Historic datasets (from 2014 onwards) for the .nl TLD. Datasets are available in JSON format.
Datasets cover information about:
Google Project Zero tracks a list of zero day exploits discovered in the wild. They track public resources to find uses of zero days and collect them in this spreadsheet. The spreadsheet contains data since 2014. Their blog provides an introduction and explanation of the spreadsheet.
Historical DNS database. Access can be requested for academic use.
Activly queries many DNS records, e.g., .com zone.
It can contain information not in DNSDB, if the information was never seen by a resolver.
It does not contain all informatin, as some domains may be unknown to the project and thus cannot be crawled.
It uses popular zones, domain lists (e.g., Alexa, blacklists) and other domain feeds.
They normally maintain a rolling 14-day window.
Copy files (for date 2017-10-05) (ddos@gladbeck):
sftp -B1024000 -C -rp "activedns@kokino.gtisc.gatech.edu:active-dns/20171005/" .
The data is encocded in AVRO format, which can also be parsed as JSONL. Python has a AVRO library. AVRO schema:
{
"namespace": "astrolavos.avro",
"type": "record",
"name": "ActiveDns",
"fields": [
{"name": "date", "type": "string"},
{"name": "qname", "type": "string"},
{"name": "qtype", "type": "int"},
{"name": "rdata", "type": ["string", "null"]},
{"name": "ttl", "type": ["int", "null"]},
{"name": "authority_ips", "type": "string"},
{"name": "count", "type": "long"},
{"name": "hours", "type": "int"},
{"name": "source", "type": "string"},
{"name": "sensor", "type": "string"}
]
}
Some more information about some fields that are unique to that schema. The IPs in Authority IP are the collection of the authority name server IPs that replied to our query. We gather all the IPs that gave us the same answer for an entire day and concatenate them on the same field, mostly in order to reduce the number of records that we have to keep. The only field that might be slightly confusing, is the "hours" field. This is a 24bit integer that encodes the time of day we saw this RR for date date (for example, 000000000000000001000010 = 18:00 and 23:00). Another important thing to keep in mind, is NXDOMAINs. A resolved QNAME does not exist when both the rdata and ttl fields are equal to null. If rdata exists but ttl is null then the record was part of the glue of the DNS packet and not in the answer section.
Akamai provides aggregated data about the root servers. They provide the overall amount of DNS queries, trends, and IPv4/IPv6 query ratios.
APNIC gathers many different statistics and offers them on their website. However, they provide way more data then it might initially look like, since many of the datasets are not linked from their main page.

Detailed 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.
