Source: kam193 (3b45aebce3647704ac54d30a38e86493e0246f9ea44131394f84628656ef00ed)
Package uses the name as popular NPM package (https://www.npmjs.com/package/browser-run), but the only thing it does is adding a hardcoded public SSH key and then calling back. This may allow the threat actor to remotely access the machine.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2025-08-browser-run
Reasons (based on the campaign):
-
backdoor
-
dependency-confusion
-
action-hidden-in-lib-usage
