Revisiting How Registrants Can Reduce the Threat of Domain Hijacking

Recent events have shown the threat of domain hijacking is very real; however, it is also largely preventable. As Verisign previously noted, there are many security controls that registrants can utilize to help strengthen their security posture. Verisign would like to reiterate this advice within the context of the recent domain hijacking reports. Domains are an important element of internet infrastructure; their functionality and security rely upon many factors such as their delegated name servers. more

Starting a New Conversation on Cybersecurity

The cybersecurity debate can be highly confusing at times. There is perhaps an analogy to be made between "Cybersecurity" and "The Economy". We all want to fix the economy but making progress is not an easy task. As soon as you are beyond that statement you notice that there is a lot of nuance. Issues like trust, influence, actors, and affectivity all come to play when you want to fix the Economy. The cybersecurity discourse has similar features. more

More Than 500 Schools in the U.S. Hit by Ransomware in 2019, Says Report

A recent report published by the cybersecurity firm Armor says ransomware infections have hit over 500 US schools in 2019 to date. Armor warns the rate of attack seems to be picking up with 15 new ransomware victims in the last two weeks, all of them educational institutions. more

Verisign Outreach Program Remediates Billions of Name Collision Queries

A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. more

Prediction Methods for Crime

There's a new sheriff in town and he's riding the horse of "predictive policing". Back in July the Santa Cruz Police Department began deploying police officers to places where crime is likely to occur in the future -- making use of new predictive modeling programs that are designed to provide daily forecasts of crime hotspots -- thereby allowing the Department to preempt more serious crimes before they occurred. In essence, this is another physical-world application of machine learning and clustering technologies -- applied to preempting a criminal problem. In the cyber-world we've been applying these techniques for a number of years with great success. more

Cisco Issues Hight Alert on IPv6 Vulnerability, Says It Affects Both Cisco and Other Products

Cisco today released a high-level alert warning about a vulnerability in IPv6 packet processing functions of multiple Cisco products that could allow an unauthenticated, remote attacker to cause an affected device to stop processing IPv6 traffic, leading to a denial of service (DoS) condition on the device. more

Florida Cities Are Paying Hundreds of Thousands of Dollars in Ransom to Get Their Data Back

Lake City became the second Florida city to pay a substantial ransomware demand to hackers in less than a week. more

Federal Cybersecurity Best Practices: FISMA Continuous Monitoring

Studies have found only limited, insufficient agency adherence with FISMA's (Federal Information Security Management Act) continuous monitoring mandates. One survey found almost half of federal IT professionals were unaware of continuous monitoring requirements. A recent GAO report found that two-thirds of agencies "did not adequately monitor networks" to protect them "from intentional or unintentional harm." more

5G Security Transparency

There is considerable rhetoric propagated today about 5G security. Some of the more blatant assertions border on xenophobia with vague assertions that the 5G vendors from some countries cannot be trusted and wholesale government banning is required. Existing treaty obligations are being summarily abrogated in favour of bilateral trade bullying. These are practices that the late President George H.W. Bush sought to eliminate a quarter century ago through intergovernmental organization initiatives... more

The Path Toward Increasing the Security of DNSSEC with Elliptic Curve Cryptography

How do we make DNSSEC even more secure through the use of elliptic curve cryptography? What are the advantages of algorithms based on elliptic curves? And what steps need to happen to make this a reality? What challenges lie in the way? Over the past few months we've been discussing these questions within the community of people implementing DNSSEC, with an aim of increasing both the security and performance of DNSSEC. more

Researchers Expose Privacy Risks in Apple and Starlink’s Geo-Location Data, Uncovering Military and Civilian Tracking

Researchers from the University of Maryland have revealed significant privacy and security concerns related to the way Apple and Starlink geo-locate devices. Their study found that Apple's Wi-Fi Positioning System (WPS) collects and publicly shares precise locations of Wi-Fi access points. more

Notorious Hacker Group XENOTIME Expands Its Targeting Beyond Oil and Gas to Electric Utility Sector

XENOTIME, the notorious group behind what is regarded as the most dangerous malware targetting industrial control systems has expanded its targeting beyond oil and gas to the electric utility sector. more

Flame On!

Here we go again; another instance of really sophisticated spyware has been reported, a system that is "so complex and sophisticated that it's probably an advanced cyber-weapon unleashed by a wealthy country to wage a protracted espionage campaign on Iran". I won't get into the debate about whether or not it's really more impressive than Stuxnet, whether or not it's groundbreaking, or whether or not Israel launched it; let it suffice to say that there are dissenting views. I'm more interested in the implications. more

Not Quite Two Factor, or Is Your Phone Number Really Something You Have?

A recent article in the New York Times Dealbook column reported on phone number hijacking, in which a bad guy fraudulently takes over someone's mobile phone number and used it to reset credentials and drain the victim's account. It happens a lot, even to the chief technologist of the FTC. This reminds us that security is hard, and understanding two-factor authentication is harder than it seems. more

Report on Smart Grid Cyber Security

A recent report from Pike Research, "Smart Grid Cyber Security" has found if smart grids can realize their full potential, consumers, utilities, nations, and even the earth itself will benefit. As with nearly any new technology, the industry focus has been on getting smart grids up and running, often with little consideration for cyber security issues. more
