The attacker (npm user **mr.4nd3r50n**) published 139 scoped packages at the inflated version `99.99.99`, which resolves ahead of any private registry version via npm's default version resolution, silently hijacking installs of internal packages.\n\nOn installation, the `postinstall` hook executes `scripts/postinstall.js`. The script waits 3 seconds (sandbox evasion), then downloads an OS-specific second-stage JavaScript payload from `https://oob.moika.tech/payload/{mac|win|linux}.js`, writes it to a temporary file (`._cloudplatform-single-spa_init.js` in the system temp directory), and spawns it as a detached Node.js process that continues running after npm exits. The payload exfiltrates the full `process.env` (environment variables including secrets, tokens, and credentials), along with hostname, username, platform, architecture, and working directory, to the C2 endpoint `https://oob.moika.tech/report`. If the second-stage download fails, a fallback beacon containing the same system details is sent to the same endpoint.\n\n---\n_-= Per source details.

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.\n","affected":[{"package":{"ecosystem":"npm","name":"@cloudplatform-single-spa/dataplatform"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}]}}],"references":[{"type":"REPORT","url":"https://safedep.io/oob-moika-tech-dependency-confusion-campaign/"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-2m8v-gg54-p274"}],"credits":[{"name":"SafeDep","type":"FINDER","contact":["https://safedep.io"]}],"database_specific":{"malicious-packages-origins":[{"source":"ghsa-malware","sha256":"0bbd87d7349e92b79e923658e3de60085e85391c00b87babc8f03ffd5d57cd87","import_time":"2026-05-29T23:43:53.253442081Z","id":"GHSA-2m8v-gg54-p274","modified_time":"2026-05-29T22:54:06Z","ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}]}]}}
