## プロジェクトの歴史と使われ方

chkrootkit is a long-running Unix rootkit detector that locally checks for signs of modified system binaries, log tampering, promiscuous interfaces, and kernel-module trojans.

### プロジェクトの歴史

The official README for version 0.59 credits Nelson Murilo as main author and Klaus Steding-Jessen as co-author. It describes chkrootkit as a shell-script front end plus C helpers including ifpromisc, chklastlog, chkwtmp, chkproc, chkdirs, check_wtmpx, chkutmp, and a strings replacement.

### 採用の歴史

The README lists testing across Linux, FreeBSD, OpenBSD, NetBSD, Solaris, HP-UX, Tru64, BSDI, and Mac OS X, which explains why it became common in Unix security packaging. The input package facts show it in Homebrew, Debian, Ubuntu, Fedora/DNF, and MacPorts.

### 使われ方

chkrootkit is intended to be run as root, either as ./chkrootkit for all tests or with named tests such as ps, ls, and sniffer. Options include quiet mode, expert mode, an alternate root directory, and an alternate command path for checking mounted disks or avoiding possibly compromised system binaries.

### パッケージ好きにとっての重要性

For package nerds, chkrootkit is a classic security-admin utility: small, scriptable, portable, and old enough to appear in many Unix package collections. It also shows why some security tools remain tarball-first rather than source-control-first in package metadata.

### タイムライン

- 2000s: README documents support for Linux 2.0 through 2.6, early BSD releases, Solaris, HP-UX, Tru64, BSDI, and Mac OS X.
- 2026: Official README identifies version 0.59.
- 2026: Homebrew packages chkrootkit 0.59 from the official chkrootkit.org FTP tarball.

### Related projects

- The README credits DFN-CERT tools chklastlog and chkwtmp and small portions of ifconfig by Fred N. van Kempen. It is often compared with other host compromise scanners, but its official documentation focuses on its bundled tests.
