“Burp AT integrates seamlessly with Burp’s existing tooling and functionality, instead of being just another chat interface to an LLM.”
Burp AT vs Juice Shop, Safe Mode on, no hints: 3 unintended RCEs and a critical handlebars CVE (CVSS 9.2).
@ElliottSaysWhat, web app pentester at Leidos, shares what to feed it, how to steer it and what it cost.

How do you test how powerful an AI testing tool is?
@0xTib3rius built his own target: a bespoke vulnerable app, source code never published, with three known, tricky paths to RCE. Then he tried Burp AT.
Burp AT found a fourth within minutes.

New research: CSS: the bomb inside your inbox 💣
Debuting at Black Hat USA today, @garethheyes shows how "safe" CSS in Gmail, Outlook, Fastmail, ProtonMail, Yahoo & AOL Mail becomes a serious attack surface - no JavaScript required.

What CSS alone can do:
💣 Brute-force login tokens from a URL, or run a real-time keylogger inside Outlook's own sanitiser
💣 Mutate "cleaned" CSS into live selectors that hijack clicks & deface UI
💣 Hide instructions from humans but not AI email agents, exfiltrating data

Responsible disclosure works: 2 Fastmail bugs fixed, bounties paid for both.
If you build or secure anything that renders untrusted HTML/CSS, this isn't one to miss.

🚨 New from @PortSwiggerRes's James Kettle @albinowax
At #BlackHatUSA today: can AI invent genuinely new attack techniques, not just find known bugs?
Yes - and it compromised banks, government infrastructure, and an airport along the way.

☠️ AI can do original security research, not just pattern-match known bugs
☠️ It found a genuine 0-day (now CVE-2026-63078)
☠️Its biggest discovery, "Shared-Parser Confusion," only surfaced once a human stepped back in. AI took it 90% of the way; human judgment found the rest

This human-in-the-loop model is exactly what powers Burp AT, our agentic AI for pentesting - and this research is already shaping it.
