    This Week in Tech hosted by Leo Laporte, with a panel of 2-4 guests every week, focused on technology news. Leo has been podcasting since before it was called podcasting. Some of you may remember him as the host of The Screen Savers from TechTV, or The Tech Guy radio show.

    Decentered a podcast about the Fediverse with involved developers as guests!

    The Delta Flyers Tom (Robert Duncan McNeill) and Harry (Garrett Wang) talk about working on Voyager, with other Star Trek cast & crew as guests. They’ve actually finished all of Voyager (nice backlog to listen to) and started covering DS9, adding Jadzia (Terry Farrell) and Quark (Armin Shimerman) as co-hosts.

    risky.biz This one’s more niche, a weekly global cybersecurity news review. Patrick Gray (the show runner) and Adam Boileau (regular co-host) are old experts in infosec with a lot of knowledge and a lot of industry contacts who they interview regularly. In the present there’s a lot of overlap with international politics, so getting an understanding of current events from the cybersecurity perspective is pretty interesting. If you are a professional working in IT or a hobbyist with an interest in computer networking or information security you should be listening to this one regularly.

    Oh, it’s not, the difference is that the SVG is an unexpected delivery vector.

    The script on a website might change over time, might be blocked by an extension like uBlock origin that prevents sections of web code from loading in the first place. You can block a website’s JS with an extension that specifically does that, like jshelter. A malicious SVG is static, the malicious code is malicious forever and is embedded in the file. A browser extension can’t selectively block pieces of the file from loading.

    Script blocking extensions prevent web page code from loading, but they don’t prevent the application from executing JS. If you open an SVG, the file is downloaded locally (it’s not web code) and the JS in the file will execute locally, with the same permissions and file system access as the user opening the file.

    YSK: SVG files are a security risk. Be careful where you get them from and how you handle them.

    Basically, an SVG can contain JavaScript. If you open an SVG in an application that can interpret the JS (e.g. a web browser) then the script will execute (just as with a malicious PDF), at which point it could download other files (malware) or perform any other function that the application has access to (creating, editing or deleting files on the hard drive) because you gave it permission to do that by opening the SVG. Effectively opening an SVG in a JS-capable application is the same as allowing a stranger to run arbitrary code on your computer. You might as well go around the Internet wearing a “please hack me” sign.

    Downloading an SVG to your hard drive directly should be relatively safe, and opening it in a graphics program that does not execute JavaScript should have no risk, but viewing random SVGs in a web browser is a real hazard.
