Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident of a data breach due to hackers stealing unencrypted user data has happened again within the same organization, Cupid Media. The incident occurred in January 2013, where up to 42 million users' names, dates of birth, email addresses, and passwords were stolen [23062]. Cupid Media did not admit to the breach until it was exposed by security researcher Brian Krebs. The company stored user data in plain text, similar to the breach that occurred at Adobe, which used some encryption on the data. Cupid Media's managing director admitted to the breach and mentioned taking actions to notify affected customers and reset passwords for a particular group of user accounts. The company has since started encrypting passwords using techniques called salting and hashing to enhance security measures [23062]. (b) The software failure incident of a data breach due to hackers stealing unencrypted user data has also occurred at other organizations. The article mentions that Adobe had disclosed a breach earlier in November, where user information was stolen from their servers. Unlike Cupid Media, Adobe used some encryption on the data. The article highlights the importance of encryption in safeguarding sensitive data and mentions that many companies shy away from encryption due to perceived cost or complexity, despite its effectiveness in preventing data theft [23062].
Phase (Design/Operation) design, operation (a) The software failure incident described in the article is primarily related to the design phase. The incident occurred due to the lack of encryption of user data by Cupid Media, which runs niche online dating sites. The company stored user data, including passwords, in plain text, making it vulnerable to hackers who were able to steal up to 42 million users' unencrypted information [23062]. (b) The software failure incident is also related to the operation phase. Cupid Media's failure to encrypt user data and the misuse of sensitive information by hackers during the operation of the system led to the data breach. Additionally, the company's response to the breach, such as only notifying active users and not taking adequate security measures initially, contributed to the operational failure aspect of the incident [23062].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident involving the hacking of Cupid Media's user data was primarily due to factors originating from within the system. Cupid Media stored user data, including passwords, in plain text without encryption, making it vulnerable to hacking [23062]. The company only notified active users affected by the breach, neglecting to inform inactive, disabled, and test accounts, similar to Adobe's approach [23062]. Cupid Media started encrypting passwords using salting and hashing techniques after the breach to enhance security [23062]. (b) outside_system: The software failure incident also involved contributing factors originating from outside the system, specifically the actions of hackers who broke into Cupid Media's system to steal user data [23062].
