First ‘Jackpotting’ Attacks Hit U.S. ATMs

January 27, 2018

ATM “jackpotting” — a sophisticated crime in which thieves install malicious software and/or hardware at ATMs that forces the machines to spit out huge volumes of cash on demand — has long been a threat for banks in Europe and Asia, yet these attacks somehow have eluded U.S. ATM operators. But all that changed this week after the U.S. Secret Service quietly began warning financial institutions that jackpotting attacks have now been spotted targeting cash machines here in the United States.

Anti-Skimmer Detector for Skimmer Scammers

December 5, 2017

Crooks who make and deploy ATM skimmers are constantly engaged in a cat-and-mouse game with financial institutions, which deploy a variety of technological measures designed to defeat skimming devices. The latest innovation aimed at tipping the scales in favor of skimmer thieves is a small, battery powered device that provides crooks a digital readout indicating whether an ATM likely includes digital anti-skimming technology.

Would You Use This ATM?

One basic tenet of computer security is this: If you can’t vouch for a networked thing’s physical security, you also cannot vouch for its cybersecurity. That’s because in most cases, networked things really aren’t designed to foil a skilled and determined attacker who can freely connect his own devices. So you can imagine my shock and horror seeing a Cisco switch and wireless antenna sitting exposed atop of an ATM out in front of a bustling grocery store in my hometown of Northern Virginia.

How to Spot Ingenico Self-Checkout Skimmers

June 24, 2016

A KrebsOnSecurity story last month about credit card skimmers found in self-checkout lanes at some Walmart locations got picked up by quite a few publications. Since then I’ve heard from several readers who work at retailers that use hundreds of thousands of these Ingenico credit card terminals across their stores, and all wanted to know the same thing: How could they tell if their self-checkout lanes were compromised? This post provides a few pointers.

ATM Insert Skimmers In Action

June 13, 2016

KrebsOnSecurity has featured several recent posts on “insert skimmers,” ATM skimming devices made to fit snugly and invisibly inside a cash machine’s card acceptance slot. I’m revisiting the subject again because I’ve recently acquired how-to videos produced by two different insert skimmer peddlers, and these silent movies show a great deal more than words can tell about how insert skimmers do their dirty work.

Mir Islam – the Guy the Govt Says Swatted My Home – to be Sentenced June 22

June 1, 2016

On March 14, 2013 our humble home in Annandale, Va. was “swatted” — that is to say, surrounded by a heavily-armed police force that was responding to fraudulent reports of a hostage situation at our residence. Later this month the government will sentence 21-year-old hacker named Mir Islam for that stunt and for leading a criminal conspiracy allegedly engaged in a pattern of swatting, identity theft and wire fraud.

A Dramatic Rise in ATM Skimming Attacks

April 29, 2016

Skimming attacks on ATMs increased at an alarming rate last year for both American and European banks and their customers, according to recent stats collected by fraud trackers. The trend appears to be continuing into 2016, with outbreaks of skimming activity visiting a much broader swath of the United States than in years past.

Skimmers Hijack ATM Network Cables

February 9, 2016

If you have ever walked up to an ATM to withdraw cash only to decide against it after noticing a telephone or ethernet cord snaking from behind the machine to a jack in the wall, your paranoia may not have been misplaced: ATM maker NCR is warning about skimming attacks that involve keypad overlays, hidden cameras and skimming devices plugged into the ATM network cables to intercept customer card data.
