Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (bd94f9aefc7090d1260bb8123fd1bd78f4fd973b9d00c2423fbc13ea9799699b) Package @k18k/[email protected] is a darwin-x64 platform-specific sub-package, following the standard npm pattern for distributing prebuilt native binaries per OS/architecture (optionalDependencies selected by the parent SDK package based on process.platform/process.arch). The tarball contains a small number of files and no install, preinstall, postinstall, or prepare lifecycle scripts were observed. No network calls, no reads of installer secrets (~/.aws, ~/.ssh, ~/.npmrc, environment variables), no fetch-and-execute, no silent-relay, and no persistence behavior were observed. ## Source: ghsa-malware (0b430da8eb1d9a15b74f4abfe412db5106d498cf018c3a611e2d151a993c7819) 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.
