Ransomware attacks on law firms haven’t slowed down — they’ve gotten worse. Since the early wave of Cryptolocker attacks, ransomware has evolved into a multi-billion-dollar criminal industry, with law firms consistently ranked among the most targeted organizations due to the sensitivity of the data they hold and their historically under-resourced IT security posture.
The good news? If your firm is using NetDocuments, your documents are protected in a way that most attorneys don’t fully understand — and that understanding is worth having.
What Ransomware Actually Does
Ransomware is a type of malicious software that encrypts files on your computer and any connected storage, making them completely inaccessible. Once your files are encrypted, attackers demand payment — typically in cryptocurrency — in exchange for a decryption key. There’s no guarantee they’ll actually provide the key even if you pay.
Here’s how a typical attack unfolds:
Someone in your office clicks on a malicious link or email attachment — often something that looks completely legitimate, like a court filing notification or a vendor invoice. The ransomware silently installs itself, then begins scanning your computer for files to encrypt. It doesn’t just target your local hard drive. It crawls mapped network drives, shared folders, and any cloud sync tools connected to your machine.
This last part is critical for understanding why how your documents are stored matters so much.
The Cloud Sync Problem — And Why NetDocuments Is Different
Tools like Dropbox, Google Drive, and OneDrive are popular and useful, but they work through a local sync folder. Files live on your hard drive and get mirrored to the cloud. When ransomware encrypts those local files, the sync client dutifully pushes the encrypted (now corrupted) versions up to the cloud — and then syncs those corrupted files back down to every other device connected to the same account. The “cloud backup” becomes the vector for spreading the damage.
NetDocuments works fundamentally differently. It’s a true cloud-based document management system, meaning your documents actually live on NetDocuments’ servers, not on your local machine. When you open a file, it’s temporarily downloaded to your computer for editing, then checked back in to the server when you close it. There are no permanently mapped drives sitting on your network and no local sync folder for ransomware to discover and encrypt.
If someone in your firm clicks a bad link and gets hit with ransomware, the attack is essentially contained to that one machine. Your NetDocuments repository remains untouched.
What About ndSync?
ndSync is NetDocuments’ optional desktop sync tool — think of it as Dropbox-style functionality built specifically for NetDocuments. It allows users to keep selected folders synced locally for offline access or faster performance.
If your firm uses ndSync, you do have some local exposure. Files in synced folders on an infected machine could be encrypted. However, NetDocuments has a built-in safeguard specifically for this scenario called the Circuit Breaker.
Circuit Breaker monitors the pattern of changes being synced back to NetDocuments. If it detects an abnormal volume of file modifications in a short period of time — the telltale signature of ransomware encryption — it automatically suspends syncing for that user before the damage can propagate to the cloud repository. It’s not foolproof, but it’s a meaningful layer of protection that most local sync tools lack.
The practical guidance here: if your firm doesn’t have a specific business reason to use ndSync, you don’t need it. Most NetDocuments users work entirely through the web interface or the Word/Outlook integrations without ever needing desktop sync.
A Word on “Fake Cloud” Products
Not all document management systems that claim to be cloud-based actually are. When cloud computing became the industry standard, a number of legacy software vendors scrambled to offer a cloud option without rebuilding their product from scratch. The workaround many chose was to host Windows servers with their own on-premise software installed, then give users remote desktop access to those servers.

This is sometimes called “hosted” or “private cloud” — and it’s meaningfully different from true cloud architecture. Those remote Windows servers have the same vulnerabilities as any other Windows machine on a network. Ransomware can and does hit hosted server environments. We’ve seen it happen during migrations, where a firm’s legacy system gets hit mid-project.
When evaluating any document management system, it’s worth asking directly: where do the files actually live? Are they on a Windows server that someone is remoting into, or on a purpose-built cloud platform? The answer matters.
The Bottom Line
Ransomware is a real and ongoing threat to law firms. Protecting your documents starts with understanding how your document storage actually works — not just what your vendor calls it in a brochure.
NetDocuments’ true cloud architecture means that in the most common ransomware scenarios, your document repository is simply not in the attack path. Combined with features like Circuit Breaker for ndSync users, it’s one of the platform’s more practical security advantages that doesn’t get talked about enough.
If you’re currently storing documents in a local sync folder, a mapped network drive, or a hosted Windows environment, and you’re worried about ransomware exposure, it’s worth discussing your options.
Ready to Protect Your Firm’s Documents?
If you’re still relying on mapped network drives, a file sync tool, or a legacy “hosted” system to manage your documents, your firm has more ransomware exposure than it needs to. Moving to a true cloud-based DMS like NetDocuments is one of the most practical steps you can take to reduce that risk — and the transition is more straightforward than most firms expect.
Optiable has helped over 550 law firms implement and migrate to NetDocuments since 2010. Whether you’re starting from scratch, migrating from Worldox or another legacy system, or just trying to figure out if your current setup is leaving you vulnerable, we’re happy to take a look.
