Amazing work as always @nao_sec ! For folks hunting for this stuff, I've got some YARA rules + these IoCs published here from my @labscon_io talk on IIS malware: github.com/PwCUK-CTO/labs… In particular, the "Malware_IIS_reGeorg_Unique_Strings" rule will be of use for this stuff!

Following recent reporting by The Citizen Lab and AccessNow on #COLDWASTREL (which we track as White Dev 185), we've put out a blog detailing some further infrastructure of the threat actor, and historic connections to other threat actors: pwc.com/gx/en/issues/c…

Nice research from Check Point. I've blogged about the SessionsIIS backdoor last year, which they mention in their research: pwc.com/gx/en/issues/c… Timely research as well, as I'll also be mentioning these backdoors at @labscon_io next week.

I'm very excited to be speaking at @labscon_io about IIS malware! The whole agenda looks incredible, so I'm honoured to be able to present, and looking forward to seeing everyone who will be attending 😁

For anyone using Binary Ninja and wanting to use Mandiant's ShellcodeHashes IDA plugin-I ported a basic version of the IDA plugin to Binary Ninja: github.com/PwCUK-CTO/Bina… Known limitations - No GUI, no support for searching memory constants - but it works well for most use cases

Analyzing data leaks is a very interesting Intel challenge, especially when you’re dealing with a foreign language 🤓 The I-SOON leak, which contains mostly PNG files of screenshots of documents, is a good example 🔎 Last night, I created a Notebook to automatically process and…

Invaluable advice right here. The more YARA rules I write, the more I prefer having shorter, less complex ones. That doesn't mean you can't have a complicated condition or set of strings, but imo it's a good idea to have one "idea" per rule, where possible

Automating this stuff gives you more time to focus on the novel detection/hunting work 😌 Nice one @fr0gger_ ! 😁

I'm not convinced this isn't just @fr0gger_ typing responses very quickly 😛 This looks like a great resource for if you're starting with YARA! 💊

I've consolidated all my #100DaysofYARA posts from 2023 into one blog post. I've also included the rough breakdown of the posts in case you want to jump to specific sections. bitsofbinary.github.io/yara/2023/01/0… (hopefully all the old links should still work 🤞)

I'm looking forward to seeing what people do for #100DaysofYARA! I'm not planning to do much for it this year - remember that it's good to take a break from infosec stuff at times 👍 But if you're new to YARA, or want to learn new stuff, it's a good chance to give it a go!

Bit off topic for me, but for my threat intel friends, you might enjoy this game! Lots of deductions needed to try and figure out who everyone is - one of my favourite puzzle games!
