🤯 The level of sophistication of the XZ attack is very impressive! I tried to make sense of the analysis in a single page (which was quite complicated)! I hope it helps to make sense of the information out there. Please treat the information "as is" while the analysis…
mastodon.social/@q3k@hackerspa… q3k from @DragonSectorCTF has figured out the string/symbol obfuscation in the xz backdoor! there's appears to be a lot more going on then reported in the initial report.
#flareon10 complete, slid into 50th place. I gave it all of my spare time and had a blast the whole way. Highlights for me were FlareSay and kupo, but every challenge was great and satisfying to solve. Thanks to the challenge authors!
Would it be Flare-On if I didn't find myself using the Visual Instruction Meta-optimizer (vim.org) to reconstruct some code? #flareon10
Is the flag in there? Let me in! 12 down. #flareon10
Looks like I made the right choice today. 11 down. #flareon10
Nah, it was actually super chill. 10 down. #flareon10
Just saved $20,000 bucks. 9 down. #flareon10
When you take way too long to get the flag and don't gain any position on the scoreboard. Challenge 7 down. #flareon10
Finding myself by helping computer programs find themselves. 5 down. #flareon10
This is not a drill. They are not messing around this year. Seek shelter. #flareon10 youtube.com/watch?v=CtjxvL…
#flareon9 complete! Challenges 7, 8, and 9 were the sweet spot for chill reversing sessions.
There's far better things to do on a Mac than that. #flareon9 marathon.bungie.org/temp/cmullins/…
Always leave the binary cleaner than you found it. #flareon9
Doing it for the dopamine, this one paid off. #flareon9
For me making analysis "durable" means choosing to put it in structured forms & tech that are consistent, recallable, programmatically query-able & applicable to fresh data. That's why I love using Synapse, Suricata, Sigma and YARA. I want my analysis to live as long as possible.
60% is a passing grade, right? #flareon8

This had to be done: I really like the 2 colour effect of *only* drawing the simple landscape contouring
I played @Bugcrowd's CTF alone and placed 4th out of 325 teams! The challenges were interesting and some of them were quite tough, especially the ones in the web and OSINT categories. Congrats to the winners and thanks for the fun CTF!
Must read from @_CERT_UA on UAC-0133 (APT44/Sandworm) targeting UA critical infrastructure. Extremely notable callout from CERT-UA this was likely in prep for sabotage operations in conjunction with missile strikes on Ukrainian infra in the spring of 2024 cert.gov.ua/article/6278706
I'm currently at 753 hours of listening & watching Spanish out of my goal of 1500 hours and today was the first time I heard anybody say Ay, caramba!
April is Autism Awareness and Acceptance month! Despite being a parent to a teenager on the spectrum, I regularly feel like I don't have any clue about it beyond my own experience, and finding adult people on the spectrum has been really eye opening to that reality.
Every time I worry that I'm actually getting dumber as time goes on, it turns out that I'm just becoming increasingly aware of my own stupidity, and, paradoxically, becoming less dumb! This is confirmed by looking at my past work and realizing that I could do better today.
Thanks @CISAgov for a great competition again this year, and @Google for supporting me as I balance being a member of @marforres and a Googler. Looking forward to participating again next year!
Congratulations to U.S. Marine Corps Staff Sergeant Michael Torres for winning Track B today with a perfect score and making history as the first individual to win the #PresCup more than once. Today kicks of day 1 of the Teams round to see who will escape with the top score.
The volume of understanding baked into APT44 is remarkable. Over 40 merged clusters of activity with operations stretching back a decade. So much insight from the group's wartime operations in Ukraine. A testament to the incredible team here at @Mandiant, past and present.
A nice surprise arrived in the post today. Thanks @greglesnewich! #100DaysofYARA
@ImposeCost saw this better one somewhere here
