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...
