The ISP Column A column on things Internet Other Formats: The Size of Packets October 2024 Geoff Huston We've now been running packet-switched networks for many decades, and these days it's packets and not virtual circuits lie behind most of the world's digital communications service. But some very fundamental questions remain unanswered in this packet-switched world. Perhaps the most basic questions is: "How big should a packet be?" And, surprisingly enough, there is no clear answer!

Unlike some other public repositories, the npm package repository is never really quiet. And, while there has been some decline in malware numbers between 2023 and 2024, this year's numbers don’t seem to continue that downward trend. Still, while RL has detected some interesting npm malware so far this year, none of it warranted a detailed writeup. Then March rolled around, and two very interesting packages were published on npm: ethers-provider2 and ethers-providerz. These were simple downlo

Two malicious packages were discovered on npm (Node package manager) that covertly patch legitimate, locally installed packages to inject a persistent reverse shell backdoor. This way, even if the victim removes the malicious packages, the backdoor remains on their system. The new tactic was discovered by researchers at Reversing Labs, who warned about the risk it entails, even if the packages weren't downloaded in large numbers. "It's not unusual to encounter downloaders on npm; they are may

Appetite for ether ETFs has been tepid since their launch last July, but that could change if some of the regulatory wrinkles holding them back get "resolved," according to Robert Mitchnick, head of digital assets at BlackRock. There's a widely held view that the success of ether ETFs has been "meh" compared to the explosive growth in funds tracking bitcoin, Mitchnick said at the Digital Asset Summit in New York City Thursday. Though he sees that as a "misconception," he acknowledged that the i

Writing your own TCP/IP stack may seem like a daunting task. Indeed, TCP has accumulated many specifications over its lifetime of more than thirty years. The core specification, however, is seemingly compact - the important parts being TCP header parsing, the state machine, congestion control and retransmission timeout computation. The most common layer 2 and layer 3 protocols, Ethernet and IP respectively, pale in comparison to TCP’s complexity. In this blog series, we will implement a minimal
