Comcast has agreed to be the first home broadband internet provider to handle secure DNS-over-HTTPS queries for Firefox browser users in the US, Mozilla has announced. This means the ISP, which has joined Moz's Trusted Recursive Resolver Program, will perform domain-name-to-IP-address lookups for subscribers using Firefox via encrypted HTTPS channels.

79% of organizations experienced DNS attacks, with the average cost of each attack hovering around $924,000, according to EfficientIP. The 2020 Global DNS Threat Report, conducted in collaboration with IDC, shows that organizations across all industries suffered an average 9.5 attacks this year. In terms of regional damage from DNS attacks, North America leads the way with the average cost of attack at $1,073,000.

A report released Wednesday by network automation and security provider EfficientIP and research firm IDC discusses how DNS is prone to attack and what organizations can do to protect their DNS security. Based on a survey of 900 technology professions across North America, Europe, and Asia Pacific, the "2020 Global DNS Threat Report" found that 79% of organizations were hit by DNS attacks in 2019, down slightly from 82% in 2018.

Infoblox identified the challenges Communication Service Providers face in transitioning to distributed cloud models, as well as the use cases for multi-access edge computing, 5G New Radio, and 5G Next Generation Core networks. "Distributed cloud models such as 5G and multi-access edge computing networks have the potential to drastically change the CSP industry, delivering high-bandwidth, low latency services to network customers," said Dilip Pillaipakam, Vice President and GM of Service Provider Business at Infoblox.

After delays to Chrome version 81 in March, and the scrapping of version 82 a month later, this week sees the early arrival of Chrome 83 with a longer list of new security features than originally planned. First, it's not turned on by default, and might not even be visible under Settings > Privacy and security > Advanced.

Dubbed NXNSAttack, the flaw [PDF] can be abused to pull off a classic amplification attack: you send a small amount of specially crafted data to a DNS server, which responds by sending a lot of data to a victim's server. The recursive server contacts your DNS server for your dot.com for that information.

Israeli cybersecurity researchers have disclosed details about a new flaw impacting DNS protocol that can be exploited to launch amplified, large-scale distributed denial-of-service attacks to takedown targeted websites. Called NXNSAttack, the flaw hinges on the DNS delegation mechanism to force DNS resolvers to generate more DNS queries to authoritative servers of attacker's choice, potentially causing a botnet-scale disruption to online services.
