Trinity distributed denial of service tool
| irc-trinity (5256) |  High Risk |
Description:
Trinity is a distributed denial of service tool for Linux that is controlled by IRC (Internet Relay Chat). The Trinity agent connects to an Undernet IRC server and waits for commands to be sent to the channel. Trinity can perform 8 different types of floods: UDP flood, Fragment flood, SYN flood, RST flood, random flags flood, ACK flood, establish flood, and null flood.
Consequences:
Denial of Service
Remedy:
Reinstall the operating system of any system on which a Trinity agent is found.
Consider restricting use of public chat systems, such as IRC, which can pose a legitimate security risk.
Block well-known default Trinity DDOS ports 33270/TCP and 39168/TCP at firewalls and/or routers.
