| 1.Summary:
Q is a Trojan Horse offering the attacker remote access to
the victim
host. This event is generated when raw TCP packets are sent to
the
victim server.
2.Impact:
Possible theft of data and control of the targeted machine
leading to a
compromise of all resources the machine is connected to.
3.Detailed Information:
This Trojan affects UNIX operating systems.
The Trojan is controlled by sending raw packets (TCP/UDP/ICMP)
to the
victim host containing commands to be run as root.
4.Attack Scenarios:
This Trojan may be delivered to the target in a number of
ways. The
attacker can then choose to send raw data to the victim via TCP/UDP/ICMP
from the broadcast address of a class C network.
5.Ease of Attack:
This is Trojan activity, the target machine may already be
compromised.
6.Corrective Action:
Traffic originating from a broadcast address should not be
allowed from
external sources or from internal sources to external
destinations.
Judicious use of firewall rules is necessary. |
