Reading disassembly listings for long periods is tiring. I love debuggers because they allow you to quickly test ideas and cut corners while reversing a target. I made good reversing progress with static analysis, but dynamic analysis with a debugger would make the job much easier. That post is available at Apple EFI firmware passwords and the SCBO myth.ДЄll the interesting computing action happened at the EFI execution level.

There was an old rumor that these files were able to unlock firmware password locked Macs (and even a sketchy video about a universal SCBO able to unlock any Mac). In 2016 I reversed AppleвЂ™s EFI firmware password reset scheme using SCBO files. Crafting an EFI Emulator and Interactive Debugger Maybe this could lead to further improvements and make LLDB more reverse engineer friendly. Hopefully it will help others exploring the LLDB codebase, which seems unfriendly because of the lack of really good documentation into its architecture. Instead of just posting a patch, this post is a journey into LLDB internals and how I implemented this feature. Last week I finally got fed up enough to dive into the LLDB C++ codebase and finally try to implement this feature. It has been a serious blocker for me against some targets and a source of immense frustration because it should be a basic debugger feature. While hardware breakpoints might not be needed to debug applications within Xcode, they are essential to any serious reverse engineer dealing with arbitrary untrusted targets such as malware, packers, obfuscators, and DRM. I also hate the lack of a gdbinit style output but Deroko started that project and I improved it with lldbinit.Д«esides its horrible long command line syntax which is so unpopular that gdb-compatible commands were introduced, my biggest problem with it has been the lack of x86 hardware breakpoint support. So we are all essentially stuck with LLDB, warts and all. AppleвЂ™s old gdb fork doesnвЂ™t work anymore and the GNU gdb version is better these days but still quite meh (in the past it couldnвЂ™t deal with fat binary targets and I still think this holds true). These days the de facto debugger in macOS is LLDB. Last time I did something serious in Perl was twenty years ago or so! Why I Left Twitter

Besides being under the radar for more than a decade, it was kind of exotic malware because most of its code was written in Perl. It was first reported by MalwareBytes and then a new variant was analysed by Patrick Wardle.

While sorting out my Mac malware collection I found out that I had an unreleased (no known public references) FruitFly/Quimitchin dropper script lost in my archives.ДЇruitFly made big headlines two years ago and its author has been arrested. My position didnвЂ™t change and given that there is an upcoming presentation about this malware by Thomas Reed at Objective By The Sea itвЂ™s time to re-release this. When paranoia and envy are dominant then everything can be a potential media drama in peopleвЂ™s mind. Personally I donвЂ™t think there is any special drama here other than unreleased technical details about a malware that is dead and its author busted long time ago. It was written over the weekend on my own equipment and was all about information I had way before I joined Apple. This post was originally written back in May 2019 but was removed because of вЂњpressureвЂќ from my employer at the time, Apple.

I would always have a local copy and if GitHub bans me the impact is meaningless - they are just an intermediary and both ends are controlled by me.

GitHub allows unlimited private repositories to free users, and the data to store there isnвЂ™t critical.

I could use GitHub to store the data that I need to edit between devices, and GitHub actions to automate the build process. Last weekend the right idea popped in my mind (I think I was reading something about the topic). For a while I thought about developing a mobile or web application to achieve this but was too lazy for that.

I am definitely not a cloud fan so using it to sync between devices was out of question (people do it with Evernote, etc). One of the main obstacles to build the site was that I needed to add/edit information from my desktop and tablet. I rather do all the work myself than giving up control to a third-party that can lock me down for any reason (Twitter for example).

There must be already plenty of sites to solve this but none satisfies my main requisite: to be under my full control. For quite some time I have wanted to build a site where I could share links to the stuff I read online.
