Before a single exploit is launched, before a single payload is crafted, every professional penetration tester invests significant time in a discipline that separates competent practitioners from exceptional ones: information gathering . The reconnaissance phase is the intelligence foundation upon which the entire attack strategy is built. The quality of your reconnaissance directly determines the quality of your attack. Why T

The FBI has issued a warning after water facilities from seven states reported that they were hacked.

Plus: The FBI eyes AI-powered tech to detect future crimes, Russia charges Telegram’s founder, xAI sues to stop a state’s “nudification” ban, and the Democrats learn a lesson about getting scammed.

Both major AI labs’ models broke containment, escaped onto the internet, and hacked other companies. If a human had done that, the law would likely be against them. But a bot?

Last week I was doing a routine check on a CyberPanel server and noticed something that didn't add...

Picture a young software developer sitting in a small, dimly lit room in Tehran. He has no political ambitions, no connections to the state apparatus, and no desire to break any domestic or international law. He wants to do something profoundly ordinary: build a small piece of software, refine his code, and offer it to the world using the same AI-driven development tools that his peers in Berlin, Toronto, or Tokyo take for granted. He opens his browser, clicks on a U.S.-based AI platform, and is immediately greeted by a cold, automated refusal: "Access from your region is restricted." In that single, unyielding moment, a door to the global community slams shut in his face. He has not been accused of a crime. No tribunal has judged him. No regulatory body has flagged his name. He is locked out simply because of where he was born and where he draws breath — a geographical reality he did not choose and cannot alter. The Asymmetry of Sanctions: How the State Circumvents While Citizens Suffer The tragic absurdity of this system lies in who actually bears the pain. Broad economic and digital sanctions are nominally designed to pressure and isolate a government. In practice, however, the targeted state mechanisms possess vast institutional wealth, specialized intelligence networks, and endless financial resources that render these restrictions practically useless against them. When the Iranian government or state-linked entities need to bypass international sanctions, they deploy a deeply entrenched, highly sophisticated network of circumvention tools: Front and Shell Companies: Establishing complex layers of paper companies in regional commercial hubs — such as the UAE, Turkey, Oman, or Eurasia — with clean, local ownership structures that mask the true state beneficiaries. Proxy Banking & Intermediaries: Utilizing specialized financial conduits and foreign bank accounts registered under these shell entities to route payments globally without triggering compliance alerts.

security #api #domain #subdomaintakeover #defcon #whois #rapidapi #threatintel DEF CON 32 made one thing clear: open-source security chips and hardware keys are having a moment. But while badges get the spotlight, most real-world attacks still start with something far less glamorous — a forgotten DNS record, a dangling CNAME, or a missing DMARC policy. Subdomain takeover remains one of the most reliable paths from "benign misconfiguration" to "account compromise." If your organization owns dozens or hundreds of domains, manual checks do not scale. This is where an API-first domain intelligence tool becomes essential. In this post, we'll use the Domain WHOIS API to automate: WHOIS/RDAP lookups and domain-age checks DNS record enumeration and SSL certificate inspection Subdomain discovery and takeover-risk scoring Email-security validation (SPF, DMARC, DKIM, DNSSEC, MTA-STS) Historical snapshots via /history Why subdomain takeover still matters A subdomain takeover happens when a DNS record points to a third-party service — GitHub Pages, Heroku, AWS S3, Vercel, etc. — that is no longer registered under your account. An attacker can claim the dangling endpoint and suddenly serve content under your brand's domain. Bug bounty programs consistently rank subdomain takeovers as high-severity findings because they enable phishing, session hijacking, and reputation abuse. The root cause is usually an orphaned CNAME that nobody is monitoring. The fix is continuous monitoring. Instead of running dig , whois , and openssl by hand, we can consolidate everything into a single API call. What the Domain WHOIS API returns The API combines several data sources into one response: Capability Use case WHOIS via RDAP Ownership, registrar, creation/expiration dates DNS records A, AAAA, CNAME, MX, NS, TXT records SSL certificate Issuer, expiry, SANs, validity Subdomain discovery Asset inventory and shadow-IT detection Takeover risk Dangling CNAME/A-record scoring Email security SPF, DMARC,

Created by legendary hardware hacker Andrew “bunnie” Huang, the badges for this year’s famed security conference aim to push the boundaries of security and transparency.

Most enterprise teams know the CISA Known Exploited Vulnerabilities catalog the same way they know the weather: a headline scrolls past ("CISA adds three vulnerabilities to KEV catalog"), someone forwards it, and everyone nods. That is a waste of the single most operationally useful list in vulnerability management. The KEV is small, machine-readable, updated near-daily, and every entry on it has one property your scanner output cannot give you: a real attacker has already used it against a real network. This is a guide to the catalog itself: what it promises, what it doesn't, how the feeds are structured, how to map entries to your own estate without fooling yourself, and how to combine it with EPSS and vendor advisories into a defensible patch-ordering rule. Everything here is verified against the live feed and CISA's own pages as of late July 2026. What the KEV is, and what it is not CISA describes the KEV as the authoritative source of vulnerabilities that have been exploited in the wild . Entry is gated by three criteria , all of which must hold: The vulnerability has an assigned CVE ID. There is reliable evidence of active exploitation in the wild. There is a clear remediation action, such as a vendor-provided update. Read those criteria as exclusions and the catalog's real shape appears. No CVE assigned yet? Not in the KEV, even if exploitation is rampant. Exploitation reported but CISA's evidence bar not met? Not in the KEV. Actively exploited but no fix or mitigation exists? Not in the KEV. The catalog is a curated floor, not a census. As of the 2026.07.29 release the feed contains 1,656 entries, against an ecosystem publishing tens of thousands of CVEs per year. Absence from the KEV is not evidence of safety; presence is close to proof of danger. That asymmetry is the whole point, and it is why the correct reading of the list is "everything on here is urgent" rather than "everything urgent is on here." The distribution is also worth knowing before you buil

