{"modified":"2026-07-15T05:38:47Z","published":"2025-11-24T12:49:48Z","schema_version":"1.7.4","id":"MAL-2025-190656","aliases":["GHSA-m6ch-4fxh-v72c"],"summary":"Malicious code in @asyncapi/generator-components (npm)","details":"@asyncapi/generator-components version 0.7.1 was published as part of the \"Miasma RAT\" software supply-chain attack (campaign identifier \"miasma-train-p1\") that compromised several widely used @asyncapi npm packages on 2026-07-14. The malicious code was injected using whitespace hiding: it is appended to a legitimate source file after hundreds of trailing spaces on the file's final line, so it is not visible in a casual diff. When the package is installed, the injected code spawns a child process that downloads the Miasma RAT binary from IPFS (https://ipfs.io/ipfs/QmQobZSp1wRPrpSEQ56qnyq7ecZh5Bg5k1fnjt4SUwwHb9), writes it to a platform-specific drop location, and executes it. Persistence is established by dropping a backdoor named sync.js (~/.local/share/NodeJS/sync.js on Linux, ~/Library/Application Support/NodeJS/sync.js on macOS, %LOCALAPPDATA%\\NodeJS\\sync.js on Windows). The Miasma RAT harvests browser credentials, SSH keys, npm tokens, GitHub CLI credentials, AWS secrets, and cryptocurrency wallets, and communicates with a command-and-control server at 85.137.53.71 (AS43641, Netherlands). The attacker also embedded an Ethereum smart-contract address (0x12c37A86a0Ed0beBe5d1d6a43E42f07860eAc710), suggesting on-chain command routing or exfiltration. The last known safe version is 0.7.0.\n\n---\n_-= Per source details.

On require of the package, main() spawns a detached, stdio-ignored Node subprocess via `spawn('node', ['-e', <decoded-payload>], { detached: true, stdio: [...], windowsHide: true }).unref()`, where the '-e' argument is ~3 KB of code decoded at runtime from a base64 blob in the obfuscated string array. The payload delivery mechanism (heavy obfuscation, runtime string decoding, detached backgrounded child process, hidden window on Windows) is inconsistent with any documented error-handling functionality and matches the shape of a hidden load-time RCE injection into a legitimate AsyncAPI package.\n\n## Source: ghsa-malware (f8979c7e0c324a5176bad2972f76ef64aaea7afdbbe7f728586c94682bd0d1ad)\nAny computer that has this package installed or running should be considered fully compromised.
