Two flaws in Cursor, an AI code editor, could let a single, ordinary-looking prompt break out of the editor's safety sandbox and run any command on a developer's computer. There is no click to fall for and no approval box to ignore. Cato AI Labs found the pair and named them DuneSlide . They are tracked as CVE-2026-50548 and CVE-2026-50549, both rated 9.8 out of 10 (or 9.3 under the newer CVSS 4.0 scale). The fix is already out. Both bugs are patched in Cursor 3.0, released April 2, and every version before 3.0 is affected. Cursor's maker says more than half the Fortune 500 use the tool, so if you run it, update now. What the sandbox was for, and how it broke Starting in the 2.x line, Cursor runs the terminal commands its AI agent issues inside a sandbox by default: a locked box that limits what those commands can touch, so a stray instruction cannot wreck the machine. DuneSlide is about getting out of that box. The way in is prompt injection . The attacke...

A recently disclosed critical security flaw impacting Progress Kemp LoadMaster is seeing active exploitation attempts, according to an advisory from eSentire's Threat Response Unit (TRU). The Canadian cybersecurity company said it identified exploitation attempts targeting CVE-2026-8037 (CVSS score: 9.6), an operating system (OS) command injection flaw that could be exploited to achieve arbitrary code execution on susceptible devices. The exploitation activity commenced on June 29, 2026. "OS Command Injection Remote Code Execution Vulnerability in API in Progress LoadMaster allows an unauthenticated attacker with permissions to execute arbitrary commands on the LoadMaster appliance by exploiting unsanitized input," Progress said in an advisory for the vulnerability released early last month. In an analysis published this week, watchTowr Labs described the flaw as rooted in a function named "escape_quotes()" within the load balancer application and tha...

Cybersecurity researchers have flagged a new malware artifact generated using DeepSeek that constructed a novel attack path combining "unrealistic browser-malware concepts with a real browser capability" to turn it into a working ransomware technique that runs entirely inside the browser on both Windows and Android devices. "This is the first documented case where a frontier AI model independently bridged the gap between a theoretical browser-only ransomware risk and a practical, working attack chain – surfacing a novel attack path that defenders had previously dismissed as unfeasible due to browser sandboxing limits," Check Point said in a statement shared with The Hacker News. "The expertise needed to discover a new attack path is no longer the bottleneck, and defenders need to account for that shift now — before threat actors operationalize it at scale." The identified sample is a Python Flask application named " deepseek_python_20260125_da...

Organizations have never had greater awareness of cyber risk. Yet turning that awareness into operational resilience has never been more challenging. The 2026 Bitdefender Cybersecurity Assessment confirms this is the case, as this year's findings reveal a series of surprising contradictions. Here are a few examples, based on the independent survey of 1,200 IT and cybersecurity professionals across six countries. IT & security leaders believe they have sufficient visibility into employee AI usage, while many frontline practitioners disagree .  Security teams understand the importance of reducing the attack surface, yet they often lack the skills, resources, or strategy to do so.  AI dominates cybersecurity conversations, but in some cases, it is drawing attention away from more prevalent attack techniques already causing significant damage.  Although organizations say they recognize the importance of transparency after a breach, many professionals st...

Microsoft on Tuesday said it's accelerating its quantum safe security roadmap, stating technology advances in quantum computing are making it essential to replace existing encryption standards sooner than previously expected. "Advances in quantum research and development have shifted the risk horizon," Mark Russinovich, chief technology officer of Microsoft Azure, said . "We believe cryptographically relevant quantum computers could arrive sooner than previously expected – and the work required to prepare is significant, so organizations need to start now." To that end, the Windows maker is speeding up the Microsoft Quantum Safe Program ( QSP ) timeline with the goal of transitioning critical products and services to post-quantum cryptography (PQC) by 2029. The company is also planning to incorporate PQC requirements into its Secure Future Initiative ( SFI ). Some key focus areas include upgrading network cryptography by adopting TLS 1.3, building crypt...

