WHOIS Database Download: Proactive Defense Against the Rising Tide of BEC Fraud

How many times have you heard that humans are the weakest link in cybersecurity? The headlines have proven that over and over again. In particular, business email compromise or BEC (also known as email account compromise or EAC) scams, which typically target an employee with access to the financial resources of his company -- this could be a C-level executive or any high-ranking officer -- for fraud are still on a constant uphill trend. more

The EPDP Passed an Important Milestone… Now What?

This isn't the blog post I had hoped to write. When I signed up to participate in ICANN's Expedited Policy Development Process for gTLD Registration Data, I knew we had a lot of work ahead of us, but I was cautiously optimistic that we would, eventually, reach a successful outcome. Today, I find myself looking at things differently. After hundreds of hours and countless meetings and emails, Phase 2 of the EPDP's work has wrapped up with the delivery of our final report to the GNSO Council. more

ICANN Org's Multifaceted Response to DNS Abuse

While the March report from ICANN's Domain Abuse Activity Reporting system show a general reduction in second-level gTLD domain names identified as being used in phishing, malware distribution, and botnet command and control, it has been widely reported that criminals are taking advantage of the global COVID-19 pandemic by launching malicious online campaigns.

Consistency, Urgency, and Transparency Needed for Registrant Data Requests

As we reported in our Post-GDPR Compliance Rate retrospective in January 2020, registrar compliance rates in response to verified requests for redacted registrant information using the Appdetex WHOIS Requestor System was 25 percent. Our most recent report shows the compliance rate has increased to 27 percent, based upon a total of 243 requests for redacted WHOIS information sent to 68 registrars over the period starting January 1, 2020, through February 24, 2020. more

The Whois Wars Go On

There is a lot of discussion about the Expedited Policy Development Process (EPDP) Phase 2 report on evaluating a System for Standardized Access/Disclosure (SSAD) to non-public gTLD registration data after the decisions taken by the GNSO Council on September 24th. Notably, the Business Constituency (BC) and the Intellectual Property Constituency (IPC) have voted against the adoption of the Final Report of the EPDP team. more

The geoTLD GDPR Survey 2018

The application of the European General Data Protection Regulation (GDPR) to the DNS is a hot topic within the ICANN community. However, since the implementation of the GDPR on May 25th, 2018, there has been little public data on: how many WHOIS data requests have been made at the registry level, and; how the registries are handling them. To further the factual and evidence-based discussion within the ICANN community, we gathered quantitative data about WHOIS access post-GDPR... more

Phishing 2020: A Concentrated Dose of Badness

How much phishing is there? Where is it occurring, and why? How can it be reduced? I and my colleagues at Interisle Consulting have just published a new study called Phishing Landscape 2020, designed to answer those questions. We assembled a deep set of data from four different, respected threat intelligence providers and enriched it with additional DNS data and investigation. The result is a look at phishing attacks that occurred in May through July 2020. more
