Not long ago I posted about https://pwn.college. I got hooked with it myself, and I almost got my yellow belt ๐ almost, โcause I still have some of the earlier/easier challenges left ๐ Iโll tackle them after the holidays ๐๏ธ before looking at the more advanced modules.
Anyhow, babyrop_level15.0 was *hard*, while tcache safe linking challenges were mind-bending. And donโt even get me started on Yan85 ๐
