bnpl-blocks-mobile-bnpl-image-plus-textnpm
bnpl-blocks-mobile-bnpl-image-plus-text is a confirmed malicious npm package (MAL-2026-12993) that opens a backdoor for remote access (malicious version 35.3.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-mobile-bnpl-image-plus-text (npm)
What this malware does
On require of the package, compat.js assembles remote endpoint hostnames from split string arrays (e.g. oob-worker.cf10x-*.workers.dev) and includes a DNS TXT-record base64 fallback channel over c.<domain> and numbered subdomains of dl.wel1.ru. It downloads a platform-specific binary from those attacker-controlled hosts with no hash or signature verification, writes it to a temp path under a masquerading name (dotnet_diag.exe on Windows,.cache_ on Unix), chmods it 0755, and spawns it detached via cmd.exe /c start /b or /bin/sh -c. The dropper runs on module load with a TTL stamp to suppress re-execution. Behaviors observed include platform gating, cover-story naming, string-concatenation obfuscation of the C2 hosts, and a covert DNS TXT-record fallback for endpoint resolution.

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 bnpl-blocks-mobile-bnpl-image-plus-text (version 35.3.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bnpl-blocks-mobile-bnpl-image-plus-text across your stack and pipelines.
If you installed it — respond
bnpl-blocks-mobile-bnpl-image-plus-text 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 bnpl-blocks-mobile-bnpl-image-plus-text 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 bnpl-blocks-mobile-bnpl-image-plus-text 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.
