This essay is adapted from a keynote speech delivered at the DEF CON 34 conference in Las Vegas on August 7, 2026. The essay originally appeared in CyberScoop. I want to talk about AI hacking. There are three aspects: people hacking AI systems, people using AI to hack other systems, and AIs hacking systems on their own, not even maliciously. The last two matter more than the first. The third is th [...]
Penlink’s Webloc is an application that locates people using information from the weather, gaming, email, and religious apps on their phone. It’s sold to the police. The tool collects vast quantities of location data from smartphones via commonly used weather, gaming, email and religious apps. It can build a detailed picture of where a smartphone has been over the past 12 months, and u [...]
The cybercrime group Qilin has emerged as the world’s most active ransomware affiliate program, claiming at least 365 victim organizations in the past three months alone. But even top Russian hackers make operational security mistakes, and the administrator of Qilin has made a few key missteps over the last decade that all point to a 36-year-old man living in St. Petersburg, Russia. Operatin [...]
It’s hard to believe how lucrative this crime can be: According to a press release from the United States attorney’s office for the southern district of New York, three men Jacob Soall, Sharon Hazan, and Guy Sheetrit were arrested for using AI to alter and impersonate the voices and images of executives and attorneys at various companies in order to convince employees to send over large [...]
We reproduced CVE-2026-118383, a critical use-after-free in MongoDB Server's primary catch-up process that unauthenticated clients can set up, and explain how to detect and remediate it. [...]
Microsoft did another four-digit patch drop today, releasing updates to fix almost 1,100 security vulnerabilities in its Windows operating systems and supported software. This month’s Patch Tuesday addresses 63 critical flaws — including a zero-day in Microsoft Outlook — and comes amid important security updates from other software makers, including Adobe, Apple, Google and Mozil [...]
It’s a bad one, and it’s been in the code for a decade: A newly disclosed flaw involving OpenSSH and musl, dubbed “*sshole,” allows attackers to log in to certain Alpine Linux and other musl-based Linux accounts configured to block password authentication simply by entering an oversized password. “Oversized” means longer than 256 bytes. Details. Slashdot thread. [...]
Intigriti typically runs two types of hacking events. Live hacking events are targeted engagements where hand-picked ethical hackers are invited to hunt for vulnerabilities in a specific company’s systems. Conference hacking events take place on site at existing industry gatherings, bringing a company’s program to hackers who are already in the vicinity. In this article, the first of two parts, we [...]
Two weeks ago, I attended the [un]prompted AI security conference in San Francisco. It was an excellent event: three days of very dense talks about all aspects of AI security. (My talk was about integrous AI, and I will post it when it is online.) AI security can be divided into three broad topics. It’s important for researchers to understand which one they are working on. And it’s imp [...]
We share in-the-wild activity from ARTEX, an AI-native penetration framework, against AWS environments, including CloudWatch log hunting with compromised access keys and abuse of public Cognito user pools. [...]
News story: “Scientists discover a bizarre Jurassic ‘squid’ unlike anything ever seen.” Scientists have identified the “fattest” belemnite ever discovered, a bizarre, barrel-shaped squid relative that lived in Wyoming’s ancient seas 160 million years ago. The exceptionally rare fossils reveal a creature unlike anything previously known, potentially a preda [...]
This is fascinating: The video describes a technique that can reveal where an otherwise unidentifiable recording was made by analyzing its audio for the faint sounds of passing aircraft. The technique is both fascinating and frightening. It works by looking at Doppler curves, which plot the way a plane’s sound changes as it passes overhead because of the Doppler effect. This is the same familiar D [...]
Binance’s October 2026 security incident raises an operational question for every organization holding user funds: Can your security controls recognize when a valid signature grants an attacker wallet authority? If an organization only monitors transfers and ownership changes, it may miss the shift in wallet authority until assets move. Binance’s initial update about the incident suggested that a [...]
Several staffers at the White House are using computers or mobile devices equipped with residential proxy services that render their internet address available for others to rent, security experts warned today. One of the proxy services is a Russian company whose founder’s web hosting business was ground zero for cyberattacks against election systems in Arizona and Illinois in 2016. The secu [...]
For the last year, a version of the same conversation has followed me from customer calls to conference hallways and back into internal meetings. I get asked, usually with a mix of both curiosity and anxiety, “Is AI pentesting about to replace bug bounty?” And I keep giving the same answer. Which is a resounding ‘No’. This is not because I think AI is weak, or because I think the hype is harmless. [...]
In both a 2021 essay and my 2022 book, A Hacker’s Mind, I talk about AIs finding vulnerabilities and exploits—hacking—the legal system. Here’s some demonstrations of this from Germany: Legal systems encode the foundations of social order in natural language. Similar to computer systems, the written law can contain vulnerabilities that invite exploitation.1 Courts absorb mos [...]
As millions of Americans vote in today’s U.S. midterms, most will use paper ballots, which are protected by strict chain-of-custody protocols and, in some cases, statistical audits. You may wonder why we still use paper for our elections and voting systems when tasks like banking, tax filing, and document signing have moved away from paper-based legacy systems and become fully electronic. The shor [...]
Google said today it worked with industry partners to dismantle a botnet made up of more than 1.3 million Android TV set-top boxes that ship with malicious software which secretly rents the user’s Internet connection out to strangers and conducts advertising fraud. Experts involved in the takedown say the action is likely to sever the botnet’s access to more than 10 million additional [...]
A comment: 3% of ‘critical’ software security bugs, in all of recorded history, have been found in the last month. This is on pace to find another ~100,000 bugs this year alone, adding ~26% more vulnerabilities to the all time total Do you realize how fucking insane that is? Yes. It is a new world out there. [...]
Stable Linux releases lack existing security fixes because backporting them is time-consuming and often thankless work. We’re using Codex to reduce the backporting process time from days to hours per fix, empowering human patch reviewers to rapidly submit fixes for critical software like Ubuntu Long Term Support, Fedora, and the Linux kernel. By October 29, our project helped deliver fixes for 149 [...]
PHP2Shell made organizations from all over the world scramble to inventory all their PHP assets, and the advice was consistent: patch your instances. But its severity score of 9.2 only tells you how bad PHP2Shell could be, not whether it will be. As a crowd-sourced security platform, we have the ability to view events like PHP2Shell and Log4Shell through a much clearer lens. We process reports, va [...]

