Η ομάδα United States Computer Emergency Readiness Team (US-CERT) προειδοποιεί με μια ανακοίνωσή της για ένα νέο exploit kit κιτ που αναπτύχθηκε από τη hacking ομάδα Shadow Brokers Το νέο exploit kit είναι available for sale and targets Windows systems.
Earlier this week, rumors were released that wanted Shadow Brokers to try to sell a zero-day Windows for 750 Bitcoin, and US-CERT says it should take action immediately.
In its publication, the US-CERT states that the zero-day exploit targets a vulnerabilityπου είναι είναι διαθέσιμη σε όλα τα συστήματα των Windows μέσω του χαρακτηριστικού Server Message Block (SMB). Μια επιτυχής επίθεση επιτρέπει σε έναν εισβολέα να αποκτήσει ευαίσθητες information from the affected systems.
The team recommends Windows administrators to disable SMB v1 and block all versions of SMB at the network boundary by locking the doors TCP 445 along with all associated protocols on UDP ports 137-138 and the door TCP 139, for all devices, even if the above measures could obviously have an impact on the smooth operation of the system.
For the time being, however, it is important to note that there is still no confirmation of this zero-day in Windows, by Microsoft itself that does not seem to know that there is an unpatched vulnerability.
