2022-06-08 My interests in electronics and security together: trying some hardware hacking
One of the subject areas I'm interested in at work is hardware security and hardware hacking. After doing things with rfid earlier I'm now looking at low-level electric interfaces. With the earlier hardware challenges in CTF contests in HackTheBox Cyber Apocalypse CTF 2022 - Intergalactic Chase and The HackTheBox & CryptoHack Cyber Apocalypse 2021 I got interested in logic analyzers. Those sounded expensive (but I never actually checked). And then I read this bit: I recently got this 8ch cheap USB-C logic analyzer from AliExpress and the price shown is 5.42 US dollar. That's really cheap! For that price I can buy one and not be too dissapointed when it blows up or fails to give me the joy I hope. So, ordered: one 8 channel logic analyzer and a set of test leads so I can actually clip this to a circuit. The price for me for the logic analyzer circuit is EUR 6.78 including delivery and taxes. For software I learned about PulseView. This hardware has limitations, but for simple decoding of hardware protocols this is a nice start.
