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...

The Age of Integrity

We need to talk about data integrity. Narrowly, the term refers to ensuring that data isn’t tampered with, either in transit or in storage. Manipulating account balances in bank databases, removing entries from criminal records, and murder by removing notations about allergies from medical record...

Thousands of WordPress Websites Infected with Malware

The malware includes four separate backdoors: Creating four backdoors facilitates the attackers having multiple points of re-entry should one be detected and removed. A unique case we haven't seen before. Which introduces another type of attack made possibly by abusing websites that don't monitor...

Full-Face Masks to Frustrate Identification

This is going to be interesting. It's a video of someone trying on a variety of printed full-face masks. They won't fool anyone for long, but will survive casual scrutiny. And they're cheap and easy to swap...
