 ## 3.6: Interfering with `/dev/random` and `/dev/urandom`
 
+> There is now a blog post explaining this module in a lot more detail. Check it out [here](https://xcellerator.github.io/posts/linux_rootkits_04/)!
+
 Both `/dev/random` and `/dev/urandom` are character devices defined in [`drivers/char/random.c`](https://github.com/torvalds/linux/blob/master/drivers/char/random.c). In particular, we care about the `random_fops` and `urandom_fops` structs which tell us which functions are to be called whenever a process tries to read/write/seek/etc the `random` and `urandom` "files".
