      A few months ago, an anonymous user uploaded a PDF file to the online platform

       in order to see if it was detected by any of the more than 50 antivirus engines that have this platform or, otherwise, none of them detected it .This PDF file apparently seemed harmless and could have been a user who, after downloading it, wanted to verify that it did not hide anything. However, it seems that this PDF file hid something quite serious.

      This PDF file immediately called the attention of several security researchers subscribed to the platform, researchers who soon began to analyze it in depth.Within this PDF file they have been able to find two very dangerous exploits that took advantage of two security flaws still unknown in the Adobe software and in Windows.

      The Adobe vulnerability ( CVE-2018-4990 ) is a failure to execute remote code, while the Windows security failure ( CVE-2018-8120 ) is a privilege escalation failure to be able to execute code at the highest level of permits. The PDF file did not include the final payload and was not 100% complete, so it is believed that it has never been used.

      Neither this malicious PDF , nor the exploits that it hid, had never been seen on the network until they were sent to VirusTotal. It is not well known why this PDF came to this online security platform, whether it was from someone who got it in some way or by some rookie hackerwho does not know that all the files sent to VirusTotal are sent to security companies and researchers, even if apparently clean, for in-depth analysis.

      What is certain is that, thanks to VirusTotal, we have been able to avoid a series of very dangerous computer attacks, being able to know the vulnerability before it was used to endanger the security of the users.

      Update Windows and Adobe to protect yourself from these two vulnerabilities

      This PDF was detected in March of this same year, and in the second week of May Microsoft and Adobe released their corresponding security patches without giving specific details about these security flaws. However, in order to give system administrators enough time to update their infrastructures, it has not been until now that Microsoft and Adobe have made public the vulnerabilities that have been detected thanks to this PDF uploaded to VirusTotal .

      To protect ourselves from these two failures and make these exploits useless, we must install the latest Windows and Adobe security patches. These vulnerabilities were already solved the second week of May with the corresponding patches, so, installing these patches we will be fully protected.

      What do you think of these two security flaws discovered and solved thanks to VirusTotal?

      They buy or download a crypter and the first thing they do is upload it to VirusTotal, and then they tell you that they detect it as antivirus.
