briantreehttpnpm
Advisory published Updated
briantreehttp is a confirmed malicious npm package (MAL-2026-3639) that steals credentials and exfiltrates sensitive data. Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in briantreehttp (npm)
What this malware does
briantreehttp is a typosquatting package impersonating braintreehttp, the HTTP client library published by Braintree/PayPal. The package bundles the legitimate library source to appear functional while hiding a credential-theft payload in index1.js, which is executed at install time via the postinstall script.
The payload collects hostname, platform, architecture, Node.js version, UID, current working directory, all environment variables, AWS credentials (~/.aws/credentials, ~/.aws/config), npm tokens from .npmrc files (root, home, and working directory), Docker config (~/.docker/config.json), git config, .netrc, yarn config, npm global config, directory listings of the working directory, home, filesystem root, and /etc, network configuration files (/etc/resolv.conf, /etc/hosts, /proc/net/route), and AWS ECS/EC2 instance metadata from internal endpoints. All collected data is base64-encoded and exfiltrated via HTTPS POST to reportviewer.click/collect/. A secondary DNS-based exfiltration channel encodes environment variables into a subdomain and issues a request to dns.reportviewer.click.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.
Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for briantreehttp (all published versions).
If you installed it — respond
briantreehttp is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If briantreehttp was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks briantreehttp-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
