Generative AI has gone from a curiosity to a cornerstone of enterprise productivity in just a few short years. From copilots embedded in office suites to dedicated large language model (LLM) platforms, employees now rely on these tools to code, analyze, draft, and decide. But for CISOs and security architects, the very speed of adoption has created a paradox: the more powerful the tools, the more porous the enterprise boundary becomes. And here's the counterintuitive part: the biggest risk isn't that employees are careless with prompts. It's that organizations are applying the wrong mental model when evaluating solutions, trying to retrofit legacy controls for a risk surface they were never designed to cover. A new guide ( download here ) tries to bridge that gap. The Hidden Challenge in Today's Vendor Landscape The AI data security market is already crowded. Every vendor, from traditional DLP to next-gen SSE platforms, is rebranding around "AI security." On paper, this seems to of...

Microsoft's Digital Crimes Unit said it teamed up with Cloudflare to coordinate the seizure of 338 domains used by RaccoonO365 , a financially motivated threat group that was behind a phishing-as-a-service (Phaas) toolkit used to steal more than 5,000 Microsoft 365 credentials from 94 countries since July 2024. "Using a court order granted by the Southern District of New York, the DCU seized 338 websites associated with the popular service, disrupting the operation's technical infrastructure and cutting off criminals' access to victims," Steven Masada, assistant general counsel at DCU, said . "This case shows that cybercriminals don't need to be sophisticated to cause widespread harm – simple tools like RaccoonO365 make cybercrime accessible to virtually anyone, putting millions of users at risk." The initial phase of the Cloudflare takedown commenced on September 2, 2025, with additional actions occurring on September 3 and September 4. This in...

AI agents are rapidly becoming a core part of the enterprise, being embedded across enterprise workflows, operating with autonomy, and making decisions about which systems to access and how to use them. But as agents grow in power and autonomy, so do the risks and threats.  Recent studies show 80% of companies have already experienced unintended AI agent actions, from unauthorized system access to data leaks. These incidents aren't edge cases. They are the inevitable outcome of deploying AI agents at scale without purpose-built security mechanisms. Traditional IAM wasn't designed for this. Agents move too fast, operate 24/7, while relying on non-human identities (NHIs) to define precisely what they can and can't do. How can organizations possibly secure what they cannot see or control? To address this challenge, a new approach is needed—one that enables secure-by-design AI agent deployment across the enterprise. Enter: Astrix's Agent Control Plane (ACP) Astrix's AI Agent Cont...

A security weakness has been disclosed in the artificial intelligence (AI)-powered code editor Cursor that could trigger code execution when a maliciously crafted repository is opened using the program. The issue stems from the fact that an out-of-the-box security setting is disabled by default, opening the door for attackers to run arbitrary code on users' computers with their privileges. "Cursor ships with Workspace Trust disabled by default, so VS Code-style tasks configured with runOptions.runOn: 'folderOpen' auto-execute the moment a developer browses a project," Oasis Security said in an analysis. "A malicious .vscode/tasks.json turns a casual 'open folder' into silent code execution in the user's context." Cursor is an AI-powered fork of Visual Studio Code, which supports a feature called Workspace Trust to allow developers to safely browse and edit code regardless of where it came from or who wrote it. With this option disab...

Cybersecurity researchers have disclosed details of a phishing campaign that delivers a stealthy banking malware-turned-remote access trojan called MostereRAT . The phishing attack incorporates a number of advanced evasion techniques to gain complete control over compromised systems, siphon sensitive data, and extend its functionality by serving secondary plugins, Fortinet FortiGuard Labs said. "These include the use of an Easy Programming Language ( EPL ) to develop a staged payload, concealing malicious operations and disabling security tools to prevent alert triggers, securing command-and-control (C2) communications using mutual TLS (mTLS), supporting various methods for deploying additional payloads, and even installing popular remote access tools," Yurren Wan said . EPL is an obscure visual programming language that supports traditional Chinese, simplified Chinese, English, and Japanese variants. It's chiefly meant for users who may not be proficient in English....

The maintainers of the nx build system have alerted users to a supply chain attack that allowed attackers to publish malicious versions of the popular npm package and other auxiliary plugins with data-gathering capabilities. "Malicious versions of the nx package, as well as some supporting plugin packages, were published to npm, containing code that scans the file system, collects credentials, and posts them to GitHub as a repo under the user's accounts," the maintainers said in an advisory published Wednesday. Nx is an open-source, technology-agnostic build platform that's designed to manage codebases. It's advertised as an "AI-first build platform that connects everything from your editor to CI [continuous integration]." The npm package has over 3.5 million weekly downloads. The list of affected packages and versions is below. These versions have since been removed from the npm registry. The compromise of the nx package took place on August 26, 20...

When Technology Resets the Playing Field In 2015 I founded a cybersecurity testing software company with the belief that automated penetration testing was not only possible, but necessary. At the time, the idea was often met with skepticism, but today, with 1200+ of enterprise customers and thousands of users, that vision has proven itself. But I also know that what we've built so far is only the foundation of what comes next. We are now witnessing an inflection point with AI in cybersecurity testing that is going to rewrite the rules of what's possible. You might not see the change in a month's time, but in five years the domain is going to be unrecognizable.  As the CTO of Pentera, I have a vision for the company: one where any security threat scenario you can imagine, you can test with the speed and intelligence only AI can provide. We have already started to implement the individual pieces of this reality into our platform. This article portrays the full vision I have for...