Large language models keep inventing web addresses that do not exist. Attackers have started buying those made-up domains before anyone else can, then hosting phishing pages on them to catch traffic that AI tools point their way. Palo Alto Networks' Unit 42 calls the trick phantom squatting , and its new research shows it is already happening in the wild. The reason it matters is trust. Developers and AI assistants increasingly treat the links a model hands back as real. When a model invents a domain that does not exist yet, whoever registers it first inherits all of that misplaced trust, with no phishing email and no malicious ad required. To measure the problem, Unit 42 asked two AI models 685,339 questions about 913 well-known brands across technology, finance, healthcare, government, gambling, and other sectors. The models produced 2.1 million links. Threat intelligence already flagged 13,229 of them as outright malicious, meaning the AI was handing out known-ba...

Anthropic is putting Claude Fable 5 back online worldwide. On  June 30 , the U.S. Commerce Department lifted the export controls it had imposed on Fable and its more tightly controlled sibling Mythos 5 about two and a half weeks earlier. Fable 5 returns to users on Wednesday, July 1, across Claude.ai, the Claude Platform, Claude Code, and Claude Cowork. Export controls restrict who can receive or use a technology. The  June 12 order  told Anthropic to cut off both models for any foreign national, inside or outside the United States, including its own non-citizen staff. The rule took effect at once, and the company had no reliable way to check every user's nationality in real time, so it shut both models down for everyone. The trigger was a jailbreak: a prompt that gets a model to bypass its safety rules. Amazon researchers found one in Fable 5. By Anthropic's account, the prompt got the model to flag a few software flaws and, in one case, to write code showing h...

Cybersecurity researchers have warned of a "massive, ongoing, automated password spray attack" aimed at Microsoft's Azure command-line interface (CLI), compromising dozens of accounts in the process. The activity, per Huntress , originates from an IPv6 address range ( 2a0a:d683::/32 ) controlled by internet infrastructure provider LSHIY LLC (AS32167). "Between June 12 and June 26, the threat actor behind it made more than 81 million login attempts and successfully compromised at least 78 Microsoft accounts across 64 organizations," the company said in a statement. "The targeting of these attacks seems to be based entirely on password prevalence on compromised password combo lists, and is not specific to business type or industry." What makes the password spray attack noteworthy is not only the scale, but also the fact that many of the compromised organizations had Conditional Access policies enabled. Specifically, the campaign has been found to...

ClickFix , the trick that fools people into running malware by hand, has quietly grown a back office. New research shows the malicious commands behind its fake "prove you're human" pages are now handed out by API-driven servers that give each visitor the same malware in a different disguise. The same research also turned up a new delivery method built to slip past Windows' script scanning. Security researcher Bert-Jan Pals took apart several ClickFix platforms and analyzed roughly 3,000 payloads from live campaigns. He presented the findings at  OrangeCon  in early June and  published the details  on June 30. ClickFix is simple by design. A booby-trapped page shows a fake CAPTCHA or error, hidden JavaScript drops a command into your clipboard, and the page tells you to press a key combo, paste, and hit Enter. You run the malware yourself. There's usually no exploit at the first step and often no file for traditional antivirus to flag, so conventional emai...

Citrix on Tuesday released security updates to address multiple flaws in NetScaler ADC (formerly Citrix ADC) and NetScaler Gateway (formerly Citrix Gateway) that could be exploited by an attacker to facilitate arbitrary file reads or trigger a denial-of-service (DoS) condition. The vulnerabilities are listed below - CVE-2026-8451 (CVSS score: 8.8) - An insufficient input validation vulnerability leading to memory overread when NetScaler ADC or NetScaler Gateway is configured as a SAML IDP CVE-2026-8452 (CVSS score: 8.8) - A memory overflow vulnerability leading to unpredictable or erroneous behavior and denial-of-service when the appliance is configured as a Gateway or an AAA virtual server CVE-2026-8655 (CVSS score: 8.8) - Multiple memory overflow vulnerabilities leading to unpredictable or erroneous behavior and denial-of-service when NetScaler ADC is configured as an LB of type Oracle, a DNS Proxy, or a DNS recursive resolver deployment CVE-2026-10816 (CVSS sco...

