Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident related to the fake tech support scam for Netflix and Gmail has happened before within the same organization. The article mentions that the security scam claiming to offer technical support to Netflix and Gmail users involved hackers asking for personal information, charging for support calls, and attempting to take control of users' webcams [25431]. This indicates a recurring issue within the organization's services. (b) The software failure incident related to the fake tech support scam for Netflix and Gmail has also happened with other organizations. The article highlights that security experts have uncovered a new security scam targeting Netflix and Gmail users, indicating that similar incidents may have occurred with other organizations or services as well [25431].
Phase (Design/Operation) design, operation (a) The software failure incident in the article can be attributed to the design phase. The incident involved a fake tech support scam targeting Netflix and Gmail users, where hackers tricked users into calling a fake support number and downloading software that allowed remote control of their machines [25431]. This scam was designed to deceive users into thinking they were receiving legitimate technical support, highlighting a failure in the design of security measures to protect users from such fraudulent activities. (b) The software failure incident can also be linked to the operation phase. Users were misled into providing personal information, including usernames, passwords, and even allowing access to their webcams, under the guise of receiving technical support [25431]. This indicates a failure in the operation of the system, as users were manipulated into taking actions that compromised their security and privacy.
Boundary (Internal/External) within_system (a) within_system: The software failure incident described in the article is primarily within the system. The incident involved a phishing scam where users were tricked into providing their username and password, leading to the scammers gaining access to their machines. The scammers then asked users to download software that allowed them to remotely control the machines. Additionally, the scammers went through the users' personal files and attempted to charge them for fake tech support services. This failure originated from within the system as it involved exploiting vulnerabilities in the software and manipulating users to gain unauthorized access and control over their machines [25431].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in the article is primarily due to non-human actions. The incident involved a fake tech support scam targeting Netflix and Gmail users, where hackers tricked users into downloading software that allowed remote control of their machines and potentially compromising their personal information and webcam [25431]. The scam was initiated through phishing attacks and automated messages, with hackers manipulating software to gain unauthorized access and control over users' devices without direct human involvement in the software failure.
Dimension (Hardware/Software) hardware, software (a) The software failure incident in the article is primarily related to hardware. The incident involved a fake tech support scam where hackers gained control of users' machines and webcams by tricking them into downloading software that allowed remote access. This type of failure can be attributed to the hardware aspect of the users' machines, specifically the webcam and other components that were accessed and manipulated by the hackers [25431]. (b) The software failure incident in the article is also related to software. The scam involved phishing attacks that prompted users to enter their usernames and passwords, leading to the installation of software that allowed hackers to remotely control the machines. This software manipulation was a key aspect of the scam, indicating a failure originating in the software used by the hackers to exploit users' systems [25431].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident described in Article 25431 is malicious in nature. It involves a fake tech support scam where hackers deceive users into providing personal information, downloading software that allows remote control of their machines, and potentially taking control of their webcams. The hackers aim to gather sensitive information, make credit card charges for fake support services, and potentially exploit the users' data for malicious purposes. The incident demonstrates a deliberate attempt by individuals to harm users and exploit their trust in tech support services [25431].
Intent (Poor/Accidental Decisions) poor_decisions (a) The intent of the software failure incident: - The software failure incident described in the article was driven by poor decisions made by hackers who initiated a fake tech support scam targeting Netflix and Gmail users. - The hackers tricked users into providing their username and password, then instructed them to call a fake support number and download software that allowed remote control of their machines. - The scammers aimed to gather personal information, charge users up to $400 for fake tech support, and even attempted to access users' webcams to take pictures of IDs and credit cards. - This incident highlights the malicious intent behind the scam, showcasing a deliberate effort to deceive and exploit unsuspecting users for financial gain [25431].
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident in the article can be attributed to development incompetence. The incident involved scammers posing as fake tech support for Netflix and Gmail, tricking users into providing personal information and downloading software that allowed remote control of their machines [25431]. This demonstrates a lack of professional competence on the part of the scammers who exploited users' trust and lack of awareness to carry out their fraudulent activities. (b) The software failure incident can also be categorized as accidental. Users were lured into the scam through phishing emails and messages, leading them to unknowingly provide sensitive information and grant remote access to their machines [25431]. The accidental nature of this incident lies in the unsuspecting users falling victim to the scam without intending to do so, highlighting the deceptive tactics employed by the scammers.
Duration temporary The software failure incident described in the article [25431] can be categorized as a temporary failure. The incident involved a fake tech support scam targeting Netflix and Gmail users, where hackers tricked users into downloading software that allowed remote control of their machines. This incident was temporary as it was caused by specific circumstances introduced by the scam, such as users falling for the phishing attack, calling the fake support number, and downloading the malicious software. The failure was not permanent as it was not a result of inherent flaws in the software itself but rather the deceptive actions of the scammers.
Behaviour omission, value, other (a) crash: The software failure incident described in the article does not specifically mention a crash where the system loses state and stops performing its intended functions. (b) omission: The incident involves the system omitting to perform its intended functions at instances. Users were asked to call a fake support number, download software that allowed hackers to remotely control their machines, and provide personal information, leading to the omission of the system's actual support functions [25431]. (c) timing: The incident does not relate to timing issues where the system performs its intended functions but at the wrong time. (d) value: The failure in this incident can be categorized under the value option. The system performed its intended functions incorrectly by misleading users into believing they were receiving legitimate technical support for services like Netflix and Gmail, while in reality, they were being scammed for personal information and money [25431]. (e) byzantine: The behavior of the software failure incident does not align with a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. (f) other: The other behavior observed in this incident is deception and social engineering. The hackers deceived users by posing as legitimate support staff for Netflix and Gmail, tricking them into providing sensitive information and granting remote access to their machines under the guise of technical support [25431].
