen customer firms, KrebsOnSecurity has learned. ADP says the incidents occurred because the victim companies all mistakenly published sensitive ADP account information online that made those firms easy targets for tax fraudsters.

IRS Suspends Insecure ‘Get IP PIN’ Feature

Citing ongoing security concerns, the Internal Revenue Service (IRS) has suspended a service offered via its Web site that allowed taxpayers to retrieve so-called IP Protection PINs (IP PINs), codes that the IRS has assigned to some 2.7 million taxpayers to help prevent those individuals from becoming victims of tax refund fraud two years in a row. The move comes just days after KrebsOnSecurity first exposed how ID thieves were abusing the service to revisit tax refund on innocent taxpayers two years running.
