The successor program to the notorious Zango spyware Toolbar is being used to target users of Mozilla’s Firefox with fake browser updates, a security company has alleged. According to a warning put out by eSoft, the reprised Hotbar app, run as of May last year by a new entity called Pinball Corp, is being fed to users via a fake but convincing Firefox update page. The update page – which users would come to through a search engine for the latest updates – looks identical to the genuine page in everything bar the version it is claiming to offer and some misspelling.
