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.

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.

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