0day "In the Wild"


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.

Active DNS

DNS | IP | Networks

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 "" .

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.

A similar active DNS project is Open INTEL which seems to be larger in scope and the data is publicly available.


Akamai provides aggregated data about the root servers. They provide the overall amount of DNS queries, trends, and IPv4/IPv6 query ratios.

All the collected measurements can be found in the RIPE Atlas Daily Archives. The blog post gives some more details.

RIPEstat: Providing open data and insights for Internet resources

Autonomous Systems | BGP | DNS | Networks | Tools

RIPEstat is a network statistics platform by RIPE. The platform shows data for IP addresses, networks, ASNs, and DNS names. This includes information such as the registration information, abuse contacts, blocklist status, BGP information, geolocation lookups, or reverse DNS names. Additionally, the website links to many other useful tools, such as an address space hierarchy viewer, historical whois information, and routing consistency checks.

Root Servers

DNS | Tools

Overview page for the DNS root servers. It contains links to general news and all the supporting organizations.

The website features a map with all geographic locations. It contains information about locations, IPv4/IPv6 reachability and IP addresses.

Each root server has its own subdomain in the form of It contains access to historical performance data like:

  • Size and time of zone updates
  • RCODE volume
  • query and response sizes for UDP and TCP
  • traffic volume (packets per time)
  • Unique sources

Routing Information Service (RIS)

BGP | DNS | Networks | Tools

Different information regarding reachability and connectiveness of ASs.

ROV Deployment Monitor

BGP | Networks | RPKI

The Route Origin Validation (ROV) Deployment Monitor measures how many AS have deployed ROV. It uses PEERING for BGP annoucements and uses BGP monitors to see in which ASs the wrong announcements are filtered. A blogpost at APNIC describes it in more detail.

RPKI Browsers

Networks | RPKI | Tools

These websites allow you to browser the valid RPKI announcements. They show which address ranges are covered by RPKI and who the issuing authority is.

RSSAC002 DNS Root Server Data


RSSAC002 describes measurements for DNS root servers. It collects data, such as the load time, rcode volumes, traffic volume, and unique sources. The data is collected daily and goes back to 2013.

The data is also available in a git repository, which is not always up-to-date. Internet-Wide Scan Data Repository

Certificates | DNS | IP | Networks

The website contains no usable data anymore and only links to empty pages on Censys.

The website used to host many free Internet scans of different kinds. It included historical data and activly maintained datasets.

Shadowserver Scanning Project

Networks | DNS

The Shadowserver Scanning projects performs regular Internet wide scans for many protocols. They scan for four main types of protocols:

  1. Amplification protocols, e.g., DNS or NTP
  2. Botnet protocols, e.g., Gameover Zeus or Sality
  3. Protocols that should not be exposed, e.g., Elastic Search, LDAP, or RDP
  4. Vulnerable Protocols, e.g., SSLv3

The website is a great resource to get general statistics about the protocols, like the number of hosts speaking the protocol, their geographic distribution, associated ASNs, and the historic information.


Certificates | DNS | IP | Networks

Shodan performs regular scan on common ports.

Access is free, but requires registration. More results can be gained with a paid account.

System Security Cirrcus

Paper Writing | Security

The System Security Cirrcus by Davide Balzarotti presents many statistics about the Top-4 security conferences, such as authors and affiliations.

TeleGeography Map Gallery

Maps | Networks

TeleGeography provides different maps about the Internet. They contain information about submarine cables, global traffic volume, latency, internet exchange points. The data for the Submarine Map and the Internet Exchange Map can also be found on GitHub in text format.

Transient Execution Attacks


The website lists all known speculation side channel attacks. Each attack contains information about the attacked buffer, the affected vendors, and working state. They are sorted into a hierarchy. Each attack is also linked to proof-of-concepts and the academic papers.


Autonomous Systems | BGP | Networks | Tools

vizAS by APNIC shows the connectiveness between different ASs split by countries. It is usefull to find the ASs which are most central in the graph.

Vulnerable (Docker) Containers

CTF | Docker

The 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.

WAND Active Measurement Project

Autonomous Systems | DNS | Networks | Tools

AMP is a system designed to continuously perform active network measurements between a mesh of specialist monitor machines, as well as to other targets of interest. These measurements are used to provide both a view of long-term network performance as well as to detect notable network events when they happen.

The project is run with a custom client and server software. The measurement results can be viewed on the website. It includes traceroutes, latencies (DNS, HTTP, ICMP, TCP), HTTP page sizes, and packet loss. The software is available as open source.

World Country Information

Many different metadata about countries, such as name, country code, languages. It also has a geojson of the country outline and the flags.

x86 Instruction Set

Cheatsheet | x86 | CTF

These websites provide reference documentation of the x86 instruction set:

Zonefiles: Domain Lists


The 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 only reports over 6 million domains.
