La sottorete di Vincent \u00e8 finita nella lista Level 3, in cui il blocco \u00e8 effettuato sulla base dei numeri di sistemi autonomi e comprende intere sottoreti da cui sono stati attivati ripetutamente i rilevatori di spam per diversi indirizzi. Di conseguenza, il provider M247 ha disattivato l'annuncio di una delle sue reti in BGP, sospendendo di fatto il servizio.       <\/p>\n<p>Il problema \u00e8 che le modalit\u00e0 fittizie <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/\"   title=\"servers\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1914\">servers<\/a>   UCEPROTECT, che si spacciano per relay aperti e registrano tentativi di invio di posta attraverso di esse, includono automaticamente gli indirizzi nella lista di blocco sulla base di qualsiasi attivit\u00e0 di rete, senza verificare la condizione della connessione di rete. Un metodo simile di inserimento in lista di blocco viene utilizzato anche dal progetto Spamhaus.     <\/p>\n<p>Per finire nella lista di blocco \u00e8 sufficiente inviare un pacchetto TCP SYN, che potrebbe essere sfruttato da malintenzionati. In particolare, poich\u00e9 non \u00e8 richiesta una conferma bidirezionale della connessione TCP, \u00e8 possibile inviare un pacchetto tramite spoofing con un indirizzo falso <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/lir\/ipv4\/\"   title=\"Indirizzi IP\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"678\">Indirizzi IP<\/a> e innescare l'inserimento nella lista di blocco di qualsiasi host. Simulando attivit\u00e0 da diversi indirizzi, si pu\u00f2 ottenere l'escalation del blocco ai livelli Level 2 e Level 3, che implementano il blocco sulla base delle sottoreti e dei numeri dei sistemi autonomi.       <\/p>\n<p>La lista Level 3 \u00e8 stata originariamente creata per combattere i provider che incoraggiano attivit\u00e0 dannose dei clienti e non rispondono alle segnalazioni (ad esempio, hosting creati appositamente per ospitare contenuti illegali o per servire spammer). Alcuni giorni fa UCEPROTECT ha modificato le regole di inserimento nelle liste Level 2 e Level 3, portando a una filtrazione pi\u00f9 aggressiva e a un aumento delle dimensioni delle liste. Ad esempio, il numero di voci nella lista Level 3 \u00e8 aumentato da 28 a 843 sistemi autonomi.     <\/p>\n<p>Per contrastare UCEPROTECT \u00e8 stata proposta l'idea di utilizzare lo spoofing degli indirizzi con IP dall'intervallo dei sostenitori di UCEPROTECT durante la scansione. Di conseguenza, UCEPROTECT ha incluso gli indirizzi dei propri sponsor e molti altri innocenti nelle proprie basi, creando problemi nella consegna delle email. Anche la rete CDN della compagnia Sucuri \u00e8 finita nella lista di blocco.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
