Blue Cross Blue Shield of Montana (BCBSMT)
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: A third-party data breach involving **Conduent**, a business services provider for BCBSMT, exposed sensitive personal and medical data of up to **462,000 Montanans** between **November 8, 2024, and March 5, 2025**. Compromised information includes **names, addresses, birth dates, phone numbers, billing details, and medical records**. While BCBSMT’s internal systems remained unaffected, the breach was described as having **‘far-reaching and jaw-dropping consequences’** by Montana’s State Auditor, James Brown. The exposed data was exfiltrated by a **‘threat actor’** but, per Conduent, has not been publicly leaked or sold on the dark web. BCBSMT claimed to offer **credit monitoring** to affected customers, though regulators reported delays in notifications. The incident prompted a **full-scale state investigation**, new cybersecurity initiatives, and a public awareness campaign to mitigate identity theft risks. Authorities emphasized **accountability, transparency, and legal action** against responsible parties.

The exposed data included **names, addresses, dates of birth, telephone/fax numbers, email addresses, medical record numbers, health plan beneficiary numbers, account numbers, billing information, and service dates**.

Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: A massive data breach at **Blue Cross-Blue Shield of Montana**, the state’s largest health insurer, exposed the sensitive personal and healthcare data of **462,000 customers**—nearly one-third of Montana’s population. The breach, caused by a **third-party vendor (Conduent)**, lasted from **October 2024 to January 2025** but was only disclosed in **October 2025**, nearly a year after discovery. Compromised data included **birth dates, Social Security numbers, and health condition records**, highly targeted by cybercriminals for identity theft, fraud, and dark web sales. Victims face risks of **medical identity theft (average cost: $20,000 per incident)**, lost healthcare coverage, increased premiums, and long-term financial harm. The company failed to encrypt data, delete obsolete records, or notify affected individuals promptly, violating Montana’s breach disclosure laws. A **class-action lawsuit** alleges negligence, breach of contract, and violations of consumer protection laws, seeking damages, security reforms, and a decade of third-party monitoring. The breach has already led to **spam, fraud calls, and identity theft cases**, with victims unable to mitigate risks due to delayed alerts.

Breach
Rankiteo Explanation
Attack threatening the organization’s existence
Description: Blue Cross Blue Shield of Montana (BCBSMT) suffered a large-scale data breach via a third-party vendor, **Conduent**, between late 2024 and early 2025. The incident compromised the **personal and medical information** of **462,000 Montanans**—nearly **one-third of the state’s population**. Exposed data included **names, addresses, birth dates, billing and medical records, phone numbers, and other sensitive details**. The breach triggered an investigation by Montana’s **State Auditor and Insurance Commissioner**, James Brown, who criticized BCBSMT for delays in notification and transparency. The fallout led to regulatory scrutiny, potential enforcement actions, and a public awareness campaign urging affected residents to monitor financial and insurance statements for fraud. BCBSMT’s response remains under legal constraint, with the company declining to comment on pending litigation. The breach’s scale and sensitivity of leaked data—spanning **health and financial records**—pose severe risks of **identity theft, medical fraud, and long-term reputational damage** to both BCBSMT and the impacted individuals. Montana’s government deployed an **AI assistant** to manage the surge in consumer inquiries, highlighting the breach’s systemic impact on state-level cybersecurity and regulatory frameworks.

Description
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.

Description
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.

Description
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Integer Overflow vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions. This issue has been patched in version 1.3.2.

Description
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, working with large buffers in Lua scripts can lead to a stack overflow. Users of Lua rules and output scripts may be affected when working with large buffers. This includes a rule passing a large buffer to a Lua script. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling Lua rules and output scripts, or making sure limits, such as stream.depth.reassembly and HTTP response body limits (response-body-limit), are set to less than half the stack size.

Description
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.
