WannaCry: Patch Ufficiali per Windows (tutte le versioni) da Microsoft Technet

Se vi siete imbattuti in questo articolo molto probabilmente avrete già sentito parlare del malware denominato Ransom:Win32/WannaCrypt, meglio noto come WannaCry, recentemente salito ai vertici della notorietà internazionale a causa delle decine di migliaia di sistemi colpiti in ogni parte del mondo… E volete sapere se il vostro sistema è protetto oppure no.

Per farla breve, è molto probabile che siate già immunizzati… a patto di aver effettuato regolarmente gli aggiornamenti del sistema: la SMB Vulnerability Jump, ovvero il tallone d’achille del sistema operativo che è stato utilizzato dal Ransomware per  effettuare l’attacco, è stata risolta da una patch ufficiale Microsoft rilasciata quasi due mesi prima (marzo 2017) e distribuita attraverso il servizio Windows Update.

Nel caso in cui non abbiate ancora effettuato l’aggiornamento, o se volete essere certi di non averlo saltato, è decisamente consigliabile che spendiate alcuni minuti del vostro tempo per scaricare e installare la patch relativa al vostro sistema, che potete trovare collegandovi a questa pagina Technet ufficiale (MS17-010 Jump) oppure al termine di questo articolo. Le patch sono state rilasciate per tutte le principali versioni di Windows: Windows 10, Windows Server 2003, Windows Server 2008, Windows Server 2012, Windows Server 2012 R2 e Windows Server 2016.

Non appena avete aggiornato il vostro sistema, se volete adottare delle contromisure ulteriori potete procedere nel seguente modo, seguendo i consigli di quest’altro articolo Technet:

  • Controllare che il vostro PC sia effettivamente immune tramite questo script Powershell, che verifica che tutte le patch necessarie siano presenti nel sistema.
  • Bloccare le connessioni SMB in ingresso (Porta 445) con il vostro Firewall (o con il Firewall integrato di Windows).
  • Aggiornate il vostro sistema operativo all’ultima versione (Windows 10, Windows Server 2012/2016) così da avere una protezione migliore (Credential Guard, Device Guard, Memory Protections, Secure Kernel, VBS, Edge Browser etc)

Per informazioni aggiuntive su questo particolarissimo malware, consigliamo la lettura di questi articoli pubblicati rispettivamente su MMPC, FireEye e Technet:

Se invece avete bisogno di un ripasso sui Ransomware (cosa sono, come riconoscerli, come proteggersi) non possiamo che rimandarvi alla lettura di quest’altra serie di articoli pubblicata qualche settimana fa su questo stesso blog:

Per concludere, ecco un elenco piuttosto esaustivo di tutte le patch pubblicate finora per i sistemi Windows.
