Description: The California Office of the Attorney General reported a data breach involving Anthem Blue Cross on November 20, 2013. The breach occurred due to a PDF document posted on the Anthem website from October 23, 2013, until October 24, 2013, which erroneously displayed provider Tax Identification Numbers. The affected information included names, business addresses, and potentially Social Security Numbers, although it was stated that there was no reason to believe the Social Security Numbers had been compromised.
Description: The second-biggest health insurer in the country, Anthem, recently experienced a data breach that was examined by experts at the security company Check Point. The first indications of the attack, according to statements made public by Anthem, appeared in the middle of last week when an IT administrator discovered a database query was being executed using his identifying code even though he had not started it. After concluding that an attack had taken place, the corporation notified the FBI and engaged a third-party security consultant to conduct an investigation. Investigators have revealed that Anthem's networks were breached and data was stolen using specially designed malware. Although the precise malware type is unknown, it is said to be a variation of a well-known family of hacking tools.
Description: The California Office of the Attorney General reported that Anthem Blue Cross experienced a data breach on May 7, 2022, affecting personal and protected health information (PHI) of individuals. The breach, which involved unauthorized access to data from a vendor, was reported on September 28, 2022.
Description: The California Office of the Attorney General disclosed a data breach at **Anthem Blue Cross**, where unauthorized access to its member portal occurred between **October 1, 2021, and October 14, 2021**. The incident exposed sensitive personal information of affected individuals, including **names, dates of birth, addresses, email addresses, phone numbers, and healthcare identification numbers**. While the breach did not involve financial data or medical records, the exposure of personally identifiable information (PII) poses risks such as identity theft, phishing attacks, and fraudulent activities targeting the victims. The breach was officially reported on **November 24, 2021**, highlighting a delay in detection and disclosure. As a healthcare provider, Anthem Blue Cross handles vast amounts of sensitive customer data, making this incident particularly concerning due to the potential for long-term reputational damage and regulatory scrutiny under laws like **HIPAA (Health Insurance Portability and Accountability Act)**. The lack of evidence suggesting ransomware or a broader systemic attack narrows the scope to unauthorized data access, but the scale of exposed records underscores the severity of the incident.
Description: On November 19, 2025, Anthem, Inc., a major health insurance provider, disclosed a severe data breach exposing **personally identifiable information (PII)** and **protected health information (PHI)** of at least **1,162 individuals in Massachusetts**. The compromised data includes **names, addresses, dates of birth, Social Security numbers, medical records, and driver’s license numbers**—high-value targets for identity theft, financial fraud, and blackmail.The breach’s gravity stems from the **sensitivity and volume of exposed data**, combining PII (e.g., SSNs, driver’s licenses) with PHI (medical records), significantly elevating risks for affected individuals. Such data can fuel **medical identity theft, insurance fraud, or extortion**, while the inclusion of government-issued identifiers (SSNs) enables long-term identity exploitation.Anthem’s response remains under investigation, but typical protocols involve **regulatory notifications, victim outreach (e.g., letters), and credit monitoring offers**. The incident underscores critical vulnerabilities in healthcare data security, where breaches of this nature often trigger **legal repercussions, reputational damage, and erosion of customer trust**. The ongoing probe may reveal further scope, but the confirmed exposure already poses **substantial financial, operational, and personal harm risks** to victims and the organization.
Description: The biggest health insurance provider in the US, Anthem, has agreed to pay $115 million to resolve a class-action lawsuit resulting from the 2015 data breach. Experts who looked into the matter concluded that the attack on Anthem, which revealed 78.8 million records, was most likely a slow, covert information theft that took place over several months rather than a typical smash-and-grab operation. Using a bot infection to steal data from the corporation, the attack was carried out in order to evade detection by the IT and security staff. Names, birth dates, residences, and medical ID numbers are included in the data; financial and health information was kept private.

Zerobyte is a backup automation tool Zerobyte versions prior to 0.18.5 and 0.19.0 contain an authentication bypass vulnerability where authentication middleware is not properly applied to API endpoints. This results in certain API endpoints being accessible without valid session credentials. This is dangerous for those who have exposed Zerobyte to be used outside of their internal network. A fix has been applied in both version 0.19.0 and 0.18.5. If immediate upgrade is not possible, restrict network access to the Zerobyte instance to trusted networks only using firewall rules or network segmentation. This is only a temporary mitigation; upgrading is strongly recommended.
