Message | DDOS Trin00 Attacker to Master default mdie password |
Summary | This event is generated when a trinoo DDoS attacker host communicates with a master host.
|
Impact | Attempted DDoS. If the listed source IP is in your network, it may be a trinoo attacker. If the listed destination IP is in your network, it may be a trinoo master.
|
Detailed Information | The trinoo DDoS uses a tiered structure of compromised hosts to coordinate and participate in a distributed denial of service attack. At the highest level, attackers communicate with masters to direct them to launch attacks. An attacker may communicate with a master via TCP destination port 27665 with a string of "killme" in the payload. This string is a default mdie password.
|
Affected Systems | Any trinoo compromised host.
|
Attack Scenarios | A trinoo attacker will communicate with masters to direct them to launch attacks.
|
Ease of Attack | Simple. trinoo code is freely available.
|
Corrective Action | Perform proper forensic analysis on the suspected compromised host to discover the means of compromise.
Rebuild a confirmed compromised host.
Use a packet-filtering firewall to block inappropriate traffic to the network to prevent hosts from being compromised.
