Ransomware attacks on enterprises of all sizes, across all industry sectors, are on the rise. From our frontline vantage point, conducting over 3,000 incident response engagements a year, we know that every organization can be a victim because a successful ransomware attack is within the reach of cybercriminals everywhere.

Some threat actors are meticulous planners. They deftly map out internal networks to identify core business functions and sensitive data storage, even going so far as to research a company’s financial results to gauge how much they can afford to pay. At the other end of the spectrum, creators of “ransomware-as-a-service,” who simply ask for a percentage of the ultimate ransom, have opened the door to another class of attackers to pursue attacks with minimal risks against a wider range of targets.
Proactive Preparation Is the Best Protection Against Ransomware
While completely preventing ransomware attacks is nearly impossible, security and risk management professionals can take proactive steps to neutralize or mitigate their harm. Basic cyber hygiene remains fundamental. First, that means taking the time to accurately and regularly document the entire configuration of your network.
When a local government was victimized by ransomware, it impacted the municipality’s police and fire dispatch systems, online utility payment system, centralized accounting system and many other critical segments on its network. Unfortunately, the IT director was unaware of how many servers were on the network. This lack of awareness delayed the initial remediation, especially when combined with limited viable backups for restoration.

Second, data mapping inventories are more important than ever. Starting last year, many ransomware actors threatened to release stolen data to pressure victims into paying ransoms. Almost overnight, ransomware attacks morphed from mainly expensive operational disruptions to crises fraught with regulatory data privacy and breach notification issues. Knowing what kind of data you have and everywhere it is collected, used and stored is imperative.
