NYPD Testing New 'Skim Reaper' Device To Detect Credit Card Skimmers
NEW YORK (CBSNewYork/AP) – The NYPD is testing a new device, called the "Skim Reaper," that's designed to detect if an ATM or gas pump has been tampered with.
Credit card skimmers steal more than $1 billion from U.S. customers each year, according to the Secret Service. That money often funds organized crime.
The NYPD has four full-time, trained detectives tasked with finding skimmers installed on ATMs at bodegas, but says the problem is too widespread to be stopped with those resources.
"The problem is that it's transient, they come in and place the device and move on. In early January we were getting killed," Deputy Inspector Christopher Flanagan of the NYPD Financial Crimes Task Force said, referring to a January spike in skimming-related crimes.
In February, cyber security expert Patrick Traynor was working with police to find a way to detect the skimmers when he got a financial fraud alert: his own information had been stolen while he was in town.
It wasn't the first time. In five years he'd had his personal information stolen by credit card skimmers — devices illegally installed on ATMs and gas station pumps that "skim" consumer credit card numbers — a half-dozen times.
"I've got 15 years of experience in the field of information security. If I can't protect myself reliably, who else possibly can?" said Traynor, a computer information science and engineering professor at University of Florida.

After three years of study, Traynor and two Florida graduate students invented a device they call the "Skim Reaper," a credit-card thin gadget that slides into card reader slots and can easily and quickly detect if an ATM or gas pump has been compromised. The NYPD is now testing the device, with some early success, in its effort to rid the streets of the pervasive skimmers.
The Associated Press was given exclusive access to the lab where the Skim Reaper was made, as well as NYPD tests of it in the field.
Most credit card skimmers work by installing an extra "read head" inside or outside a machine. This extra read head allows criminals to make a copy of the card's information as a consumer swipes it. Skim Reaper was built to detect when more than one read head is present, Traynor said.
Traynor gave NYPD five Skim Reapers to test in February. The device looks like a long credit card that can be slid into a card slot in a gas pump or ATM. It's attached by a wire to a cellphone-sized box with a small readout screen that says "possible skimmer!" when multiple read heads are detected.
Part of the attraction to the Skim Reaper is its simplicity. Flanagan said officers in New York recently found the first skimmer using the device at an ATM in Brooklyn.
"I've been doing skimming for approximately five years now and I have never used anything like this or have known of anything like this," said NYPD Det. James Lilla of the Financial Crimes Taskforce. "It's definitely an assist we can use to combat ATM skimming."
The advent of debit and credit cards with protective chips that inserted into special readers have helped some retail businesses combat skimming. But the higher cost of the new readers and complexity of switching over to a new technology has been an obstacle for small retail businesses and gas stations where criminals have flourished.

Steven Weisman, a cybersecurity expert and professor at Bentley University in Massachusetts, said the Skim Reaper could be a "revolutionary, watershed moment" in the battle against skimmers.
"If indeed this new technology could be done on a cost effective basis, it could put the skimmers out of business. It would save people tremendous amounts of money and aggravation," Weisman said.
Right now, it costs about $50 to make each Skim Reaper, Traynor said, but his team is working daily to get that number down.
In New York, NYPD's Flanagan said more testing needs to be done but he is impressed with early results. Mainly, it allows untrained officers to be employed in the anti-skimming effort, where before trained investigators were needed to identify the illegal devices.
"I have four detectives who do the ATM skimming full time," he said. "They're all extremely busy with the amount of work we do, so when I can take someone who is untrained, or has some more free time to go out and do these inspections, it certainly is a help."
Nolen Scaife, one of the graduate students who designed the device with Traynor, said the team is working to improve the Skim Reaper's design so that it is wallet-sized. Then, consumers would be able to carry the device and dip it into a card reader before they get gas or use the ATM to ensure they aren't being skimmed.
"There's no greater feeling than feeling the work you're doing has wide-ranging impact," Scaife said. "We're glad to be able to produce something that will curb the tide."
