Over 230,000 Comcast customers' personal data exposed in a massive ransomware attack on a third-party vendor. Learn more about the breach and its impact.

In early 2024, U.S. telecom giant Comcast confirmed that over 230,000 customers had their sensitive personal data stolen during a ransomware attack on Financial Business and Consumer Solutions (FBCS), a third-party debt collection agency based in Pennsylvania. This breach underscores the critical risks posed by outsourcing sensitive operations to external vendors and the pervasive threat of ransomware in the modern digital landscape.
The breach traces back to a cyberattack between February 14 and February 26, 2024, targeting FBCS’s systems. Initially, FBCS assured Comcast that no Comcast customer data had been compromised in the attack. However, in July 2024, FBCS revealed that the breach had, in fact, exposed data related to 237,703 Comcast customers. The stolen information includes:
These customers were primarily registered with Comcast around 2021, though Comcast had already stopped using FBCS for debt collection services by 2020.
The ransomware attack on FBCS involved unauthorized access to its computer network, during which time hackers downloaded sensitive data and encrypted several of FBCS’s systems. The perpetrators have not been identified, and no major ransomware group has claimed responsibility for the attack. FBCS’s own public statement only refers to the attacker as an “unauthorized actor.” The exact method of infiltration remains unknown, though typical vectors for ransomware attacks include phishing, malware, and exploiting known software vulnerabilities.
This breach is a textbook example of the vulnerabilities introduced when organizations rely on third-party vendors to handle sensitive data. In this case, although Comcast’s internal systems were not directly compromised, the company became collateral damage through its association with FBCS. The incident reveals a significant flaw in many organizations' cybersecurity strategies: while internal systems may be well-protected, outsourced services—often considered secondary—may be more vulnerable.
FBCS’s failure to promptly disclose the involvement of Comcast’s data in the breach further highlights the communication breakdown that often occurs in vendor relationships. Comcast learned in March 2024 that there had been a ransomware attack on FBCS but was not informed about the exposure of its customers' data until several months later. This delay in notification likely exacerbated the potential damage to Comcast’s customers.
The FBCS breach is part of a broader cyberattack that affected millions of individuals and several large organizations, demonstrating the wide-reaching impacts of such incidents. In total, FBCS reported that over 4 million people had their personal information compromised during the February 2024 ransomware attack.
CF Medical (Capio): A medical debt-purchasing company, CF Medical confirmed in September 2024 that more than 620,000 individuals had their health information, including medical claims, stolen in the breach. Health information is particularly sensitive, and the theft of such data heightens the risk of fraud and privacy violations.
Truist Bank: One of the largest banks in the U.S., Truist Bank confirmed that its customer data was also exposed during the attack, including names, addresses, account numbers, dates of birth, and Social Security numbers. Truist Bank, which has over 10 million customers, has yet to reveal how many of its customers were impacted, but the exposure of account and financial data raises concerns about potential identity theft and financial fraud.
The Comcast-FBCS breach has significant legal and regulatory consequences. Due to the type of data exposed—especially Social Security numbers and personal identification details—Comcast and FBCS are likely to face legal claims from affected customers. Both companies may also encounter regulatory scrutiny for their handling of the breach and the delayed notification of affected parties.
In the U.S., data breaches involving sensitive personal information often lead to class-action lawsuits, as seen in previous high-profile incidents. Comcast may be required to provide credit monitoring services and identity protection measures for affected individuals to mitigate the potential risks of identity theft. Additionally, as the incident involved multiple states, state attorneys general may investigate the breach, potentially leading to fines or sanctions for non-compliance with data protection laws, such as the California Consumer Privacy Act (CCPA) or the Maine Data Protection Act.
FBCS's role as the third-party vendor at the center of this breach cannot be overlooked. Despite their responsibility for protecting customer data, FBCS failed to secure critical information from its clients, including Comcast. Moreover, their delayed response and incomplete disclosure of the breach’s impact added to the potential damage for affected companies and individuals.
The situation calls for stricter regulatory oversight of third-party service providers, particularly those handling sensitive financial and medical data. Organizations like Comcast must ensure that their vendors adhere to robust cybersecurity frameworks and employ rigorous risk management practices.
Comcast’s decision to cease using FBCS for debt collection services in 2020 does not exempt it from responsibility for this breach. As the affected data dates back to 2021, Comcast will need to provide a clear explanation of how this older data was still in FBCS’s possession and what measures were in place to protect it.
In the wake of the breach, Comcast will likely implement additional measures to secure its data when working with third-party vendors. This includes:
Vendor Audits: Routine cybersecurity audits of all third-party vendors to ensure they comply with the company's data protection standards.
Data Encryption: Ensuring that all sensitive data—both at rest and in transit—is encrypted, even when stored by external service providers.
Stricter Contract Provisions: Future contracts with vendors may include stronger security requirements and financial penalties for breaches.
The Comcast-FBCS ransomware incident serves as a crucial reminder to industries relying on third-party services for sensitive operations. The breach highlights the importance of:
