Virus Total.

Virus Total is a website created by the Spanish security company Hispasec Sistemas. Launched in June 2004, it was acquired by Google in September 2012. The company's ownership switched in January 2018 to Chronicle.

Virus Total aggregates many antivirus products and online scan engines to check for viruses that the user's own antivirus may have missed, or to verify against any false positives. Files up to 650 MB can be uploaded to the website, or sent via email (max. 32MB). Anti-virus software vendors can receive copies of files that were flagged by other scans but passed by their own engine, to help improve their software and, by extension, Virus Total own capability. Users can also scan suspect URLs and search through the Virus Total dataset. Virus Total for dynamic analysis of malware uses the Cuckoo sandbox. Virus Total was selected by PC World as one of the best 100 products of 2007.

•  Virus Total now protects developers from becoming false positives.

It’s been six years since Google acquired VirusTotal, a service that allows users to upload any file to check it for malware and viruses against the databases and algorithms of 70 antivirus and domain blacklisting services. Over the years, VirusTotal, which is now part of Alphabet’s Chronicle, has established itself as a neutral public service that has the trust of both users and developers, who can also access its service through an API.

Today, the company is expanding on its core services by launching a new tool that allows developers to scan new code against the systems of its antivirus partners to help ensure that those partners don’t mistakenly identify their code as malware. These kind of false positives are surprisingly common and can obviously create massive headaches for developers who aren’t in the malware business.

With VirusTotal Monitor, which is now available to all developers, developers can upload their code, have VirusTotal check it and if it’s mistakenly flagged as malware by one of the company’s partners, VirusTotal notifies both its partners and the developers– and connects them to make sure they can figure out a solution.

As VirusTotal tech lead Emiliano Martinez told me, it’s worth noting that false positives are not just a headache for developers but also a potential PR disaster for the antivirus industry. Those companies don’t want to be responsible when users suddenly can’t use the latest version of an application they depend on only because their antivirus tool mistakenly thought it was malware. “So what we came up with is something like a Google Drive to which software developers can upload what they create — and do so before launching a given piece of software — or after,” Martinez explained.

It’s worth noting that this tool is mostly geared toward commercial developers, but it’ll also be useful for developers who write line-of-business apps for larger companies, given that they often need that application to run their businesses.

VirusTotal Monitor is free for antivirus companies. The company plans to monetize the service by charging developers. “At the end of the day, whenever there is a false positive and you are blacked out, that is a huge revenue damage,” Martinez told me when I asked about the reason for this monetization model.

How it works.

VirusTotal inspects items with over 70 antivirus scanners and URL/domain blocklisting services, in addition to a myriad of tools to extract signals from the studied content. Any user can select a file from their computer using their browser and send it to VirusTotal. VirusTotal offers a number of file submission methods, including the primary public web interface, desktop uploaders, browser extensions and a programmatic API. The web interface has the highest scanning priority among the publicly available submission methods. Submissions may be scripted in any programming language using the HTTP-based public API.

As with files, URLs can be submitted via several different means including the VirusTotal webpage, browser extensions and the API.

Upon submitting a file or URL basic results are shared with the submitter, and also between the examining partners, who use results to improve their own systems. As a result, by submitting files, URLs, domains, etc. to VirusTotal you are contributing to raise the global IT security level.

This core analysis is also the basis for several other features, including the VirusTotal Community: a network that allows users to comment on files and URLs and share notes with each other. VirusTotal can be useful in detecting malicious content and also in identifying false positives -- normal and harmless items detected as malicious by one or more scanners.

• Free and unbiased.

VirusTotal is free to end-users for non-commercial use in accordance with our Terms of Service. Though we work with engines belonging to many different organizations, VirusTotal does not distribute or promote any of those third-party engines. We simply act as an aggregator of information. This allows us to offer an objective and unbiased service to our users.

• Many contributors.

VirusTotal's aggregated data is the output of many different antivirus engines, website scanners, file and URL analysis tools, and user contributions. The file and URL characterization tools we aggregate cover a wide range of purposes: heuristic engines, known-bad signatures, metadata extraction, identification of malicious signals, etc.

• Raising the global IT security level through sharing.

Scanning reports produced by VirusTotal are shared with the public VirusTotal community. Users can contribute comments and vote on whether particular content is harmful. In this way, users help to deepen the community’s collective understanding of potentially harmful content and identify false positives (i.e. harmless items detected as malicious by one or more scanners).

The contents of submitted files or pages may also be shared with premium VirusTotal customers. The file corpus created in VirusTotal provides cybersecurity professionals and security product developers valuable insights into the behaviors of emerging cyber threats and malware. Through our premium services commercial offering, VirusTotal provides qualified customers and anti-virus partners with tools to perform complex criteria-based searches to identify and access harmful files samples for further study. This helps organizations discover and analyze new threats and fashion new mitigations and defenses.

• Real-time updates.

Malware signatures are updated frequently by VirusTotal as they are distributed by antivirus companies, this ensures that our service uses the latest signature sets.

Website scanning is done in some cases by querying vendor databases that have been shared with VirusTotal and stored on our premises, and in other cases by API queries to an antivirus company's solution. As such, as soon as a given contributor blocklists a URL it is immediately reflected in user-facing verdicts.

• Detailed results.

VirusTotal not only tells you whether a given antivirus solution detected a submitted file as malicious, but also displays each engine's detection label (e.g., I-Worm.Allaple.gen). The same is true for URL scanners, most of which will discriminate between malware sites, phishing sites, suspicious sites, etc. Some engines will provide additional information, stating explicitly whether a given URL belongs to a particular botnet, which brand is targeted by a given phishing site, and so on.

Bad news for attackers: Virus Total can scan for malicious code in firmware.

What can you do if the reason for your computer infection is so deep that malicious code cannot be detected even with the best antivirus scans? Firmware has become a notoriously great place for mischief, with malware planted at the firmware level.

What is firmware? It is described as the low-level code that bridges the hardware and operating system at startup.

VirusTotal is a free online service that analyzes files and URLs. The service can help enable users to identify malicious content and now has added a tool for analyzing firmware. Since antivirus programs "are not scanning this layer, the compromise can fly under the radar," wrote Santos, a security engineer.
