Supply Chain Compromise: Compromise Software Supply Chain

From MITRE ATT&CK 19.2

Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise. Supply chain compromise of software can take place in a number of ways, including manipulation of the application source code, manipulation of the update/distribution mechanism for that software, or replacing compiled releases with a modified version.

Targeting may be specific to a desired victim set or may be distributed to a broad set of consumers but only move on to additional tactics on specific victims.

How MITRE says to detect it DET0309

Compromised software/update chain (installer/write → first-run/child → egress/signature anomaly)

Windows Analytic 0862

Adversary ships a tampered application or update: an updater/installer (msiexec/setup/update.exe/vendor service) writes or replaces binaries; on first run it spawns scripts/shells or unsigned DLLs and beacons to non-approved update CDNs/hosts. Detection correlates: (1) process creation of installer/updater → (2) file metadata changes in program paths → (3) first-run children and module/signature anomalies → (4) outbound connections to unexpected hosts within a short window.

  • WinEventLog:Sysmon EventCode=13, 14
  • WinEventLog:Sysmon EventCode=3, 22
  • WinEventLog:Microsoft-Windows-CodeIntegrity/Operational Unsigned or invalid image for newly installed/updated binaries
  • NSM:Flow First-time egress to non-approved update hosts right after install/update

Linux Analytic 0863

A compromised package/update (deb/rpm/tarball/AppImage/vendor updater) is installed, writing/overwriting files in /usr/local/bin, /usr/bin, /opt, or ~/.local; first run executes unexpected shells/curl/wget and connects to unapproved hosts. Correlate package/updater execution → file writes/replace → first-run child processes → egress.

  • auditd:SYSCALL execve
  • journald:package dpkg/apt/yum/dnf transaction logs; vendor updaters in systemd journals
  • NSM:Flow New outbound flows to non-approved vendor hosts post install

macOS Analytic 0864

A tampered app/pkg/notarized update is installed via installer, softwareupdated, Homebrew, or vendor updater; new Mach-O or bundle contents appear in /Applications, /Library, /usr/local or /opt/homebrew; first run spawns sh/zsh/osascript/curl and makes egress to unfamiliar domains; AMFI/Gatekeeper may log signature/notarization problems.

  • macos:unifiedlog pkginstalld/softwareupdated/Homebrew install transactions
  • macos:endpointsecurity exec
  • NSM:Flow New/rare egress to non-approved update hosts after install
