BadNeighbor vulnerability a nightmare scenario for enterprises
October 2020 by Jeff Costlow, CISO at ExtraHop
Among the Windows 10 vulnerabilities Microsoft announced
yesterday, the #BadNeighbor vulnerability stands out, posing a potential
nightmare scenario for enterprises. With a severity score of 9.8 out of
10, the remote code execution (RCE) vulnerability would allow an
attacker to run malware or launch a denial of service (DoS) attack.
Even worse, the attack has widespread potential: Gartner estimated that
one billion PCs — or 80% of all PCs in use [1] — will be running
Windows 10 this year.
Jeff Costlow, CISO at
ExtraHop comment:
Dubbed #BadNeighbor, the Windows 10 vulnerabilities Microsoft unveiled
on October 13th would allow a hacker to exploit a remote code execution
(RCE) vulnerability to run malware or launch a denial of service (DoS)
attack. Because of the nature of these attacks, it is extremely
difficult to detect them using traditional security solutions like EDR
and SIEM.
Security solutions focused on network detection and response have the
unique ability to see these sorts of network attacks. Because this
vulnerability attacks the IP stack in the kernel, other security
solutions (like EDR and SIEM) are unlikely to detect these particular
exploits. EDR solutions will only see the attack once the payload is
executed, and logs in a SIEM are unlikely to detect this vulnerability
because messages (ICMP) are rarely logged.
Any organization using Windows 10 is vulnerable and should deploy the
patch immediately to avoid compromise of their Windows 10 systems.
