(b) There is no specific information in the provided article about a similar incident happening at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase: The Twitch data breach incident can be attributed to a failure in the design phase of the system. The breach exposed sensitive data, including Twitch's entire source code and payout information of popular streamers, indicating a significant security flaw in the system's design [Article 120023]. (b) The software failure incident related to the operation phase: The Twitch data breach incident can also be linked to a failure in the operation phase of the system. The breach was a result of a targeted attack that successfully exfiltrated 125GB of sensitive data without triggering any alarms, suggesting a failure in the operational security measures of the platform [Article 120023].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident of the Twitch data breach was primarily due to a highly targeted attack on the Twitch platform itself. The breach resulted in the exposure of sensitive data, including Twitch's source code and payout information of popular streamers. The breach was a result of hackers gaining unauthorized access to Twitch's internal systems and exfiltrating a large trove of data [Article 120023]. (b) outside_system: The software failure incident also involved external factors, such as the hacker who carried out the attack with the intention of fostering disruption and competition in the online video streaming space. Additionally, the breach could have implications for Twitch's popularity and user trust, leading to a surge in online queries on how to delete Twitch following the breach. This external response indicates the impact of the breach on users and the broader online community [Article 120023].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in this case was primarily due to non-human actions, specifically a highly targeted hack on the Amazon-owned gaming platform Twitch. The breach resulted in the exposure of sensitive data, including Twitch's entire source code and payout information of popular streamers [Article 120023]. (b) Human actions also played a role in this software failure incident as the hacker behind the breach carried out the attack to "foster more disruption and competition in the online video streaming space" [Article 120023]. Additionally, the article mentions the possibility of hackers using phishing campaigns to obtain employee credentials and gain access to sensitive data, highlighting the role of human actions in contributing to the breach [Article 120023].
Dimension (Hardware/Software) software (a) The software failure incident reported in the article is not attributed to hardware issues. The incident is primarily described as a data breach and hack targeting the Amazon-owned gaming platform Twitch, resulting in the exposure of sensitive data such as source code and payout information of streamers [Article 120023]. (b) The software failure incident is directly linked to software-related factors, specifically a data breach and hack targeting Twitch's platform. The breach resulted in the unauthorized access and exfiltration of sensitive data, including source code and payout information, indicating a failure originating in the software security measures of the platform [Article 120023].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident related to the Twitch data breach is malicious in nature. The breach was described as a "highly targeted attack" by experts [Article 120023]. The hacker behind the breach posted the leaked data online with the intention to "foster more disruption and competition in the online video streaming space" [Article 120023]. The breach involved exfiltrating sensitive data, including Twitch's entire source code and payout information of popular streamers, indicating a deliberate attempt to harm the system and cause disruption.

(b) The software failure incident related to accidental factors is not explicitly mentioned in the articles provided.
Duration temporary The software failure incident reported in the article about the Twitch data breach can be categorized as a temporary failure. This incident was a result of a highly targeted attack by a hacker who managed to exfiltrate sensitive data, including Twitch's source code and payout information on streamers. The breach was not a permanent failure but rather a temporary one caused by specific circumstances, such as the hacker's actions and the vulnerabilities they exploited in Twitch's systems [Article 120023].
Behaviour other (a) crash: The software failure incident in the Twitch data breach incident did not involve a crash where the system loses state and does not perform any of its intended functions. The breach involved the exfiltration of sensitive data, including Twitch's source code and payout information, indicating a targeted attack rather than a system crash [Article 120023]. (b) omission: The incident did not involve a failure due to the system omitting to perform its intended functions at an instance(s). Instead, the breach was a result of a targeted attack that successfully exfiltrated sensitive data from Twitch's platform [Article 120023]. (c) timing: The software failure incident was not related to timing issues where the system performs its intended functions correctly but too late or too early. The breach involved the unauthorized access and exfiltration of sensitive data, indicating a security breach rather than a timing issue [Article 120023]. (d) value: The failure in the Twitch data breach incident was not due to the system performing its intended functions incorrectly.
