Message | DDOS Stacheldraht client check skillz |
Summary | This event is generated when a Stacheldraht agent attempts to contact a known handler. |
Impact | This indicates that a Stacheldraht agent may exist on the source host and a handler may exist on the destination host. |
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. Once a host becomes a Stacheldraht agent, it will attempt to contact a list of known handlers using an ICMP echo reply with an ICMP identification number of 666 and a string of "skillz" in the payload. |
Affected Systems | Any Stacheldraht compromised host. |
Attack Scenarios | A compromised host that has become a Stacheldraht agent will attempt an initial communication with all known handlers. |
Ease of Attack | Simple. Stacheldraht 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. |
