Ransomware is a form of malicious software that infects devices, encrypts data, and demands a ransom for its release. By developing an understanding of how ransomware spreads, you’ll be able to protect your systems and data from these attacks.
Ransomware can quickly move through networks and devices, so it’s imperative for businesses to implement adequate security measures. Now, let’s take a look at how ransomware spreads in more detail.
Different Ways Ransomware Spreads
Once a ransomware threat actor, or self-propagating ransomware, is inside your network, there are several common ways the threat actor or ransomware will spread to devices and networks:
- Remote Services: Ransomware threat actors may abuse, hijack, or exploit the remote services within your organisation to move between systems and infect them with ransomware.
- Network shares: Once a device is infected, ransomware can spread to other devices which are on the same network, particularly if file-sharing is enabled.
- Software Deployment Tools: Ransomware threat actors may compromise software used by network administrators to deploy software or configuration changes. If compromised, these softwares can be used to install the ransomware on multiple devices across the network.
- File Sharing: Adversaries may deliver ransomware payloads to remote systems by uploading the ransomware content to shared storage locations, such as cloud-based file sharing platforms or internal code repositories.
- Exploit kits: These kits take advantage of security vulnerabilities in outdated software, enabling ransomware to infiltrate and spread between systems without the user’s knowledge.
- Internal Phishing: After gaining access to one user’s accounts within the environment, adversaries may launch phishing attacks from an internal employees account to deliver the ransomware via email.
- Infected USB drives: Removable devices can transfer ransomware from one computer to another.
How to Prevent Ransomware from Spreading
- Use reliable endpoint protection solutions and software, such as EDR and EPP, with ransomware protection.
- Regularly update all software to patch vulnerabilities.
- Train employees to be able to spot phishing emails and avoid suspicious files and downloads.
- Limit network access to sensitive data and systems.
Consequences of Ransomware Spread
- Data encryption: Ransomware locks files, making them inaccessible until a ransom is paid.
- Network disruption: Ransomware can spread through networks, affecting multiple systems and causing operational downtime.
- Financial loss: Businesses may face significant costs due to downtime, data loss, and ransom payments.
Understanding how ransomware spreads will help your business to prevent attacks and add an extra layer of security protection. With robust security practices, you can reduce the risk of ransomware infections and limit their impact on your operations.
