Security Brief: The forgotten NAS is back in the crosshairs
Patch the office NAS now: Synology has warned that attackers are targeting devices running outdated DiskStation Manager (DSM), turning a quiet, dependable storage box into a high-impact ransomware target. The company’s October 29, 2026, press release says threat actors are exploiting a vulnerability patched in December 2024 to encrypt data and demand ransom, and urges users on vulnerable versions to update DSM immediately and enable automatic updates. The warning points to advisory Synology-SA-24:20.
Reports identify the ransomware as C3RB3R, also written LOCK3D, a variant of the Cerber family that has targeted NAS devices for years. Encrypted files receive the .L0CK3D or .LOCK3D extension, while a read-me3.txt ransom note appears in every folder and directs victims to a Tor site. According to a bulletin from Chinese security vendor 360, the malware uses ChaCha8 encryption and protects its keys with RSA-2048; 360 says it has received Synology-related help requests since early October.
The reports describe two serious vulnerability paths that administrators need to understand. First, CVE-2026-13639 and CVE-2026-13684, both rated CVSS 9.8, were patched by Synology on September 18, 2026, in Synology-SA-26:13. These remotely exploitable, unauthenticated flaws can allow arbitrary file reads and writes. Synology lists no mitigation for the vulnerabilities: updating is the protection. Yet reports indicate that many devices remained unpatched a month after the fixes were released.
The second path is older: CVE-2024-10441, also CVSS 9.8, is an unauthenticated remote code execution flaw discovered at Pwn2Own 2024 and patched in December 2024. Synology’s October 29 alert points to this vulnerability. A recently published GitHub proof of concept demonstrates how the DSM login page’s “username” field can be used to inject environment variables into a daemon running as root. Reporting has connected the ransomware activity to both the older vulnerability and the 2026 flaws, but that does not establish that every incident used the same entry point. The security takeaway is clear regardless: keep DSM current and reduce exposure.
The scale makes this more than a niche storage issue. Shadowtracker, operated by Shadowserver, tracks more than 380,000 internet-exposed Synology NAS devices, according to BleepingComputer’s November 2 report. Exposure does not mean every device is compromised, but a NAS that has sat unpatched because “it just works” is an avoidable risk for a small business. Network Repair1’s remote support services can help businesses strengthen patch management and maintain their systems.
Practical NAS protection checklist
- Update DSM immediately: Install at least DSM 7.4-90075, 7.3.2-86009-4, 7.2.2-72806-9, or 7.2.1-69057-12, depending on the primary DSM version.
- Enable automatic DSM updates: Keep security fixes moving onto the device instead of relying on a future reminder.
- Remove direct internet exposure: Delete port forwards to the DSM interface, and use a VPN such as Tailscale or WireGuard for remote access.
- Update packages: Patch PHP, Mail Station, Synology Calendar, and other installed packages, then remove the ones no longer in use.
- Harden accounts: Disable the default administrator account, enable two-factor authentication, and turn on automatic IP blocking.
- Protect recoverability: Use write-protected snapshots on shared folders and keep at least one offline backup. A NAS with RAID is not a backup.
Patching discipline beats paying ransom, and layered protection can keep a ransomware incident from becoming a business-wide data recovery crisis.
Desk Upgrade: ASUS ZenScreen MS27UC 27-inch 4K HDR smart monitor
A smart monitor can serve as both a desktop display and a standalone screen, and the ASUS ZenScreen MS27UC brings those roles together in a 27-inch format. As reported for November 2, it is on sale at Amazon for $199 shipped, an all-time low and 55% below its $449 launch price; it had recently been selling near $330. Prices and availability can change.
The 27-inch IPS panel delivers UHD resolution of 3840 × 2160 with 99% sRGB coverage. At this size, 4K works out to roughly 163 pixels per inch, making text and fine interface details genuinely sharp for everyday work and content creation. HDR is included, but at this price it is best treated as a feature rather than a promise of reference-grade HDR performance.
Google TV is built in, with access to more than 10,000 apps, including Netflix and YouTube, so streaming does not require a separate stick or a connected PC. That also gives the display a second job as a meeting-room or break-room screen when the computer is off. Harman Kardon-certified 2 × 5W front speakers and a bundled remote round out the TV-like setup.
For a desk, USB-C offers up to 90W Power Delivery, so a compatible laptop can run and charge through one cable. HDMI, DisplayPort, a USB hub, Miracast, Chromecast support, and VESA mounting add flexibility, while a three-year warranty with advanced replacement is a welcome support detail. It is a practical fit for a small office or content-creation desk that needs one display to cover both work and downtime.
The practical takeaway
Treat the NAS as critical infrastructure, not a set-and-forget filing cabinet: current firmware, restricted remote access, hardened accounts, and recoverable backups reduce the impact of a compromise. For the desk, the MS27UC combines crisp 4K productivity with convenient built-in streaming, without pretending its HDR is a studio reference display.
