This is a pretty big shift in US cyber policy. The White House is setting up a program that would let private cybersecurity companies conduct gov-authorized operations against foreign cybercriminal groups, inc surveillance & disruption of their infrastructure www.whitehouse.gov/presidential...

Device vendors, we need a technical fix: use short-lived, rotating device IDs so signals can’t be reliably linked to the same person or vehicle over time.

Unsupported connected devices are becoming a global security risk, but public policy has not kept pace. At BSides LV, Paul Roberts and Silas Cutler will discuss emerging state legislation requiring clear end-of-life disclosures, minimum support transparency, and responsible vendor exit plans.

Polymarket lost ~$3M and their smart contracts worked perfectly. A compromised frontend vendor injected malicious JS client-side. The breach lived in the browser — the layer nobody monitors. Audit what runs, not just what you wrote. www.cybersecurity-insiders.com/software-sup...

Who should get charged with a CFAA violation for the AI agent breach of Hugging Face? The people who built the model or those that operated it unsafely? Someone else?

Replying to @bsky.realhackhistory.org

A third #FOIA release from the #FBI for records on broadcast signal #hacker Captain Midnight and this time it is a recording of a radio interview with the man himself on Portland's KXL radio station at midday. 1986 - I'm unsure of the exact date but it was before he surrendered himself to the feds.

28 years ago today, 7 members of the hacking group L0pht Heavy Industries told the U.S. Senate they could "shut down the internet in 30 minutes."

Couldn’t agree more with @weld.bsky.social about @windowsnyder.bsky.social for @darkreading.bsky.social being “one of the most important security leaders of the past two decades," for her ability to achieve systemic change. Great #Darkreading20 special coverage.

My wife @debdebdeb.bsky.social and I are heartbroken to share the sad news that our old friend @jasonsnitker.bsky.social AKA Parmaster, has passed away.

His story in “Underground” includes the Citibank investigation that helped trigger that pursuit, as well as his time in custody at Rikers Island where he somehow found himself playing Dungeons & Dragons.

Par’s life reflected both the intensity of the early hacking world and the very real consequences that came with it. He was part of a generation exploring the edges of a new technological landscape before most people even knew it existed.

Par was one of the sharpest & most elusive minds of the early underground hacking scene. As chronicled in “Underground,” he spent years navigating the emerging digital frontier, connecting with hackers internationally & staying ahead of US Secret Service during a long investigation in the early 90s
