This week in 'Securing AI: A Learning Journey' I got hands on with the awesome #spikee tool.
I also broke down the differences between prompt injection and jailbreaking attacks in the world of LLM cybersecurity.

🚀My biggest AI watershed moment since getting ChatGPT to write a poem in Jamaican dialect.
I’ll be diving deeper into the security side of all this in my new blog 'Securing AI: A Learning Journey'
Join the ride! 🧵👇 #AI #VibeCoding #MCP #LLMs

Imagine the feeling of a long-forgotten canary token triggering in one of your client's estates, which leads you down a path to catch and remove a sophisticated red team...
No need to imagine, as @umairq_ has written up a blog:

Tool Release!
We've been having a lot of fun recently bypassing swathes of security controls using alternative web technologies to smuggle payloads right past mail security products. We've open-sourced the tool that we've been using to leverage WASM:

🚨 Tool Release 🚨
We've just open-sourced our #automation scripts for setting up #vulnerable #Azure environments to practice #cloud red teaming. It's basically free to run and has hints to help you along your journey if needed 💪

Great to see @Maxicorbs, at @UKCyberWeek presenting insights about #cloud #redteaming and security concerns that are being introduced & how red teamers and threat actors are leveraging them to great effect!

ALT Great to see Max Corbridge at UK Cyber Week, presenting insights about #cloud #redteaming and security concerns that are being introduced by transitioning to the cloud, as well as how red teamers and threat actors are leveraging them to great effect! For more insights and how to mitigate these risks chat to Max and his team! #azure, #aws #gcp #security #cybersecurity #risk
I did another thing
Ending the year with a CVE from our Head of Adversarial Simulation @CorbridgeMax. Unauthenticated users are served the default Superuser account name and if the default password has been changed in IBM backup products, a single point of failure for backups labs.jumpsec.com/advisory-cv…

The vast amount of data that builds up during a #purpleteam engagement can quickly become overwhelming if not managed properly. Check out our experience of using the #opensource framework VECTR to solve this problem!

We warned Microsoft back in June about the risk of external tenant interaction being used for initial access, I’m honestly expecting the prevalence of this to sky rocket in coming months. That doesn’t even take into account the IDOR they chose not to fix.

Did an investigation regarding DarkGate delivered by Teams together with my fantastic colleague Jakob Nordenlund at @Truesec.
A lot of good IoC for all defenders!

What a career 🤯#GOAT in my eyes
Seems like everyone’s been doubting us, except us. We know how to work through things together and I’m so proud of my team for the recent improvements. HCS Fort Worth CHAMPS #Greenwall

Having the external collab setting as default (allowing cross org comms) has allowed us use that technique during red teams on several occasions. It also led to @CorbridgeMax and I finding this:

Not limiting external collab is a real, impactful gap.
Microsoft has identified highly targeted social engineering attacks by the threat actor Midnight Blizzard (previously NOBELIUM) using credential theft phishing lures sent as Microsoft Teams chats. Get detailed analysis, IOCs, and recommendations: msft.it/60199EEkv

Full disclosure - this was published yesterday by one of my team mates at @cyvisory
Mr @pfiatde :
xitter.cf/pfiatde/status/1679146…
Microsofts rebranding of Azure AD to Entra ID allows attackers to craft a nice fullchain attack.
There were a lot good phishing domains not claimed, seems like Microsoft did not care about this.
Made a PoC for @cyvisory. Details below:🧵👇
More great coverage of mine and @tde_sec’s research 💪

Its nice to see some tooling off the back of some of our prior research. This demonstrates the impact of allowing external Teams collaboration.
