How to Avoid Disruptions Due to Ransomware, Malware, and Data Breaches

Healthcare Organizations Face Unprecedented Cyberattacks

It is no secret that Healthcare Providers are being targeted at an alarming rate by ransomware attacks. Due to the critical nature of health systems, attackers know they are more likely to have their ransom demands met.

Zero-day attacks have become a cause for great concern as unpatched systems are increasingly targeted due to their 
high level of vulnerability. 

Remote Code Execution (RCE) is another common attack vector used as traditional cybersecurity tools have not been 
able to adequately guard against it.

A Verizon Data Breach Investigations Report shows that attacks on servers dominate compared to those on user accounts and client devices. Furthermore, the report also shows that attacks on web application servers outpaces any other asset type.

Zero-Trust Platform for Server Workload Protection

Virsec’s groundbreaking approach delivers the highest levels of protection, with zero dwell time and low false positives. Virsec leverages security controls that embrace a modern automated “allow listing” approach — permitting only known good code (executables, libraries, and scripts) to run. All other code is explicitly denied execution — eliminating dwell time and stopping Zero-day attacks before exploitation can occur.


  • Stop known and unknown attacks
  • Protect servers, even unpatched and legacy systems
  • Reduce dwell time to zero
  • Lower false positives
  • Better performance than other security solutions

Behavior-based solutions rely on stopping the known bad but struggle with the large set of unknown executables. This “default allow” approach assumes implicit trust (the 
opposite of Zero Trust).

Virsec’s approach adopts a “default deny” policy that only allows known good code to execute and stops everything else. That’s true Zero Trust.

The Virsec Security Platform (VSP) Enables Critical Capabilities

Executable Allow Listing
  • Establish and enforce system-wide allow-listing for processes, libraries, and scripts based on trustworthiness
  • Establish trustworthiness by verifying the pristineness based on trusted publishers 
    and reputation based on our reputation database
  • Monitor deviations in run-time and mitigate any instances of modified or added executables
Application Control Policy
  • Enforce dynamic execution control on allow-listed processes to stop living-off-the-land attacks
  • Block malicious activities from the otherwise trusted operating system-related process
  • Enforce parent-child process controls to stop RCE and lateral movement
Software Integrity Assurance
  • Monitors critical application folders and directories for file I/O activity
  • Reports any changes in access privileges and file ownership in the monitored folders
vsp protection stack
Memory Exploit Protection
  • Stops process injection techniques including, but not limited to, Code Injection, Process Hollowing, and Process Doppelgänging
  • Stop dumping OS credentials from the memory of key processes like LSASS
  • Stop privilege escalation attacks like dirtypipe, dirtycow and in-memory attacks on Linux servers
  • Exploit techniques are detected and stopped in real time without the need for any signature, learning, or customization
Buffer Overflow Protection
  • Detect memory-based attacks such as buffer overflows, return-oriented programming, and other blind attack schemes on program flow, memory stack, and return addresses
  • Protects runtime execution of pre-compiled applications by automatically extracting the control flow for every executable, and enforcing any deviation during runtime
Web Protection
  • Web Application & API Protection for attacks coming via http/https channel
  • Detects OWASP Top 10 Attacks on protected web applications using deep instrumentation of application frameworks and/or web servers
  • Blocks Web-based attacks by examining the HTTP payloads and resulting transactions in the application

Impact Of Cyberattacks On Patient Care

Ransomware Time-to-Encrypt Getting Worse

Patient care and EHR systems targeted with sophisticated attacks leading to faster encryption

The speed with which attackers can discover and encrypt systems is putting organizations at even greater risk. According to IBM, ransomware attacks need less than four days to encrypt 

systems on average. Furthermore, we have already seen attacks that can compromise data within 30 minutes, e.g. the QBot malware

Expanding Healthcare Regulations for Cyberattacks

New laws to require rapid response and reporting 

The White House signed into law the Cyber Incident Reporting for Critical Infrastructure Act of 2022. This new law is applicable to public and 
private health organizations; once the proper standards are developed, the following will be in effect:
  • Critical infrastructure entities must report cyberattacks to CISA within 72 hours of discovery. 
  • Critical infrastructure entities must report ransomware payments made within 24 hours
The seven requested items include:
  • Description of the incident
  • Description of the vulnerability
  • Security defenses maintained
  • Tactics, techniques, and procedures
  • Compromised information
  • Contact information for a covered entity

Virsec Security Platform

Reduce Noise

Other solutions that rely on analysis generate so many false positive alerts that it overwhelms teams. With a positive security model and automated allow listing, you can protect legacy systems AND avoid all the alert fatigue.

Reduce Risk

Legacy applications and workloads present an open and highly vulnerable attack surface to cyber criminals. Install continuous protection for host operating systems and applications with Virsec mitigating security controls to protect legacy environments.

Reduce Cost

There are few alternatives to reducing cyber risk from legacy workloads:
(1) pay large amounts for Extended Security Updates (ESUs) and one-off security patches,
(2) do nothing or
(3) explore Virsec's mitigating controls. Option 3 delivers the highest level of protection at the most affordable investment level.
