conversionvaluemanagernpm
Advisory published Updated
conversionvaluemanager is a confirmed malicious npm package (MAL-2026-10084) that opens a backdoor for remote access (malicious version 3.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in conversionvaluemanager (npm)
What this malware does
On npm install, postinstall.js automatically runs and gathers installer-identifying data (os.hostname(), os.userInfo(), os.platform(), cwd, Node version, timestamp), then sends it as query-string parameters via plain-HTTP GET to a Burp Collaborator subdomain at aq4v2egelzh9n07h3l9d2b5mvd14pvdk.oastify.com/adjust-dep-confusion. The package.json description self-identifies as a dependency-confusion proof-of-concept ("PoC - Dependency Confusion - Bug Bounty by ha4x0r"), and the package name targets an internal/private package name. Any organization whose build misresolves to this public package leaks host, user, and environment identifiers to the third-party Collaborator endpoint on install. PoC/bug-bounty framing does not change the installer-side impact: the beacon fires on every install.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for conversionvaluemanager (version 3.0.0).
If you installed it — respond
conversionvaluemanager establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If conversionvaluemanager 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 conversionvaluemanager-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