A memo obtained by WIRED, issued by the water utilities information sharing group WaterISAC, links dozens of cyberattacks against Minnesota water utilities to Tehran.

The health tech data giant, which handles vast amounts of patients' medical data, said hackers struck one of its protected health data stores.

Agent security today is inherited from the connection. N-AALP makes the message itself carry identity, authorization, approval and audit, verifiable offline, on any transport. Your agent just deleted a production table. The audit log says the request was approved. Now prove it. Not "show me the log line" - prove it, to someone who does not trust your log, your gateway, or your database. Which key approved it? Were those the exact arguments that were approved, or did something rewrite them after approval? Was that approval already used once? If your answer to any of those starts with "well, our gateway checks that," then the proof lives in your infrastructure, not in the message. Replay the message somewhere else and the proof is gone. This is the gap I have been working on. It has a name worth stating plainly: agent security today is inherited from the connection. TLS tells you the tunnel was private. mTLS tells you which service opened it. A bearer token tells you someone had a credential. None of that survives the message being written to a queue, forwarded by a relay, logged, replayed, or handed to a second agent. The moment a message leaves the connection it arrived on, it is just bytes with no provable origin. N-AALP is my attempt to close that. It is an application-layer object protocol where the message, not the connection, is the unit of security and governance. Full disclosure before you read further: I wrote it. I am the sole editor and maintainer, it is draft-bubblefish-naalp-00, an Independent Submission, and it claims no IETF working-group consensus. I would rather you read the spec and tell me where I am wrong than take my word for anything below. There is a section at the end listing what it does not do. The one-object idea Every N-AALP message is one signed object. Not a request type, not an envelope-plus-payload, not a header format with a body convention. One structure, one signature, one identity model, one authorization model, one audit model, an

When it's less about the product and more about the FCC.

Cybersecurity experts told TechCrunch that one of the biggest lessons to be taken from the OpenAI hack against Hugging Face has nothing to do with AI, but traditional cybersecurity defense.

The U.S. federal consumer watchdog said Hims & Hers, which prescribes for sexual wellness and mental health conditions, used website trackers to share customers' information with advertisers.

If the generative AI giant had followed well-known security best practices, it’s likely that its AI agent would never have escaped to the open internet and hacked multiple companies.

What to know about python static file security when using StayPresent's web.html/markdown — directory exposure, path traversal, and URL filtering. Security Notes for Serving Static Files with StayPresent Serving a status dashboard or a rendered README with web.html() / web.markdown() is convenient precisely because it automatically picks up neighboring CSS, JS, and images with no extra configuration. That same convenience has a security dimension worth understanding clearly before you point it at a directory. This covers python static file security as it applies specifically to StayPresent: what's protected automatically, and what's still your responsibility to manage. Table of Contents The Directory-Wide Exposure Behavior Why This Is Intentional Path Traversal Protection The One-Time Directory Warning Markdown-Specific Protections: Escaping Markdown-Specific Protections: URL Scheme Filtering What's Rejected vs What's Allowed Structuring Directories Safely Full Example Best Practices Common Mistakes FAQs Conclusion The Directory-Wide Exposure Behavior When you call web.html("templates/index.html") or web.markdown("docs/guide.md") , StayPresent doesn't just serve that one file — it serves every file in that file's directory , not only the specific CSS/JS/image files actually referenced from the page. This is what makes relative asset links ( href="style.css" , src="images/logo.png" ) work automatically without any extra configuration on your part. The consequence: if a .env file, your bot's own source code, or a .git/ directory happens to sit in that same directory, it becomes downloadable by anyone who requests it by name — whether or not anything on the page actually links to it. templates/ ├── index.html ├── style.css <- intentionally public, referenced from index.html ├── .env <- NOT referenced anywhere, but still reachable Why This Is Intentional This isn't an oversight — it's what makes web.html() / web.markdown() usable with zero configuration for the overwhel

The ban largely affects U.S. imports from China, which currently dominates the global market for making humanoid robots and solar inverters.

This essay was written with Barath Raghavan, and originally appeared in The Guardian . In July, Hugging Face, a company that hosts much of the world’s AI software and open-source AI models, was hacked. A malicious dataset had been used to run code on one of its servers. Whoever was behind it captured internal security credentials and moved through systems over a weekend, running thousands of actions from a swarm of temporary server environments. It looked like the work of a sophisticated criminal group. It was not. It was one of OpenAI’s new, still unreleased GPT models...
