          A whitelisting application has a list of what it knows it bad AND what it knows in advance to be good.

          How would it know this? Is this defined by a person/people? If so, that wouldn’t have mattered. liblzma was known in advance to be good, then the malicious update was added, and people still presumed that it was good.

          This wasn’t a case of some random package/program wreaking havoc. It was trusted malicious code.

          Also, you’re asking for an antivirus that uploads and uses a sandbox to analyze ALL packages. Good luck with that. (AVs would probably have a hard time detecting malicious build actions, anyways).

              It places unknown/new software in a sandbox. You want an AV that tests all pre-existing packages in a sandbox.

          That would do nothing for liblzma as it was trusted.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
