The top U.S. cyber agency isn't doing as much outreach during F5 cyberattack It's unclear if the lack of communication is due to the government shutdown or earlier workforce cuts.

CISA's stakeholder engagement division hasn't sent updates about the F5 intrusion in the last week, an industry source tells me.

and following RIF notices this month, the division is expected to host a town hall Thursday to discuss those cuts.

I know this stuff isn't surprising anymore but I really can't stress enough how much everybody involved with CISA and cyber tried to keep the field nonpolitical and nonpartisan before this administration.

Trump administration to spend $1 billion on 'offensive' hacking operations | TechCrunch A top Democrat criticized the move to spend a billion on offensive hacking operations as the budget guts a billion from U.S. cyber defense.

NEW: Trump's One Big Beautiful bill earmarked $1,000,000,000 (yep, a billion) over 4 years for "offensive cyber operations" for the Department of Defense.

It's unclear exactly what that means, but could include zero-days, spyware, implants, infrastructure, etc.