PHP2Shell (CVE-2026-109618 and CVE-2026-109619) became the latest vulnerability to grab headlines around the globe. By some estimates, up to 70% of websites run at least some PHP. So if you're respons [...]
PHP remains one of the most widely deployed server-side languages on the web. Estimates suggest it powers close to 70% of all websites, from small personal blogs to large-scale government services, banking platforms, and e-commerce applications. With such huge presence, any vulnerability in PHP's core engine carries the potential to affect a significant portion of the web. On October 21st, 2026, t [...]
Expect to see quite a few websites serving error pages today: Nearly 70 percent of websites need to update their core software to fix a pair of vulnerabilities that allow an attacker to seize full control over affected servers. Experts say there are working exploits for the flaws, and that these critical bugs are already being exploited in the wild. Image: Shutterstock.com, Sashkin. The flaws at i [...]
Today we’re publishing patching-bugs and regression-hunt, two plugins that let engineers delegate patch development and regression checks to agents. Our patching-bugs plugin reproduces reported bugs, develops fixes, and tests them. The regression-hunt plugin checks whether any changes break previously working and supported behavior. Engineers can direct the work and review their results; maintaine [...]
Why the latest Intigriti platform data challenges the notion that AI could replace bug bounty. How researchers are moving from single prompts to multi-agent, always-on workflows. Why AI raises the baseline for vulnerability discovery while the crowd expands its upper limit. What CrowdRecon is teaching us about the coverage already created by hacker reconnaissance. Why coordination, validation, and [...]

Across the bug bounty ecosystem, providers are moving ID verification on platforms earlier in the researcher journey. This is an industry-wide change. ID verification was historically a payout requirement, but it has now shifted to a submission requirement for programs that offer monetary rewards. Researchers who have completed ID verification tend to produce a higher signal ratio than researchers [...]

The United Kingdom has issued economic sanctions against Cryptomus, a chameleonic cryptocurrency platform that experts say serves as a major conduit for payments related to ransomware, narcotics, darknet markets, fraud and cybercrime services that are helping Russia circumvent existing financial restrictions. Heleket’s support agent on Telegram claims, despite all evidence to the contrary, t [...]
I tested 25 of the most popular package managers to check whether they detect a compromised package repository injecting malicious code into legitimate packages. This code integrity problem could be solved using cryptographic hashes or signatures, but many package managers are still vulnerable to this threat. Of the 25 package managers reviewed1, fewer than half used lockfiles that checked for tam [...]
Microsoft today issued updates to fix more than 1,400 security vulnerabilities in its Windows operating systems and other software. Today’s epic patch batch dwarfs September’s record of nearly 1,000 fixes, which was already about ten times the normal monthly patch load from Redmond. Just one of the weaknesses patched this week is considered a “zero day,” or already exploit [...]
Agents with the Federal Bureau of Investigation (FBI) on Thursday arrested an executive at a Canadian cybersecurity firm in connection with an investigation into the ShinyHunters hacking group that recently relieved the FBI of sensitive data on thousands of agents, multiple sources tell KrebsOnSecurity. The New York Times reported today that the FBI has arrested a Canadian man in Pennsylvania on s [...]
A teenager from Amman, Jordan suspected of leading the prolific data theft and extortion group ShinyHunters has been detained and is reportedly cooperating with the FBI to identify other members of the hacking gang. KrebsOnSecurity has learned that the suspect, who uses the hacker handle “Rey,” was detained as ShinyHunters was in the process of extorting a business unit recently divest [...]
Security teams have more ways than ever to map assets, scan infrastructure, and track vulnerabilities. Yet one question often remains difficult to answer: what does a skilled researcher consider worth exploring? That question matters because external exposure is not only a list of internet-facing assets; it is also a set of relationships, assumptions, and possible paths that change as products, do [...]
In this post, we share LLM-specific validation patterns that attackers use to test exposed AWS credentials for Amazon Bedrock access. [...]

