Their aim was to gain access to transactions by VISA customers in Europe, the Middle East and Africa, according to one presentation. The goal was to "collect, parse and ingest transactional data for priority credit card associations, focusing on priority geographic regions."
In response to a SPIEGEL inquiry, however, VISA issued a statement in which it said, "We are not aware of any unauthorized access to our network. Visa takes data security seriously and, in response to any attempted intrusion, we would pursue all available remedies to the fullest extent of the law. Further, its Visa's policy to only provide transaction information in response to a subpoena or other valid legal process."
The NSA's Tracfin data bank also contained data from the Brussels-based Society for Worldwide Interbank Financial Telecommunication (SWIFT), a network used by thousands of banks to send transaction information securely. SWIFT was named as a "target," according to the documents, which also show that the NSA spied on the organization on several levels, involving, among others, the agency's "tailored access operations" division. One of the ways the agency accessed the data included reading "SWIFT printer traffic from numerous banks," the documents show.
