New York Post has been "hacked" by an employee. To protect themselves from insider threats, companies can deploy zero trust and restrict access. On October 27, the New York Post published a string of racist and sexist articles on its website. Fabricated news about politicians, such as pieces concerning racist comments of a New York City mayor, has been headlining the publication. more

We Must Keep Track of How Countries Will Confront Cybercrime in a New UN Convention

As a designated committee of experts prepares to draft a new treaty to combat the use of information and communications technologies in cybercrime at the UN in January 2022, it is paramount that other stakeholders oversee these discussions to avoid violating human rights on the Internet. This initiative was kickstarted by a 2019 resolution led by Russia and endorsed by other countries considered by many to behavior controversially on cybersecurity matters, such as China, Venezuela, Cambodia, North Korea, and others. more

Clarke and Knake’s “Cyberwar”

I just finished reading Richard Clarke and Robert Knake's book Cyberwar. Though the book has flaws, some of them serious, the authors make some important points. They deserve to be taken seriously. I should note that I disagree with some of my friends about whether or not "cyberwar" is a real concept. Earlier, I speculated that perhaps it might be a useful way to conduct disinformation operations, but it need not be so limited. more

Blocking a DDoS Upstream

In the first post on DDoS, I considered some mechanisms to disperse an attack across multiple edges (I actually plan to return to this topic with further thoughts in a future post). The second post considered some of the ways you can scrub DDoS traffic. This post is going to complete the basic lineup of reacting to DDoS attacks by considering how to block an attack before it hits your network -- upstream. more

Global Paradigms We Relied Upon Were Destroyed Overnight - How Prepared Are You for New Realities?

Unprecedented new Political and Cyber Security Threats are happening at a scale that has never been witnessed before. These threats are large and malicious enough to take down nuclear programs, render oil refineries inoperable, and take billion-dollar websites offline (not to mention smaller ones). Recent events confirm that NO ONE IS IMMUNE. Despite the obvious warning signs, Internet business stakeholders the world over continue to act as if nothing has changed, and seem unaware that global paradigms have undergone a seismic shift almost overnight. more

Maintaining Security and Stability in the Internet Ecosystem

DDoS attacks, phishing scams and malware. We battle these dark forces every day - and every day they get more sophisticated. But what worries me isn't just keeping up with them, it is keeping up with the sheer volume of devices and data that these forces can enlist in an attack. That's why we as an industry need to come together and share best practices - at the ICANN community, at the IETF and elsewhere - so collectively we are ready for the future. more

Black Frog: Next Generation Botnet, No Generation Spam Fighting

Black Frog -- a new effort to continue the SO-CALLED Blue Security fight against spammers. A botnet, a crime, a stupid idea that I wish would have worked -- News items on Black Frog. Blue Frog by Blue Security was a good effort. Why? Because they wanted to "get spammers back". They withstood tremendous DDoS attacks and abuse reports, getting kicked from ISP after ISP. ...The road to hell is filled with good intentions. Theirs was golden, but they got to hell, quite literally, non-the-less. ...When Blue Security went down, some of us made a bet as to when two bored guys sitting and planning their millions in some café would show up, with Blue Security's business plan minus the DDoS factor. Well -- they just did. more

Cyber-Terrorism Rising, Existing Cyber-Security Strategies Failing, What Are Decision Makers to Do?

While conventional cyber attacks are evolving at breakneck speed, the world is witnessing the rise of a new generation of political, ideological, religious, terror and destruction motivated "Poli-Cyber™" threats.

OARC-40: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held a 2-day meeting in February, with presentations on various DNS topics. Here are some observations I picked up from the presentations in that meeting... In a world where every DNS name is DNSSEC-signed, and every DNS client validates all received DNS responses, we wouldn't necessarily have the problem of DNS spoofing. Even if we concede that universal use of DNSSEC is a long time off ... more
