Inside Target Corp., Days After 2013 Breach

September 21, 2015

In December 2013, just days after a data breach exposed 40 million customer debit and credit card accounts, Target Corp. hired security experts at Verizon to probe its networks for weaknesses.

In the previous two stories, I documented the damage wrought by an organized crime gang in Mexico that has been systematically bribing ATM technicians to install Bluetooth skimming components that allow thieves to steal card and PIN data wirelessly. What follows is a look at a mysterious new ATM company in Mexico that sources say may be tied to the skimming activity.

I spent four days last week in Mexico, tracking the damage wrought by an organized crime ring that is bribing ATM technicians to place Bluetooth skimmers inside of cash machines in and around the tourist areas of Cancun. Today’s piece chronicles the work of this gang in coastal regions farther south, following a trail of hacked ATMs from Playa Del Camen down to the ancient Mayan ruins in Tulum.

-Sept. 9, 12:30 p.m. CT, Yucatan Peninsula, Mexico: Halfway down the southbound four-lane highway from Cancun to the ancient ruins in Tulum, traffic inexplicably slowed to a halt. There was some sort of checkpoint ahead by the Mexican Federal Police. I began to wonder whether it was a good idea to have brought along the ATM skimmer instead of leaving it in the hotel safe. If the cops searched my stuff, how could I explain having ultra-sophisticated Bluetooth ATM skimmer components in my backpack?

Last month, KrebsOnSecurity posted an exclusive story about emails leaked from AshleyMadison that suggested the company’s former chief technology officer Raja Bhatia hacked into a rival firm in 2012.

Microsoft today released a dozen security updates for computers running supported versions of its Windows operating system. Five of the patches fix flaws that could get PCs compromised with little to no help from users, and five of the bulletins have vulnerabilities that were publicly disclosed before today (including one has been detected in exploits in the wild). Separately, Adobe is pushing a security update for its Shockwave Player – a browser plugin that I’ve long urged readers to junk.

Most of us know to keep our guard up when withdrawing cash from an ATM and to look for any signs that the machine may have been tampered with. But ATM fraud experts say they continue to see criminal innovations with “insert skimmers,” wafer-thin data theft devices that fit inside the ATM’s card acceptance slot and do not alter the outward appearance of a compromised cash machine.

OPM (Mis)Spends $133M on Credit Monitoring

The Office of Personnel Management (OPM) has awarded a $133 million contract to a private firm in an effort to provide credit monitoring services for three years to nearly 22 million people who had their Social Security numbers and other sensitive data stolen by cybercriminals. But perhaps the agency should be offering the option to pay for the cost that victims may incur in “freezing” their credit files, a much more effective way of preventing identity theft.

A recent Reuters story accusing Russian security firm Kaspersky Lab of faking malware to harm rivals prompted denials from the company’s eponymous chief executive — Eugene Kaspersky — who called the story “complete BS” and noted that his firm was a victim of such activity. But according to interviews with the CEO of Dr.Web — Kaspersky’s main competitor in Russia — both companies experimented with ways to expose antivirus vendors who blindly accepted malware intelligence shared by rival firms.
