Claude Cowork Flaw Could Let AI Agent Escape Its VM and Access Mac Files

Cybersecurity researchers have uncovered a sandbox escape vulnerability in Anthropic’s Claude Cowork that makes it possible to break out of the confines of a Linux virtual machine (VM) within which the agent runs to read or write files anywhere on the Mac. Accomplish AI, which shared details of the vulnerability with The Hacker News ahead of publication, said about 500,000 macOS users running

How attackers hosted a fake Claude download page on the claude.ai domain

A threat actor abused Anthropic’s Claude Artifacts feature to funnel users toward malware, Huntress researchers have disclosed. Employees at at least 29 organizations were compromised over two days in July, after searching for the Claude desktop app and clicking a sponsored Bing ad. The ad pointed to the genuine claude.ai domain, but landed on an attacker-published public artifact, which redirected them to a spoofed download site serving SectopRAT. What are Claude Artifacts? Artifacts are a … More → The post How attackers hosted a fake Claude download page on the claude.ai domain appeared first on Help Net Security.

Chaos Ransomware Uses msaRAT to Route C2 Traffic Through Headless Chrome and Edge

The Chaos ransomware group ran its command-and-control through the victim’s own browser. Cisco Talos on Thursday detailed msaRAT, the Rust implant behind it, found on a compromised Windows machine ahead of the encryptor. The implant never opens an outbound connection of its own. Its process talks to 127.0.0.1 and nothing else. It starts Chrome or Edge in headless mode and drives the browser

Cobalt adds Autonomous Pentest to scale application security testing

Cobalt has introduced Cobalt Autonomous Pentest, a new offering that enables continuous offensive security across an organization’s application portfolio by delivering actionable penetration testing results in as little as 24 hours. AI-assisted development enables organizations to ship software faster than ever, while attackers are using AI to automate reconnaissance and accelerate exploitation. Pentesting performed quarterly or even monthly, can no longer keep pace. As security teams face growing attack surfaces and constrained budgets, organizations need … More → The post Cobalt adds Autonomous Pentest to scale application security testing appeared first on Help Net Security.

Such an attack could impact physical security controls. View CVE Details Affected Products Johnson Controls C-CURE 9000 and Victor application server Vendor: Johnson Controls Product Version: Johnson Controls C-CURE 9000 and victor: <=v2.90_v3.0 Product Status: known_affected Remediations Mitigation Johnson Controls recommends the following defensive measures to help reduce the risk of exploitation: (CVE-2026-21655) Upgrade to C-CURE 9000 / victor version 3.20 or later, which addresses the vulnerable deserialization path (LV1.1). Vendor fix Network segmentation - Isolate the C-CURE 9000 and victor application servers on a dedicated network segment and restrict access to port 8999 to only authorized systems that require connectivity. Mitigation Firewall / access control lists - Implement strict firewall rules to block all unnecessary inbound connections to port 8999 from untrusted network segments. Mitigation Intrusion detection / prevention - Deploy IDS/IPS signatures tuned to detect known .NET deserialization exploit payloads (e.g., ysoserial.net patterns) targeting port 8999. Mitigation Application whitelisting - Enforce application whitelisting on application server hosts to prevent unauthorized executables from being launched by the server process. Mitigation Least privilege - Ensure the application server process runs with the minimum privileges necessary, reducing the impact of successful exploitation. Mitigation Monitor and audit - Enable detailed logging on application server hosts and monitor for anomalous process creation by SoftwareHouse.CrossFire.Server.exe. Mitigation Disable unnecessary services - If the ClientConnectionManager_NF.SynchronousServerNotification callback interface is not required, disable or restrict it to reduce attack surface.

An attacker with physical access to the device and one able to compromise the device through a separate, unrelated flaw, could potentially read this data in plaintext. Exploitation does not require network access and is limited to the local device environment. View CVE Details Affected Products Johnson Controls XAAP Android Vendor: Johnson Controls Product Version: Johnson Controls XAAP Android: <1.53 Product Status: known_affected Remediations Vendor fix Johnson Controls recommends users update the XAAP Android application to version 1.53 or later, which contains the fix for this vulnerability. Mitigation Johnson Controls recommends users restrict physical access to devices running the XAAP Android application. Mitigation Johnson Controls recommends users ensure devices are hardened with up-to-date Android OS versions, device encryption enabled, and screen lock protections in place. Mitigation Johnson Controls recommends users implement a Mobile Device Management (MDM) solution to enforce security policies, including encryption requirements, application whitelisting, and remote wipe capabilities. Mitigation Johnson Controls recommends users Avoid rooting or jailbreaking devices used in production environments, as this weakens OS-level security controls that help protect local application data.
