Message | DDOS mstream handler to agent |
Summary | This event is generated when a DDoS mstream handler directs an mstream agent to begin an attack against a specified target.
|
Impact | |
Detailed Information | The mstream DDoS uses a tiered structure of compromised hosts to coordinate and participate in a distributed denial of service attack. There are "handler" hosts that are used to coordinate the attacks and "agent" hosts that launch the attack. A handler can direct a particular agent to attack a target. It directs the agent by sending it a UDP packet to destination port 10498 with a string of "stream/" in the payload. The target IP and duration of the attack will also be included in the payload.
|
Affected Systems | Any mstream compromised host.
|
Attack Scenarios | After a host becomes an mstream agent, it will likely be directed to participate in a DDoS attack. |
Ease of Attack | Simple. mstream 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.
