Our team is deploying continuous efforts to stop this however the service is being intermittently affected. In some cases, DDoS attacks are simply designed to cause disruption with those behind the attacks just launching them because they can. There are some SLP implementations that do not allow for registration of new services, leaving the amplification factor to a smaller fixed value. The bigger the response in relation to the request, the higher the amplification factor. Organizations should also have an incident response plan in place that clearly outlines procedures for mitigating SLP vulnerabilities, as well as procedures for communicating with users and stakeholders in case of an incident. However, most of the implementations that we have seen and tested do allow and are vulnerable to registration of spoofed services, thus enabling the massive 2200X amplification factor. Dark.fail tweeted on Friday that Empire was targeted with a DDoS (distributed denial of service) attack. DDoS attacks are becoming more frequent, more disruptive and increasingly include ransom demands, according to recent research.
