What is VirusTotal
VirusTotal is a free online service that allows users to analyze files and URLs for the presence of malware, viruses, worms, trojans, and other malicious content. It uses multiple antivirus engines and website scanners to perform the analysis, providing a comprehensive report on the potential security threats associated with a specific file or website.
VirusTotal was created in 2004 by Spanish company Hispasec Sistemas and was later acquired by Google in 2012. The service is widely used by security professionals, researchers, and everyday users to identify and avoid security risks. Users can upload a file or submit a URL to VirusTotal’s website, where it will be scanned and analyzed by multiple antivirus engines. The resulting report will provide details on the findings and an overall verdict on whether the file or URL is safe or malicious.

How to useVirusTotal?
Access the VirusTotal website: Open your web browser and navigate to the VirusTotal website at https://www.virustotal.com/.
Choose your method of scanning:a. File scanning: To scan a file, click on the “Choose file” button or the “File” tab on the homepage. This will open a file explorer window. Locate and select the file you want to analyze, then click “Open” to upload the file to VirusTotal. The maximum file size allowed is 650 MB.b. URL scanning: To scan a URL, click on the “URL” tab on the homepage. Enter the URL you want to analyze in the input field, and then click the “Scan it!” button.
Wait for the analysis: VirusTotal will now analyze the uploaded file or URL using multiple antivirus engines and website scanners. Depending on the size of the file or the number of engines being used, this process might take a few seconds to several minutes.
Review the results: Once the analysis is complete, you’ll see a detailed report with the results from each antivirus engine and scanning tool. The report will show whether the file or URL has been flagged as malicious by any of the participating engines. If a significant number of engines detect a threat, it’s likely that the file or URL is indeed malicious.
Make informed decisions: Based on the results, you can decide whether to proceed with caution, avoid the file or URL, or seek additional information from other sources.

Remember that VirusTotal should be used as a supplementary security measure and not as a replacement for dedicated antivirus software.
Exploring VirisTotal and Its Features:
As a demo, let’s scan a malicious IOC belonging to the Batloader trojan and analyzing the results. We can look up hashes in any commonly used hashing algorithms like MD5, SHA256, etc.
Hash used- 61e0926120f49b3d5edf3a5e0842b04640911974ecbbc93b6b33ca20c1f981bc
Exploring the Dashboard
When we do a lookup for the above-provided hash, we will see the above results. We will investigate the details of what all parameters are:
We can see a detection rate that shows a 34/60 score which means out of the 60 anti-malware tools, 34 engines have tagged that file as malicious.
This explains that 34 security vendors have tagged that file as malicious.
The third box represents the last time the file was scanned in the above case. The last scan happened a month ago.
This shows that the hash value belongs to a JavaScript file.
These symbols show that.
We can automate this information using API.
We can request a new scan.
Graphical representation of the malicious activity done by that file.
The VirusTotal flagged the hash as Batloader malware.
Exploring Detection Tab
This tab shows which security vendors tagged the file as malicious or clean. In this case, we can see that the file was labeled as a ‘trojan.batloader’ clearly. This tab shows details of which all security vendors have flagged this file as malicious. In the below image, we can see some of the famous security vendors, like Avast, BitDefender, etc., also flagged this file as malicious.
Exploring Details Tab
This tab will provide us with the full details on the file related to the hash. Whatever hash format we are uploading, we can see other hash algorithms, the file type, when the file was first submitted inVirusTotal, the last submission, the last analysis, what all names the file is known as, etc.
Exploring Relations Tab
This tab will show you to which all domains or IPs that file has communicated. This tab also has a very advanced feature of representing the whole attack in a graphical format showcasing every minute detail required.
As you can see, the graph shows us the domains and IPs to which the malicious file has communicated, and it also shows which region these IPs belong to and also provides graphs on the presence of the file reported.
Exploring Behavior Tab
This tab gives more details on the behavior analysis of the malware. Here we can see all MITRE signatures related to the file, IDS rules, and Sigma rules, if any. So, all these details will help in hunting malware within an organization.
Exploring Community tab
This is the tab where we can see all the community contributions. Researchers who observe any further details can give more input and give back to the community.
Domain or IP analysis using VirusTotal
We can search the reputation of any IP or domain inVirusTotal. The process is the same, but let’s see what extra details we can observe while analyzing an IP or domain. I uploaded a malicious IP and domain, and apart from the analysis which we discussed above, we can see ‘who is’ information on the domain. This contains the creation date of the domain, expiry date, registrar details, name server details, etc.
How Can You Contribute to The Society?
We saw all the information available while we looked for an artifact. Now in some cases, the score might be 0, i.e., it is not malicious; however, we cannot conclude that the file is clean. The reason might be that the security vendors haven’t flagged it as malicious yet. In such cases, if we as a researcher are sure that the file is malicious or clean, we can give a vote in the community score. We can also add comments in the community tab section.
