Is it though? The attacker probably has Linux x86 target(s) in mind and IFUNC support isn't guaranteed to work with other platforms.

  Checking for Linux makes sense. Doing the exact same check for Linux five times in a row is mysterious.

    It would be an interesting plot twist if the whole thing was an AI hallucination.

      ...or a stalking horse by somebody in Microsoft's marketing division.

      How about an AI trying to make itself some spare CPU cycles available ?

    Perhaps expected a very fast machine that might blast straight through the first few checks. Like how you needed two STOP statements in a Cray Fortran program in case it blew through the first one at 80MIPS.

  why doesn't IFUNC work on Linux ARM64?
  • bodyfour 3y ago
    IFUNC is supported on several architectures, including ARM64. The malicious code that the xz backdoor inserts into the library is a compiled x86_64 object file so it only is targeting one platform.
    • ycombinatrix 3y ago
      yea i know the backdoor is AMD64 only. the parent comment said IFUNC isn't supported on ARM64 which is incorrect.