Open Source Point of Sale (opensourcepos) is a web based point of sale application written in PHP using CodeIgniter framework. Starting in version 3.4.0 and prior to version 3.4.2, a Cross-Site Request Forgery (CSRF) vulnerability exists in the application's filter configuration. The CSRF protection mechanism was **explicitly disabled**, allowing the application to process state-changing requests (POST) without verifying a valid CSRF token. An unauthenticated remote attacker can exploit this by hosting a malicious web page. If a logged-in administrator visits this page, their browser is forced to send unauthorized requests to the application. A successful exploit allows the attacker to silently create a new Administrator account with full privileges, leading to a complete takeover of the system and loss of confidentiality, integrity, and availability. The vulnerability has been patched in version 3.4.2. The fix re-enables the CSRF filter in `app/Config/Filters.php` and resolves associated AJAX race conditions by adjusting token regeneration settings. As a workaround, administrators can manually re-enable the CSRF filter in `app/Config/Filters.php` by uncommenting the protection line. However, this is not recommended without applying the full patch, as it may cause functionality breakage in the Sales module due to token synchronization issues.
Zed, a code editor, has an aribtrary code execution vulnerability in versions prior to 0.218.2-pre. The Zed IDE loads Model Context Protocol (MCP) configurations from the `settings.json` file located within a project’s `.zed` subdirectory. A malicious MCP configuration can contain arbitrary shell commands that run on the host system with the privileges of the user running the IDE. This can be triggered automatically without any user interaction besides opening the project in the IDE. Version 0.218.2-pre fixes the issue by implementing worktree trust mechanism. As a workaround, users should carefully review the contents of project settings files (`./zed/settings.json`) before opening new projects in Zed.
Zed, a code editor, has an aribtrary code execution vulnerability in versions prior to 0.218.2-pre. The Zed IDE loads Language Server Protocol (LSP) configurations from the `settings.json` file located within a project’s `.zed` subdirectory. A malicious LSP configuration can contain arbitrary shell commands that run on the host system with the privileges of the user running the IDE. This can be triggered when a user opens project file for which there is an LSP entry. A concerted effort by an attacker to seed a project settings file (`./zed/settings.json`) with malicious language server configurations could result in arbitrary code execution with the user's privileges if the user opens the project in Zed without reviewing the contents. Version 0.218.2-pre fixes the issue by implementing worktree trust mechanism. As a workaround, users should carefully review the contents of project settings files (`./zed/settings.json`) before opening new projects in Zed.
Storybook is a frontend workshop for building user interface components and pages in isolation. A vulnerability present starting in versions 7.0.0 and prior to versions 7.6.21, 8.6.15, 9.1.17, and 10.1.10 relates to Storybook’s handling of environment variables defined in a `.env` file, which could, in specific circumstances, lead to those variables being unexpectedly bundled into the artifacts created by the `storybook build` command. When a built Storybook is published to the web, the bundle’s source is viewable, thus potentially exposing those variables to anyone with access. For a project to potentially be vulnerable to this issue, it must build the Storybook (i.e. run `storybook build` directly or indirectly) in a directory that contains a `.env` file (including variants like `.env.local`) and publish the built Storybook to the web. Storybooks built without a `.env` file at build time are not affected, including common CI-based builds where secrets are provided via platform environment variables rather than `.env` files. Storybook runtime environments (i.e. `storybook dev`) are not affected. Deployed applications that share a repo with your Storybook are not affected. Users should upgrade their Storybook—on both their local machines and CI environment—to version .6.21, 8.6.15, 9.1.17, or 10.1.10 as soon as possible. Maintainers additionally recommend that users audit for any sensitive secrets provided via `.env` files and rotate those keys. Some projects may have been relying on the undocumented behavior at the heart of this issue and will need to change how they reference environment variables after this update. If a project can no longer read necessary environmental variable values, either prefix the variables with `STORYBOOK_` or use the `env` property in Storybook’s configuration to manually specify values. In either case, do not include sensitive secrets as they will be included in the built bundle.
