Want to become an ethical hacker? 🥷 Here's a list of my favourite [mostly practical] resources 📚
They are all free (or have a free option) and there's more high quality material here than anybody realistically has the time to complete ⏳
In the middle of working on some @metasploit modules and @github banned my work account 🫠
Daybreak Blue just stopped working at the same time as all the other models stopped answering *anything* hacking related. When I go to @OpenAI cyber page it says my account is not eligible for individual access and to contact my org (old uni). Support are refusing any refund 💀
I'm seeing some other people post about Daybreak issues (maybe due to PHP RCE) so hoping my account error is just coincidence! 🤞

Episode 17 of Hacktics & Telemetry is live: Zimbra Zero-Days, AI Torture, and Catching Malmons (ft. @LambdaMamba)! Get it here: youtube.com/watch?v=iWpykLFI…
Found a CSRF in User Registration & Membership that lets an attacker approve or deny users through a logged-in admin. $17 🤑

How @joaxcar must feel after discovering a CVSS 10.0 bug in Gitlab but it's overshadowed because PHP decides to drop a 14 yo RCE

To teach a lesson,
After Wiz rushed to buy php2shell domain and use its marketing machine to steal the spotlight, I spotted "phpbleed" in a recent Calif tweet and bought phpbleed.com before wiz could pull the same stunt again.
A big budget can buy a domain. It shouldn't buy someone else's research credit.
If you have contacts at CISA or in the press, do the right thing: make sure the researchers who actually did the work get the recognition they deserve.
Hack the planet. Credit the researchers.
Let’s set the record straight: @lcfr_hax was the first to discover php2shell and develop a working exploit. See his August 5 tweet: xitter.cf/lcfr_hax/status/208503…
His work convinced the PHP Foundation to invest in fixing this entire bug class. He then worked around the clock to review, test, and retest the patches.
Last Frappe post: GET CSRF in the bulk update endpoint, chained to RCE against a Website Manager.

Three new @metasploit exploit modules in the queue for several of the recent Cisco Secure Email Gateway vulns. Last weeks file write in AMP (CVE-2026-76519, on KEV), and two separate SQLi's (CVE-2026-76461, on KEV, and CVE-2026-76443) from last month: github.com/rapid7/metasploit…
Part 3/4 pwning Frappe / ERPNext: unpublishing a Frappe Web Form leaves its submission RPC live. A guest who knows the form name creates the backing document, permissions ignored 😬

Part 2/4 pwning Frappe / ERPNext: a guest-triggered email embeds a file by path, the inline-image scanner reads it off disk, and /etc/passwd comes back 🙏
