GEN:SID | 1:226 |
Message | DDOS Stacheldraht server response |
Summary | This event indicates that a Stacheldraht handler exists on the source host and an agent on the destination host.
|
Impact | Serious. A Distributed Denial of Service attack maybe in progress.
|
Detailed Information | The Stacheldraht DDoS uses a tiered structure of compromised hosts to coordinate and participate in a denial of service attack. There are "handler" hosts that are used to coordinate the attacks and "agent" hosts that launch the attack. When a host becomes a Stacheldraht agent it makes an initial contact with each of its known handlers. A handler should respond with an ICMP echo reply with an ICMP identification number of 667 and a string of "ficken" in the payload.
|
Affected Systems | Any Stacheldraht compromised host.
|
Attack Scenarios | A host on which a Stacheldraht agent has been installed attempts to contact the list of known handlers.
|
Ease of Attack | Simple. Stacheldraht code is freely available.
|
Corrective Action | Turn of all unnecessary services on hosts.
Upgrade to the latest patch level.
Use a packet filtering firewall to block inappropriate traffic to the network to prevent hosts from being compromised.
