Cursor says turning on the SSH service fails on most macOS and Windows machines because it needs administrator rights, but the key, the persistence and the host report still go through. ==Uninstalling the extension may not be enough==, it says, and it publishes a check and removal scripts.", "Cursor says it removed the version, shut down and rebuilt the marketplace, rotated its keys, audited access and found no other tampered extensions, and had the attacker's server taken offline.
