@0xdf_ And don’t feel more exhausted about that and falling behind with skills?

Because I do and my day looks similar;)

@TJ_Null I’m pretty sure that they changed sth with 4.8 and legitimate work is blocked

@Jhaddix @Jhaddix about what course you talking about?

[Rafael Gacek @BerSec_]

@archonik Weź piszesz o czymś co mi jakieś wspomnienia wzbudza a nie piszesz czego dotyczy 😅 o co chodzi? Będzie taka gra na coś?

[Rafael Gacek @BerSec_]

@Jhaddix Sure it is. Is it part of your hackbot course?

[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

I’m once again here to tell you that *most* bug bounty platforms will or have used your hunting data in AI endeavors.

bug bounty as an enterprise strategy is much lower margin than AI security.

Or they will use it for auto triage. Which then they will conveniently forget those models were trained on hunter data and transition those models to discovery.

Also. Be wary of specific wording / terminology . They may not train a model with the data, but they may take the tools and techniques and use their engineering teams to turn those into automations that the AI will fire and scale.

@Jhaddix @monkehack @Rhynorater @rez0__ Yeah sure ;)
