DatasetDetailed analysis on a 10 year dataset of IoT binaries and their security features. The Cyber ITL focussed on which compiler and toolchain hardenings the vendors use.
CITL identified a number of important takeaways from this study:
- On average, updates were more likely to remove hardening features than add them.
- Within our 15 year data set, there have been no positive trends from any one vendor.
- MIPS is both the most common CPU architecture and least hardened on average.
- There are a large number of duplicate binaries across multiple vendors, indicating a common build system or toolchain.

CTF | CVE | DatasetThe GitHub repository collects CVEs and proof-of-concept (PoC) exploits for them. It is a good resource to play around with sample exploits.
https://vulnerablecontainers.org/
CTF | Dataset | DockerThe website lists docker containers from Docker Hub with known vulnerabilities in it. The top 1000 docker containers from Docker Hub are regularly scanned with Trivy and the results reported here.
A similar tool to scan for vulnerable containers is Clair scanner.

DNS | Dataset | NetworkThe website provides download access to domains in many TLDs. Most lists are updated daily. However, not all of the lists seem complete. For example, DENIC reports that they manage over 17 million domains, whereas zonefiles.io only reports over 6 million domains.
caniuse.rs shows which library functions were stabilized in which Rust version.
dnsdumpster.com fetches a lot of DNS information belonging to one domain. It checks the authorative name servers, which records exist, and where the servers are located.

DNS | DNSSEC | Dataset | NetworkDnsthought list many statistics about the resolvers visible to the .nl-authoritative name servers. The data is gathered from the RIPE Atlas probes. There is a dashboard which only works partially.
Raw data access is also available.

Dataset | NetworkIODA is a project by CAIDA to use different data sources to detect macroscopic internet outages in realtime. It measures the internet activity using BGP, darknets, and active probing. The website provides a realtime feed and a historical view of outages.
Online interface to find a libc database by function offsets. They are powered by the libc-database repository.
