When Businesses Go Dark: A DDoS Survey

In February 2012, Neustar surveyed IT professionals across North America to better understand their DDoS experiences. Most were network services managers, senior systems engineers, systems administrators and directors of IT operations. In all, 1,000 people from 26 different industries shared responses about attacks, defenses, ongoing concerns, risks and financial losses. more

Israel’s Entire Voter Registry Exposed, the Massive Data Leak Involves 6.5 Million Voters

Israel's entire voter registry was recently uploaded to a vulnerable voting management app which effectively left the data wide open for days. more

Protecting Yourself from Spear Phishing

One of the big trends this year is spear phishing. These are phish attacks that are frequently (though not always) against high profile users. The purpose of these attacks is to steal sensitive data or get elevation of privilege inside the service by exploiting a software vulnerability within the user's computer that transmits usernames and passwords back to the phisher. more

DNS Security Flaw Secret Leaked Prior to Set Date: Patch DNS as Fast as Possible

In what seems to have started with a blog post by reverse engineer Halvar Flake, and subsequent blog postings from other experts in the know, the details of the recently announced DNS vulnerability was quite likely made public today. The DNS flaw was found earlier this year by security researcher Dan Kaminsky and earlier this month announced publicly along with various tools and patches provided by numerous vendors... more

An Update on Securing BGP from IETF 102

One way or another we've been working on various aspects of securing the Internet's inter-domain routing system for many years. I recall presentations dating back to the late '90's that point vaguely to using some form of a digital signature on BGP updates that would allow a BGP speaker to assure themselves as to the veracity of a route advertisement. more

Beware of Abandoned Domain Names in this Turbulent Time and as the Global Economy Changes

The outbreak of COVID-19 has caused worldwide disruption -- for whole nations and their economies. Unfortunately, there will be some side effects for businesses. A number of brands will disappear from the streets and shelves, as businesses that fail to weather the storm will have to fold. Companies that do survive will likely focus more on their core markets, pulling brands out of higher risk, less profitable markets... more

The Cost of an ISO 27001 Certification

The first question I often get when talking to IT Service providers on ISO 27001 certification is: "How much does it cost to get it?" I like to reply with a question: "how much does it cost when you don't have it?" The answer to the first question is easy, the answer to the second one is more complicated. As a financial I am interested in the business case. If the cost of not having an ISO 27001 certification is higher than the cost of getting and maintaining one, you can actually make a profitable investment by getting certified. more

Zoom Cryptography and Authentication Problems

In my last blog post about Zoom, I noted that the company says "that critics have misunderstood how they do encryption." New research from Citizen Lab show that not only were the critics correct, Zoom's design shows that they're completely ignorant about encryption. When companies roll their own crypto, I expect it to have flaws. I don't expect those flaws to be errors I'd find unacceptable in an introductory undergraduate class, but that's what happened here. more

Critical Data Belongs in the Cloud, Not Under It - Lessons Learned from Irene

"As flood waters from Tropical Storm Irene swamped the Waterbury state office complex, seven employees from the Vermont Agency of Human Services rushed inside to rescue computer servers that are critical for processing welfare checks and keeping track of paroled prisoners living around the state," according to a story by Shay Totten on the 7days blog Blurt. Two of the employees - network administrator Andrew Matt and deputy chief information officer Darin Prail - lost their cars in the parking lot as the river rose but kept on working to assure that our servers were not lost. "We didn't know how much time we had," Matt said, "and our job was to save the servers." more

Cybercrime and “Remote Search”

According to news reports, part of the EU's cybercrime strategy is "remote search" of suspects' computers. I'm not 100% certain what that means, but likely guesses are alarming. The most obvious interpretation is also the most alarming: that some police officer will have the right and the ability to peruse people's computers from his or her desktop. How, precisely, is this to be done? Will Microsoft and Apple – and Ubuntu and Red Hat and all the BSDs and everyone else who ships systems – have to build back doors into all operating systems? more

Understanding the Threat Landscape: Basic Methodologies for Tracking Attack Campaigns

The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more

A Data Dumb Exposes 773 Million Unique Email Addresses, 22 Million Passwords

Close to 773 million unique email addresses and 22 million unique passwords were found to be hosted on cloud service MEGA. more

Canadian Government Quietly Pursuing New ISP Code of Conduct

If approved, the code would technically be voluntary for Canadian ISPs, but the active involvement of government officials suggests that most large providers would feel pressured to participate. The move toward an ISP code of conduct would likely form part of a two-pronged strategy to combat malicious software that can lead to cybercrime, identity theft, and other harms. First, the long-delayed anti-spam legislation features new disclosure requirements for the installation of software along with tough penalties for non-compliance. more

UK registry Nominet has enabled the deployment of domain name system security extensions (DNSSEC) for 9.4 million second level .uk domains. Completing the rollout represents over a year's work and marks an important milestone in making the web a more trusted environment for UK consumers and businesses, says Nominet, which is responsible for running the .uk internet infrastructure. more
