(b) The software failure incident having happened again at multiple_organization: - The article mentions that in the digital arms race between authorities and hackers, corporations and security firms are struggling to keep pace, with 43% of US firms experiencing data breaches in the past year [32500]. - It also highlights that major cyber attacks are expected to cause widespread harm in the next 10 years, indicating a trend of such incidents across various organizations [32500].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the article where it mentions that hackers installed malware in the third party's point-of-sale (POS) software, which is a system development aspect, allowing them to steal data encoded on the back of cards [32500]. (b) The software failure incident related to the operation phase is evident in the article where it discusses the possibility of customers being affected by the breach and advises them to keep a close eye on bank and card statements to look out for suspicious activity and possible identity theft, which is related to the operation or misuse of the system [32500].
Boundary (Internal/External) within_system (a) within_system: The software failure incident at Chick-fil-A, involving a possible data breach in its payment system, was likely due to contributing factors that originated from within the system. The breach was suspected to have occurred through the installation of malware in the point-of-sale (POS) software used at the restaurant locations, allowing hackers to steal data encoded on the back of cards [32500].
Nature (Human/Non-human) non-human_actions (a) The software failure incident occurring due to non-human actions: - The software failure incident at Chick-fil-A was likely caused by hackers who installed malware in the third party's point-of-sale (POS) software, allowing them to steal data encoded on the back of cards [32500]. - The breach was compared to similar attacks on major US corporations like Home Depot and Target, where hackers installed malware on systems to compromise credit and debit card numbers [32500]. (b) The software failure incident occurring due to human actions: - The breach at Chick-fil-A was not directly caused by human actions but rather by hackers who exploited vulnerabilities in the POS software [32500]. - The article does not mention any specific human actions that directly led to the software failure incident at Chick-fil-A.
Dimension (Hardware/Software) software (a) The software failure incident related to hardware: - The article does not specifically mention any hardware-related issues contributing to the software failure incident at Chick-fil-A [32500]. (b) The software failure incident related to software: - The software failure incident at Chick-fil-A was attributed to a possible data breach involving the payment system at some of its restaurants [32500]. - Cybersecurity journalist Brian Krebs reported that financial institutions traced suspicious activity on cards to Chick-fil-A locations, indicating a breach in the point-of-sale (POS) software used by the company [32500]. - The breach was compared to similar incidents at other medium-sized chains where hackers installed malware in the POS software to steal data encoded on the back of cards [32500]. - The article highlights the ongoing digital arms race between authorities, hackers, corporations, and security firms, indicating the challenges in keeping pace with sophisticated cyber attacks [32500].
