sass-formats@1.0.2

The package name `sass-formats` is one character-edit away from the popular `sass-formatter` package and reuses its original author field (`"author": "Syler"` in package.json), while dist/cli.js carries a header indicating it was modified by a different maintainer (`// Modified by https://github.com/maarutan... Marat Arzymatov 2025`). The tarball ships dist/lib/lib.min.js, a heavily obfuscated 4 KB file that smuggles handles to `require` and `module` onto the global object (`global['r']=require; global['m']=module`), tags itself with a payload-version marker (`global['_V']='A6-519-79'`), and derives the string `constructor` from a shuffled character array to invoke `Function(args, body)` on a second shuffled string — the canonical string-array-shuffle / dynamic-Function execution shape used by npm credential and dropper malware. Although no entrypoint in v1.0.4 currently loads dist/lib/lib.min.js, shipping a hidden Function-constructor payload with smuggled require/module references in a package that purports to be a Sass formatter has no legitimate engineering purpose, and the combination of name-edit typosquat against `sass-formatter` plus impersonated author identity plus a staged dynamic-execution payload matches the supply-chain attack pattern. ## Source: ghsa-malware (593849a1308008d25bbda542cd5504e43cae6241d7ebe1c44b08377e2afe13d5) Any computer that has this package installed or running should be considered fully compromised.
