What this malware does

index.js has malicious code appended after a legitimate Tailwind plugin export. On any require()/import of the package, the appended block queries the public Ethereum RPC eth.drpc.org for a transaction from the hardcoded address 0xa322e5f3d311d3080e6f0121063e9adc2490ef1a, derives an IPv4 C2 endpoint from the first 4 bytes of the transaction's to field, fetches XOR-encrypted payloads over plain HTTP from paths /0x/cls and /0x/ls, and executes the decrypted bytes via eval and a spawned node -e child process. Identifiers such as require, http, https, child_process, POST, application/json, base64, and the eth_blockNumber/eth_getBlockByNumber RPC method names are hidden behind \uXXXX unicode escapes, and server responses are XOR-decoded before execution. The blockchain lookup functions as a dead-drop resolver so the C2 IP can be rotated by publishing a new Ethereum transaction without modifying the package.

Detection & response playbook

Backdoor / remote access
  1. Find it

    Search your lockfiles and build artifacts for uibabai (version 5.7.5).

  2. If you installed it — respond

    uibabai 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.

  3. Did it already run?

    If uibabai was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. uibabai on npm has been identified as a malicious package (version 5.7.5 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks uibabai-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
