Deciphering VirusTotal Results: A Comprehensive Approach to Threat Assessment

In the realm of cybersecurity, understanding the intricacies of VirusTotal results is crucial for accurate threat assessment. It’s a common misconception to think that a detection by only a handful of antivirus (AV) engines signifies a “probable false positive.” In reality, a nuanced approach is vital for effectively interpreting these findings.

The Importance of Context in Detection

Many users, myself included until recently, often fall into the trap of trivializing VirusTotal alerts. The first step in tackling these results is to recognize that detections can evolve over time. Therefore, if a file hasn’t been scanned recently, consider reanalyzing it. VirusTotal keeps track of previous scans and will display this historical data, which is invaluable for understanding potential risks.

It’s also essential to scrutinize the names of detected malware. For instance, a designation like “not-a-virus” can signify that while the file may be used in malicious contexts, it isn’t inherently harmful. However, be aware that not all antivirus providers label files the same way.

Investigating File Details

When assessing a file’s legitimacy, verify that its type aligns with what it claims to be. Additionally, consider the submission date. If the upload timestamp precedes the release of the software, it could indicate that the malware is recycled and should not be considered a threat.

Investigating alternate names associated with the file can provide further insights. If the file is listed under unrelated names, it’s likely a renamed malware variant. While generic names such as “update.exe” or seemingly random strings can typically be overlooked, they should still be approached with caution.

Analyzing Behavioral Patterns

Understanding how a file behaves is another fundamental part of your assessment. Examine what files it drops or deletes, and where these actions take place. For example, a software update should not attempt to disable crucial security features like Windows Defender, Command Prompt, or Task Manager.

Pay attention to highlighted behaviors in the report, such as specific API calls like GetTickCount. This particular function might be manipulated by malware to evade detection within virtual machines. For deeper insights into this behavior, refer to resources that analyze VM-aware malware.

Engaging with the Community

The VirusTotal community can be a double-edged sword; while it can provide helpful insights, it may also be cluttered with misinformation. Often, comments from users offer more value than the voting system, so it’s advisable
