I installed Fedora 19, and immediately listed the /usr/bin directory and saved the listing to a file. 4 hours later I list it again and all the executables have grown in size by about 1668 bytes. 'mkdir' for instance was originally 53504 bytes, now it has become 55172 bytes. I confirmed this by going into the Fedora installation dvd, then directory Packages/c/coreutils.... and using Engrampa to extract mkdir. It should be 53504 bytes long.On inspection, comparing the two files, it seems like an selinux section has been hacked out and tacked on to the end. Did a virus writer do this just to show that selinux is no match?? Have I been hit with a virus?
Is the reader's linux '/usr/bin/mkdir' file larger than 53504 bytes? Has the reader got a virus?
