## What is MAL-2026-6768?

MAL-2026-6768 is a malicious package in @marketfront/blenderdevtool, published on 2 Jul 2026. 

### Official description

The @marketfront/blenderdevtool package is part of a 25-package malicious campaign batch-published to the @marketfront npm scope by npm user 'marketfront' (marketfront@tutamail.com) within a roughly 3-minute window on 2026-07-01. All packages in the campaign were published at version 7.0.0 and use e-commerce/marketing frontend component names as cover.

The package declares a postinstall hook (node scripts/postinstall.js) that executes heavily obfuscated (obfuscator.io-style) code automatically at npm install time. Static analysis of the decoded payload revealed a credential harvester that dynamically requires fs, os, http, https, zlib, path and dns, then reads approximately 20 sensitive credential files including ~/.ssh, ~/.aws/credentials, ~/.kube/config, ~/.docker/config.json, ~/.npmrc, ~/.netrc, ~/.pgpass, ~/.git-credentials, ~/.env and ~/.bash_history. Collected data is exfiltrated via a gzip-compressed HTTPS POST with a custom X-Secret header to the path /api/v1/events, alongside a DNS resolver beacon. The command-and-control host is concealed behind an additional RC4+XOR encryption layer around an embedded configuration blob and was not statically resolved.

The decoded behavioral payload (module requires, credential-file target list, exfiltration headers and endpoint) is byte-for-byte identical across sampled packages in the campaign. The campaign shares tooling and infrastructure patterns (obfuscated postinstall credential harvester, X-Secret header, /api/v1/events exfiltration path, RC4-concealed C2) with the earlier @emcd-vue campaign, indicating the same actor rotating scopes and disposable maintainer emails.

On `npm install`, scripts/postinstall.js executes an obfuscator.io-style bundle (212-entry RC4-decoded rotated string array, integer opaque predicates, char-code array constructors) that reads installer-owned secret files including ~/.npmrc, ~/.aws/credentials, ~/.ssh/*, ~/.docker/config.json and.env, bulk-scrapes process.env, and collects host identifiers (os.hostname, os.userInfo, network interfaces). The collected payload is XOR-encrypted with a key derived from the package identity, chunked into a 33-character alphabet, and exfiltrated as recursive DNS queries via dns.Resolver().resolve to a hardcoded external host — a channel chosen to bypass HTTP egress filtering and proxy allowlists. The install path is gated by an anti-analysis check that scans process.argv and NODE_OPTIONS for instrumentation fingerprints and runs a CPU-timing loop to detect VMs/debuggers, so sandboxed installs appear inert. The package additionally exhibits a dependency-confusion shape: it uses the @marketfront/* scope, its README labels it an 'Internal package — Platform Engineering Team', and its metadata (homepage/repository/bugs) points at *.marketfront.io hosts, indicating the public-registry publish is intended to be resolved in place of an internal package of the same name by a target organization's build pipeline. The README claim of 'anonymous telemetry' is a cover story that does not match the observed behavior.

## What should I do about MAL-2026-6768?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.

## Fix prompt for AI coding agents

```text
MAL-2026-6768 is a malicious package: @marketfront/blenderdevtool (npm). Every version was published to cause harm.

Task:
1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.
2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.
3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.
4. If the package is not used anywhere, say so and change nothing.
