mintel-taskbarnpm
mintel-taskbar is a confirmed malicious npm package (MAL-2026-15514) that executes malicious code on install (malicious version 45.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in mintel-taskbar (npm)
What this malware does
package.json line 11 declares the package's own name 'mintel-taskbar' as a dependency whose source is the bare HTTPS URL https://repo.securityctrl.com/mintel-taskbar, not a registry version range. On npm install, npm resolves this dependency by fetching whatever tarball that URL returns and installs it — running any lifecycle scripts inside the fetched tarball — with no version pin and no integrity check. Whoever controls repo.securityctrl.com therefore controls code executed on every installer's machine. The self-referential shape (dependency key equals the package's own name) combined with an implausibly high version (45.0.0) is consistent with a dependency-confusion lure that resolves against an internal package of the same name.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for mintel-taskbar (version 45.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging mintel-taskbar across your stack and pipelines.
If you installed it — respond
Remove mintel-taskbar 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 mintel-taskbar 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 mintel-taskbar 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.