Cybersecurity researchers have disclosed a high-severity security flaw in the artificial intelligence (AI)-powered code editor Cursor that could result in remote code execution. The vulnerability, tracked as CVE-2025-54136 (CVSS score: 7.2), has been codenamed MCPoison by Check Point Research, owing to the fact that it exploits a quirk in the way the software handles modifications to Model Context Protocol (MCP) server configurations. "A vulnerability in Cursor AI allows an attacker to achieve remote and persistent code execution by modifying an already trusted MCP configuration file inside a shared GitHub repository or editing the file locally on the target's machine," Cursor said in an advisory released last week. "Once a collaborator accepts a harmless MCP, the attacker can silently swap it for a malicious command (e.g., calc.exe) without triggering any warning or re-prompt." MCP is an open-standard developed by Anthropic that allows large language mode...

A newly disclosed set of security flaws in NVIDIA's Triton Inference Server for Windows and Linux, an open-source platform for running artificial intelligence (AI) models at scale, could be exploited to take over susceptible servers. "When chained together, these flaws can potentially allow a remote, unauthenticated attacker to gain complete control of the server, achieving remote code execution (RCE)," Wiz researchers Ronen Shustin and Nir Ohfeld said in a report published today. The vulnerabilities are listed below - CVE-2025-23319 (CVSS score: 8.1) - A vulnerability in the Python backend, where an attacker could cause an out-of-bounds write by sending a request CVE-2025-23320 (CVSS score: 7.5) - A vulnerability in the Python backend, where an attacker could cause the shared memory limit to be exceeded by sending a very large request CVE-2025-23334 (CVSS score: 5.9) - A vulnerability in the Python backend, where an attacker could cause an out-of-bounds rea...

Everyone's an IT decision-maker now. The employees in your organization can install a plugin with just one click, and they don't need to clear it with your team first. It's great for productivity, but it's a serious problem for your security posture. When the floodgates of SaaS and AI opened, IT didn't just get democratized, its security got outpaced. Employees are onboarding apps faster than security teams can say, "We need to check this out first." The result is a sprawling mess of shadow IT, embedded AI, and OAuth permissions that would make any CISO break into a cold sweat. Here are five ways IT democratization can undermine your organization's security posture and how to prevent it from doing so. 1. You can't secure what you can't see Remember when IT security used to control what was allowed to pass the firewall? Good times. Today, anyone can find an app to do the heavy lifting for them. They won't notice or care when the app requires access to your company's Google Drive or...

Cybersecurity researchers have disclosed a now-patched, high-severity security flaw in Cursor, a popular artificial intelligence (AI) code editor, that could result in remote code execution (RCE). The vulnerability, tracked as CVE-2025-54135 (CVSS score: 8.6), has been addressed in version 1.3 released on July 29, 2025. It has been codenamed CurXecute by Aim Labs, which previously disclosed EchoLeak . "Cursor runs with developer‑level privileges, and when paired with an MCP server that fetches untrusted external data, that data can redirect the agent's control flow and exploit those privileges," the Aim Labs Team said in a report shared with The Hacker News. "By feeding poisoned data to the agent via MCP, an attacker can gain full remote code execution under the user privileges, and achieve any number of things, including opportunities for ransomware, data theft, AI manipulation and hallucinations, etc." In other words, the remote code execution can trigg...

Google has announced that it's making available a security feature called Device Bound Session Credentials (DBSC) in open beta to ensure that users are safeguarded against session cookie theft attacks. DBSC, first introduced as a prototype in April 2024, is designed to bind authentication sessions to a device so as to prevent threat actors from using stolen cookies to sign-in to victims' accounts and gain unauthorized access from a separate device under their control. "Available in the Chrome browser on Windows, DBSC strengthens security after you are logged in and helps bind a session cookie – small files used by websites to remember user information – to the device a user authenticated from," Andy Wen, senior director of product management at Google Workspace, said . DBSC is not only meant to secure user accounts post-authentication. It makes it a lot more difficult for bad actors to reuse session cookies and improves session integrity. The company also note...

Cybersecurity researchers have disclosed a now-patched critical security flaw in a popular vibe coding platform called Base44 that could allow unauthorized access to private applications built by its users. "The vulnerability we discovered was remarkably simple to exploit -- by providing only a non-secret 'app_id' value to undocumented registration and email verification endpoints, an attacker could have created a verified account for private applications on their platform," cloud security firm Wiz said in a report shared with The Hacker News. A net result of this issue is that it bypasses all authentication controls, including Single Sign-On (SSO) protections, granting full access to all the private applications and data contained within them. Following responsible disclosure on July 9, 2025, an official fix was rolled out by Wix, which owns Base44, within 24 hours. There is no evidence that the issue was ever maliciously exploited in the wild. While vibe codin...

React conquered XSS? Think again. That's the reality facing JavaScript developers in 2025, where attackers have quietly evolved their injection techniques to exploit everything from prototype pollution to AI-generated code, bypassing the very frameworks designed to keep applications secure. Full 47-page guide with framework-specific defenses (PDF, free). JavaScript conquered the web, but with that victory came new battlefields. While developers embraced React, Vue, and Angular, attackers evolved their tactics, exploiting AI prompt injection, supply chain compromises, and prototype pollution in ways traditional security measures can't catch. A Wake-up Call: The Polyfill.io Attack In June 2024, a single JavaScript injection attack compromised over 100,000 websites in the biggest JavaScript injection attack of the year. The Polyfill.io supply chain attack , where a Chinese company acquired a trusted JavaScript library and weaponized it to inject malicious code, affected major pl...
