UCSD Network Telescope Daily Randomly and Uniformly Spoofed Denial-of-Service (RSDoS) Attack Metadata

This dataset contains meta-data of the randomly spoofed denial-of-service attacks inferred from the backscatter packets collected by the UCSD Network Telescope. It is aggregated from the raw Telescope data using the criteria described in the paper Inferring Internet Denial-of-Service Activity (2006) by Moore et al. This dataset is updated every day, and contains data starting October 1st 2008.

Data Description

The UCSD Network Telescope consists of a globally routed, but lightly utilized /9 and /10 network prefix, that is, 1/256th of the whole IPv4 address space. It contains few legitimate hosts; inbound traffic to non-existent machines - so called Internet Background Radiation (IBR) - is unsolicited and results from a wide range of events, including misconfiguration (e.g. mistyping an IP address), scanning of address space by attackers or malware looking for vulnerable targets, backscatter from randomly spoofed denial-of-service attacks, and the automated spread of malware. CAIDA continously captures this anomalous traffic discarding the legitimate traffic packets destined to the few reachable IP addresses in this prefix. We archive and aggregate these data, and provide this valuable resource to network security researchers.

To generate this RSDoS Attack Metadata dataset, we process 5-minute intervals of the raw telescope data extracting the response packets sent by victims of randomly and uniformly spoofed Denial-of-Service attacks (backscatter packets). Activity that related to the same victim is summarized in an 'attack vector', following the definitions and methodology described by Moore et al. (2006). We continue to update the attack vectors as long as related activity is still observed.
Once an attack completed, we record the accumulated statistics. We also geolocate the targeted IP address using NetAcuity Edge Premium Edition data and determine its origin AS using Routeviews Prefix-to-AS mappings (pfx2as) data.
For more information please see the RSDoS documentation.

Caveats that apply to this dataset

This dataset and the types of worm and denial-of-service attack traffic contained therein are representative only of some spoofed source denial-of-service attacks. Many denial-of-service attackers do not spoof source IP addresses when they attack their victim, in which case backscatter would not appear on a telescope. Attackers can also spoof in a non-random fashion, which will incur an uneven distribution of backscatter across the IPv4 address space, and may cause backscatter traffic to miss any telescope lenses. Note that the telescope does not send any packets in response, which also limits insight into the traffic it sees.

Data Access Policy

In 2021 CAIDA completed an NSF-funded CI-SUSTAIN project "Sustainable Tools for Analysis and Research on Darknet Unsolicited Traffic" (STARDUST). NSF’s expectation is that this funding has enabled CAIDA to sustain Telescope data collection, curation, and sharing through users' contributions. We are now undertaking efforts to put in place the mechanisms that allow such contributions. This includes service agreements and data licensing for academic and commercial data use, as well as new data access options. If you are interested in finding more information about the access options and pricing please fill out and submit the CAIDA UCSD Network Telescope Datasets Request Form.
