DNS: Transaction Spoofing (3)
This signature triggers when it detects attempts to exploit a known vulnerability against most DNS servers (both Windows and Unix/Linux). Attackers can spoof DNS replies by sending multiple crafted packets to DNS servers. A successful attack can result in redirected traffic to unintended locations. There is a related threshold to this attack - sc_dns_mismatch_rate.
