Software Supply-Chain Security

Protecting the integrity of software dependencies and artifacts against compromise via maintainers, registries and build pipelines — trust replaced by verification.

Also known as: supply chain attack, supply-chain attack, software supply chain security, supply chain risk, provenance, provenance attestation, SBOM, Software Bill of Materials (SBOM), chain of custody, verification (over trust), transferable maintainership, dependency confusion, transitive dependencies, social engineering, RAT (Remote Access Trojan), Cyber Resilience Act, EU Cyber Resilience Act (CRA)

Leading Open Source Author Calls for Verification over Trust in Software Supply Chains
Matt Saunders · 2026-03
verification (over trust)Actively checking that software artefacts contain only what they claim to contain, using cryptographic signatures, reproducible builds, and independent auditing — as opposed to relying on the reputation of the producer

Matt Saunders · 2026-03
Software Bill of Materials (SBOM)A machine-readable inventory of every component in a software artefact, which can be signed and verified to provide a chain of custody

Matt Saunders · 2026-03
chain of custodyAn unbroken, cryptographically verifiable record from source code through build to delivered artefact, establishing that no tampering occurred

EU Cyber Resilience Act (CRA)European regulation opening enforcement in September 2026 that can block product sales (not just impose fines) for non-compliance with SBOM and security requirements

dependency confusionAn attack technique that exploits package resolution logic to substitute malicious packages for legitimate internal ones
The Axios supply chain attack used individually targeted social engineering
Simon Willison · 2026-04-01
supply chain attackCompromising a widely-used software dependency at the source (maintainer credentials) so that downstream consumers unknowingly pull malicious code.

Simon Willison · 2026-04-01
social engineeringA multi-step impersonation campaign — cloned company, fake Slack, staged video call — designed to build enough trust that the target installs attacker-controlled software.

Simon Willison · 2026-04-01
RAT (Remote Access Trojan)The specific malware installed during the fake meeting that gave attackers persistent access to the maintainer's machine and credentials.
Attacker Bought 30 WordPress Plugins on Flippa and Backdoored All of Them
Steef-Jan Wiggers · 2026-04-01
supply-chain attackCompromising software by infiltrating its distribution or maintenance chain rather than exploiting a vulnerability in the code itself — here specifically via purchasing maintainership.

Steef-Jan Wiggers · 2026-04-01
transferable maintainershipThe ability to buy or assume control of a package's commit access, reputation, and update pipeline through marketplace transactions or social engineering, inheriting users' implicit trust.

Steef-Jan Wiggers · 2026-04-01
provenance attestationCryptographic proof linking a published package to its source code and build process, as implemented by npm — a countermeasure WordPress has not adopted.

Simon Willison · 2026-04-10
supply chain attackAn attack where a malicious dependency is injected into a widely-used software package by compromising a maintainer's credentials through social engineering
The Trump administration's AI doomer moment
Casey Newton · 2026-05-05
supply chain riskA legal designation the Trump administration applied to Anthropic after it refused to amend its Pentagon contract to allow 'all lawful use' — used as a punitive tool that now conflicts with the same administration's desire to use Anthropic's technology.

provenance (for decision making)A queryable, branching audit trail in the graph linking an idea, to spec, to every human-agent back-and-forth intervention, to the merged PR, to production — captured continuously as a 'flywheel' where each action is written to the graph and then summarized.
