The dataset contains NTP DDoS reflection attack traffic. These attacks are triggered by the attackers via sending monlist queries with spoofed source IP addresses to vulnerable hosts running NTP. These vulnerable hosts respond with a list of last clients (up to 600), typically producing large replies compared to the small queries. README FRGP_SSDP_Reflection_DDoS_Attack_Traffic-20140930 2014-09-30 2014-09-30 UNKN About 3 hours of DDoS attack traffic to a victim in the form of Argus flows. Most of the attack traffic is UDP Simple Service Discovery Protocol (SSDP) traffic. The traffic also includes ICMP and other UDP protocols traffic. The flows are on a 10Gb/s link between a regional and a content ISP. These attacks are triggered by the attackers via UPnP/SSDP discovery requests with spoofed source IP addresses to vulnerable hosts running SSDP. README Service_Enumeration_Google-20130818 2012-10-17 2013-08-18 5.72G This dataset enumerates all known google front-end IP addresses, and clusters them into datacenters and sites.

README T-DNS-experiments-20140324 2013-11-01 2014-01-01 18.34M Experiments measuring performance of using DNS over TCP and TLS README UniformAttack_Traces_Generated20070821-20041202 2004-12-02 2004-12-03 2.69G This trace set contains 16 trace pairs created in August 2007 using background trace data recorded in December 2004. Each trace pair has the same uniform attack, and different background traffic. The background traffic bitrates are 196 Mbps and 320 Mbps, from the D12_02T01_56 and D12_02T15_56 traces, respectively. The uniform attack increases exponentially from 1 Mbps to 250 Mbps. The two streams were merged with the uniform attacks using the stream_merger application. The scripts and instructions are available in http://www.isi.edu/ant/software as DAG trace generator. This dataset supersedes and corrects UniformAttack_traces-20070115 http://wiki.isi.edu/predict/index.php/LANDER:UniformAttack_traces-20070115 README as_to_org_mapping-20101019 2010-10-19 2010-10-19 9.25M This dataset provides a mapping from ASes to organizations, i.e., identifies which ASes belong to which organizations. We determined the mapping by automatic clustering methods. The general idea of the methods is to cluster ASes by their attributes found in WHOIS databases obtained from five Regional Internet Registries (RIR). README as_to_org_mapping_inferred_truth-20110901 2011-09-01 2011-09-01 252.77K This dataset provides a mapping from ASes to organizations, i.e., identifies which ASes belong to which organizations. We determined the mapping by manual inspection of RIR whois information, using AS names and external information (company web pages, wikipedia, etc.) to infer a feasible ground truth. This dataset comprises 109 organizations and their 4019 ASes in total. README as_to_org_mapping_inferred_truth-20100507 2010-05-07 2010-05-07 38.85K This dataset identified the ASes beloging to 9 large Internet organizations. We determined these ASes by manual inspection of RIR whois information, using AS names and external information (company web pages, wikipedia, etc.) to infer a feasible ground truth. README as_to_org_mapping_subsidiary_linkage-20101019 2010-10-19 2010-12-31 2.52G This dataset provides a linking between ASes and company subsidiaries. It is derived from WHOIS database and Form 10-K filings. The linking is useful to associate ASes that belong to different subsidiaries of the same organization. We determined the links by automatic record linkage algorithms and followed by manual verification and pruning. The general idea is to compare how similar the name of an AS is to the name of a subsidiary. Due to the inaccuracy of automatic linkage, we then manually verify and prune the links for selected most important organizations. README attack-tcpsyn-20061106 2006-11-06 2006-11-06 97.90M This tcp syn attack was captured by a large hosting service.

README survey_validation_tcpvsicmp-20071009 2007-10-09 2007-10-14 539.59M During this experiment 1 million of random allocated IP addresses were probed using a single ICMP ECHO_REQUEST and a single TCP SYN on port 80. The order of probing was ICMP, then TCP for the first half of probed addresses and then TCP followed by ICMP for the second half. A slightly modifed version of NMAP was used. Output of NMAP as well as tcpdump of all sent/received packets are included in this dataset. README survey_validation_usc-20070813 2007-08-13 2007-08-23 251.45G These traces are collected at the Los Nettos ISP and show the vast majority of all traffic to and from USC. README tcp-reset-study-20071107 2007-11-07 2007-11-08 115.00G trace collected at a provider link in order to study the prevalence of tcp resets in the Internet. README usc_lander_ongoing_tracing_scrambled-20120501 2012-05-01 2020-01-01 UNKN Scrubbed (user data removed) and scrambled (fully anonymized) packet traces taken at a border router between USC and Los Nettos. These traces can be taken on-demand. There is a possibility for the user to run a pre-processing script that can pre-screen traces for interesting data or network events. When applying, please specify desired start and end date/time.
