Security in Digital Payments: Inside the Mind of the Attacker

Presented at ekoparty 14 (2018), Sept. 27, 2018, 1:50 p.m. (120 minutes)

Currently, physical and digital payment systems that use technologies such as NFC or MST change constantly, Adding to this, new technologies that in a preventive way can help to restrain certain attacks; at the same time they open new breaches that are used by attackers in a colateral way. The workshop´s aim is to help people understand and to prevent real threats that may face any type of institution that handles digital and physical payments. The power of detecting and informing properly these attacks, understanding the logic, what areas may be exploited and what devices are implemented. During the workshop, a critical analysis of the mind of an attacker will be revealed, as well as attacks or extraction of data never documented before by using technologies and exploiting the weak design in which current payments fall.
