This article, covers a recent tweet that displayed a vulnerability where a specific SSID name could permanently disable an iPhone's wifi functions. Luckily for user, @vm_call, a user in the replies found a way to fix the wifi. The article covers the process by which the SSID is processed and what the actual issue that causes the crash is. It seems a bit weird to write a blog post about a blog post, but this topic was incredibly interesting and the original tweet and the conversation around it was fun to follow. As for the potential for exploitation for this vulnerability, it isn't something that could be used in it's current state. The target can see the name of the SSID they are connecting to, so they would know that they were connecting to a potentially dangerous network.
PGPy is a library for python that enables the creation, storage, and encryption/decryption of PGP keys and files in python. Recently, in a small project to reacquaint myself with python, I used PGPy for key generation and encryption and decryption. That project can be found in my github at https://github.com/lpowell . The goal of the project was to use command-line switches to control the program, and to provide basic encryption and decryption capabilities, along with rot13 and base64 encoding. First, to load in a key use key, _ = pgpy.PGPKey.from_file(keyfilename) . This loads the key from either a binary or ASCII armored file. You can swap out .from_file for .from_blob , if you plan on using a key stored in a string or bytes object rather than a file. In my example code, I pull the key from a file, as I found it to be the simpler method. Next, you'll need to open a file or create a string or bytes object that contains the message you wish to encrypt. We'll call this file
