In the ever-evolving landscape of cybersecurity, businesses are continually seeking ways to protect their sensitive data and proprietary code from malicious threats. While services like VirusTotal offer a valuable resource for analyzing files and URLs against multiple antivirus engines, there are significant concerns and risks associated with using such platforms, particularly for corporate users handling sensitive information and proprietary code. This can be seen in their website home page and further elaborated in this page:

1. Privacy and Data Confidentiality:

One of the primary concerns for corporate users is the potential compromise of privacy and data confidentiality. When sensitive files are submitted to VirusTotal, they become part of the shared corpus accessible to premium customers and antivirus partners. This poses a risk of exposure to proprietary information, trade secrets, or other sensitive details that could be exploited by malicious actors.

Example: Consider a software development company submitting proprietary code to VirusTotal for analysis. If this code is accessible to premium customers, competitors, or unauthorized entities, it could lead to intellectual property theft or compromise the integrity of the company’s software.

2. Lack of Control Over Shared Information:

Corporate users may find it challenging to maintain control over the information shared on VirusTotal. The service shares scanning reports with the public community, allowing users to comment and vote on the harmfulness of content. This open collaboration may expose sensitive details to a wider audience, potentially leading to unintended consequences.

Example: Imagine a company submitting a URL containing a confidential internal tool to VirusTotal. If the community identifies it as harmful, even if its a false positive, it could impact the companys reputation and create unnecessary scrutiny.

3. Risk of False Positives and Misclassification:

VirusTotal aggregates data from various antivirus engines and false positives can occur. When dealing with proprietary code or sensitive files, misclassifications as malicious content can have severe consequences, impacting business operations and causing unnecessary panic.

Real-world Example:
A company’s proprietary encryption algorithm might trigger false positives due to its complexity. If misclassified as malicious, it could lead to unwarranted investigations and damage the company’s credibility.

4. Limited Analysis Control and Customization:

VirusTotal provides a standardized analysis based on its set of tools and engines, offering limited control over the analysis process. For corporate users with unique security requirements and proprietary algorithms, the lack of customization options may be a significant drawback.

Example: Consider a company with specialized security measures in its code that are not recognized by common antivirus engines. VirusTotal may flag these measures as suspicious, leading to a lack of understanding and potentially harmful misinterpretations.

5. Potential Legal and Compliance Issues:

Submitting sensitive or proprietary information to a third-party service like VirusTotal may raise legal and compliance concerns. Depending on the nature of the data and applicable regulations, companies may inadvertently violate privacy laws or breach contractual agreements by using external services for file analysis.

Example: In industries governed by strict data protection regulations, such as healthcare or finance, submitting patient records or financial data to VirusTotal could lead to severe legal consequences and regulatory penalties. While VirusTotal is a valuable tool for general file and URL analysis, corporate users with sensitive

details and proprietary code should exercise caution. The risks associated with privacy, lack of control, false positives, limited customization, and potential legal issues highlight the need for alternative solutions that prioritize data protection and meet the specific security requirements of businesses.

As an alternative, companies handling proprietary code may benefit from specialized source code review services, such as those offered by The Red Team Labs. These services provide comprehensive analysis and evaluation of source code, ensuring a thorough understanding of security risks and vulnerabilities without compromising the confidentiality of sensitive information.
