TransUnionBreach8547/2025
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: TransUnion, a major credit bureau, experienced a data breach on **July 28** via a compromised third-party application. While hackers did not access core credit reports, they obtained **Social Security numbers and birth dates** of **69,000 Wisconsin residents** and **4 million people nationwide**. The exposed data—critical for identity theft—poses long-term risks, including unauthorized credit applications, loans, or fraud. Victims like Howard Pope, a Waupaca resident, reported receiving breach notifications and proactively froze their credit, but uncertainty remains about when or how attackers might exploit the stolen information. Wisconsin’s consumer protection agency confirmed TransUnion has not disclosed the perpetrators or their motives. The breach underscores vulnerabilities in systems handling sensitive personal data, with officials urging affected individuals to monitor credit reports weekly (via **annualcreditreport.com**) and utilize free credit monitoring offered by TransUnion. The incident highlights systemic risks when even credit bureaus—tasked with safeguarding financial identities—fail to prevent exposures.

Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: TransUnion, a major U.S. consumer credit reporting agency, suffered a data breach on **July 28, 2025**, exposing the personal information of **over 4.4 million Americans**. The incident stemmed from unauthorized access to a **third-party application** linked to its U.S. consumer support operations. While TransUnion stated the breach involved only **limited personal data**—excluding core credit reports or financial details—the exact nature of the compromised information remains undisclosed. The company is offering **24 months of free credit monitoring and identity theft protection** to affected individuals. The breach follows a pattern of recent attacks targeting **Salesforce-linked systems**, though TransUnion has not confirmed a direct connection. This marks another security lapse for the firm, which previously faced breaches in its **South African and Canadian branches** involving customer data exposure.

TransUnionBreach8549/2025
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: TransUnion, a major credit bureau, suffered a **data breach** exposing sensitive personal information of **4.4 million US consumers**. The compromised data includes **names, Social Security numbers (SSNs), and dates of birth**, though no credit information was accessed. The breach originated from unauthorized access to a **third-party application** supporting TransUnion’s US consumer operations. While the company claims the exposed data is limited, the leaked details (SSNs and DOBs) pose a **high risk of identity theft**. TransUnion is notifying affected individuals and offering support resources. Legal firms are already preparing class-action lawsuits. The incident highlights vulnerabilities in third-party vendor security, reinforcing the need for credit monitoring or freezes for impacted users.

TransUnionBreach8549/2025
Rankiteo Explanation :
Attack with significant impact with customers data leaks

The attack exposed **4.4–4.5 million customers’ sensitive personal information**, including **Social Security Numbers (SSNs)**, which heightens risks of **identity theft, financial fraud, and long-term misuse of personal data**. Unlike prior breaches involving less critical data, this incident involved highly sensitive identifiers, prompting TransUnion to offer **24 months of free credit monitoring and proactive fraud assistance** to affected individuals. The same group has allegedly targeted other high-profile entities like **Google, Allianz Life, Cisco, and Workday**, indicating a broader campaign. The breach underscores vulnerabilities in third-party hosted systems and the escalating sophistication of cybercriminal tactics targeting financial institutions.

While TransUnion claimed its **core credit database and credit reports remained uncompromised**, hackers allegedly stole **over 13 million records** in total, with ~4.4 million tied to U.S. individuals. The attack was attributed to the **extortion group ShinyHunters**, leveraging malicious third-party integrations or OAuth-connected apps disguised as legitimate Salesforce tools. TransUnion responded by offering **24 months of free credit monitoring and identity theft protection** to affected individuals and collaborating with law enforcement and cybersecurity experts for forensic analysis.

Description

WeGIA is an open source Web Manager for Institutions with a focus on Portuguese language users. Versions 3.5.4 and below contain a Stored Cross-Site Scripting (XSS) vulnerability in the /WeGIA/html/geral/configurar_senhas.php endpoint. The application does not sanitize user-controlled data before rendering it inside the employee selection dropdown. The application retrieves employee names from the database and injects them directly into HTML <option> elements without proper escaping. This issue is fixed in version 3.5.5.

Description

ZITADEL is an open-source identity infrastructure tool. Versions 4.0.0-rc.1 through 4.7.0 are vulnerable to DOM-Based XSS through the Zitadel V2 logout endpoint. The /logout endpoint insecurely routes to a value that is supplied in the post_logout_redirect GET parameter. As a result, unauthenticated remote attacker can execute malicious JS code on Zitadel users’ browsers. To carry out an attack, multiple user sessions need to be active in the same browser, however, account takeover is mitigated when using Multi-Factor Authentication (MFA) or Passwordless authentication. This issue is fixed in version 4.7.1.

Description

ZITADEL is an open-source identity infrastructure tool. Versions 4.7.0 and below are vulnerable to an unauthenticated, full-read SSRF vulnerability. The ZITADEL Login UI (V2) treats the x-zitadel-forward-host header as a trusted fallback for all deployments, including self-hosted instances. This allows an unauthenticated attacker to force the server to make HTTP requests to arbitrary domains, such as internal addresses, and read the responses, enabling data exfiltration and bypassing network-segmentation controls. This issue is fixed in version 4.7.1.
