Verizon Data Breach Investigations Report: What Are the Third-Party Risk Implications?

Prevalent’s Cyber & Business Monitoring Service includes built-in application security capabilities that perform sub-resource integrity checking—a security feature that enables browsers to verify that any resource they fetch (from a CDN, for example) and deliver has not been modified. That way, if a third-party script is compromised and malicious code is inserted, the browser will fail to load the script, since the cryptographic hash of the malicious script won’t match the known trusted hash in the integrity tag.

Use of stolen credentials is by far the number one hacking action variety

Remember above where we mentioned web applications as the top vector? Those exposed assets – combined with the number one hacking action – stolen credentials (figure 13 in the report) – pose a significant risk to organizations across all sectors. To combat this attack vector, Prevalent delivers reporting on phishing events in addition to dark web monitoring, providing some awareness of how often your vendors are being targeted and what malicious domains are being stood up as part of these campaigns. For example, we have seen situations where attackers have stood up a domain that masquerades as a login portal that customers of the vendor all share. Having this type of intelligence helps InfoSec teams blacklist the activity. See below for a screenshot of the phishing events report.

Speaking of credentials, it’s widely known that password reuse is a significant security lapse in nearly every organization. The problem is compounded when sysadmins reuse admin passwords across systems, or worse: use the same password for non-privileged and privileged accounts. Checking your vendor’s password management policies should be part of your vendor due diligence process – collected as part of a deep-controls-based assessment – helping to bring visibility to potentially bad password management practices which could be exploited to gain credentials for a breach.

Prevalent utilizes an industry-unique combination of technology, data analytics, and human analysts to deliver business risk assessments. Prevalent analysts collect, categorize, and score based on rules derived from a combination of methods including commercial due diligence, financial analysis, and cyber threat intelligence. With backgrounds in national security and cyber threat intelligence, Prevalent cyber analysts provide geopolitical context and fluency in seven languages.

Next steps

Insights from continuous monitoring can and should be used both internally and alongside results of internal controls-based assessments for a complete picture of your critical vendors that may have access to sensitive systems and data. In this blog we reviewed four such use cases: scanning for web application vulnerabilities and for stolen credentials on the dark web, assessing password policies, and monitoring for potential risks stemming from business events.
