How we pwned X (Twitter), Vercel, Cursor, Discord, and hundreds of companies through a supply-chain attack

hi, i'm daniel. i'm a 16-year-old high school senior. in my free time, i hack billion dollar companies and build cool stuff.

The core principle behind extracting a signature from a PDF involves identifying and isolating the signature's visual representation, whether it's a digitally embedded signature or a scanned image of a handwritten signature.

Digital signatures

They are embedded within the PDF structure as data objects, often associated with a signature handler that uses Public/Private Key cryptography. These data objects include information about what parts of the document were signed, the signer’s identity, and a cryptographic hash. The extraction involves locating these fields, reading their content, and interpreting the digital certificate and signature metadata. Digital signatures are generally interactive with form field of type/Sig th
