Ransomware attacks severely threaten organizations, affecting their operating ability and often requiring a month or more for recovery. Understanding what happens during such an attack and knowing the necessary steps for securing your organization afterward is crucial.
Understanding Ransomware Attacks
Ransomware is malicious software that encrypts an organization’s data, rendering it inaccessible. The attackers demand a ransom for the decryption keys needed to regain access. Organizations in every sector are vulnerable, but attackers typically target businesses based on two primary factors:
- Opportunity: Companies with smaller security teams, limited IT resources, or data-rich environments.
- Potential Financial Gain: Entities requiring immediate access to their files, such as legal firms or government agencies, are more likely to pay ransoms quickly.
Attackers use various methods to gain access, including phishing, exploiting remote access vulnerabilities, compromising privileged accounts, and exploiting unpatched software vulnerabilities. Before encrypting data, attackers may steal copies to threaten with “double extortion,” where they demand a ransom to avoid data leaks.
Understanding Ransomware Attacks
Immediate Actions During a Ransomware Attack
A noticeable notification will often flash on the screen when a ransomware attack occurs. Quick isolation of the infected device is essential to prevent the spread. Disconnect network and data cables and USB drives, and turn off Wi-Fi and Bluetooth connections.
Remaining calm is critical. Practicing ransomware simulations can help prepare your team for actual incidents. Here are the steps to follow:
Notify the Organization:
- Centralize all communication to avoid misinformation and confusion.
- Alert everyone in the organization to the threat.
- Direct employees to isolate suspected infected devices and reset all credentials and incredibly privileged accounts.
Identify the Ransomware:
- Use malware scanning tools or your Security Operations Centre to identify the ransomware variant.
- Document the attack details, including the date, time, file details, first signs of ransomware, affected devices, and actions taken immediately before the attack.
Immediate Actions During a Ransomware Attack
Should You Pay Ransom?
Experts and federal agencies advise against paying the ransom. Statistics show that only 60% of organizations regain access to their data after payment, and even then, there is no guarantee that the data is safe. Furthermore, 18% of victims who paid still had their data exposed on the dark web.
Removing Ransomware from Devices
Removing ransomware takes more work. A complete factory reset is often required, which can result in data loss. Professional support is recommended to use appropriate decryption tools and safely restore operations.
Recovering Data from Backups
Maintaining up-to-date backups is the most effective way to recover from a ransomware attack. Follow the ‘3-2-1 rule’—keep three copies of your data in two locations, with one copy offline. Before restoring data, scan for malware and ensure backups connect only to clean devices to avoid re-infection.
Reporting the Attack
After restoring operations, report the ransomware attack to relevant authorities, such as the CISA in the US or the NCSC in the UK. This helps agencies track ransomware trends, develop remediation tools, and prevent further attacks.
Protecting Against Future Ransomware Attacks
Protecting Against Future Ransomware Attacks
End-user behavior is one of the best defenses against ransomware. Regular training on security basics and continuous reinforcement is vital. Key practices include:
- Updating devices and enabling automatic updates.
- Enabling multi-factor authentication.
- Performing regular backups.
- Controlling access to devices and data.
- Activating ransomware protection features.
Conclusion
Ransomware attacks are a growing threat with significant operational impacts. Immediate isolation of infected devices, calm and coordinated communication, and professional support are critical in managing an attack. Avoid paying ransoms and rely on well-maintained backups for data recovery. Report attacks to authorities to aid in broader cybersecurity efforts. Continuous end-user training and strict security practices are essential to protect against future attacks.
