Cybersecurity and privacy technology offer better solutions. Courts and lawmakers should do better!

Tl/dr: more control and less freedom online, as the justices decide to prioritize potential harms in uphold a ban on TikTok and age verification for accessing pornography.

Brown to confer honorary degrees on seven distinguished leaders at Commencement 2025 The University will bestow honorary degrees on a diverse group of community leaders, artists, writers, performers and scholars during its Commencement exercises on Sunday, May 25.

It’s a special honor to be among those receiving honorary degrees from Brown. It’s a place that welcomed me and shaped me and challenged me and liberated me, and made possible everything that came after. I’m looking forward to celebrating this weekend with friends.

Signal Gate: The Criminal Law Precedents That Are Most Relevant A range of federal laws, including the Espionage Act and laws against the destruction of government records, could apply in Signal Gate.

With renewed relevance, this explainer I wrote last month:

Signal Gate: The Criminal Law Precedents That Are Most Relevant

The key legal issues are:

--> 18 U.S.C. 793(f)(1) of the Espionage Act - gross negligence
--> Destruction of government records

CISA reverses course, extends MITRE CVE contract While the last-minute extension averts an immediate lapse in support, rival organizations are being stood up to supplant the global vulnerability system.

In a last-minute switch, the #CISA said it will continue funding a contract for #MITRE to manage the CVE program and other vulnerability databases. via @derekbjohnson.bsky.social cyberscoop.com/cisa-reverse...

Historical tidbit: the reason it was called D-Day is so the Germans wouldn't know what DAY the attack was coming, which was sensitive even though they didn't know where the attack was coming.

Leaving the nuclear codes in a Starbucks would be reckless even if a journalist noticed and politely gave them back to you without publishing them.

Trump’s Presidential Records Act Violations: Short- and Long-Term Solutions What are available mechanisms for accountability against a president who violates these rules?

Remember when Trump tore up documents and flushed them down the WH toilet in his first term? Here's a good analysis in @lawfare.bsky.social of the laws that were broken then. www.lawfaremedia.org/article/trum...

There are also criminal penalties for intentionally making US government records disappear. 18 U.S.C. Β§ 641 (β€œWhoever . . . disposes of any record . . . of the United States . . . [s]hall be fined under this title or imprisoned not more than ten years, or both.”)

28.03.2025 14:19 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

The law specifically provides that using private messaging services without copying official accounts for records preservation subjects WH staff to disciplinary action. 44 U.S.C. Β§ 2209.

Fun fact: Presidential Records Act provides that WH staff may not use a "non-official electronic messaging account" without copying an official account so records may be preserved. 44 U.S.C. Β§ 2209.

Just so we're all clear on the law: it is a crime punishable by up to 10 years in prison to allow "information relating to the national defense through gross negligence" to be delivered to people not allowed to received it. Espionage Act, 18 U.S.C. Β§ 793(f).

A high-level conversation about whether to conduct military operations, and following them in real time, is literally what the Situation Room is for. Saying they were unclassified insults our intelligence. www.businessinsider.com/trump-admini...

Don't have classified conversations on commercial platforms - and yes, discussing military strikes before they happen is classified, I tell @businessinsider.com

Holy cow❗

People apparently _returned_ from El Salvador for mistaken identity etc. in Alien Enemies Act deportations.

This new development appears to show that the Trump administration's claim that they know all detainees sent to El Salvador prison were properly vetted may be dangerously false.⬇️

This will be a test of the new, close relationships tech has been building with Trump.

If tech calls Congress’ bluff and Trump so much as lifts a finger, lawmakers’ only play will be to roll over or to push the big red button that blows up the internet, even as they admit that’s not the goal.

Machine Surveillance is Being Super-Charged by Large AI Models | ACLU Limits and guardrails are vital to protect our privacy and liberty β€” as well as our sanity β€” against omnipresent AI surveillance.

Large language model technology is super-charging video analytics. Unless we enact guardrails, we can expect that nearly every rule, regulation, law, and employer dictate that can be enforced through the visual monitoring of human beings will be subject to unblinking AI cameras ready to report us.

Perhaps the talk of offensive cyber is just that - talk - serving as a smokescreen for ignoring the far more important task of making public and private computer system secure.
