A novel attack technique could be weaponized to rope thousands of public domain controllers (DCs) around the world to create a malicious botnet and use it to conduct powerful distributed denial-of-service (DDoS) attacks. The approach has been codenamed Win-DDoS by SafeBreach researchers Or Yair and Shahak Morag, who presented their findings at the DEF CON 33 security conference today. "As we explored the intricacies of the Windows LDAP client code, we discovered a significant flaw that allowed us to manipulate the URL referral process to point DCs at a victim server to overwhelm it," Yair and Morag said in a report shared with The Hacker News. "As a result, we were able to create Win-DDoS, a technique that would enable an attacker to harness the power of tens of thousands of public DCs around the world to create a malicious botnet with vast resources and upload rates. All without purchasing anything and without leaving a traceable footprint." In transfor...

Cybersecurity researchers have presented new findings related to a now-patched security issue in Microsoft's Windows Remote Procedure Call (RPC) communication protocol that could be abused by an attacker to conduct spoofing attacks and impersonate a known server. The vulnerability, tracked as CVE-2025-49760 (CVSS score: 3.5), has been described by the tech giant as a Windows Storage spoofing bug. It was fixed in July 2025 as part of its monthly Patch Tuesday update. Details of the security defect were shared by SafeBreach researcher Ron Ben Yizhak at the DEF CON 33 security conference this week. "External control of file name or path in Windows Storage allows an authorized attacker to perform spoofing over a network," the company said in an advisory released last month. The Windows RPC protocol utilizes universally unique identifiers (UUIDs) and an Endpoint Mapper (EPM) to enable the use of dynamic endpoints in client-server communications, and connect an RPC clien...

Cybersecurity researchers have disclosed vulnerabilities in select model webcams from Lenovo that could turn them into BadUSB attack devices. "This allows remote attackers to inject keystrokes covertly and launch attacks independent of the host operating system," Eclypsium researchers Paul Asadoorian, Mickey Shkatov, and Jesse Michael said in a report shared with The Hacker News. The vulnerabilities have been codenamed BadCam (aka CVE-2025-4371 ) by the firmware security company. The findings were presented at the DEF CON 33 security conference today. The development likely marks the first time it has been demonstrated that threat actors who gain control of a Linux-based USB peripheral that's already attached to a computer can weaponize it for malicious intent. In a hypothetical attack scenario, an adversary can take advantage of the vulnerability to send a victim a backdoored webcam, or attach it to a computer if they are able to secure physical access, and remot...

Cybersecurity researchers have uncovered multiple security flaws in Dell's ControlVault3 firmware and its associated Windows APIs that could have been abused by attackers to bypass Windows login, extract cryptographic keys, as well as maintain access even after a fresh operating system install by deploying undetectable malicious implants into the firmware.

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...