Multihashing is one of those cryptographic tasks that’s easy not to think about too much. This is unfortunate, because multihashing is a common stumbling point when cryptographers try to use hashes. As part of our goal to “fix software, not bugs,” Trail of Bits is introducing SequenceHash and its sister function SequenceMAC, a pair of related hash constructions that bring secure multihashing to de [...]
In the summer of 2026, Intigriti celebrated a major milestone: its 10th anniversary! To mark the occasion, the team came together from around the globe. This article shares what they had to say about a decade of Intigriti! Intigriti’s journey shows how a bold idea evolved into a global cybersecurity company combining innovation, strategic investment, and a deeply rooted hacker-first culture. For o [...]
Threshold signature schemes, a form of multi-party computation (MPC) that lets a set of parties sign together without any one of them holding the key, are increasingly deployed inside trusted execution environments (TEEs). The combination is intended to amplify security for sensitive computations: MPC distributes trust across multiple independent parties, while TEEs root trust in the hardware manu [...]

Datadog Security Labs discovered GHSA-632h-h47v-g4x4, a vulnerability in OpenCode's upgrade endpoint that, under certain conditions, allowed malicious webpages to execute code on developers' machines. [...]
Born out of academia and raised in corporate IT departments, the Security Assertion Markup Language (SAML) authentication protocol continues to be a staple in these organizations. However, it’s time for it to retire. With the rise of software-as-a-service (SaaS) companies in the late aughts, IT departments needed a way for users to authenticate to many new web services. SAML and the burgeoni [...]
When the push came to start weaving AI into our everyday work, I had doubts at the start. But I have since come around, and here's why. I'm on the engineering team at Intigriti, but my role is Quality Assurance (QA), so I'm the one writing the tests, running the tests, and then collaborating with the developers when something doesn't work the way it should. That means my day is a mix of automation [...]
Security firms have published numerous blog posts describing how they pointed their agent harness at a codebase and found dozens of bugs (we’re one of them). However, these posts tend to focus on agentic code review, which is just one aspect of how we use AI in our security reviews. We want to give a different perspective: before code review even starts, agents now allow us to build custom tooling [...]
In this post, we examine two vibe-coded credential harvesting platforms, Loot and UltraVault, and the Amazon Bedrock abuse used to validate stolen secrets. [...]

1Password’s FLAWED report, published on August 6, 2026, gives defenders a misleading picture of AI patching. Its headline says models produced clean fixes only 26% of the time. That figure includes experiments that deliberately instructed agents to apply the wrong fix, along with experiments in which agents could not compile or test their patches. The report risks making defenders less effective b [...]
Fermat famously claimed to have a “truly marvelous proof” of his Last Theorem, but he never wrote it down, insisting the margin of his page was too narrow to contain it. A few centuries later, Anthropic announced a complete formalization of Fermat’s Last Theorem using 13 million lines of Lean code (clearly not what Fermat intended). Luckily, we found a wonderfully cursed Lean bug, shown belo [...]

When I wake up in the morning, as a Senior Software Engineer at Intigriti, the first thing I do is make coffee. The second thing I do is pick up exactly where I left off the day before, usually mid-conversation with an AI. That probably sounds a bit strange. And, depending on who you're asking, maybe a little unsettling too. But that's genuinely what my working day looks like now, and I think it's [...]

As AI agents are deployed to automate more tasks, they become more capable. And as the famous quote goes: "With great power comes great responsibility." Assuming that humans in the loop can mitigate that risk turns out to be. At Bug Bounty Village during DEF CON 34, Inti De Ceukelaire, Founding Member of Intigriti, delivered a talk on how attackers can abuse today's AI agents in ways most defender [...]
At Intigriti, we have been exploring a simple but important shift in security: the work that happens before a vulnerability report is often where the real signal begins. As vulnerability discovery accelerates, organizations need practical ways to identify and reduce risk before vulnerabilities are used in attacks. In Reconnaissance for exposure management, I discussed how context turns scanning an [...]
