Trojans Embedded in .svg Files

Porn sites are hiding code in .svg files:

Unpacking the attack took work because much of the JavaScript in the .svg images was heavily obscured using a custom version of “JSFuck,” a technique that uses only a handful of character types to encode JavaScript into a camouflaged wall of text.

Once decoded, the script causes the browser to download a chain of additional obfuscated JavaScript. The final payload, a known malicious script called Trojan.JS.Likejack, induces the browser to like a specified Facebook post as long as a user has their account open…

LLM Coding Integrity Breach

Here’s an interesting story about a failure being introduced by LLM-written code. Specifically, the LLM was doing some code refactoring, and when it moved a chunk of code from one file to another it changed a “break” to a “continue.” That turned an error logging statement into an infinite loop, which crashed the system.

This is an integrity failure. Specifically, it’s a failure of processing integrity. And while we can think of particular patches that alleviate this exact failure, the larger problem is much harder to solve.

The “Incriminating Video” Scam

A few years ago, scammers invented a new phishing email. They would claim to have hacked your computer, turned your webcam on, and videoed you watching porn or having sex. BuzzFeed has an article talking about a “shockingly realistic” variant, which includes photos of you and your house—more specific information.

The article contains “steps you can take to figure out if it’s a scam,” but omits the first and most fundamental piece of advice: If the hacker had incriminating video about you, they would show you a clip. Just a taste, not the worst bits so you had to worry about how bad it could be, but something. If the hacker doesn’t show you any video, they don’t have any video.
