Recently I came across a fantastic new paper by a group of NYU and Cornell researchers entitled “How to think about end-to-end encryption and AI.” I’m extremely grateful to see this paper, because while I don’t agree with every one of its conclusions, it’s a good first stab at an incredibly important set of questions. I was particularly happy to see people thinking about this topic, since it’s been on my mind in a half-formed state this past few months.

Malicious exploitation of LNK files, commonly known as Windows shortcuts, is a well-established technique used by threat actors for delivery and persistence. While the value of LNK forensics for cyber threat intelligence (CTI) is fairly well-understood, analysts may overlook less well-known data points and miss valuable insights. In this post, we explore the structure of LNK files using Velociraptor, our open-source digital forensics and incident response (DFIR) tool.

This blog is reserved for more serious things, and ordinarily I wouldn’t spend time on questions like the above. But much as I’d like to spend my time writing about exciting topics, sometimes the world requires a bit of what Brad Delong calls “Intellectual Garbage Pickup,” namely: correcting wrong, or mostly-wrong ideas that spread unchecked across the Internet.

In 2023, Arkansas adopted several laws to restrict the consideration of ESG factors, including Senate Bill (SB) 62, which prohibits public entities from contracting with entities that have been determined to boycott the energy, fossil fuel, firearms, or ammunition industries. It also adopted House Bill (HB) 1253, which requires fiduciaries of state and local pension plans to consider only “pecuniary factors” in their decision-making.

If you’re a normal person — that is, a person who doesn’t obsessively follow the latest cryptography news — you probably didn’t spend a lot of time on last week’s cryptography bombshell. That news comes in the form of a new e-print authored by Yilei Chen, “Quantum Algorithms for Lattice Problems“, which has roiled the cryptography research community.
