Rootkit Packaged for Debian

Erich writes "Debian Developer Simon Richter announced in this posting to debian-devel that he Intends to Package (ITP) a R00tk1t for Debian Linux. The rootkit will make use of debian mechanisms such as diversions to divert the original /bin/ls commands and replace them cleanly by the modified versions. Even reinstalling or upgrading the file-utils package (containing /bin/ls) will then not remove the modified /bin/ls and the rootkit will stay active, being probably the first upgrade-resistant rootkit! This rootkit will then be easy to install by doing "apt-get install rootkit" - a major useability aspect for our fellow wannabe-hackers, making Debian the premier choice for them."

    While I'm sure the ITP announcement is a joke, it's a real issue that we shouldn't dismiss casually.

    How do we determine whether a system has been compromised? One good way is to check the package information - one of my backburner projects is a configuration management tool that reads the installed package list, rips apart published .deb files to determine the equivalence of tripwire data, and then compares what the .deb file says the files should look like against what's actually on the system.

    (In practice, I only rip the data once and create a Berkeley DB file mapping full path to a snapshot of the expected "struct stat" and the crypto hashes. Subsequent checks just walk the FS tree.)

    It even cross-references what's on the disk under /usr, /bin, /sbin, /lib and /etc (excluding /usr/local and /usr/src), and lists both unexpected and missing files in addition to modified files.

    But if somebody has installed a package using registered diversions to redirect standard programs, my CM tool won't issue any warnings. Why should it? The local administrator has to have the final word, and an unexplained symlink is flagged. But a registered diversion (since I also check some of the system Debian databases) isn't.

    Still sleeping at night? Remember all it takes is _one_ trojaned package, e.g., something downloaded from SourceForge or Freshmeat, with an installation script that illicitly adds a black hat key to the keyring for packagers. You can't require all updates be signed by a master key without killing off all local and independent packagers.

    (It is left as an exercise for the reader why you can't just have Debian maintain a master key used to sign independent developer keys. They can and should sign their own, but not Joe Smith who just wants to modify lprng so he doesn't have to reconfigure each system by hand.)
