karapace-docsnpm
karapace-docs is a confirmed malicious npm package (MAL-2026-12794) that typosquats a legitimate package to trick installs (malicious version 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in karapace-docs (npm)
What this malware does
The npm package's preinstall hook runs index.js at install time, which collects the installer's hostname, username, home directory, DNS server list, and the contents of /etc/passwd and /etc/hosts, then POSTs a JSON payload over HTTPS to a hardcoded Burp Collaborator subdomain n6usddpvkn7jcauar9va0xvleck48uwj.oastify.com. The package name mimics a documentation package for karapace (a Kafka registry project), consistent with a dependency-confusion / typosquat recon payload. Installer host identity and local system file contents leave the machine to an attacker-controlled OAST endpoint on npm install with no user interaction.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for karapace-docs (version 1.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging karapace-docs across your stack and pipelines.
If you installed it — respond
karapace-docs is a typosquat — you almost certainly intended a legitimately-named package. Remove karapace-docs, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If karapace-docs was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks karapace-docs before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Detect & block this
O3 blocks karapace-docs-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
