Are Phishing and Malware Separate Threats?

Phishing is when bad guys try to impersonate a trusted organization, so they can steal your credentials. Typically they'll send you a fake e-mail that appears to be from a bank, with a link to a fake website that also looks like the bank. Malware offers another more insidious way to steal your credentials, by running unwanted code on your computer... I like VeriSign's characterization of this kind of malware as an insecure endpoint, the PC which is the endpoint of the conversation with the bank isn't actually under the control of the person who's using it. more

Ten Stopgap Tips for Privacy and Security Risk Management in a Pandemic

As businesses adjust to the "new normal" in the ongoing COVID-19 pandemic, it is important to quickly take stock of where your organization stands on privacy and security risk. Even in these unusual circumstances, organizations of all sizes and sophistication continue to be expected to act with reasonable care and comply with their public commitments and regulatory obligations. Enterprises may be finding different or better ways to operate, collaborate, and service customers. more

WikiLeaks and Stuxnet - Smart Grid Wakeup Calls

The past couple of weeks have been pretty seminal for anyone concerned about the state of Internet security and the bigger picture as to how much we could - do - and should - trust the Web. These two strange words - WikiLeaks and Stuxnet - have suddenly entered our lexicon and there is a lot to be concerned about in the world of smart grid. more

Over 360 Security Experts Around the World From Group to Combat COVID-19 Hackers, Protect Hospitals

An international group of more than 360 cyber threat intelligence researchers from over 40 countries have joined forces to help the medical sector amid the COVID-19 crisis. more

A Case of Mistaken Identity

As far as facebook is concerned, your email is your identification. This is true for other social networks like linkedin, and is slowly catching on to many other Web 2.0 services. It actually makes a lot of sense that your unique identifier (your "ID") would be your email -- it's unique by definition, it's easy to remember and most services need the email information anyway... So if email is destined to become the equivalent of your social security number or identification number (depending on which country you live in) how do we proof check that the email address we typed does not contain any typos? more

A Cynic’s View of 2015 Security Predictions - Part 2

Every year those in the security industry are bombarded with various cyber security predictions. There's the good, the bad and the ugly. Some predictions are fairly ground breaking, while others are just recycled from previous years -- that's allowed of course if the threats still stand. In part one of my predictions I looked at the malware threats, so let's take a look at big data and the cloud for part two. more

Why Domain Name Security Matters Most?

In my recent CircleID post, DNS, Domain Names, and Certificates: The Missing Links in Most Cybersecurity Risk Postures, I highlighted the importance of applying multiple layers of defense to secure these business-critical assets. Last Friday, Brian Krebs, the world-renowned cybersecurity journalist, reiterated the criticality of domain name security because the domain name "e-hawk.net" was stolen from the rightful owner using social engineering tactics targeting its domain name registrar. more

Email More Secure Today Than Two Years Ago, Research Suggests

Google in partnership with the University of Michigan and the University of Illinois, has published the results of a multi-year study that measured how email security has evolved since 2013. Although Gmail was the foundation of the research, insights from the study are believed to be applicable to email more broadly. more

Schneier and Kerr on Encryption Workarounds

Bruce Schneier is a famous cryptography expert and Orin Kerr a famous cyberlaw professor. Together they've published a law journal article on Encryption Workarounds. It's intended for lawyers so it's quite accessible to non-technical readers. The article starts with a summary of how encryption works, and then goes through six workarounds to get the text of an encrypted message. more

Taking a Closer Look at the Recent DDoS Attacks and What it Means for the DNS

The recent attacks on the DNS infrastructure operated by Dyn in October 2016 have generated a lot of comment in recent days. Indeed, it's not often that the DNS itself has been prominent in the mainstream of news commentary, and in some ways, this DNS DDOS prominence is for all the wrong reasons! I'd like to speculate a bit on what this attack means for the DNS and what we could do to mitigate the recurrence of such attacks. more

Achieving a Cyber-Reliant Infrastructure

Don't worry about the bad guys turning out the lights. Worry about everything they're stealing while the lights are still on. The theft of intellectual property ranging from Hollywood films to defense secrets is underway by cyber-criminals of various stripes. Maintaining control over intellectual property may be the single most important challenge to American economic security. Implementing a cyber-reliant infrastructure is a national challenge which crosses the traditional boundaries between economic sectors and between public and private domains. more

Zoom Security: The Good, the Bad, and the Business Model

Zoom - one of the hottest companies on the planet right now, as businesses, schools, and individuals switch to various forms of teleconferencing due to the pandemic - has come in for much criticism due to assorted security and privacy flaws. Some of the problems are real but easily fixable, some are due to a mismatch between what Zoom was intended for and how it's being used now - and some are worrisome. more

Leading a Horse to Water

It is one thing to bring broadband internet to the masses, but how do we make them drink from the fountain of knowledge? One of the challenges, of course, is that the industry has not yet sold turn-key applications that capture the imaginations of the unconnected. Surprising as it seems, email, Facebook, file swapping and web surfing have not yet attracted 100% of the population. Are there some applications that might lend themselves to a toll-free model in order to reach the rest of the market? more

Better “Always-On” DDoS Mitigation

Distributed Denial of Services (DDoS) attacks have been the frustration of information technology professionals for many years. When asked, most tell you they wish their internet service providers (ISPs) would simply provide them "clean pipes" all the time and take care of DDoS attacks upstream before they ever get to them. Unfortunately, the resources (equipment and personnel) necessary to clean Internet connections all the time are very expensive and come with several downsides. more

Why Is the Client-Side Scanning a Concern for Encryption?

As today is the Global Encryption Day, I decided to make my first post here on this topic. About two months ago, Apple caused a controversy by announcing the adoption of a measure to combat the spread of Child Sexual Abuse Materials (CSAM). The controversy was so huge that, a month after its announcement, Apple decided to postpone its plans for the new features to have more time to gather information from the various stakeholders and implement improvements before releasing the measures originally announced. more
