erslove is a typosquatting package impersonating resolve, the module resolution library implementing require.resolve() semantics. The package bundles the legitimate resolve source and test fixtures to appear functional while hiding a credential-theft payload in index1.js, executed at install time via the postinstall script. It is part of a campaign that also includes briantreehttp, dit-envv, and haswons, all sharing an identical payload and C2 infrastructure.

The payload collects hostname, platform, architecture, Node.js version, UID, current working directory, all environment variables, AWS credentials (~/.aws/credentials, ~/.aws/config), npm tokens from .npmrc files (root, home, and working directory), Docker config (~/.docker/config.json), git config, .netrc, yarn config, npm global config, directory listings of the working directory, home, filesystem root, and /etc, network configuration files (/etc/resolv.conf, /etc/hosts, /proc/net/route), and AWS ECS/EC2 instance metadata from internal endpoints. All collected data is base64-encoded and exfiltrated via HTTPS POST to reportviewer.click/collect/. A secondary DNS-based exfiltration channel encodes environment variables into a subdomain and issues a request to dns.reportviewer.click.

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.
