What is vendor compromise?

Vendor compromise is a cybersecurity threat, particularly in healthcare, where organizations reliant on third-party vendors for services are at an increased risk of an attack. An alarming statistic from SecurityScorecard revealed that 98% of organizations have at least one third-party vendor that has suffered a data breach. These breaches can directly impact a healthcare organization's ability to operate and serve patients.  

What is vendor compromise? 

A vendor compromise occurs when unauthorized parties access a company's data through one of its vendors. Vendors are companies that provide services or products to other businesses. According to a study from the National Technical University of Ukraine, “This form of targeted social engineering attack exploits trust for suppliers as its basic concept.” If a vendor has weak security, hackers can exploit the vulnerability to access sensitive data. 

Threat actors specifically target healthcare organizations through vendor compromise because of the valuable data these institutions hold. Patient records are rich with sensitive details, such as Social Security numbers, medical histories, and insurance information, making them prime targets for identity theft and fraud.

The impact of an attack

Vendor compromise attacks often start with cybercriminals identifying vulnerabilities in a vendor's security systems. They might send phishing emails that look legitimate to trick employees into revealing their login credentials. Alternatively, attackers may exploit outdated software or unpatched security flaws to install malware that gives them unauthorized access.

After a breach, teams should begin a focused investigation to pinpoint how the breach occurred and the scope of the data exposed. As organizations uncover details, they should notify affected patients and regulatory bodies as needed. The process isn't just a legal formality—it often requires pulling in extra staff or cybersecurity experts, which can increase operational costs. 

To prevent further damage, urgent upgrades to IT systems may be necessary, sometimes forcing temporary shutdowns of vulnerable services. Each step has the potential to lead to delays in patient care and services.

The role of vendor management in healthcare cybersecurity

A central idea around vendor management (or VM), is that the number of vendors required should be reduced. According to a study from the Indian Journal of Economics and Business, it is better “To hire a single experienced and capable partner who can manage a variety of services single handedly and thereby reduce the potential risk involved with the operation of outsourcing.”

Vendor management is a strategy in healthcare that focuses on overseeing relationships with suppliers and service providers. It starts with carefully selecting vendors who align with a company's needs, followed by establishing clear collaboration terms. Through constant monitoring, healthcare organizations ensure that vendors meet both deadlines and quality standards.

A proactive vendor management strategy is instrumental in preventing vendor compromises. Through the rigorous assessment of security measures and compliance before partnering with vendors, a strong foundation of trust and security is built.
