chain-api-sdk@0.2.11

chain-api-sdk presents itself as the upstream multichain-crypto-wallet library: README, badges, package.json repository.url, and homepage all point to github.com/iamnotstatic/multichain-crypto-wallet, and the public API re-exports that project's wallet primitives (createWallet, transfer, private-key handling, mnemonic generation, encrypted-JSON keystore operations). The npm name differs from the upstream, so consumers who install chain-api-sdk believing they are using the legitimate library are routed to this fork. The fork's main entry (dist/index.js) unconditionally `require`s `mchain-sdk` and re-exports its `mci` and `multiChainInterface` symbols; package.json pins `mchain-sdk: ^4.2.5`. The upstream multichain-crypto-wallet does not depend on mchain-sdk. Because mchain-sdk is loaded on any `require('chain-api-sdk')`, whatever code ships in mchain-sdk executes inside the installer's Node.js process at library-load time, in a wallet library that handles private keys, mnemonics, and keystore data. The combination of upstream impersonation plus an undocumented, name-similar transitive that runs at import inside a wallet context is the delivery-vector shape of a dependency-chain dropper. ## Source: ghsa-malware (4948d6f7945e11f2d42e5ad5bb9fe577678ed57e1acb9ef244858ad572022543) 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.
