New Whois Survey Findings
Dave Piscitello was one of four principal investigators of a joint M3AAWG and the Anti-Phishing Working Group (APWG) survey,
ICANN, GDPR, and the WHOIS: A Users Survey — Three Years Later.
The survey asked cyber investigators and anti-abuse service providers to describe
ongoing impacts of ICANN's implementation of the EU GDPR, the Temporary Specification for gTLD Registration Data (Temporary Specification, adopted in May 2018).

Andy Malis co-authors more RFCs on Deterministic Networking
Interisle partner Andy Malis participates in the Internet Engineering Task Force's Deterministic Networking (DetNet) project,
focused on deterministic data paths providing bounds on latency, loss, jitter, and high reliability. DetNet is publishing
RFCs on this topic, with Andy as co-author on some, including
RFC 9023: Deterministic Networking (DetNet) Data Plane: IP over IEEE 802.1 Time-Sensitive Networking (TSN),

Academic Research Corroborates Interisle Study Findings
A large-scale systematic measurement study
to quantify the changes made by WHOIS providers in response to the GDPR was presented at The Network and Distributed System Security Symposium (NDSS) on 22 February.
Using a collection of 1.2 billion WHOIS records spanning two years and software they developed to automate compliance checking, the researchers found levels of WHOIS
redaction beyond what the GDPR would require that corroborate the findings of Interisle's recent
WHOIS Contact Data Availability and Registrant Classification Study.

Interisle Launches the Cybercrime Information Center
Cybercrime—phishing, pharming, botnets, malware, and spam—threatens every Internet user. To fight cybercrime we need to know how criminals acquire
and use the Internet resources that enable their criminal activity. The Cybercrime Information Center
(CIC) will gather and publish the facts about cybercrime. By publishing its measurement data, the Center will identify the sources and mechanisms of
cybercrime, as defined in the Council of Europe's Budapest Convention
on Cybercrime. Researchers, governments, businesses, and others will be able to use CIC data to evaluate the policies and practices that attract and encourage

WHOIS Contact Data 2021
Interisle Consulting Group has published a major new research report, the
WHOIS Contact Data Availability and Registrant Classification Study.
The report presents an in-depth analysis of how contact data for Internet domain names–which make all web sites, email, and apps work–has disappeared from public
access, impeding cybercrime investigation, consumer protection, Internet security, and online commerce.

Phishing Landscape 2020
Interisle Consulting Group has published a major new research report,
Phishing Landscape 2020: A Study of the Scope and Distribution of Phishing.
Interisle collected data about phishing attacks from four respected threat intelligence sources over a period of three months, learning about more than 100,000 newly discovered phishing sites.
This extensive data set formed the basis for an in-depth analysis of how and where criminals are getting the resources they use to scam Internet users, and points to better ways to fight phishing.
Interisle releases report on domain registration data
Internet users of all kinds rely on public domain name registration data services ("Whois") to obtain accurate and up-to-date operational and registration information
for vital and legitimate purposes. Over the last two years, access to domain name registration data has been drastically curtailed as a result of ICANN policies,
data privacy laws, and due to practices by registrars and registry operators.
Interisle studied domain registration data, measuring the effectiveness and impact of ICANN's registration data access
policies and procedures by examining the practices of 23 registrars, which collectively sponsor more than two-thirds of the registrations in the generic top-level
domains (gTLDs). It determined whether they comply with ICANN's policies and related contractual obligations, and also to the European Union's General Data Protection Regulation (EU GDPR).
