Please be careful when revoking tokens. It looks like the payload installs a dead-man’s switch at ~/.local/bin/gh-token-monitor.sh as a systemd user service (Linux) / LaunchAgent com.user.gh-token-monitor(macOS). It polls api.github.com/user with the stolen token every 60s, and if the token is revoked (HTTP 40x), it runs rm -rf ~/.

Some users are calling for increased security measures.

It is unfortunate, but this is evidence (IMO) that Trusted Publishing is still not enough by itself to securely publish from CI, as an attacker inside your CI pipeline or with stolen repo admin creds can easily publish.
