The Modern Encryption Debate: What’s at Stake?

The debate around encryption has become a hot topic in a world where communications are increasingly becoming digital. The modern encryption debate is a complex and nuanced issue, with many players from different backgrounds trying to influence the conversation. The question of balancing the need for national security with the right to privacy has been a matter of public debate for years. Only recently has the issue been framed in terms of encryption, but the discussion is certainly not new. more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

The Hack Will Be a Costly Affair for Optus

More and more information is becoming available about the breach of Optus (Australia's second-largest telco). It looks like the hacker is more of an amateur than a professional criminal or a "state actor." This makes the hack even more worrisome. It looks as though Optus didn't have its security house in order. This makes the issue all the more painful for the company. It will dent its reputation, and customers could become somewhat wary about dealing with the company. more

The Continued Rise of Phishing and the Case of the Customizable Site

We’ve noted in previous CSC studies that phishing continues to be an extremely popular threat vector with bad actors and shows no signs of subsiding in part, because of the COVID–19 pandemic and the rise in popularity of remote working. Indeed, the most recent figures from the Anti-Phishing Working Group (APWG) show that the numbers of phishing attacks are higher than ever before, with the quarterly total of identified unique phishing attacks exceeding 1 million for the first time in Q1 2022, and over 600 distinct brands attacked each month. more

Four Steps to an Effective Brand Protection Program

Internet use has become ever more pervasive. With around five billion global users, it generates an economy of around 15% of global gross domestic product (GDP); that's around $15 trillion and is a figure that's growing 2.5 times faster than GDP itself. This makes the internet an attractive channel for infringers. Phishing and other fraud tactics, selling counterfeit goods online, and digital piracy are primary areas of concern. more

Hijacked IP Addresses

From time to time, a party can get out of control. Raucous celebration can become careless, even destructive. Combine a critical number of young people, a certain amount of beer and lots of music and damage often happens. Partygoers leave a mess behind them. The same thing happens to some IP addresses. Malicious actors use IP addresses properly registered to someone else. more

Registration Patterns of Deceptive Domains

A key requirement for a bad actor wanting to launch a brand attack is the registration of a carefully chosen domain name. The most convincing infringements frequently use a domain name that's deceptively similar to that of the official site of the target brand. This allows a variety of attacks to be executed, including phishing attacks... more

Cyberhygiene Requires Critical Thinking

At his farewell speech in August outgoing, Telstra CEO Andy Penn mentioned that the cyber threat has never been as serious as the present. He mentioned the deteriorating geopolitical situation and the big shift in how criminals operate in the cyber domain. One thing is for sure is that in order to enjoy all the positives resulting from the digital economy, we need to be far more vigilant about the barrage of information that we are receiving and/or have access to. more

Businesses Beware: Cybersecurity Awareness Varies Based on Job Function

Businesses should consider bumping phishing as an urgent concern in their cybersecurity agendas. To those still unacquainted, "phishing" refers to the use of fake emails, messages, and websites that fool users into giving up access to accounts and information or into installing malware through attachments. It has become quite rampant over recent years. Attackers are using the method as a primary means to breach defenses, and with good reason: they work. more

The Latest OEWG on ICTs Report: Thoughts and Recommendations

At the end of July, the Open-ended Working Group (OEWG) on ICTs -- which is currently discussing how states should and shouldn't behave in cyberspace - concluded its third meeting, which falls in the middle of its four-year mandate (ending in 2025). Below, we provide a summary of what happened, reflections on the outcomes and implications (the good and the bad), and some practical recommendations for stakeholders and governments to consider ahead of the next meeting. more

Visit of US House Speaker Pelosi to Taiwan Has Little Impact on Network Infrastructures

I'm writing this from Taipei, where I have lived in peace for over 10 years. Sadly I learned that during this week, intermediate-range ballistic missiles (operated by China) have flown far above the capital of Taiwan and that five of them have landed in the waters of Japan's exclusive economic zone (EEZ). This provocative live-firing drill came as a direct response from China following Pelosi's visit. more

Solving the “Fake Twitter Profile” Problem Using DNS

Recently, an article I wrote for Bitcoin Magazine talked about how we can use DNS underscore scoping to better abstract Lightning addresses and even create a de facto specification that could work on any resource (like a wallet or a smart contract) across all blockchains. more

Where Domain Security Meets the Supply Chain Crunch

Over the last two years, we've all faced supply shortages on items we previously never thought could be in short supply. Most recently, the baby formula and semiconductor markets were hit. Before that, supply chain attacks on Colonial Pipeline and JBS Foods showed us that an attack on one company through a singular point of compromise has the potential to disrupt an entire network of connected companies, products, partners, vendors, and customers. more

IP Address Blocking

A network can fence its own IP addresses or block specific external ones from access. Administrators frequently block access to their own IP addresses to bar unwanted access to content. Individual IPs or blocks of IPs may also be blocked due to unwanted or malicious behavior. IP address blocking prevents a specific IP address or group of IP addresses from connecting with a server, computer, or application. more