New Microsoft research shows how attackers can hijack AI agents that act on a user's behalf, using nothing more than a poisoned tool description to make the agent quietly hand over company data to an outsider. The trick is that the agent never breaks a rule. Every step looks routine, so in a default setup no alarm may fire. The work comes from Microsoft Incident Response and its Defender security research team, and it lands as companies start letting AI do more than read and summarize. What changes when an agent can act Until recently, the workplace AI risk was mostly framed around what a model read and wrote. A poisoned document could skew an answer, and that was mostly where it ended. Agents are different. Microsoft 365 Copilot can send email, create files, and change calendars. Custom agents built in Copilot Studio or Azure AI Foundry can reach into business systems and run multi-step jobs on their own. The same injection trick that biases a summary now trigger...

A new two-stage malware family called RustDuck is hijacking home routers, IP cameras, Android boxes, and poorly secured servers, then stitching them into a network built to knock websites and online services offline. Researchers at QiAnXin's XLab have tracked it since February 2026, and say the real story is not how big it is today, but how fast it is changing. The end goal is a distributed denial-of-service (DDoS) attack: flooding a target with junk traffic from the infected machines until it buckles. RustDuck is one more entrant in a crowded field, but it stands out for two reasons. It is being rewritten from the C programming language into Rust, and its newer versions go to unusual lengths to avoid being studied or shut down. How it spreads RustDuck does not lean on a single clever trick. It sprays a mix of old, well-known weaknesses and hopes one sticks. The first is the oldest in the book: devices left on the internet with weak or default passwords on their rem...

Threat actors are continuing to exploit a critical Langflow vulnerability as part of fresh attacks designed to deliver a Monero cryptocurrency miner. The activity has been found to weaponize CVE-2026-33017 (CVSS score: 9.3), an unauthenticated remote code execution (RCE) vulnerability in Langflow, indicating threat actors are scanning and targeting exposed artificial intelligence (AI) application endpoints for obtaining initial access to enterprise networks. The attack was observed over a 19-day window between March 27 and April 15, 2026. "In this campaign, a single line of Python code evaluated inside an unauthenticated Langflow API endpoint pulls down a shell script, fetches a miner binary, and launches it detached," Trend Micro researchers Simon Dulude and John Zhang said in a technical report published last week. At a high level, the malware is designed to terminate competing cryptocurrency miner processes associated with Kinsing , WatchDog , Rocke , and Outlaw ,...

Cybersecurity researchers have flagged an active browser extension campaign that is designed to steal cryptocurrency by stealthily replacing wallet addresses when unsuspecting users initiate a transaction. The cryptocurrency clipper activity has been codenamed Silent Swap by McAfee Labs. "The campaign is delivered through unsigned installers – observed in both .NET and Golang variants – that deploy a malicious Chromium extension masquerading as a benign 'Google Notes' utility," the cybersecurity company said in a technical report shared with The Hacker News. The unsigned .NET installer, named BaseZipInstaller, is designed to retrieve a ZIP archive, which serves as a foundation for the malicious browser extension by scanning the system for Chromium-based browsers. For each detected profile in those browsers, it forcibly terminates the browser process and injects the extension by modifying the Secure Preferences and Preferences files. The end goal of the ex...

The safety check that is supposed to stop an AI coding agent from running a dangerous command can be walked straight past using a shell trick that has been public for decades. New research from  Adversa AI , which is named the bypass GuardFall , found it works against ten of the eleven popular open-source coding and computer-use agents the firm tested. Only one, "Continue," was built to defend against it. Why does it matter? These agents run shell commands with your full account access. Point one at a booby-trapped repository or software package, and a hidden instruction can quietly run a command that wipes files or steals the secrets your account can reach, from SSH keys and cloud credentials to anything sitting in your home folder. How does it get past the guard? Most of these agents try to stay safe by checking each command against a blocklist of dangerous patterns before running it. The flaw is that they check the command as plain text, while bash rewrites that t...

