#+TITLE: Spoof Detect

Detect spoofed website by detecting logos from bank and financial entities in
pages with =ssl certificates= that do not match.

The process is pretty simple:
 - scrape gvt websites to get a list of entities (for argentina it's BCRA)
 - get logos, names and url
 - navigate the url, extract the ssl certificate and look for =img= and tags
   with =id= or =class= logo (needs more heuristics) to make a db of logos
 - screenshot the page and slice it into tiles generating YOLO annotations for
   the detected logos
 - augment data using the logos database and the logoless tiles as background images
 - train yolov5s
 - feed everything to a web extension that will detect the logos in any page
   and show a warning if the =SSL certificate= mismatches the collected one.
