I really believe that if your infrastructure can’t survive a user clicking a link, you are doomed. I’m the director of cybersecurity at NSA and you can definitely craft an email link I will click…

One of my biggest pet peeves within infosec is how people still refer to "knowing your network". In the era of cloud networks that really aren't yours, SaaS networks that definitely aren't yours... let's rebrand to "knowing your environment" which consists of: endpoints, SaaS, servers, and cloud.

I’m clearly a fan of them getting caught because it gives us a glimpse of some of the only nation state macOS targeting with a pretty high cadence recently (and we’ll I’m a defender so suck it hackers). Are other macOS attacks undetected or is πŸ‡°πŸ‡΅ the only targeting entity?

πŸ‡°πŸ‡΅ operators seem brutally effective at getting to target environments directly (crypto scams, backdoored apps) and now more supply chain targeting (3CX, and JumpCloud)… do they not care about stealth if they accomplish their goals? πŸ€”

The evolution through 8 versions and adding support for GCP & Azure is my favorite part of this series.

Inclusion of YARA based malware detection is great but would have loved CloudTrail and equivalent log based detection that defenders could use 🀞

I would test this and see what detection opportunities exist with the Jira/Confluence audit logs but I already know there is not enough info logged to find token theft. Defenders have to rely on EDR logging for the token theft and hope users only access from work machines πŸ‘Ž

Seems like the answer to this was to some extent: yes, 0-day was used.

New *OS releases (see https://support.apple.com/en-us/HT213814) from today include a mention of the Kaspersky team for CVE-2023-32434 so it seems like there was some level of 0-day with the Triangulation attack
