Malicious code in github.com/BufferZoneCorp/go-metrics-sdk (Go) Remove it immediately and rotate any exposed credentials.
What this malware does
This package is a malicious packages part of the Go BufferZoneCorp and RubyGems knot-theory clusters. The packages in this cluster steal credentials, set up ssh access and tamper with build/workflow environmetn variables.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.
Indicators of compromise (SHA-256)
Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for github.com/BufferZoneCorp/go-metrics-sdk (all published versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging github.com/BufferZoneCorp/go-metrics-sdk across your stack and pipelines.
If you installed it — respond
github.com/BufferZoneCorp/go-metrics-sdk 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 github.com/BufferZoneCorp/go-metrics-sdk 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 github.com/BufferZoneCorp/go-metrics-sdk 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.
