Supply Chain Compromise

From MITRE ATT&CK 19.2

Adversaries may manipulate products or product delivery mechanisms prior to receipt by a final consumer for the purpose of data or system compromise.

Supply chain compromise can take place at any stage of the supply chain including:

  • Manipulation of development tools
  • Manipulation of a development environment
  • Manipulation of source code repositories (public or private)
  • Manipulation of source code in open-source dependencies
  • Manipulation of software update/distribution mechanisms
  • Compromised/infected system images (removable media infected at the factory)
  • Replacement of legitimate software with modified versions
  • Sales of modified/counterfeit products to legitimate distributors
  • Shipment interdiction

While supply chain compromise can impact any component of hardware or software, adversaries looking to gain execution have often focused on malicious additions to legitimate software in software distribution or update channels. Adversaries may limit targeting to a desired victim set or distribute malicious software to a broad set of consumers but only follow up with specific victims. Popular open-source projects that are used as dependencies in many applications may also be targeted as a means to add malicious code to users of the dependency.

In some cases, adversaries may conduct “second-order” supply chain compromises by leveraging the access gained from an initial supply chain compromise to further compromise a software component. This may allow the threat actor to spread to even more victims.

How MITRE says to detect it DET0537

Behavioral detection for Supply Chain Compromise (package/update tamper → install → first-run)

Windows Analytic 1480

1) New or updated software is delivered/installed from atypical sources or with signature/hash mismatches; 2) installer/updater writes binaries to unexpected paths or replaces existing signed files; 3) first run causes unsigned/abnormally signed modules to load or child processes to execute, optionally followed by network egress to new destinations.

  • WinEventLog:Sysmon EventCode=1
  • WinEventLog:Sysmon EventCode=7
  • WinEventLog:Sysmon EventCode=11
  • WinEventLog:Microsoft-Windows-CodeIntegrity/Operational CodeIntegrity reports 'Invalid image hash' or 'Unsigned image' for new/updated binaries
  • NSM:Flow First-time egress from host after new install to unknown update endpoints

Linux Analytic 1481

1) Package manager or curl/wget installs/upgrades from non-approved repos or unsigned packages; 2) new ELF written into PATH directories or replacement of existing binaries/libraries; 3) first run leads to unexpected child processes or outbound connections.

  • auditd:SYSCALL execve, unlink
  • auditd:SYSCALL open, rename
  • journald:package dpkg/apt install, remove, upgrade events
  • NSM:Flow First-time egress to unknown registries/mirrors immediately after install

macOS Analytic 1482

1) pkg/notarization installs from atypical sources or with Gatekeeper/AMFI warnings; 2) new Mach-O written into /Applications or ~/Library paths or substitution of signed components; 3) first run from installer spawns unsigned children or exfil.

  • macos:unifiedlog installer or system_installd 'PackageKit: install succeeded/failed' with non-notarized or unknown signer
  • macos:osquery launchd, processes
  • macos:endpointsecurity write, rename
  • NSM:Flow New egress from app just installed to unknown update endpoints
