28 Windows macOS and Linux antivirus with major security flaws, RACK911 Labs, This is how antivirus protection ceases to be effective,We already have clear which are the best antivirus for different operating systems based on different studies of security firms. However, no one is spared from security holes, neither operating systems nor applications.

In this case, major security flaws have been discovered in a total of 28 antiviruses. This list highlights some of the most downloaded for Windows, macOS and Linux. We give you all the details and the list of those affected after the jump.

Antiviruses are a type of software that protects us from the different threats that circulate in cyberspace. The problem comes when that protection can be deactivated without us realizing it.

This would make it unable to detect malware and neutralize it before it affects us. It would also have to be seen what would happen if the operating system was allowed to perform certain actions that could compromise that protection. That is precisely what they have discovered since RACK911 Labs using directory junctions (Windows) and symlinks (macOS and Linux).

This is how antivirus protection ceases to be effective

Most antivirus work in a similar way. When an unknown file is attempted to be copied to the computer, it performs a scanning it. If suspicious, it moves you to a safe location (quarantine). There the user instructions are awaited, although it can also be removed directly depending on the configuration.

Antiviruses usually work with administrator permissions, allowing them to have the highest level of “authority” in the operating system. That turns against us when there is a security breach. The aforementioned security firm has demonstrated a method to bypass antivirus security by taking advantage of all this.

The security problem would be present in Windows, macOS and Linux, these being the affected antivirus:

Windows

  • Avast Free Anti-Virus
  • Avira Free Anti-Virus
  • BitDefender GravityZone
  • Comodo Endpoint Security
  • F-Secure Computer Protection
  • FireEye Endpoint Security
  • Intercept X (Sophos)
  • Kaspersky Endpoint Security
  • Malwarebytes for Windows
  • McAfee Endpoint Security

Linux

  • BitDefender GravityZone
  • Comodo Endpoint Security
  • Eset File Server Security
  • F-Secure Linux Security
  • Kaspersy Endpoint Security
  • McAfee Endpoint Security
  • Sophos Anti-Virus for Linux

The security firm gave antivirus manufacturers up to 6 months to fix the security flaws. They consider that it is sufficient time before making it public. Most have set to work to close security flaws, but there are some exceptions that must be consulted individually.

RACK911 Labs has decided to publish it now so that everyone ends up closing the security holes now that the problem is in the public domain. At the user level, we only have to have the antivirus updated to the latest version.
