Win-DoS’ Zero-Click Exploit Could Weaponize Windows Infrastructure for DDoS Attacks

Win-DoS’ Zero-Click Exploit Could Weaponize Windows Infrastructure for DDoS Attacks

Security researchers have identified a "zero-click" denial-of-service (DoS) exploit that can covertly turn Microsoft Windows Domain Controllers (DCs) into a global botnet. DDoS attacks increased by 56% year-over-year in late 2024, with Cloudflare blocking an attack that peaked at 7.3 Tbps in 2025. The average minute of downtime from these attacks costs businesses approximately ,000, with incidents for small and midsize firms exceeding 0,000. The exploit, known as Win-DDoS, leverages the Lightweight Directory Access Protocol (LDAP) client in Windows, allowing DCs to automatically target victim servers through LDAP referrals without user interaction. This results in thousands of DCs inadvertently overwhelming a target with TCP traffic. Four vulnerabilities (CVEs) related to this exploit were disclosed to Microsoft in March 2025 and addressed in subsequent patch releases in June and July 2025. These vulnerabilities include: - CVE-2025-32724: LSASS (LDAP client) - None needed, causes memory exhaustion/DC crash, patched June 2025. - CVE-2025-26673: NetLogon (RPC) - None needed, causes TorpeDoS memory crash, patched May 2025. - CVE-2025-49716: NetLogon (RPC) - None needed, causes Stateless RPC DoS, patched July 2025. - CVE-2025-49722: Print Spooler (RPC) - Authenticated user needed, causes any Windows endpoint crash, patched July 2025. The vulnerabilities indicate significant architectural flaws in the LDAP client’s referral logic and RPC interfaces. SafeBreach advises administrators to apply patches promptly and limit DC exposure to the Internet. The emergence of Win-DDoS marks a shift in attack strategies, utilizing legitimate servers for amplification without leaving malware traces, complicating detection and response efforts. Enterprises are urged to enhance their threat models and implement DoS hardening measures.

Silent Cyber Weapon Discovered: Hackers Can Now Turn Your Windows Server into a DDoS Weapon

A new attack method called Win-DDoS can turn publicly accessible Windows domain controllers into a botnet for distributed denial-of-service (DDoS) attacks, as presented by SafeBreach researchers at DEF CON 33. This method exploits vulnerabilities in Windows' Lightweight Directory Access Protocol (LDAP) client code, allowing attackers to redirect traffic from compromised domain controllers to a target server without needing malicious code or stolen credentials. The attack involves initiating an RPC request to the DCs, connecting them to the attacker's CLDAP server, and receiving a referral list that directs traffic to a single IP and port, overwhelming the victim's resources. Microsoft has issued patches for four related vulnerabilities: CVE-2025-26673, CVE-2025-32724, CVE-2025-49716, and CVE-2025-49722, which can allow unauthenticated attackers to crash domain controllers or disrupt internal systems. SafeBreach warns that enterprise security models often underestimate the risks of denial-of-service attacks on internal infrastructure. Organizations are urged to audit domain controller exposure, apply security patches, and reassess the safety of their internal networks.

No firewalls or antivirus software—this new quantum technology using magnets promises to protect your information at the subatomic level

A team from Kyoto University has developed a light source that emits single photons, enhanced in brightness by a small magnetic field, which can be used for secure quantum communications. This technology relies on the principles of quantum mechanics, making it difficult for eavesdroppers to replicate or measure the quantum states without detection. The researchers used a one-atom-thick semiconductor sheet, WSe₂, creating traps for excitons that emit photons when relaxed. Current limitations include the need for cryogenic temperatures for operation, but advancements in materials may allow for room-temperature single-photon emission. The technology has potential applications in secure communications for sensitive transactions and could evolve into compact modules for practical use. Recent studies have demonstrated successful quantum key distribution (QKD) using true single-photon sources, indicating progress in integrating quantum technology into real-world networking.

Windows 11 can’t find your printer? The instant solution!

Windows 11 may fail to recognize a printer even when it is powered on and ready. This issue can occur after system updates, restarts, or when switching to a new device. To resolve it, follow these steps: 1. Ensure all connections are secure, including checking for a loose USB cable, a powered-off WLAN printer, and the correct network connection for wireless printers. Restarting both the printer and PC may help. 2. If the printer is not recognized, manually add it by going to Settings > Bluetooth & devices > Printers & Scanners and selecting Add device. If it still doesn't appear, use the "The desired printer is not listed" option to start the setup wizard. 3. Update the printer drivers by visiting the manufacturer's website to download the latest software compatible with Windows 11 for your printer model. 4. If these steps do not resolve the issue, use the built-in repair tool by going to Settings > System > Troubleshooting > Other troubleshooters and selecting the Printers troubleshooter. If problems persist, consider the possibility that the printer itself may be faulty or outdated.
