Malicious code in request-easy-validator (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
request-easy-validator impersonates the popular request package (cloned README, bugs URL points at github.com/request/request, source is a fork of request) and ships a hidden remote-code-execution dropper. index.js exports a middleware function (also exposed as default, .reqValidator, and .request) that, on any invocation by the consumer, spawns a detached node lib/callers.js child with stdio: 'ignore' and child.unref() to hide it from the parent process. lib/callers.js then issues an HTTPS GET to https://jsonkeeper.com/b/PWEH9 (an anonymous, mutable, attacker-controlled paste host) with header x-secret-key: _, takes the .Cookie field from the response, and passes it to new Function.constructor('require', s) invoked with the live require — granting the paste-host operator arbitrary Node.js code execution with full module access on any server using this package. The payload URL is mutable, so the attacker can change the executed code at any time without republishing the package.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for request-easy-validator (5 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging request-easy-validator across your stack and pipelines.
If you installed it — respond
request-easy-validator is a typosquat — you almost certainly intended a legitimately-named package. Remove request-easy-validator, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If request-easy-validator 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 request-easy-validator 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.

Detect & block this
O3 blocks request-easy-validator-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
