What is Ransomware and How Does it Affect Your Business?
Ransomware is malware that encrypts files and data so you can’t access them. It then demands a ransom payment, usually in cryptocurrency, to unlock your data. At first, ransomware was limited to attacks on random users and small criminal gangs. As ransomware matured as a business, these gangs became more sophisticated and targeted enterprises using better-crafted malware that evaded antimalware scanners.
Some of these gangs also exfiltrate your data and threaten to release it on publicly available websites as an additional extortion method. This double extortion drives you to pay even higher ransom payments.
What makes ransomware so successful is its ability to disrupt business operations with little cost for attackers. The COVID-19 pandemic accelerated this trend by forcing employees to work remotely, blurring their personal and professional digital environments and providing attackers with more opportunities to exploit vulnerabilities.
Attackers often target sectors with high profit potential, such as education, healthcare and manufacturing. These disruptions have wide ripple effects throughout society, impacting individuals whose lives depend on the service or product. This has helped to drive widespread public outrage and sway policymakers to invest in cybersecurity strategies that prioritize protecting the business and the people who depend on it.
The most effective way to defend against ransomware is a comprehensive cyber defense strategy. This includes implementing multiple layers of protection and teaching your workforce how to identify and report suspicious behavior. It’s critical to create secure backups of your important data on a regular basis and never click on e-mails or attachments from unknown sources. In addition, it’s best to keep your computer on at all times and not power it down, as some ransomware variants use volatile memory when attempting to spread to other computers.
