![]() ![]() When malware authors upload their work to VirusTotal, it acts as a double-edged sword. The authors can easily determine if their code has been discovered or blocked by most major security vendors, but they also run the risk and increase the chances of being discovered. Files and URLs submitted to VirusTotal are permanently stored and become available to anyone who wishes to examine or analyze them. What exactly is VirusTotal? VirusTotal is an online security platform used by developers and security researchers to upload code, URLs, or files they wish to be analyzed. The data is uploaded to VirusTotal for analysis and run through over 70 different anti-virus engines and blacklisting services from most of the major security vendors. It is a completely free service and legitimate users would normally upload a file to check if it is malicious or to find out if code they are writing would be incorrectly flagged (false positive) as malicious by any AV engines or blacklisting services. The results of the analysis are freely shared publicly and with the participating security vendors in order to improve their catch rate (win-win-win).
