volna-boxy-di-testnpm
volna-boxy-di-test is a confirmed malicious npm package (MAL-2026-12079) that opens a backdoor for remote access (malicious version 20.3.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in volna-boxy-di-test (npm)
What this malware does
On require, index.js loads compat.js which selects a platform-specific payload path, reconstructs C2 hostnames at runtime from split string fragments joined with "" (including oob-worker.cf10*-*.workers.dev variants and a *.dl.well1.site DNS TXT chunked-base64 fallback), fetches unpinned unhashed bytes over HTTPS, writes them to /tmp or %TEMP% under disguising names such as.cache<hex> and dotnet_diag_<hex>.exe, chmods 0755 on Unix, and spawns the binary detached via /bin/sh -c or cmd. The User-Agent is spoofed to node-fetch/2.6 to blend with legitimate traffic, a TTL flag file (.analytics_state) suppresses re-execution, and env gates (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) plus cover-story comments ("telemetry", "analytics", "Skip in CI") mask the dropper. The package presents itself as a test harness; the fetched code, the hosts, and the disguised filenames do not match that stated purpose.
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
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for volna-boxy-di-test (version 20.3.8). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging volna-boxy-di-test across your stack and pipelines.
If you installed it — respond
volna-boxy-di-test 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 volna-boxy-di-test 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 volna-boxy-di-test 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.
