| Category | Option | Rationale |
|---|---|---|
| Recurring | one_organization, multiple_organization | (a) The software failure incident related to the lack of encryption in Tinder's mobile apps has happened again at the same organization. Checkmarx researchers discovered vulnerabilities in Tinder's app in January 2018, where profile pictures were using an insecure HTTP connection instead of HTTPS, allowing hackers on the same Wi-Fi network to view and potentially replace images [67140, 72750, 67769]. (b) The software failure incident related to the lack of encryption in dating apps has also happened at other organizations. Match Group, the owner of Tinder, addressed security flaws discovered by Checkmarx researchers by encrypting images and swipes sent between Tinder's app and servers to prevent hackers from spying on user data [72750]. |
| Phase (Design/Operation) | design, operation | (a) The software failure incident related to the design phase: The incident reported in Article #67140 highlights a software failure due to design flaws in Tinder's mobile apps. Researchers at Checkmarx discovered that Tinder's mobile apps lacked basic HTTPS encryption for photos, allowing anyone on the same Wi-Fi network to view users' photos and even inject their own images into the photo stream. This vulnerability was a result of the lack of proper encryption in the design of the app, making sensitive user data easily accessible to potential hackers [67140]. (b) The software failure incident related to the operation phase: The incident reported in Article #67769 discusses a software failure in Tinder's security due to operational vulnerabilities. Checkmarx researchers found that due to the use of insecure HTTP connections for profile pictures, attackers on the same network could spy on users' internet traffic and view images, potentially even replacing them without the user's knowledge. Additionally, the encryption used for swipe data was not robust enough, allowing attackers to decipher user actions based on file sizes. These operational vulnerabilities exposed user data to potential exploitation, highlighting issues introduced during the operation of the app [67769]. |
| Boundary (Internal/External) | within_system | (a) within_system: The software failure incident in the articles is primarily due to contributing factors that originate from within the system. Specifically, the vulnerabilities in Tinder's mobile apps were identified by researchers at Checkmarx, a security company specializing in application security [67140, 72750, 67769]. These vulnerabilities included the lack of basic HTTPS encryption for photos, allowing anyone on the same Wi-Fi network to view photos, inject their own images, and monitor user interactions on the app. Additionally, flaws in the encryption of swipe data made it possible for hackers to discern users' actions [67140, 72750, 67769]. The issues were discovered in both the Android and iOS versions of Tinder, indicating internal weaknesses within the app's design and implementation. (b) outside_system: The software failure incident does not seem to be primarily caused by contributing factors originating from outside the system. While the vulnerabilities could be exploited by attackers on the same Wi-Fi network, the root cause of the failure lies within Tinder's application design and security implementation [67140, 72750, 67769]. The lack of proper encryption and data protection within the app itself allowed external actors to exploit these weaknesses, rather than external factors directly causing the failure. |
| Nature (Human/Non-human) | non-human_actions | (a) The software failure incident occurring due to non-human actions: - The software failure incident in the articles was primarily due to the lack of basic encryption protocols in Tinder's mobile apps. The vulnerabilities allowed for sensitive user data, such as profile photos and swiping actions, to be exposed to potential attackers on the same Wi-Fi network without human intervention [67140, 72750, 67769]. (b) The software failure incident occurring due to human actions: - The software failure incident was not directly caused by human actions but rather by the lack of proper security measures implemented by the developers of the Tinder app. The vulnerabilities were identified by researchers at Checkmarx, who highlighted the flaws in the app's security protocols and recommended necessary steps to mitigate the risks [67140, 72750, 67769]. |
| Dimension (Hardware/Software) | software | (a) The articles do not mention any software failure incident occurring due to contributing factors originating in hardware. Hence, there is no information available on a software failure incident related to hardware issues. (b) The software failure incident reported in the articles is due to contributing factors that originate in software. Specifically, the incident involves vulnerabilities in Tinder's mobile apps related to the lack of standard encryption necessary to keep user data secure [67140, 72750, 67769]. These vulnerabilities allowed attackers on the same Wi-Fi network to view profile photos, monitor swiping actions, and potentially even replace images without the user's knowledge. The flaws were related to the use of insecure HTTP connections instead of HTTPS, making it easier for hackers to intercept and manipulate data. Checkmarx, the security firm that discovered the vulnerabilities, recommended moving all operations to HTTPS and making encrypted packets less recognizable to enhance security. The incident highlights the importance of proper software security measures to protect user data and privacy. |
| Objective (Malicious/Non-malicious) | malicious | (a) The software failure incident related to Tinder's lack of encryption for photos and swipe data can be categorized as a malicious failure. Researchers at Checkmarx discovered vulnerabilities in Tinder's app that allowed attackers on the same Wi-Fi network to view users' profile photos, manipulate images, and track their swiping activity [67140, 72750, 67769]. These vulnerabilities could have been exploited for malicious purposes such as spying on users, altering images, or potentially engaging in blackmail schemes. The lack of encryption and security measures in Tinder's app exposed users to privacy risks and potential harm, indicating a malicious intent behind the failure incident. |
| Intent (Poor/Accidental Decisions) | poor_decisions | (a) poor_decisions: - The software failure incident related to Tinder's lack of encryption for photos and swipe data was due to poor decisions made by the company in terms of security measures [67140, 72750, 67769]. - The vulnerabilities in Tinder's app, such as using HTTP instead of HTTPS for profile pictures and having different file sizes for swipe actions, were highlighted as poor decisions that exposed user data to potential attacks [67140, 72750, 67769]. - Checkmarx, the app security firm, recommended that Tinder should have encrypted photos and made the encrypted packets less recognizable to prevent such vulnerabilities, indicating that the lack of these measures was a poor decision on Tinder's part [67140, 72750, 67769]. (b) accidental_decisions: - The software failure incident was not attributed to accidental decisions or unintended mistakes but rather to deliberate choices made by Tinder in terms of implementing security measures [67140, 72750, 67769]. - The vulnerabilities identified by Checkmarx were a result of conscious decisions made by Tinder, such as using insecure HTTP connections for profile pictures and not standardizing the file sizes for swipe actions, rather than being accidental in nature [67140, 72750, 67769]. |
| Capability (Incompetence/Accidental) | development_incompetence, accidental | (a) The software failure incident related to development incompetence is evident in the articles. Checkmarx, an application security company, discovered vulnerabilities in Tinder's mobile apps, specifically in the lack of basic HTTPS encryption for photos [67140, 72750, 67769]. The flaws allowed attackers on the same Wi-Fi network to view profile photos, swipe actions, and even inject their own images into users' photo streams. Despite Checkmarx disclosing these vulnerabilities to Tinder several months prior, the issues had not been fixed promptly, indicating a lack of professional competence in addressing security concerns. (b) The software failure incident related to accidental factors is also present in the articles. The vulnerabilities discovered by Checkmarx, such as the insecure HTTP connection for profile pictures and the distinguishable file sizes for swipe actions, were not intentional design choices but accidental oversights in Tinder's app security [67140, 72750, 67769]. These accidental flaws allowed potential attackers to exploit the app's security weaknesses, highlighting the unintended consequences of inadequate security measures. |
| Duration | temporary | (a) The software failure incident in the articles was temporary. The incident involved vulnerabilities in Tinder's security that allowed attackers on the same Wi-Fi network to view users' profile photos, swipes, and matches due to the lack of HTTPS encryption [67140, 72750, 67769]. These vulnerabilities were identified by researchers from Checkmarx and were later fixed by Tinder through security updates and encryption measures. The temporary nature of the incident is evident from the fact that the vulnerabilities were addressed and resolved by Tinder after being brought to their attention. |
