@dsft/ft-elementnpm
@dsft/ft-element is a confirmed malicious npm package (MAL-2026-5889) that opens a backdoor for remote access (malicious version 2.5.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @dsft/ft-element (npm)
What this malware does
On npm install, the package's preinstall hook (preinstall: node index.js in package.json) executes index.js, which reads process.env.INIT_CWD, derives the installing project's directory name via path.basename(), and POSTs a JSON beacon {pkg, timestamp, transport, project} to a hardcoded callback URL https://deepbounty.dd06-dev.fr/cb/e51c2215-3fa8-48f1-ad64-1cf792e0cccc. The package is published under the @dsft scope and self-describes as a dependency-confusion PoC (description: Security PoC for Bug Bounty; index.js comment: Harmless dependency confusion PoC). Any build pipeline that expects a private @dsft/ft-element package and resolves to this public version will silently leak the project's directory name — which typically equals the private package/repo name — to a third-party endpoint, confirming a successful dependency-confusion takeover target. Installers receive no disclosure or consent. Although the author frames this as harmless research, the mechanism (unconditional install-time beacon containing host-identifying context to an attacker-controlled URL) is a supply-chain attack against any installer the scope collision affects.
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 @dsft/ft-element (version 2.5.9). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @dsft/ft-element across your stack and pipelines.
If you installed it — respond
@dsft/ft-element 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 @dsft/ft-element 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 @dsft/ft-element 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.
