New Ransomware Could Pose a Threat to Businesses
In recent months, cybersecurity researchers have identified a new ransomware strain affecting businesses using outdated Windows desktops and devices. This ransomware, known as ShrinkLocker, targets organizations that rely on older operating systems, potentially threatening businesses of all sizes.
What Is ShrinkLocker?
ShrinkLocker is a ransomware strain that uses Visual Basic Scripting (VBScript), an older programming language that hackers have repurposed for malicious activities. This ransomware encrypts corporate systems, causing significant disruption. But what exactly does ShrinkLocker do, and how can it impact your business?
The Impact on Your Business
ShrinkLocker primarily targets sectors like government, manufacturing, and even vaccine-related businesses. Once the ransomware identifies a machine running an outdated Windows operating system (like Vista or older), it executes its attack. However, if it detects a newer system, the malware eliminates itself.
For businesses still using vulnerable systems, ShrinkLocker shrinks non-boot partitions, which store essential company data and programs. It then exploits Microsoft’s BitLocker to encrypt this data, locking you out of your devices and causing potentially devastating downtime.
How To Protect Your Business From ShrinkLocker
Given the severe consequences of a ransomware attack, prevention is key. Implementing robust security measures now can save your company from falling victim. Below are some critical steps you can take:
Regular System Updates
Ensure your company systems are regularly updated. Businesses that remain on outdated operating systems are at a higher risk of ransomware attacks. Updating to newer versions ensures that your software has the latest security patches. Even though some zero-day vulnerabilities may still exist, regularly updating your systems is your first line of defense against most attacks.
Enhanced Security Measures
Your business needs more than just basic security tools. In addition to your firewall, consider adding cloud data loss prevention tools, spam filters, and anti-malware software. These tools can help block harmful communications and prevent data theft.
Employee Awareness Training
Human error is often the cause of successful ransomware attacks. Training your employees on the latest threats and phishing tactics is crucial. By providing cybersecurity tips, you can empower your team to spot suspicious emails, links, and malware before they cause damage. When your employees understand how to identify and avoid ransomware risks, they become a valuable line of defense.
Plan Ahead for Recovery
Even the most prepared businesses should have a contingency plan in place. If your company’s data is encrypted, it’s essential to have a backup plan for recovery. Consider scheduling a discovery call with our experts to explore your options for ransomware protection and response.
Final Thoughts
ShrinkLocker and other ransomware strains are constantly evolving. With the right tools and proactive measures, your business can avoid becoming another victim. Update your systems, strengthen your security, and keep your employees informed to stay ahead of cybercriminals.
