This is truly the stuff of nightmares, and I'm definitely going to review our CI/CD infrastructure with this in mind. I'm eagerly awaiting learning what the initial attack vector was.

9 times out of 10, through the front door. Some shit in a .doc, .html or .pdf. The Google-China hack started with targetted pdfs

  • If people didn't allow macros in Excel, stayed in read-only mode in Word and only opened sandboxed PDFs (convert to images in sandbox, OCR result, stitch back together), we would see a sharp decline in successful breaches. But that would be boring.

    • I think opening all PDFs in a browser would be good enough™ as browser sandboxes are about as secure as sandboxing gets.

  • How such an attack is even possible? A bug in the LibreOffice, browser, or Evince?

    • Remember how Adobe removed Flash support from Acrobat a couple of years back? Attacks like this are why. Well, and Flash had other issues, too.

      I'm not sure when you started using PDFs (I remember mid-90s when my Dad told me about this cool new document format that would standardize formats across platforms, screen and paper!), but hardly anything is static any more.

    • The nexus of unsafe programming languages and exploit markets, where for the right price you can purchase undisclosed bugs basically ready to use. Modern offensive security is essentially a bit like shopping in Ikea
