Pursuit of “good customers’ experience“ not only leads to new customers, but also attract criminals of all sorts. Presentation will give overview of current security situation of ATMs with different auxiliary devices allowing cardless transactions. Cardless is new sexy for criminals.

Era of ATMs has started in London in 1967. Since time, when the “hole-in-the-wall” cash machine used radiocarbon paper cheques, ATMs became more complex and smart, providing opportunity to withdraw money without cards. Vendors, in accordance to banks and consumer’s demand, create ATMs that replace plastic cards and PINs with smartphones or QR codes. Cash withdrawal from an ATM now easier than never before not only for clients, but also for attackers. Jackpotting an ATM via malware or black box are pretty familiar. Countermeasures against such attacks are already in place in many banks. Thus, attackers need to discover new (or well-forgotten) ways to achieve their evil goals. We will not chew the fat, telling stories about the old days, because new functionality provides new possibilities. Migration from Windows XP to Windows 7/10 means there is always PowerShell on the ATM. “New” types of input devices allow BadBarcode-like attacks. Legitimate auxiliary device connected to the ATM in pursuit of so-called good customers’ experience may lead to ejection of all money from ATM.

How to stop the ATMs fraud? How to protect ATMs from attacks such as black box jackpotting? How to prevent network hijacking such as rogue processing center or MiTM? Some of these issues can be fixed by configuration means, some fixed by compensation measures, but many only by vendor. We will tell you about what bank can do now and what we as a community of security specialists should force to vendors.

Guys with malicious intentions never sleep, but make their bad deal all days, all nights. When you have your five-o-clock beer, they open service zone of ATM and connect "magic box" that make ATM empty. Alternatively, sometimes banks security guys may watch video surveillance footage with man-in-the-hoody, who make something in the nearby corner of ATM. Surely, ATM is empty again! On the other hand, banks may not have any video monitoring so they cannot imagine how ATM became empty without any forensics evidence. We have collected huge number of cases on how ATMs could be hacked during our researches, incidents responses and security assessments. A lot of malware infects ATM through the network or locally. There are black boxes, which connect to communications port of devices directly. There are also network attacks, such as rogue processing center or MiTM. Before we spoke about vulnerabilities and fraud methods used by criminals. Now we would like to combine our expertise to help financial and security society with more direct advices how to implement security measures or approaches to make ATMs more secure.
