There is a new cybersecurity con coming to Boston this spring, MinuteCon! Boston has a long history of cybersecurity impact going back to the @l0pht.bsky.social days in the 90s but hasn't had a major hackerish oriented con since Source Boston 10 yrs ago. Looking forward to this! www.minutecon.org

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."

In order to collect a bug bounty, a researcher was required to sign an NDA to not discuss the vulnerability. zuernerd.github.io/blog/2026/01...

Barnaby Jack dragged this attack class into the open in 2010 with a live BlackHat demo & coined the term jackpotting. He showed ATMs are just poorly defended computers w/cash attached. 15 yrs later attackers are still proving him right. Vendors/operators keep relearning the same lesson the hard way

I'm heartbroken to share that my friend of 30 yrs, Arthur Phillip Delchi, @delchi.bsky.social, DJ Delchi, has left us. A founding force behind DEF CON’s Hackers with Disabilities, a member of cDc Ninja Strike Force, a L0pht regular who DJed our wildest parties (two of those moments captured below)

30 years ago today, I saw Hackers in theaters with my crew @l0pht.bsky.social Later, I met my wife @debdebdeb.bsky.social on IRC. Then I co-founded a cybersecurity company @veracode.bsky.social with fellow L0pht hacker @dildog.l0pht.com What a journey! Anyone else feeling old? Post your story.

On this Sept 11, we remember. My wife served at Ground Zero as a first responder. Yesterday she rang the radiation bell, a milestone on her road to beating breast cancer. Grief + gratitude, service + strength. Proud of her. #NeverForget #FirstResponder #BreastCancer

Over the last 2 yrs LLMs have vastly improved their ability to write syntactically correct code, but they haven’t improved in ability to write code without vulnerabilities which is steady at 45% coding tasks with vulns.

Hyde Hack to the Future Hackathon going on at Veracode has had some incredible moments. doc’s car paid us a visit and since I’m Weldy McPond I decided to wear my orange down vest to get into my role.

Last time I was in a play, I was Falstaff in "A Midsummer Night’s Dream" (yeah, that’s not a typo. it was 5th grade). Now I’m back as Weldy McPond in @veracode.bsky.social's “Hack to the Future.” From Shakespeare to cyber-chaos—what could go wrong?

The @l0pht.bsky.social got a Battlezone machine in 1995 when it was 15 years old. It was the first FPS arcade game! Now it's pushing 45 and needs repair. It got new resistors and a cleaning. Still work to be done however as it gets to the gameplay screen and no tanks show up including yours!

Its taking longer for teams to fix security flaws found during testing.

Chris Wysopal @weld.bsky.social · 27/02/2025
There is some bad news, however. It takes longer than a year to fix some critical issues in half of organizations. 70% of this type of risk is coming from 3rd party code in the form of OSS libraries/packages. Is it getting more complex to update libraries to new versions?

Is this potential ban because the products have more security vulns than average or the update process is poor or is there a fear of backdoors? Make the reasons clear and hold all vendors to the standard.

BreachRX analyzed the SEC public 8-K filings disclosing cyber incidents. They found a startling lack of transparency which goes against the whole point of requiring public filings. How can investors & people doing business with you have any confidence if this is what they get?
