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 theirRead More »New Win-DDoS Flaws Let Attackers Turn Public Domain Controllers into DDoS Botnet via RPC, LDAP

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 theRead More »Researchers Detail Windows EPM Poisoning Exploit Chain Leading to Domain Privilege Escalation

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 sharedRead More »Linux-Based Lenovo Webcams’ Flaw Can Be Remotely Exploited for BadUSB Attacks

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.Read More »Researchers Reveal ReVault Attack Targeting Dell ControlVault3 Firmware in 100+ Laptop Models

Cybersecurity researchers have uncovered a jailbreak technique to bypass ethical guardrails erected by OpenAI in its latest large language model (LLM) GPT-5 and produce illicit instructions. Generative artificial intelligence (AI) security platform NeuralTrust said it combined a known technique called Echo Chamber with narrative-driven steering to trick the model intoRead More »Researchers Uncover GPT-5 Jailbreak and Zero-Click AI Agent Attacks Exposing Cloud and IoT Systems

Cybersecurity researchers have discovered over a dozen vulnerabilities in enterprise secure vaults from CyberArk and HashiCorp that, if successfully exploited, can allow remote attackers to crack open corporate identity systems and extract enterprise secrets and tokens from them.  The 14 vulnerabilities, collectively named Vault Fault, affect CyberArk Secrets Manager, Self-Hosted,Read More »CyberArk and HashiCorp Flaws Enable Remote Vault Takeover Without Credentials
