How Ransomware Gets In Through One Open Port
Port 3389 left open to the internet is the single most common ransomware entry point for small businesses. Here's how attackers find it, what happens next, and what to do about it.
Dental clinics
A fixed-price dental clinic cybersecurity assessment. We check your practice system, X-ray station, email and booking - exactly where an attacker looks for a way in. Free PreScan in 24 hours, full report in 5 business days. No IT department required on your end.

The honest version
This isn't opinion - it's what the last three years of Verizon DBIR4 and IBM breach reports2 show plainly about small healthcare businesses.
Medical records sell for up to 50× more on dark-web markets than stolen payment cards, because they contain full identity, health history, and payment data in one file - perfect for identity fraud, insurance fraud, and targeted extortion.
You can't operate without digital X-rays and scheduling. Every day your systems are encrypted is a day of cancelled appointments, rescheduled patients, lost deposits, and - worst - patients who quietly don't come back. Industry recovery time for ransomware in healthcare SMBs averages multiple weeks.
Most dental clinics run a mix of consumer-grade routers, unpatched Windows, remote-access software for the practice manager, and WordPress booking sites. To a scanner running across every IP range on the public internet, you light up.
The assessment
We check whether your practice software (Dentrix, Eaglesoft, Open Dental, Curve Dental, Dentimax) is reachable from the internet - through open RDP, TeamViewer or AnyDesk. An exposed practice system is the most common ransomware entry point.
X-ray, panoramic and CBCT workstations (Romexis, Carestream, DEXIS, Vatech) often run on ageing Windows on the same network as reception. We check they are not internet-facing and are segmented from the rest of the clinic.
SPF, DKIM and DMARC configuration for your domain (e.g. info@my-clinic.com). Without them, anyone can send a patient or your bookkeeper an email that looks like it came from you - the opening move in invoice-redirect fraud.
We check practice email addresses against breach feeds (Have I Been Pwned and dark-web), plus the common clinic pattern of one shared reception login. One leaked password is usually the whole path into patient records.
Your online booking system (custom, WordPress, or third-party) and its payment-processor integration put patient data and money in one place. We look for injectable forms, outdated plugins and exposed admin panels.
Whether your record backup is reachable from the internet (and therefore by ransomware), whether an offline or immutable copy exists, and whether it meets the 3-2-1 rule. A backup nobody has tested is not a backup - it is hope.
The real cost
Patient records are ePHI under HIPAA. A breach triggers OCR investigation; penalties range from $137 to $2.07M per violation category. OCR issued $6.6M in fines in 2025 alone — dental practices are not exempt. Inadequate risk analysis is the most cited violation.
That's the IBM 2024 average cost of a breach for organisations under 500 employees. Legal, notification, remediation, and lost business combined. The clinic-specific number is typically lower, but rarely under $100k once HIPAA counsel and patient-notification logistics are included.
A single breach-notification letter sent to your patient list is the business-ending event in a referral-driven practice. Unlike enterprise, you don't have a PR firm to absorb the story. Recovery of trust takes years - if it happens.
How it plays out in practice
None of these require you to be an "interesting" target. They all start with something a scan finds in the first few hours.
The manager works from home, so the clinic PC is exposed to the internet. A bot finds it within hours, brute-forces a weak password, and encrypts the entire record system. The ransom note is on the reception screen on Monday morning.
Reception receives an email dressed up as an insurer notice or an e-invoice. One click installs malware or harvests the practice-system password. Reception clicks dozens of emails a day - it is the weakest link.
Without proper DMARC, an attacker spoofs your domain and emails your bookkeeper or supplier with a 'changed account number.' The money leaves before anyone notices. The most common real financial loss in SMBs.
The PC driving the panoramic or CBCT unit, connected to the network for remote servicing, is publicly visible. The attacker walks into the clinic network through it - bypassing reception and every "defence" you thought you had.
The online-booking password leaks in another vendor breach. Because the team reuses the same password everywhere, the attacker logs into the appointment calendar - and from there, every patient contact detail.
See what a real report looks like
We've redacted the name and domain. Everything else is the real output - the findings, the severity scoring, the prioritised action list, and the plain-English explanation your practice manager can hand to your IT provider on the same day.
Deliverables
Every clinic that orders the full assessment gets the same package - no tiers, no upsells, no "enterprise only" features held back.
Pricing
You start free. You only pay if there is something to fix. The CyberAudyt price is fixed - regardless of how many workstations or locations you run.
results in 24 h
Passive external scan of your clinic. We show what is visible from the internet - with zero access on your end. Answers the question "is there even anything to worry about."
report in 5 business days
Full external assessment with manual verification: practice system, X-ray/PACS, email, booking, backup. Plain-language report with prioritised fixes and a 30-minute call. Fixed price regardless of how many workstations you run.
once remediation is done
After you close the gaps, we re-check that the fixes actually worked - at half the CyberAudyt price for clinics that already completed one. Proof, for you and your patients, that the holes are shut.
Fixed price - no hourly billing, no surprises. Larger clinic groups, or when a corporate client requires it: a full penetration test is also available.
Guarantee: if CyberAudyt doesn't surface at least 3 actionable findings, you pay nothing.
