Nerve Center: Protect Your Network Against New Ransomware Strains with Our Latest RanSim Update

Ransomware Simulator RefreshRansomware continues to be a major threat for all organizations and, according to the Verizon 2023 Data Breach Investigations Report, is still present in 24% of breaches.

The ransomware strain DJVU (a variant of STOP) is the most widespread file-encrypting virus of 2022/2023, gaining access to systems through malicious downloads. DJVU is to blame for attacks on computers and servers running Windows OS, impacting hundreds of thousands of organizations. Another strain, Phobos, primarily targets small businesses through phishing emails to hijack Remote Desktop Protocol (RDP) connections.  Phobos not only encrypts your data, it can shut down operating system processes and disable recovery mode on Windows machines.

If your organization is receiving phishing attacks or dealing with customers that aren’t secure, then you could be at risk. That's why we've updated our Ransomware Simulator tool, “RanSim,” to add two new ransomware scenarios you can test on your network! These new scenarios simulate ransomware strains like DJVU and Phobos that exploit users and vulnerable devices, encrypting copies of attacked files and deleting the originals.

RanSim helps you understand the effectiveness of your existing network protection against the latest threats. This free tool will simulate 24 ransomware infection scenarios and 1 cryptomining infection scenario to show you if a workstation is vulnerable to infection.

“Ransomware keeps evolving and remains a threat to ALL organizations. We want IT professionals to have an easy way to stay on top of new threats and be better prepared to protect their organization,” said Stu Sjouwerman, chief executive officer, KnowBe4. “RanSim is free of charge and is here to help IT managers implement strategies that stop the spread of ransomware and build a stronger security culture.”

Now available in English, French (Europe) and Spanish (LATAM).
