cfp.recon.cx Adventures of My Oven (Pinocchio) with ChipWhisperer 2023You probably wouldn't consider power analysis & fault injection being a required skill set for your oven repair person. But when your oven is actively lying to you and not just broken, a new type of repair is needed beyond just replacing a heating element. This talk starts from a common complaint: h...

RevEng @infosec.pub Sips' @slrpnk.net Anyone able to help me determine the contents of this "pu.jp" file?
Hi, so am doing some research on some free vpns, and in one of them found a random google drive url, that downloads a "pu.pj" file. While the internet says .pj files belong to a nintendo64 emulator, I am not able to use it to open the pj-file. The contents of the pj- file is a 4608 long of ASCII characters. Which i've tried to decode but dont seem to be able to. However, the Linux command "file -C pu.pj" does give a bunch of strings, but it contains a bunch of random stuff, im not sure what to make of it. Anyone able to help me pinpoint this?

RevEng @infosec.pub Sips' @slrpnk.net Interesting findings within a VPN app
cross-posted from: https://slrpnk.net/post/8481443
I am currently investigating and reverse engineering free VPNs for a master thesis, and just came across something I thought I'd share. Not sure if I'll name-drop the VPN that this code is from, but it's not the one mentioned within the hardcoded links... Nor do I encourage visiting any of the links in the screenshot.
I'm sharing this as a warning as to never use free vpns! They are most often the opposite of what they promise to be. (by free I do not mean the free versions of premium services). But either way; be careful about your VPN choice, as they have access to a lot of sensitive data. I'm sure most peeps here know of this already, but next time you hear someone using a free vpn, let them know...
This first image/code was sitting inside a file called NetworkModule, with some hella weird external links.

cloud.binary.ninja Binary Ninja CloudBinary Ninja Cloud is a completely free, online, collaborative reverse engineering suite, which uses Binary Ninja for analysis.
Is binja cloud abandoned? I liked the idea of a shared database, especially for CTF problems but it doesn’t really seem like the cloud option is supported. Apparently it was for ML training data for binja but I haven’t seen any new features related to ML in binja either…

Improvements!
- Debugger:LLDB. Upgraded SWIG-generated Java (plus docs) to LLVM/lldb 16.x. (GP-3442, Issue #5359) Decompiler. Added an option to the Decompiler, controlling the maximum size of jumptable that can be recovered. (GP-3266)
- Decompiler. Improved Decompiler function call-override to consider calling convention when differentiating function signatures. (GP-3268, Issue #5335)
- Decompiler. The Decompiler now respects tool options for shortening template strings within symbol names. (GP-3369)
- Importer:ELF. Added Max Zero-Segment Discard Size import option to ELF Loader. Value was previously hard-coded to 255 bytes. (GP-3428, Issue #5273)
- Importer:Mach-O. Restored Mach-O indirect symbol creation when binding information is not present, such as when importing a DYLIB extracted from a dyld_shared_cache. (GP-3526)
- Languages. Added windows__stdcall calling convention as an alias to the default calling convention for aarch64 and x86-64. (GP-3472)
- Scripting. Improved the Rec
