Introduction

A terrifying new security vulnerability uncovered by Dutch researchers has put millions of popular storage devices at risk, and it might affect you! This zero-click flaw, as dubbed by experts, impacts a widely used photo application that comes pre-installed on many network-attached storage (NAS) devices manufactured by the Taiwanese company Synology.

Nature of the Vulnerability

The zero-click nature of this vulnerability is particularly concerning: users don't need to interact with anything for their devices to be compromised. Hackers can gain unauthorized access to both personal and corporate files, implant backdoors, and even unleash ransomware to lock users out of their data.

Affected Devices

The photo application in question, SynologyPhotos, is found in various NAS models, including the much-acclaimed BeeStation line, and is favored by users of the DiskStation series, which allows for expandable storage. The NAS devices have been a target for ransomware attacks since at least 2019, with multiple users reporting incidents as recently as this year, highlighting a growing trend of escalating attacks.

Discovery of the Flaw

In a groundbreaking discovery made during the Pwn2Own hacking contest in Ireland, security researcher Rick de Jager from Midnight Blue pinpointed this vulnerability within just two hours. Alongside his team—Carlo Meijer, Wouter Bokslag, and Jos Wetzels—he conducted an extensive scan of internet-connected devices and unearthed hundreds of thousands of Synology NAS devices exposed online. Alarmingly, they estimate that millions of additional devices are also accessible and susceptible to exploitation.

Risk Multiplied

Just last week, researchers alerted Synology about the flaw, which could become a goldmine for cybercriminals. Network-attached storage systems, serving as repositories for vast amounts of data, are particularly enticing targets for ransomware operations. Because many users connect their Synology devices directly to the internet or utilize the company's QuickConnect service for remote access, the risk multiplies significantly. Notably, the specific vulnerability resides in an area of the photo application that does not require any authentication, allowing attackers to exploit it directly without needing to breach any security gateways.

Implications for Sensitive Industries

What does this all mean? Cybersecurity specialists have identified vulnerable Synology NAS devices serving sensitive industries, including law enforcement agencies in the U.S. and France, law firms across several countries, and operators in the freight and oil sectors in Australia and South Korea. The implications could be dire for these entities, which handle critical corporate documents, evidence for legal cases, and essential operational data.

Broader Threats

But the threat doesn't stop at ransomware and data theft. Attackers could further hijack these compromised systems to create a botnet for a variety of malicious operations, akin to the notorious Volt Typhoon hackers who utilized infected routers to propel their espionage activities.

Response from Synology

Despite the serious nature of this vulnerability, Synology has faced criticism for its communication regarding the issue. The company has released two security advisories labeling the flaw as "critical," but it remains unclear how many users have learned about the patches that have been issued. Distressingly, Synology's NAS devices lack automatic update capabilities, leaving countless customers exposed. There's even a significant risk that with the release of these patches, attackers could now reverse-engineer the fixes to develop new exploit techniques.

Conclusion

As users of Synology and network-attached storage devices, it's crucial to stay informed, check for updates, and apply the necessary patches to avoid becoming another statistic in this alarming security crisis. This might be the time to rethink your storage solution!
