Looking back on 2022, we enjoyed researching and testing a large variety of technologies and systems on behalf of our clients. Our latest blog post by @as4s4hetic describes one such system and we hope it helps anyone protecting similar systems. sheasecurity.com.au/ibm-info…

We collectively advocate the decriminalization of hacking. Because good-faith research and activism are fundamental rights in promoting the tenets of free and equal societies.
