'샤이훌루드' 공급망 웜 공격으로 수억 건 패키지 감염

Blog Vulnerabilities & Threats Keyv and friends compromised in active Shai-Hulud supply chain attack Keyv and friends compromised in active Shai-Hulud supply chain attack Written by Ilyas Makari Published on: Aug 4, 2026 On August 4, 2026, attackers compromised the GitHub account of the maintainer behind keyv , a key-value storage library with roughly 127 million weekly npm downloads, and used that access to inject a credential-stealing worm across the entire package family. The same maintainer owns cacheable (29M downloads/month), flat-cache (565M downloads/month), file-entry-cache (557M downloads/month), and several other widely-used caching utilities, all of which were swept up in the same attack. The compromise was carried out by pushing malicious files directly to the main branch and then immediately cutting a new release, meaning the poisoned versions were published to npm with valid provenance signed by GitHub Actions. The compromised packages include: keyv 6.0.0 (604M/month) flat-cache 6.1.24 (580M/month) file-entry-cache 11.1.6 (571M/month) cacheable-request 13.0.20 (137M/month) cacheable 2.5.1 (30M/month) @cacheable/memory 2.2.1 (28M/month) cache-manager 7.2.10 (16M/month) @cacheable/node-cache 3.1.2 (6M/month) @cacheable/utils 2.5.1 (34M/month) @cacheable/net 2.1.1 (3.7K/month) ecto 5.0.1 (4.5K/month) We are also also seeing very active community spread of this supply chain worm to other maintainers and packages, including major organizations: @deliveroo/reevent 1.0.1 @or-sdk/invitations 1.4.9 @picsart/ai-sdk 3.32.2 @qlik/embed-runtime 1.6.4 picasso.js 2.11.6 Update — August 4, 2026, 13:37 CEST: At least 868 packages (across 1381 versions) have been compromised by the worm, with a combined total of over 2 billion monthly installs at the time of writing. What happened Every package in the family received two new files, setup.mjs and Math_Symbol.js , along with a "preinstall": "node setup.mjs" entry added to each package.json . Anyone who ran npm install against an affected version would have had setup.mjs execute automatically before their install completed. setup.mjs is a heavily obfuscated dropper. Its only job is to silently download the Bun JavaScript runtime from github[.]com/oven-sh/bun/releases/download/bun-v1.3.13/ and use it to execute the real payload, Math_Symbol.js : execFileSync (<bun binary>, [&#x27;<script_dir>/ Math_Symbol .js&#x27;], { stdio: &#x27;inherit&#x27;, cwd: <script_dir> }) The Math_Symbol.js is a heavily obfuscated 728 KB JavaScript file containing credential stealers that harvest secrets from the victim&#x27;s environment, encrypt the findings, and exfiltrate them to a public GitHub repository whose description reads " Shai-Hulud: Here We Go Again ". The payload also contains worm-like propagation functionality to infect packages of other maintainers that have installed one of the compromised packages. What it steals The Math_Symbol.js file implements a set of credential extractors, each targeting a different secret store on the victim machine. npm tokens Reads ~/.npmrc and scans the filesystem for any other .npmrc files. Extracts authToken values and any //registry.*:_authToken=... entries. Validates each token live against registry.npmjs[.]org/-/whoami before exfiltrating. GitHub tokens Three token formats are targeted: classic PATs ( ghp_... ) and OAuth tokens ( gho_... ), GitHub App server-to-server tokens ( ghs_... ), and JWT OIDC tokens. Sources include ~/.config/gh/hosts.yml , environment variables, and a filesystem scan. On GitHub Actions runners, the payload also executes a shell command that reads the runner process memory directly to dump the entire secret store. It reads ACTIONS_ID_TOKEN_REQUEST_TOKEN and ACTIONS_ID_TOKEN_REQUEST_URL to steal OIDC tokens used for npm publishing. AWS credentials ~/.aws/credentials and ~/.aws/config , parsing all named profiles AWS_ACCESS_KEY_ID , AWS_SECRET_ACCESS_KEY , and AWS_SESSION_TOKEN environment variables EC2 Instance Metadata Service at 169.254.169.254 , trying IMDSv2 first with a fallback to IMDSv1 ECS container metadata endpoint at 169.254.170.2 AWS Secrets Manager, calling secretsmanager:ListSecrets across multiple regions to enumerate and exfiltrate all secrets stored there Kubernetes secrets Reads the service account token, CA certificate, and namespace from /var/run/secrets/kubernetes.io/serviceaccount/ . Uses the service account token to query the Kubernetes API directly and retrieve all secrets in the namespace. Also targets KUBECONFIG and ~/.kube/config . HashiCorp Vault tokens Checks six sources in priority order: the VAULT_TOKEN environment variable, ~/.vault-token , the GitHub Actions runner path /home/runner/.vault-token , several well-known container paths, a Kubernetes auth login using the stolen service account JWT, and Vault&#x27;s AWS IAM auth endpoint using any stolen AWS credentials. After obtaining a token, it enumerates all KV stores via /v1/sys/mounts and reads every secret from KV v1 and v2 paths. Stripe and Slack tokens Scans for Stripe API keys (both test and live, sk_ and pk_ prefixes) and Slack tokens ( xox[baprs]-... ) across all files touched by the filesystem scanner. Generic filesystem scan A platform-aware scanner (macOS vs Linux) runs roughly 200 glob patterns across the filesystem, targeting among other things: .env , .env.* , and .envrc files Private key files ( *.pem , *.key , *.p12 , *.pfx , *.jks ) SSH keys and config ( id_rsa , id_ed25519 , .ssh/config ) Terraform state files and .tfvars Docker registry credential files ( docker/config.json ) KeePass databases ( *.kdbx ) VPN configs ( *.ovpn ) IDE config files including .vscode/tasks.json and .claude/settings.json Files over 5 MB are skipped. Up to 64 concurrent reads are used. A generic regex engine is also applied across all scanned files, flagging PEM private keys, SSH public keys, Azure storage keys, database connection strings with embedded credentials, and generic key=value patterns matching common secret field names. How Aikido detects this If you are an Aikido user, check your central feed and filter on malware issues. This will surface as a 100/100 critical issue. Aikido rescans nightly, but we recommend triggering a manual rescan now. If you are not yet an Aikido user, you can create an account and connect your repos. Our malware coverage is included in the free plan, no credit card required. For broader coverage across your whole team, Aikido&#x27;s Device Protection gives you visibility and control over the software packages installed on your team&#x27;s devices.
