QNAP Urges Users to Update NAS Devices to Prevent Deadbolt Ransomware Attacks

May 20, 2022
Taiwanese network-attached storage (NAS) devices maker QNAP on Thursday warned its customers of a fresh wave of DeadBolt ransomware attacks. The intrusions are said to have targeted TS-x51 series and TS-x53 series appliances running on QTS 4.3.6 and QTS 4.4.1, according to its product security incident response team.  "QNAP urges all NAS users to check and update QTS to the latest version as soon as possible, and avoid exposing their NAS to the internet," QNAP  said  in an advisory. This development marks the third time QNAP devices have come under assault from  DeadBolt ransomware  since the start of the year. In late January, as many as 4,988 DeadBolt-infected QNAP devices were identified, prompting the company to release a forced firmware update. A second uptick in new infections was  observed  in mid-March.  DeadBolt attacks are also notable for the fact that they allegedly leverage zero-day flaws in the software to gain remote access...

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...
