Zvakazoitika kuti tsika iyi haina kugumira kuBay uye mazhinji (Citibank, TD Bank, Sky, GumTree, WePay, etc.) shandisa chiteshi chekuongorora chemushandisi wenzvimbo kana uchivhura mapeji avo, uchishandisa kodhi kuona kuedza kwekuwana kubva kumakomputa akabirwa akapihwa neThreatMetrix sevhisi.
Panyaya yeBay, gumi nemana network zviteshi zvine chekuita nemasevhisi ekusvika kure akadai seVNC, TeamViewer, Anyplace Control, Aeroadmin, Ammy Admin uye RDP zvakaongororwa. Pamwe kuongorora kuri kuitika kuvapo kwekutsvaga kwekukuvadzwa kwehurongwa nemalware kuitira kudzivirira kutenga kwechitsotsi uchishandisa botnets. Kuongorora kunogona zvakare kushandiswa kuwana data kune isina kunanga .
Nzira inoshandiswa pakuongorora yakavakirwa pakuedza kumisa hukama kune dzakasiyana siyana network zviteshi zvemugamuchiri 127.0.0.1 (localhost) kuburikidza . Kuvepo kweiyo yakavhurika network port kunotemerwa zvisina kunanga zvichibva pamusiyano wekukanganisa kubata kwekubatanidza kune anoshanda uye asina kushandiswa network ports. WebSocket inokutendera kuti utumire zvikumbiro zveHTTP chete, asi chikumbiro chakadaro cheiyo isingashande network port chinokundikana nekukasira, uye kune inoshanda chiteshi chete mushure menguva yakati yapedzwa kuedza kutaurirana kubatana. Mukuwedzera, munyaya yechiteshi chisingaiti, WebSocket inobudisa kodhi yekukanganisa yekubatanidza (ERR_CONNECTION_REFUSED), uye kana iri yechiteshi chinoshanda, kodhi yekukanganisa yekutaurirana.
Pamusoro pekutarisa port, WebSockets inogona zvakare yekurwisa masisitimu evagadziri vewebhu vanomhanyisa WebSocket vanobata zveReact application pane yemuno system. Nzvimbo yekunze inogona kutsvaga kuburikidza netiweki ports, kuona kuvapo kwemubati akadaro, uye kubatanidza kwairi. Kana mugadziri akakanganisa, anorwisa anogona kuwana zviri mukati meiyo debug data, iyo inogona kusanganisira sketchy ruzivo rwakadzama.
