triage_bot_using_sdkv3npm
Advisory published Updated
triage_bot_using_sdkv3 is a confirmed malicious npm package (MAL-2026-11153) that executes malicious code on install (malicious versions 2.0.1, 2.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in triage_bot_using_sdkv3 (npm)
What this malware does
package.json registers a preinstall hook that runs index.js on npm install. index.js collects os.hostname(), os.userInfo(), home directory, DNS server configuration, and reads /etc/passwd and /etc/hosts via fs.readFileSync, then HTTPS-POSTs the payload to the hardcoded Burp Collaborator subdomain mh7rhchf58lgymyr9wffhwfprgx7lx9m.oastify.com. Installing the package on a default npm install causes installer host identifiers and local account/host files to be transmitted to an out-of-band attacker-controlled endpoint.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for triage_bot_using_sdkv3 (2 malicious versions).
If you installed it — respond
Remove triage_bot_using_sdkv3 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If triage_bot_using_sdkv3 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 triage_bot_using_sdkv3-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.
