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 [...]
There’s a new archive of all the papers from twenty-five years of the Workshop on Economics and Information Security (WEIS). Really nice resource. It’s fun to reread my 2002 essay on the economics of information security. [...]
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 [...]

U.S. federal investigators pursuing the ShinyHunters hacking group that recently stole highly sensitive data from the FBI have identified executives at two different ransomware negotiation firms who maintained unusually close relations with the extortion group, KrebsOnSecurity has learned. Sources close to the investigation say one of the executives in the United States even helped ShinyHunters op [...]
Interesting research: Abstract: Vision-language models (VLMs) can solve visual CAPTCHAs without task-specific training, but the agents built on them approach every challenge from scratch. For such an agent, the hundredth instance of a familiar puzzle costs as much time and compute as the first. Specialized detectors invert the trade-off, answering in milliseconds but only for categories they were [...]
We tested Sonnet 5, Composer 2.5, and GPT 5.5 using set security rules to see whether using them produces measurably more secure code. [...]

This is a problem: Any open model whose weights have been edited can carry a backdoor, whether it’s a task-specific fine-tune, a merged adapter or an abliterated build. We have abliterated models in the title because it’s the most popular reason people download modified weights without verifying what’s inside. Abliteration is a cheap fine-tune that takes away a model’s abil [...]
Matthew Green has a new site that tries to estimate the number of cryptanalyst-hours that have been spent analyzing different public-key algorithms: Abstract: We estimate how much public cryptanalysis each public-key assumption has received, using the literature itself as the instrument. From roughly sixteen thousand candidate papers we classify cryptanalytic work on ECDLP, structured and plain la [...]

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 [...]

Matthew Green has been writing a rather pessimistic series of posts about the potential for AI systems to vastly outperform humans in cryptanalysis of both symmetric and public-key ciphers. I am more optimistic than he is. That is, I have stronger faith in the over-engineering cryptographers tend to do. I am trying to write this up in more detail. [...]
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 [...]
Another IoT cyberattack, this one in France: Hackers gained control of the software that regulates the temperatures of the refrigeration units, forcing some to warm to 50C (120F) overnight, according to one supermarket chain affected. […] Normally, supermarket freezers go through a short period of defrosting overnight, in which temperatures rise slightly. But the hackers ordered the units to [...]
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 [...]
In September, hackers from a group called ShinyHunters announced that they stole a trove of FBI data about its own agents. It was an intelligence disaster. Last week, the FBI arrested (alternate link) someone associated with that crime. [...]
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 [...]
Wallarm Infrastructure Discovery Named Enterprise Cloud Security Solution of the Year. Ask an AWS security team how many accounts they run, and the honest answer is usually a range. Enterprises on AWS operate anywhere from 100 to 5,000 accounts. Most security teams can see only a fraction of them. That gap is why we built Wallarm Infrastructure Discovery. This week, it was named Enterprise [...]
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. [...]
We analyzed RBAC bindings across over 65,000 Kubernetes clusters to find dangerous permissions granted to system:anonymous, system:unauthenticated, and system:authenticated. [...]
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 [...]
Answer this without checking: how many AI agents are running in your environment right now? Most security leaders give an estimate and a shrug. That is a fair response, because agents get spun up by an engineer solving a problem on a Tuesday afternoon, through a path that puts them on nobody's radar. In August 2026, researchers found AI agents connected to Hugging Face running loose inside ent [...]
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 [...]
Authorities in the Netherlands have arrested a 24-year-old convicted cybercriminal on suspicion of aiding in data thefts and extortions by the prolific hacker group ShinyHunters. In the days immediately following the suspect’s arrest, remaining ShinyHunters members dramatically escalated their attacks, stealing highly sensitive data from the FBI and extorting the Russian ransomware group Cl0 [...]
A U.S. Army soldier who pleaded guilty to hacking into multiple telecommunications companies and stealing mobile call and text metadata for more than 100 million AT&T customers in 2024 was sentenced to 70 months in federal prison today and ordered to pay nearly $300,000 in restitution to victims. One of several selfies from the Facebook page of Cameron Wagenius. Cameron John Wagenius, 22, was [...]
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. [...]
The consumer data broker Radaris.com has long had a reputation for ignoring requests to remove personal information from its vast empire of people-search services online. That reputation caught up with the company recently in a lawsuit alleging Radaris violated a New Jersey privacy law that provides for hefty fines against data brokers that publish personal information on state law enforcement off [...]
In this post, we walk through different threats to GitHub and how to detect them. [...]
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 [...]
Here's the uncomfortable part first: in August 2026, researchers found AI agents connected to Hugging Face running loose inside enterprise networks. No owner, no audit trail, nobody who could tell you they existed until something broke. If that sentence made your stomach drop a little, good, because it should. It's the same blind spot most security teams are sitting on right now. They just haven' [...]
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 [...]
Microsoft Corp. today issued updates to plug at least 974 security holes in its Windows operating systems and other software, by far its biggest single patch batch ever. Microsoft says artificial intelligence is helping to speed the discovery of vulnerabilities, but security experts warn that many organizations already are struggling to prioritize the more human-intensive endeavor of testing and d [...]

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 [...]

The volume of published incident research involving agentic AI is increasing, and the analysis that follows each report tends to concentrate on the same attribute: speed. The recent investigation from Unit 42, the threat intelligence and incident response group at Palo Alto Networks, is a representative case. A human operator delegated tactical execution to frontier AI agents, compressing what wo [...]

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 [...]
