@Jason I’m all in

[Humi @byteHumi]

lmao I can't stop laughing

claude-code has a "Frustrated User Detection"

There's a regex that detects when you're angry
( fully hard coded btw)

When triggered, it changes Claude's behavior/UI state.

Claude literally knows when you're cussing at it.

@logangraham This is awesome

@altcap @TrumpAccounts @dkhos @InvestAmerica24 Why this over a 529? Genuinely curious from a big finance brain like yours.

"Offense and defense aren't peers. Defense is offense's child." - @JohnLaTwC

We built an LLM-powered AMSI provider and paired it against a red team agent. Then, @0xdab0 wrote a blog about it: https://t.co/TTehwMdofs

A few observations from the experiment:

>>> To advance, we must generate unique, ground-truth datasets.

>>> Defenses will need to live at the edge.

>>> The real potential lies in the interaction between red and blue.

>>> This is a blueprint for generative adversarial reinforcement learning.

@ItsReallyNick Big fan of https://t.co/wVRWtJugWX

They offer enrichments for IPs, domains, phone numbers, emails, domains, URLs all in one place.

Absolutely killer research by Matt Graeber on the @redcanary blog this week about compromising (and defending) Azure OpenAI resources. https://t.co/BnAvLRPsYC

[Brian Donohue @briancdonohue]

We analyzed @redcanary detection data from the first half of 2024 to produce a Threat Detection Report midyear update focusing on a trend (identities) and a few emergent threats and techniques. Useful insight for everyone from the SOC to the CISO's office: https://t.co/BjWSUET9mT

@Snowden How’s Russia?

.@Scott_Wiener continues to falsely claim narrow opposition to SB 1047. When in reality there is massive public outcry across research, academic, public and private business and finance. Here is a mega roundup of recent announcements that fully debunk the Senator's claims 🧵

@RadPowerBikes @GlenDunlap_ How’s the build quality on your bike? Took mine for its first ride and the rear wheel broke and bent spokes. @RadPowerBikes support was not very helpful and I’m told the replacement parts are out of stock with not eta…

[Jimmy Astle @AstleJimmy]

I was just informed that it’s now out of stock with no eta on a replacement part

[Jimmy Astle @AstleJimmy]

@RadPowerBikes I took my new RadWagon 5 out for its first ride and a spoke broke immediately. 😔 Further inspection revealed more loose and bent spokes. Customer support couldn't expedite a replacement rear wheel. I need assistance ASAP. Thanks!

An important question looms in the infosec conversation about AI: Will generative AI tools better benefit defenders or adversaries?
Lifted from the trends section of our 2024 Threat Detection Report, here’s how we score the fight https://t.co/dJiEVWIRfu

[Jimmy Astle @AstleJimmy]

@jamieantisocial Glad you are enjoying that section. Brian and I spent a good amount of time focusing on the so what here :)

[Brian Donohue @briancdonohue]

Great news, everyone! @redcanary's 2024 Threat Detection Report is officially live! I've read it three times, and it's our best yet. Every section is worth your time, but I'm going to post my personal highlights in the thread. https://t.co/BjWSUET9mT

Can GenAI improve security operations? Our GenAI lead @AstleJimmy examines the foundations of GenAI success and how we at Red Canary use GenAI in our security operations workflows.

This is interesting research that's worth reading. I'd encourage readers to also consider what's NOT here - these groups didn't use LLMs to make new malware or find zero-days. They used them to help research and write scripts. I'm not panicking about this...

[Brian Donohue @briancdonohue]

Amazon has an overwhelming number of interconnected security and identity products for AWS. A handful of us at @redcanary tried to make sense of the madness by writing a visibility and observability guide with collection tips for logging and detection. https://t.co/CkAFJ7msku
