Software Taxonomy of Faults

Category Option Rationale
Recurring unknown The articles do not provide information about the software failure incident happening again at either the same organization or at multiple organizations. Therefore, the answer to this question is 'unknown'.
Phase (Design/Operation) design, operation (a) The software failure incident in the article can be attributed to the design phase. The incident involved a malicious app named 'Advanced Battery Saver' that was distributed via the Google Play Store. The app was designed to trick users by displaying a pop-up message customized to the exact make and model of their smartphone, urging them to install a cleanup app to prevent battery slowdown. However, upon installation, users were redirected to download malware that could steal personal data and even lead to potential blackmail [73624]. (b) The software failure incident can also be linked to the operation phase. Users who fell victim to the scam by downloading the malicious app were advised to delete the app and run anti-virus software on their Android devices to eradicate its effects. This highlights the operational aspect of dealing with the aftermath of the software failure incident caused by the malicious app [73624].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident in this case was within the system. The incident involved a malicious app called 'Advanced Battery Saver' that was distributed via the Google Play Store. The app, disguised as a battery-saving tool, was designed to steal personal data from users' smartphones, including sensitive information like location, phone numbers, and messages. The malware also ran an ad-clicker in the background to generate revenue for the fraudsters. The failure originated from within the system as the app itself was malicious and designed to deceive users [73624]. (b) outside_system: The software failure incident was also influenced by factors outside the system. The malware was distributed through a deceptive pop-up message that appeared while users were browsing online. This pop-up message, customized to the specific make and model of the user's smartphone, tricked users into believing that a memory cleanup was necessary to prevent battery slowdown. By clicking on the install button in the pop-up, users were redirected to the Google Play Store to download the malicious app. This external factor of a deceptive pop-up message played a role in luring users into downloading the malware [73624].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in the article was primarily due to non-human actions. The incident involved a malicious app named 'Advanced Battery Saver' that was distributed via the Google Play Store. This app, once installed, accessed users' personal data and ran an ad-clicker in the background to generate money for fraudsters. The malware was designed to steal information from the phone, including IMEI, phone numbers, phone type/brand/model, location, and more. The app was able to carry out these actions without direct human participation, making it a non-human action-related failure incident [73624]. (b) Additionally, human actions played a role in this software failure incident. Users were tricked into installing the malicious app through a pop-up message that appeared while browsing online. The message warned users about a 'cleanup' needed for their handset's memory to prevent battery slowing, prompting them to install the fraudulent app recommended by the pop-up. This action by users led to the installation of the malware, showcasing how human actions contributed to the failure incident [73624].
Dimension (Hardware/Software) hardware, software (a) The software failure incident in the article is related to hardware as it involves a malicious app, 'Advanced Battery Saver,' that was distributed via the Google Play Store and accessed personal data on Android smartphones [73624].
