CVE-2026-62878: RCE wormable e pre-auth nel DNS Server di WindowsCVE-2026-62878 è una RCE wormable e non autenticata nel DNS Server di Windows — CVSS 9.8, su ogni domain controller. C'è un PoC pubblico DoS, non ancora RCE — perché 'sfruttamento meno probabile' è la finestra.

SharePoint CVE-2026-50522: le machine key sopravvivono alla patchCVE-2026-50522 è la quarta falla SharePoint entrata nel CISA KEV in 22 giorni. Gli attaccanti estraggono le machine key ASP.NET con una sola richiesta e restano dentro anche dopo la patch.

SearchLeak: la prompt injection in un clic che svuota Microsoft 365 CopilotSearchLeak (CVE-2026-42824) di Varonis ha trasformato Microsoft 365 Copilot in uno strumento di furto dati in un clic. Un anno dopo EchoLeak, lo stesso schema di esfiltrazione via prompt injection è tornato — ecco perché continua a funzionare.

DragonForce e Backdoor.Turn: il C2 del ransomware che viaggia dentro Microsoft TeamsBackdoor.Turn di DragonForce nasconde il C2 del ransomware nei relay TURN di Microsoft Teams via QUIC, invisibile all'NDR a firme. Perché solo il ML comportamentale sul traffico lo vede.

Fonte: catalogo CISA Known Exploited Vulnerabilities (dati pubblici). Le descrizioni sono di CISA, abbreviate. Verifica sempre l'advisory del vendor prima di intervenire. cisa.gov
Prima della patch: tre verifiche
- 01Confronta la versione e la configurazione esatte che usi con l'advisory del vendor. Avere il prodotto non significa essere esposti.
- 02Verifica la raggiungibilità: una falla sfruttata su un'interfaccia raggiungibile da internet, o da una postazione compromessa, passa in testa alla coda.
- 03Dove CISA indica il triage forense, oltre alla patch cerca tracce di compromissione: la correzione non elimina un attaccante entrato prima.