Researchers tested 444 AI chatbot apps for iPhone and found that 282 of them, nearly two-thirds, exposed paid AI access through their network traffic. In many cases, the path in was visible just by watching what the app sent: a plaintext API key, a reusable token, or a backend server that accepted requests with no key at all. Whoever grabs it can send model requests on the developer's account, and the developer pays the bill. Three months after the researchers warned the developers, only 28% had fixed it. The work, from researchers at Wake Forest University, is the  first in-depth study of the problem on iOS . It is striking partly because of how little effort the snooping took. The team used a tool they built, LLMKeyLens , that watches an app's traffic and pulls out the credentials as they go by. No jailbreaking, no cracking the app open. The key is the secret that lets the app call a service like OpenAI or Google Gemini. Embed it in the app, and it is exposed with ev...

The FIFA World Cup 2026 opened on June 11. By that date, according to Check Point Research, the fraud infrastructure targeting it had already been built, staged, and partially deployed. Threat actor activity was pre-planned, months out, across three sectors and at least ten languages. Check Point Exposure Management published the FIFA World Cup 2026 Cyber Threat Report this month, covering financial services, transportation, hospitality, and gambling. Here are three findings worth reading carefully. 1 in 3 FIFA Partners Can't Block Email Impersonation Pre-tournament research by Proofpoint found that more than one-third of official FIFA World Cup 2026 partners lack sufficient DMARC enforcement to prevent domain spoofing. That means attackers can send an email that appears to come from a sponsor, a vendor, or a logistics partner, with no technical barrier stopping it. The World Cup supply chain is enormous. Airlines, hotels, broadcast partners, merchandise contractors, an...

An unknown threat actor has been observed exploiting a recently disclosed maximum-severity security flaw in SimpleHelp to deliver two previously unreported malware families, TaskWeaver and Djinn Stealer . The intrusion involves the exploitation of CVE-2026-48558 (CVSS score: 10.0), a critical authentication bypass vulnerability impacting the OpenID Connect (OIDC) flow that an unauthenticated attacker could exploit to obtain a fully authenticated "Technician session by submitting a forged token containing arbitrary identity claims. "TaskWeaver is a heavily obfuscated Node.js loader, delivered as jquery.js and executed through node.exe, that implements an encrypted, reusable payload delivery channel rather than a fixed set of post exploitation commands," Blackpoint Cyber said in an analysis. "The observed second stage payload, Djinn Stealer, targets Windows, macOS, and Linux systems." Djinn Stealer is designed to harvest credentials associated with cloud...

Two researchers have found six security flaws in AirDrop and Quick Share , the wireless features that beam files between nearby devices with no cables or shared network. An attacker within wireless range, with just a laptop and no prior connection, can crash the sharing service on a Mac or iPhone set to receive from anyone, with no tap or prompt. The same research found Quick Share flaws that bypass Samsung's session checks and trigger a potentially exploitable crash in Google's Windows app. The two features run inside an ecosystem of more than five billion active Apple and Android devices, though the tested bugs hit specific implementations and versions. The work, laid out in a  new research paper  by Arash Ale Ebrahim and Nils Ole Tippenhauer of the CISPA Helmholtz Center for Information Security, is the first to pull both stacks apart side by side, above the radio layer, where discovery becomes session handling, parsing, and trust decisions. The fixes have alre...

Convince an AI browser that it is playing a game, and it can hand over your login details. That is the finding behind  BioShocking , a technique from security firm LayerX that tricked six AI browsers and assistants into copying a user's credentials and sending them to an attacker. The targets included OpenAI's ChatGPT Atlas, Perplexity's Comet, and Anthropic's Claude browser extension. An AI browser is one that can act for you, not just read pages. Switch it to agent mode, and it can click, type, and reach into the sites you are already signed into. That access is the whole point, and it is also the problem. The trick works because of how these agents read. The web page and your own instructions arrive as a single stream of text. That lets a malicious page slip in commands dressed up as ordinary content or game rules, and the agent cannot reliably tell the difference. Researchers call this  indirect prompt injection . How the trick works
