The incident involved the exposure of vulnerabilities in Cisco's networking appliances due to stolen data from the NSA hacking team, as reported by Shadow Brokers [46969]. This incident is reminiscent of a previous incident in 2014 when Edward Snowden's leaks revealed that the NSA was intercepting shipments of Cisco's equipment to install spyware, leading to concerns raised by Cisco's then-CEO John Chambers about compromising the company's business [46969]. (b) The software failure incident involving the exposure of vulnerabilities in networking equipment from multiple organizations was not explicitly mentioned in the articles.
Phase (Design/Operation) design (a) The software failure incident discussed in the articles is related to the design phase. The incident involves the NSA's dilemma of whether to report security flaws it discovers in software and hardware to the product's manufacturer or keep them secret for offensive purposes. The leaked data from the NSA hacking team, which contained exploits targeting networking appliances from companies like Cisco and Fortinet, highlights the risks associated with keeping zero-day vulnerabilities secret. The incident raises questions about the NSA's practice of hoarding zero days and not disclosing them to vendors, potentially leading to the exploitation of these vulnerabilities by unauthorized entities [46969]. (b) The software failure incident is not directly related to the operation phase or misuse of the system.
Boundary (Internal/External) within_system, outside_system The software failure incident reported in the articles can be categorized as both within_system and outside_system: (a) within_system: The failure within the system is evident from the fact that the NSA's secret hacking tools, including zero-day exploits, were stolen and leaked by a group known as Shadow Brokers [46969]. This indicates a failure within the NSA's internal security measures and practices, leading to the compromise of sensitive hacking techniques and tools. (b) outside_system: On the other hand, the failure can also be attributed to factors outside the system, particularly the actions of external threat actors like Shadow Brokers who were able to breach the NSA's security and steal the classified data [46969]. This external breach highlights vulnerabilities in the overall cybersecurity ecosystem and the risks associated with sophisticated cyberattacks targeting government agencies and their sensitive information.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in this case can be attributed to non-human actions, specifically the exploitation of zero-day vulnerabilities by the NSA for hacking purposes. The leaked data containing hacking tools and exploits, which were kept secret by the NSA, fell into the hands of an anonymous group known as Shadow Brokers [46969]. (b) On the other hand, human actions also played a significant role in this software failure incident. The decision by the NSA to keep zero-day vulnerabilities secret rather than reporting them to affected companies contributed to the vulnerability of various networking appliances from companies like Cisco and Fortinet. This decision-making process regarding the disclosure of vulnerabilities highlights the human factor in the incident [46969].
