Ransomware Prevention in 2021

Since Double Extortion attacks have rendered data backups useless, preventing ransomware attacks remains the only pragmatic option to stop data breaches and avoid paying ransom.

Hackers leaked data of 1000 companies in 2020 for not relenting to ransomware demands*


How does double extortion make ransomware more formidable?

The University of Utah recovered their data from backups, had their systems running, and still had to pay ransom to stop hackers from leaking student data online. Hackers had exfiltrated university’s data before encrypting it. Known as double extortion, this type of attack has emerged as the latest sure-fire way of securing fat ransoms.

Ransomware actors exfiltrate data from hacked networks before encrypting it and threaten to release it if the ransom is not paid. Double extortion has rendered backups useless for organizations. To prevent most ransomware attacks, it is imperative to check the biggest source – web browsers – that brings viruses and malware into your system and lets them move laterally across the network.

90% of endpoint compromises can be prevented if the browser activity is secured **

How to combat ransomware attacks with Zero Trust

Zero Trust recommends that organizations “never trust, always verify” by localizing and isolating resources through microcore, microsegmentation, and deep visibility.

  • Reduce the exposed attack surface
  • Prevent threats with proactive security
  • Contain damage and stop it from spreading laterally
  • Enable seamless and secure access to web applications
  • Relieve security teams by moving away from alert-driven architectures
  • Choose between three options: Microsegmentation, ZTNA (Zero Trust Network Access) and Remote Browser Isolation

The best way to start the Zero Trust journey is by assessing where the risk is the highest.
If it is at the end user level, remote browser isolation will be a smart investment

How does Remote Browser Isolation help prevent ransomware attacks?

Remote Browser Isolation (RBI) contains browser activity inside an isolated environment (Zero Trust) by fetching, rendering, and executing all elements of a page away from the user’s device. It successfully protects against all ransomware attacks and spares organizations all the headaches – monetary losses, lawsuits, regulatory action, and reputational damage.

  • Prevent attacks using malicious links and websites
  • Eliminate the cost of web-based ransomware attacks
  • Reduce the number of security alerts
  • Remove browsing activity from a user’s computer
  • Enable seamless and secure access to web applications
  • Protect against malicious downloads and infected ads

Double Extortion Prevention

Instead of trying to stop users from clicking on every bad link, no matter how cleverly disguised, let Cyberinc Isla prevent double extortion ransomware attacks from succeeding.
